Now that OS X 10.8 Mountain Lion has been released, it’s time to look into all that’s required to upgrade. We touched on this a little bit late last week, but if you’re going to update, now’s the time to really double-check to make sure you’ve got everything ready for a switchover.

Fortunately, we’re here to help, with our Mountain Lion Compatibility and Transition Guide. There, you’ll find an extensive list of hardware and software that’s been tested (or will be tested shortly) with Mountain Lion for compatibility.

Once you’ve made sure your computer can run 10.8 and everything else in your system will work with it, you can then back up your system to an external drive (not necessary, but highly recommended – just in case), sign in to the Mac App Store (10.6.8 or later required), download the installer and update away!

Early adopters… let us know how it goes in the comments.
