Taking Control of Take Control Books

Take Control of Take Control Books cover

As many Joe On Tech readers know, I have been an author for over 20 years, and for the last 14 of those years, most of my books have been published by Take Control Books. In fact, I’ve written 56 Take Control titles so far (nearly a third of their catalog), and royalties from those books have been my primary source of income for a long time. It has been a pretty good gig.

In a twist I never could have predicted or even imagined just a few months ago, my company (alt concepts inc.) has acquired Take Control Books from TidBITS Publishing Inc. (owned by Adam and Tonya Engst). I can’t say I’ve ever heard of an author purchasing their publisher before, and I’m still boggling at the weirdness of it all. But this arrangment is a Very Good Thing for everyone involved.

First of all, the venerable Take Control series will continue indefinitely, with an unbroken string of new and updated titles from the usual array of popular authors (including yours truly). If we’ve handled the technical details correctly, everything that was working before should continue to work in the future (and if not, we’ll fix it). Although there are various behind-the-scenes infrastructure changes like new IP addresses and author royalties being paid from a different bank account, the transition should be essentially seamless from our customers’ point of view.

This transition means that Adam and Tonya get a much-needed change of pace. Doing the same thing for too long can lead to boredom and burnout, and I think they felt the time was ripe to explore a different direction professionally. They didn’t want to simply discontinue Take Control, because the series has been so valuable to so many people (readers, authors, and editors alike), but they needed to find it a good home while ensuring that their income didn’t suddenly dry up. Because I’ve been so deeply involved with Take Control since the beginning, I was in a unique position to take over without having to learn the business from scratch.

And so I get a new title: Publisher! I’ll still be writing books, but not as many as before, because a great deal of my time will now be spent publishing other people’s books; managing the business; and dealing with various technological, financial, and logistical matters. I’ll help to recruit and nurture more authors and editors, develop new titles, and do the various other sorts of schmoozing and networking that publishers apparently do. My wife, Morgen Jahnke, will be a big part of this business too. Her main focus will be marketing and publicity, and one of her main goals is to help Take Control books reach a wider audience. Our calculations suggest that this new arrangement will give us greater financial stability, and with luck and hard work, we might even get a bit of an income boost over what would have been possible previously. That would be nice.

Take Control has been incredibly successful as a publisher of tech-focused ebooks, and the last thing I’d want to do is muck up a system that works well. I do, however, have lots of ideas about ways in which Take Control can be improved and expanded. It will take a while to work through my to do list—everything requires time, money, or both. But I am extremely motivated to guide Take Control onward and upward. It’ll be exciting.

You may be wondering what this all means for Joe On Tech. Well, the main reason I started this site was to give a home to several of my favorite Take Control titles that Adam and Tonya were unable to keep updating. (The blog portion of the site, which was admittedly somewhat of an afterthought, didn’t get much attention because I was nearly always busy writing books!) The four current Joe On Tech books will continue to be available, both on this site and at takecontrolbooks.com. I expect to update them later this year after Apple releases the next version of macOS. At some point, I’ll probably reintegrate them into the Take Control brand, because having everything under one virtual roof will make my life simpler. Quite likely the other articles here will also move over to the Take Control site, and when that happens, I’ll probably retire the Joe On Tech brand altogether. And that’s all fine with me. The books will live on, and I’ll still have a platform to express my thoughts on technology, it just won’t be cartoon-Joe-in-a-purple-shirt everywhere.

In short, there are no problems. On the contrary, I’m thrilled to be embarking on this new adventure (or, if you will, the Pro version of the previous adventure). Off we go!

For more details about the Take Control transition, see:

Take Control of Your Digital Legacy

My 56th Take Control book, published a few days ago, is quite a bit different from anything I’ve written before. I’ll let this funny-looking guy with purple hair explain:

In the customer survey Take Control Books conducted a few months ago, the topic of one’s digital legacy was the most popular by a large margin. People are increasingly concerned about what will happen to their accounts, email, photos, and other data if they die or become incapacitated; and beyond that, how they can make sure all (and only) the data they want to pass down to future generations is preserved in a way that will still be useful decades or centuries from now. I tackle all these subjects, and more, in Take Control of Your Digital Legacy.

