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One of the occupational hazards of writing about technology is that books go out of date as hardware and software changes.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:
