If you rushed off to the Mac App Store to download OS X Mountain Lion as soon as it was released this morning, then I hope you like it. Because once you’ve handed over your cash, there’s no going back. Apple has now pulled OS X Lion from the Mac App Store, and once you’ve purchased Mountain Lion, it will be removed from your “Purchased” list.
What this basically means is, unless you have a copy of OS X Lion stored locally, you now have nothing to show for the $30 you paid for it 12 months ago. That’s not too much of an issue if you like Mountain Lion, but if you don’t, or if some of your apps don’t yet work, then it’s going to be difficult to go back.
With that said, be sure you really want Mountain Lion before you purchase it, and use Roaring Apps to check whether your favorite applications are compatible before installing.
Apple’s decision to pull Lion does make a lot of sense. After all, you can upgrade to Mountain Lion directly from Snow Leopard, and keeping Lion in the Mac App Store alongside its success will only create confusion among users.