Take Control of Your Digital Legacy cover

We’ve already received a surprising amount of feedback. Several groups have asked me to do presentations about the material in the book, and professionals such as estate lawyers and accountants have been inquiring about how they can buy the book in bulk for their customers. Every time I turn around someone else is telling me a story involving the importance of having a plan to pass on their digital information. I’m truly amazed at the level of interest.

I wondered how enthusiastically the market would embrace a book that is about, you know, death. But as it turns out, people are finding it life-giving to consider the notion that they can take concrete action to influence the distant future. And, as I say in the book, most of the steps you take to organize and preserve your data for posterity can also have concrete benefits right now.

The book answers questions like these:

  • How can I be sure someone I trust has access to all my passwords in the event of my death or another emergency?

  • What will happen to my social media accounts (Twitter, Facebook, etc.) when I die, and do I have any say over that?

  • Is there any way I can help my heirs figure out what information I have and where to find it, without laboriously indexing zillions of files?

  • What are the options for dealing with my saved email, random files on my computer, and assorted online accounts?

  • How can I go about digitizing family photos and other memorabilia I want to pass on?

  • Are there any potential issues involved in passing on purchased media (such as music, movies, and TV shows) to an heir?

  • What are the best file formats to use if I want my data to be readable in the distant future?

  • Which storage media are most likely to be readable years from now, and what can I do to prevent data loss over time?

  • What’s the advantage of writing my own obituary while I’m still alive?

There’s much more, too. This book is appropriate for people of any age, and regardless of which platform(s) you use. Apart from a couple of spots that required a bit of technical detail, it’s written for the layperson; you don’t have to be a computer whiz to make sense of this material.

You’ll learn all the fundamentals of digital estate planning: why your regular will should be accompanied by a digital will, how to inventory your digital assets without going crazy, and how to choose a digital executor. The book even includes a free downloadable template you can fill in to express your wishes for dealing with every aspect of your digital legacy.

Take Control of Your Digital Legacy costs $15, and it’s available right now from Take Control Books. I hope you’ll find it useful.

As is my custom, I spoke to Chuck Joiner about this book on MacVoices. Have a look (or listen):

Updated Joe On Tech Guides and a New Bundle

Mac Fitness book covers

One of the occupational hazards of writing about technology is that books go out of date as hardware and software changes. In an ideal world, I’d update every one of my books each time the products they cover change. But come to think of it, I’m not sure that world would be ideal after all, because with sixty-ish books in my backlist, I would spend every waking hour doing nothing but updating books. Be that as it may, I’m delighted to say that at least the four current Joe On Tech guides have all been freshly updated to include coverage of macOS 10.12 Sierra (while continuing to support older versions of OS X going back to 10.9 Mavericks). I’m even more delighted to say that all these updates are free to everyone who owns earlier versions of the books.

Although the main change in all four titles was adding Sierra compatibility, I also took the opportunity to make a few other small additions and corrections to each title. I’d like to think all four books will remain accurate until Apple releases the next version of macOS in, I assume, late 2017, but I probably won’t be so lucky. In any case, as of September 20, 2016, the latest versions of the books are completely up to date:

If you already had an older version of one of these books, you should already have received email from me explaining how to download the latest update. If you didn’t get that message, just click the “Check for Updates” link found on the next-to-last page of your book (or thereabouts).

But wait, there’s more! Along with the new versions, I’m also now offering a special ebook bundle at a greatly reduced price. The Mac Fitness Bundle includes all four ebooks, and costs only $39.99 (that’s less than the price of three individual books). If you don’t already own these books, the bundle is a great way to learn everything you need to know to keep your Mac healthy and fit.

I discussed the updated books and the new bundle with Chuck Joiner on MacVoices. Have a look:

Take Control of Upgrading to Sierra

Take Control of Upgrading to Sierra cover

Apple released macOS 10.12 Sierra on September 20. If you’d like to upgrade but are feeling nervous or hesitant, I’d like to recommend my latest book: Take Control of Upgrading to Sierra. This is my tenth Take Control of Upgrading to… book, going all the way back to Take Control of Upgrading to Panther back in 2003. Because this book is informed by years of experience and countless test installations, you can upgrade with confidence.

