With Mountain Lion reaching gold master status, it means Apple is nearly ready to ship OS X Mountain Lion to customers like you. But in order to use Mountain Lion, you have to have a certain type of Mac. Apple is cutting off older Macs from using Mountain Lion by making them ineligible for the upgrade.


According to Apple, your Mac has to be newer than one of the following models to use Mountain Lion. Most of the cutoff points are set at 5-year-old computers, which is reasonablish, but the poor Mac Mini has a low kill date of 3 years. If that tiny Mac of yours is older than three years, you're not getting Mountain Lion. Here's the list of computers eligible:

  • 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)
  • Xserve (Early 2009)

Apple didn't specify why computers older than these can't get Mountain Lion but Ars Technica speculates that its because of a graphics issue with certain Apple 64-bit computers. Some of Apple's older machines have 32-bit graphic drivers and Mountain Lion won't load them, which make those graying machines incompatible with Mountain Lion. Time to get a new computer!

I hope my work computer makes that list.

- Mac Pro, 2.66 GHz Quad-Core.

I started at my current job in March of 08 and they got me my computer new at the time...

Lord knows they're tight with their pennies. It took all 3 of the years I've been working here to convince them to upgrade my Adobe Creative Suite (I'm lead graphic designer). Lord knows how much of a struggle it'll be to get a hardware upgrade out of them if I need it. :/ (I'm sure they'll say I don't need to upgrade my OS right away, and while that's true, I really don't like falling behind on it)
