Yes, it’s nearly time for another release of OS X. The new version, Mountain Lion, is scheduled to be released sometime this month (though the date has not yet been revealed). Apple has now released the official list of hardware that will be supported by OS X Mountain Lion.

The good news is that most recent Mac hardware is included – but the exclusion of a few recent models may cause consumers to feel slighted. Here is Apple’s bullet-point list of models which will be supported:

  • 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)

The safest users are those who own iMacs or the MacBook Pro as models that are up to nearly five years old will be supported. The MacBook Air and Mac Pro are also in relatively good shape, though it’s worth noting that the first version of the MacBook Air is now out of Apple’s good graces.

MacBook and Mac Mini owners, on the other hand, may not be happy with this announcement. Some models of these products that are only a hair beyond three years old will be left looking at Mountain Lion’s behind. This includes all of the non-unibody plastic MacBooks.

Why have those models been dropped? Apparently it has to do with the 64-bit nature of Mountain Lion. Some of the Macs that will not be supported have 64-bit CPUs but also have GPUs with 32-bit graphics drivers. Mountain Lion does not support 32-bit kernel extensions and Apple apparently does not want to invest time and money into developing new 64-bit drivers for these older machines. This means waving goodbye to some hardware that isn’t particularly old.


How do you feel about this? Is your Mac able to run Mountain Lion?