As I say in the book’s introduction, upgrading doesn’t have to be a big deal. If you’ve upgraded your Mac numerous times and have excellent backups (and fast broadband), you’ll almost certainly be fine without having to read my book. But if you’ve never upgraded a Mac’s operating system before—or if it’s been years (Snow Leopard holdouts, I’m looking at you)—you may want a bit of expert advice about how to prepare your Mac, avoid (or fix) problems, and get up and running afterward with minimal fuss.

As usual, I spoke to Chuck Joiner about this book on MacVoices. Have a look (or listen):

Second Edition of Backing Up Your Mac: A Joe On Tech Guide Now Available

Take Control of Backing Up Your Mac cover

As I foreshadowed last week, the massively revised second edition of Backing Up Your Mac: A Joe On Tech Guide has been published. Although I originally thought this would be a minor update, I kept finding more things that had changed in the world of Mac backup hardware, software, and services. And, I wanted to incorporate a number of reader suggestions and requests. So the second edition has quite a bit of new stuff in it, and is also (of course) up to date with the latest version of OS X (soon to be macOS).

In the Take Control world, we normally charge an upgrade fee for new editions. I don’t mean to set a precedent for Joe On Tech guides, but for a variety of reasons it seemed like a better idea to offer this version as a free update to anyone who has the first edition. If you are such a person, you should already have received an email from me with instructions for downloading the new version (ahem, followed shortly thereafter by another message with the correct links!), but if not, please click the Check for Updates link on the next-to-last page for details.

Improve Your Mac’s Performance with Speeding Up Your Mac: A Joe On Tech Guide

Take Control of Speeding Up Your Mac cover

My lastest book, Speeding Up Your Mac: A Joe On Tech Guide, is finally available! I’ve been promising this book for quite some time, and it’s been frustrating these last several months not being able to make good on that promise. (Life has been complicated. You know how it is.) I appreciate the patience of those of you who have been waiting so long, and I’m pleased to say your wait is over.

Alert readers can probably discern from the book’s title that it has to do with improving your Mac’s performance 😀. That’s true, but there’s more to the story.

I suspect most Mac users have experienced the feeling that their Macs have gotten gradually slower over time. It’s usually a subtle thing, but one day you start noticing that things don’t feel quite as zippy as they once did. More time passes, and you notice increasing delays in opening files, loading webpages, switching apps, or whatever. And then one day you realize you’ve crossed a line and you start yelling at your Mac. (This might be more useful after macOS 10.12 Sierra ships and Macs include Siri. Can’t wait to find out.) Right around that time, Apple announces new models and your immediate temptation is to solve your speed problem by buying an entirely new Mac. And hey, who doesn’t like a shiny new computer? But you may also feel like your old Mac should have plenty of life in it and wonder whether there isn’t some way to make it feel as fast as it did when you bought it.

As a matter of fact, you can return your Mac to its formerly peppy self, and in many cases, even go beyond that. That’s what my new book tells you how to do.

The thing is, there are gazillions of websites with tips about improving Mac performance, but most of them are based solely on anecdotal evidence. You can try a bunch of these random procedures, but you have no way to know up front whether any of them will be successful, and even if your Mac is faster at the end, you may have no idea which of the things you tried solved your problem, or how to prevent slowdowns in the future.

I prefer taking a scientific approach. You can perform tests to narrow down the exact causes of speed problems, and then take just the right steps to solve those problems. Better yet, you can measure your Mac’s speed before and after any change so you know exactly whether (or to what extent) it improved things. And that’s just what my new book tells you how to do. You’ll learn the basic facts about what affects your Mac’s performance, find out which commonly recommended procedures are myths, and discover how to systematically identify and fix your Mac’s actual speed problems. The book covers everything from quick fixes to more involved hardware upgrades. And it shows you various ways to monitor your Mac’s performance in the future, so that if performance problems appear again, you can nip them in the bud.

