Does your Mac make the cut for Mountain Lion? Not all of them will, although if you’re already running OS X Lion, chances are good that you’ll be able to upgrade. Still, you will want to check. The following hardware models will support Mountain Lion:
- iMac (Mid 2007 or Newer)
- MacBook (Late 2008 Aluminum, or Early 2009 or Newer)
- MacBook Pro (Mid/Late 2007 or Newer)
- MacBook Air (Late 2008 or Newer)
- Mac mini (Early 2009 or Newer)
- Mac Pro (Early 2008 or Newer)
You can upgrade from OS X Snow Leopard (OS X 10.6.8) as well as Lion (OS X 10.7). You can purchase Mountain Lion from the Mac App Store and install it to your computer. I do highly recommend backing up everything before proceeding, everything should be there, but why take the chance if something goes wrong. And you have a month or more to look at the applications you use and depend on to contact the manufactures of the software and make sure it is compatible before your upgrade.
