Mountain Lion Leaves More Macs Behind

With the release of each new version of OS X more Mac models get left behind, and that’s no different with the upcoming launch of OS X Mountain Lion due some time this summer. The cut off for compatible systems stretches back to 2007, but leaves machines like the original MacBook Air off the list.

The cut off for compatible Mac models includes:

  • iMac (mid 2007 or later)
  • MacBook (13-inch Aluminum, 2008), (13-inch, Early 2009 or later)
  • MacBook Pro (13-inch, Mid-2009 or later), (15-inch, 2.4/2.2 GHz), (17-inch, Late 2007 or later)
  • MacBook Air (Late 2008 or later)
  • Mac Mini (Early 2009 or later)
  • Mac Pro (Early 2008 or later)
  • Xserve (Early 2009)

That means along with the original MacBook Air, the original Mac Pro won’t be able to run Mountain Lion. Other Macs such as pre-unibody polycarbonite MacBooks and early Xserve aren’t Mountain Lion-compatible, either.

The pre-unibody MacBook from early and mid 2009, however, gets a reprieve since it include an NVIDIA GeForce 9400M graphics card which will support Mountain Lion.

Dropping support for older Macs isn’t anything new, but it still stings a little for users that aren’t ready to upgrade from their trusty old iMacs and MacBooks yet.