Speeding Up Your Mac: A Joe On Tech Guide is available now in both ebook ($9.99) and paperback ($14.99) forms. As has been the case for previous Joe On Tech books, this book is based on an earlier title of mine called Take Control of Speeding Up Your Mac (last updated in 2012 and now discontinued), but it’s greatly updated and expanded. If you have the old Take Control title, click Check for Updates on the cover to learn about a special upgrade offer.

This is the fourth Joe On Tech guide (after Backing Up Your Mac, Maintaining Your Mac, and Troubleshooting Your Mac), and it completes my “Mac fitness” series of ebooks. I do plan additional Joe On Tech books (and other products) for the future—some of them dealing with the Mac, and some not. Here’s hoping life doesn’t introduce too many more complications between now and then!

Update: As usual, I did a MacVoices video interview with Chuck Joiner about the new book. Check it out!

Free Updates to My Mac Maintenance and Troubleshooting Books

Technology never sits still, and as computer hardware and software evolves, I like to make sure my books reflect the current truth. Although I can’t keep everything I’ve written perfectly up to date (I’d spend my whole life doing nothing but updates!), one of the reasons I adopted several of my Take Control books and turned them into Joe On Tech titles was that I wanted the opportunity to keep these valuable resources current, since Take Control didn’t have the resources to do so (and I can hardly blame them—after all, I have written 53 books for them so far!).

Today I’m happy to announce updates to two Joe On Tech guides. Both are free to anyone who had the previous version. I’ve already sent email to people who bought these books directly from me, informing them of the updates and how to obtain them. If you have the book and didn’t hear from me for some reason, click the Check for Updates link on the next-to-last page of the book. (If you have the paperback version of either book, I obviously can’t update that for free, but the Check for Updates URL in the printed book will tell you how to download the latest version in ebook format.)

Take Control of Maintaining Your Mac cover

First is Maintaining Your Mac version 1.1. This is a minor update to address a few small issues that appeared after the book’s original publication:

  • Added A Note to Readers, which describes all four “Mac fitness” books from Joe On Tech

  • Changed all the alt.cc and joeontech.net links to use HTTPS

  • Switched to using the term “macOS” (the new name for OS X starting with Sierra, due in late 2016) where possible

  • Updated names, URLs, and pricing for various products

  • In the sidebar Other RAM Tests, added Atomic to the list of tools for testing your RAM

  • In Exercise Your Notebook’s Battery, mentioned Apple’s advice to calibrate batteries in notebook Macs with removable batteries

  • Corrected the name of the link to click for updating Take Control ebooks in Check for Ebook Updates

  • Updated the sidebar RAM Usage Meanings to reflect the correct labels for memory usage categories in Mavericks and later

  • In Monitoring Utilities, added Checkmate to the list and included a note about a version of MenuMeters that works on 10.11 El Capitan and later

Take Control of Troubleshooting Your Mac cover

Next, Troubleshooting Your Mac: A Joe On Tech Guide has moved to version 1.0.1. In this comparatively tiny update, I’ve made just a few small adjustments to keep the book current:

  • Changed all the alt.cc and joeontech.net links to use HTTPS

  • Switched to using the term “macOS” where possible

  • Addressed a few small errors and formatting inconsistencies

  • Updated A Note to Readers (and several other portions of the book) to reflect the availability of Speeding Up Your Mac

  • Added a new utility from Micromat called Atomic to the list of tools you can use to Check Your RAM

  • Added a link to a book in Printing Doesn’t Work that, somewhat ironically, was missing only in the printed version of this book

One last thing: I’m this close to finishing a brand new, second edition of Backing Up Your Mac too! Like the others, it will be a free update (even though the changes are much more substantial). Check back in a couple of days for news.

Are Your Bits Flipped?

Are Your Bits Flipped? cover

And now for something (almost) completely different! My latest book from Take Control—#53!—is not actually a “Take Control” book at all. It’s called Are Your Bits Flipped?, and unlike my usual fare, it’s not a how-to book! Instead, it’s a collection of essays about technology misconceptions—what you might be getting wrong and why, how things really work, and how to avoid forming new misconceptions. I think you’ll find it enjoyable as well as educational.

Computers store data as a series of bits, each of which can be either a 1 or a 0. You put bits together to make bytes, and put bytes together to make kilobytes, megabytes, gigabytes, and so on. But the thing is, if even a single bit is “flipped” from a 1 to a 0 or from a 0 to a 1, that can change everything. It might lead to an error message, a crash, or worse. In other words, a tiny, simple error can have significant consequences. Likewise, when our ideas about how things work are just a tiny bit off, the resulting mistakes in our mental models can lead us to waste time, make poor decisions, and make bad matters worse.

Everyone has flipped bits (metaphorically speaking) from time to time. There’s no shame in having a flipped bit; it doesn’t mean you’re stupid or careless or inattentive. Just that you happened to miss, or misunderstand, a small piece of information, and that error had a cascading effect. This book is my attempt to reveal and correct a bunch of these common misconceptions—flipping those bits back to their correct values. I also offer some advice on keeping your bits from being flipped in the future.

About half of the chapters in the book are based on articles I wrote for the FlippedBITS series at TidBITS (although they’ve all been thoroughly updated and edited since then). The remaining chapters are in the same vein, mostly responding to questions I’ve heard or behaviors I’ve noticed that tell me someone hasn’t quite grasped the way things work. This $15 book is 190 pages long, and even at that, I had to cut a number of topics that were in the outline. If there’s sufficient interest in this book, I have many other ideas about topics that could be added in a future edition.

I hope you enjoy reading Are Your Bits Flipped? as much as I enjoyed writing it!

As is my custom, I spoke to Chuck Joiner about the book on MacVoices:

Take Control of Your Passwords, Second Edition

Take Control of Your Passwords cover

It’s the season for second editions, and hot on the heels of my updated Dropbox book, Take Control Books has released a new edition of Take Control of Your Passwords. This book is my complete guide to understanding how passwords work and dealing with the many frustrations they involve—with as little inconvenience as possible. Passwords are a pain, but they aren’t going away any time soon, and the better you understand the risks and your options for dealing with them, the safer you’ll be.

This book grew by 44 pages in its second edition. Quite a lot has happened in the world of digital security in the past couple of years, and this book now brings you up to date with the latest technologies and advice. In particular, I say a great deal more about two-factor authentication (and its close relative, two-step verification), an increasingly common way to supplement an ordinary password with extra security by requiring a secondary code or other confirmation when you log in. I also describe new gadgets, apps, and services that are designed to reduce password pain in various ways, provide a more accurate description of entropy (a measure of how hard it is to guess a password), and even include an appendix explaining the simple math you can use to calculate entropy yourself.

Because a password manager is an essential component of any solid password strategy, I’ve updated and expanded the discussions of 1Password and LastPass and added descriptions of four password managers that the previous edition of the book didn’t cover. I also detail more features that are worth thinking about, such as support for iOS browsers, Apple Watch, one-time passwords, and U2F (universal two-factor) authentication.

Take Control of Your Passwords costs $15, but anyone who had the first edition can upgrade at a discount (click Ebook Extras on the cover for details).

Here’s my MacVoices interview about the book:

Take Control of Dropbox, Second Edition

Take Control of Dropbox cover

Every day I rely on Dropbox to sync files across my devices and to the cloud, to share files with other people, and to collaborate with editors and publishers. It’s an essential part of my digital life, and it’s been changing and evolving steadily over the years. I knew my book about Dropbox was getting a little long in the tooth, but when I reviewed all the changes in the service (and its apps) since the first edition of the book, I was astonished at the length of the list. As a result, the second edition of Take Control of Dropbox has grown by over 50%—from a mere 97 pages to 151. This new book is the best way to learn what Dropbox can do for you and how to get the most from this popular cloud storage service.

If you’ve been using Dropbox for a while and haven’t kept up with the changes, a chapter at the beginning helps bring you up to date with the latest features. Every chapter has been thoroughly revised and expanded to reflect the latest Dropbox capabilities, and I’ve added new chapters about using the Dropbox website; working with the Dropbox Badge, Acrobat integration, desktop notifications, and Mac Finder integration; and collaboration features such as Dropbox Team, comments, file requests, and Dropbox Paper.

That’s just the beginning, too! Take Control of Dropbox helps you discover new and creative uses for the service, avoid or work around confusing issues, and find the most efficient ways to sync and share files on OS X, Windows, iOS, and Android.

The book is $15; as usual, discounts are available for people who purchased the previous edition (click Ebook Extras on the cover for details).

If you’d like to hear more about the book, check out my MacVoices interview with Chuck Joiner:

Take Control of 1Password, Second Edition

Take Control of 1Password cover

The Mac version of my favorite password manager, 1Password, has just been updated to version 6, with lots of great new features. (To learn more about what’s new, see my TidBITS article “1Password 6 for Mac Adds Teams, Expands Sync Options.”) For anyone interested in learning how to get the most out of 1Password (not just on OS X but also on Windows, iOS, and Android), I’m pleased to announce the publication of a massively revised second edition of my book Take Control of 1Password. The new book is 174 pages long, and costs $15. People who own the first edition can get it for half price (click Ebook Extras on the cover for details), and those who bought it in the past few months get the update for free.

There’s always a tricky line to walk when writing about a third-party product. On the one hand, I want everyone else to be as enthusiastic about this app as I am, so I’m excited to help people discover new ways to use it and figure out workflows that will make them feel it’s indispensable. On the other hand, I don’t want to make it appear more complicated than it is, and I know some people will say, “Geez, if I have to read 174 pages to make sense of this app, it must not be very user-friendly.” I sometimes worry that the mere existence of a book will backfire and turn people off, because of a feeling that apps should “just work.”

The way I like to think about it is in terms of cooking (of course). You don’t need a book to tell you how to make toast or boil water. You can feed yourself with nothing more than a microwave oven and a spoon. But if you want to make a fancier dish, you’re going to consult a recipe—and you’ll probably do that even if you’re an experienced cook. (You might also do that for meals with simple dishes but complicated logistics, such as Thanksgiving dinner.)

Same goes for software. Almost anyone can grasp the basics of 1Password without any help, but if you want to do fancy stuff—and believe me, you really do, because the fancy stuff is super cool and will save you all kinds of effort—a little bit of guidance will make it a lot easier. That’s what I do in Take Control of 1Password. I start from scratch so that beginners can find their footing quickly, but I also go far beyond the basics to cover the things power users will care about.

As usual, I spoke to Chuck Joiner about the book on MacVoices. Have a look (or listen):

As I mentioned in my TidBITS article, this book had been out of date for a very long time. Despite my discomfort that we were still selling a book that was out of sync with the app it described—the app had been updated many times since the last new version of the book—getting the two in alignment was surprisingly hard. There were a number of difficulties, but the main one was wanting to have the book match the app for more than a month or two. A typical cycle went something like this:

  • I say, “Hey, a new version of the app was released and I have a bit of free time. We should update the book next month!”

  • Take Control says, “Cool. Check with AgileBits and make sure that suits their schedule.”

  • AgileBits says, “Yeah, well, we have a major new version coming out for another platform in two months, so if you update the book now, it will be out of date almost immediately when it ships, and we’ll be back to where we are now. Maybe wait a few months to do the update.”

  • A few months pass, but by that time I’m up to my ears in another book. And as soon as that book goes out the door, something else comes up (like Apple releasing a new version of OS X) and I’m forced to spend the next several months writing or updating books to deal with whatever that new situation was.

  • Finally, I have a window of opportunity, and I say, “Hey, I have some free time. We should update the book!” And the cycle starts all over again.

I can’t tell you how many dozens of times I’ve gone through this. Not just with AgileBits, of course, but with every developer we’ve worked with. It’s nobody’s fault, and pretty much inevitable in this business. (And I’m not even mentioning times when a developer has promised us a major update in six months, so we arranged our schedules accordingly, only to see six months turn into nine, twelve, and beyond. Even then, last-minute changes to software frequently wreak havoc with our publishing process. Sigh.)

So, if you’re wondering why another favorite book of yours (say, Take Control of Getting Started with DEVONthink 2) hasn’t been updated in forever, the reason is probably something along those lines. It’ll happen. It just takes time.

Solve Mac Problems with Troubleshooting Your Mac: A Joe On Tech Guide

Take Control of Troubleshooting Your Mac cover

An occupational hazard of writing about technology for a living is receiving an endless stream of email messages from people who have read my books and articles and want me to offer personal troubleshooting advice. I try to be helpful and gracious, but the truth is that spending hours every week solving other people’s problems for free is not my idea of a good time.

And so, in a sense, one might consider my new book to be somewhat self-serving in that its purpose is to help people solve their own problems (and thus not bug me about them). I kid—sorta—but in fact I think every Mac user should have a set of basic problem-solving skills that will enable them to tackle common issues without having to call in an expert. That’s what I aim to provide in my latest book, Troubleshooting Your Mac: A Joe On Tech Guide.

The book starts with a few steps you can take to prevent problems, and then helps you assemble the tools you’ll need if and when a problem occurs. Next, I teach 17 crucial troubleshooting skills, all in simple terms anyone should be able to understand. Many of those skills come up time and again in the following chapter, which details 21 common Mac problems, each with step-by-step solutions. And, if you encounter a novel problem for which you can’t find a tidy fix in the book, another chapter helps you think like a Mac technician and work your way to a solution.

Troubleshooting Your Mac: A Joe On Tech Guide is available now in both ebook ($9.99) and paperback ($14.99) forms. This book is based on an earlier title of mine called Take Control of Troubleshooting Your Mac (last updated in 2012 and now discontinued), but it’s greatly updated and expanded. If you have the old Take Control title, click Check for Updates on the cover to learn about a special upgrade offer.

This is the third Joe On Tech guide (after Backing Up Your Mac and Maintaining Your Mac). Late this year or early next year, I plan to release the fourth Joe On Tech guide, Speeding Up Your Mac, which will again be based on an old Take Control title. After that, I plan to go branch out into other, original topics, not all of which will have to do with the Mac or even with electronic gadgets generally. Stay tuned!

Update: Here’s a MacVoices video interview I did with Chuck Joiner about the new book. Enjoy!

Upgrade to El Capitan and Master Apple Mail

Take Control of Upgrading to El Capitan cover

As has been my custom since 2003, when Apple released Mac OS X 10.3 Panther, I’ve written a book that helps people upgrade to the latest version of OS X. This morning, Apple released OS X 10.11 El Capitan, and this afternoon, Take Control published version 1.1 of my book Take Control of Upgrading to El Capitan.

Version 1.0, which was published a few weeks ago, covered the process of preparing for the upgrade. The new version (which is a free update to anyone who bought version 1.0) is roughly twice as long; it adds step-by-step instructions for downloading and running the installer and dealing with all the little surprises that may come up thereafter.

This version has been “done” for some time, but as I ran through a few test installations of the final version of El Capitan today, I noticed some changes from the GM Candidate release I’d been working with, so I updated the manuscript in order to give readers the most up-to-date instructions. If, as time goes on, I find out about any other serious anomalies, I’ll update the book yet again.

If you’re thinking about upgrading to El Capitan from an older version of OS X (even if it’s as old as 10.6 Snow Leopard), this book will help you do so safely, smoothly, and confidently.

Here’s my MacVoices interview about the book:

Take Control of Apple Mail cover

But that’s not all! Take Control has also published a greatly expanded and revised third edition of my book Take Control of Apple Mail, with 24 pages of new material. This book covers Apple’s Mail app in both El Capitan and iOS 9.

I’m happy to say that the new versions of Mail are significantly faster and less buggy than the ones they replace! Even so, Mail certainly has a lot of quirks, hidden features, and confusing user interface elements. If you want to learn Mail inside-out—from the snazzy new features to background on things like IMAP, POP, and SMTP—this book is for you.

Besides covering Mail’s most important features, the book explores ways to extend Mail with plug-ins and other third-party software, not to mention AppleScript and Automator. It even helps you become a better correspondent and bring order to an overflowing inbox.

Once again, I spoke to Chuck Joiner about this new book:

I hope you’ll enjoy these two new Take Control books. While you’re reading them, I’ll be working feverishly on the next couple of titles in my queue—Troubleshooting Your Mac: A Joe On Tech Guide and a new edition of Take Control of iCloud. See you when I come up for air!

Central Valley Buzz TV Appearance

Yesterday I was in Fresno to give a talk to the Fresno Mac-Apple Users Group. Earlier in the day, I stopped by KAIL-TV for an interview on the Central Valley Buzz show. Regular host Chuck Leonard was out for the day; Mike Briggs filled in for him. Hey, my first time on live TV! It was fun.

On the Bizarre Logic of Weather Apps

A couple of weeks ago on Twitter, I complained thus:

Weather app developers: if your app says that today’s high is 83° and that the current temp is 88°, your code has a logic problem.

Responses varied from strong agreement to reasons why developers might be doing it “wrong.” Two interesting theories appeared as to why an app might show a high temperature for the day that’s significantly below the actual current temperature:

  • Perhaps the app licenses data from a third party, and a condition of the license is that the data remain unaltered.

  • Maybe the developer wants users to see the predicted temperature, by way of transparency—even if reality has shown it to have been far off.

In my particular case, I know the first theory does not apply, because the app in question, Weather Underground for iOS, is owned and distributed by The Weather Channel, which means it has plenty of its own data—and that data is updated every 15 minutes. As for the second theory, the most evident flaw is that the numbers aren’t labeled as (yesterday’s) predictions; for all the user knows, they were intended as real-time estimates.

Of course, I know nothing about what goes on behind the scenes with people designing weather apps, licensing weather data, or discussing what their users may expect or prefer. All I know is that this…

Today: 72°/83°
Currently: 88°

…it is self-evidently wrong. If it is now 88°F, then ipso facto, today’s high temperature is at least 88°F. This is similarly wrong:

Chance of precipitation: 30%
Current condition: Rain

No. If it’s currently raining, or if it rained this morning, then clearly the chance of rain today is 100%. I took a logic class in college. You can trust me on this.

The thing about weather predictions is that they’re just that: predictions. As conditions change, the predictions have to be updated. In most cases, the more recent a prediction is, the more accurate it is. So, if I want to find out what the weather will be like tomorrow, I’m not going to look at a prediction from last week. I don’t care what someone thought a week ago; that’s now irrelevant. I’m going to look at today’s prediction, obviously!

And yet, for some reason, people who develop weather apps (and websites) seem to imagine that this logic no longer applies after midnight (or some other arbitrary hour, which isn’t specified). What I observe is that most weather apps and websites “lock in” the predicted temperature range and precipitation for a given day at the beginning of the day, even though they were made yesterday and we have better data now. So that’s what those numbers are—yesterday’s guesses.

The question is, as a person seeking out a weather forecast online or in an app, what information do I want to know about today’s weather? Well, I certainly don’t care what anyone thought yesterday about today’s weather. I care what the professionals think now. For example:

  • How much hotter will it get today? Has the temperature peaked?

  • What are the chances it will rain this afternoon, while I’m outside (as opposed to an overall percentage for the day)?

  • Is there any action I need to take now to deal with weather changes that are likely to occur in the next few hours?

Curiously, even when weather apps and websites supply this information—as, indeed, Weather Underground does—they still hang onto yesterday’s predicted high, low, and precipitation, as though that’s in some way useful now.

Not long after I started complaining about weather apps, Adam Engst reviewed Dark Sky 5 for iOS for TidBITS. Although Dark Sky doesn’t have nearly the breadth of features in Weather Underground, it does address my main complaint directly: it always tells you what the prediction is right now, based on the very latest data. If the data changes, the app’s predictions change, exactly as I’d expect them to. So, yay for Dark Sky, which is my new favorite weather app.

But far too many other apps and websites persist with clearly invalid predictions from yesterday without bothering to consider whether that information is useful or what people really want to know. What’s sad is that it’s not a technology problem; it’s merely a failure of logic and design, both of which could be remedied easily. But when the logic and design are wrong, it sure looks like technology is failing us.
