Mountain lion 10.8 mac os x

With Mountain Lion, Apple is further trimming the compatibility list by being very strict about what constitutes full bit support. However, some of the Mac models that didn't make the cut this time, such as earlier versions of the Mac Pro, do have a full bit Intel processor. So, what kept them out of the running? Mountain Lion can only boot in bit mode, so any Mac that has bit EFI boot firmware won't be able to run it. If you're not sure if your Mac will make the cut or not, you can find out by following these steps:.

The second entry in the Hardware Overview list is the Model Identifier. Compare the Model Identifier with the list above. In the About This Mac window that opens, make sure the Overview tab is selected.

The above process will only work if you're running OS X Lion. If you're still running OS X Snow Leopard, you'll need to force boot into the bit kernel by restarting your Mac while holding down the 6 and 4 keys. Some Macs that aren't on the list above may still be able to run Mountain Lion, provided they can successfully boot using the bit kernel. This is possible if you've upgraded an older Mac by replacing a logic board, a graphics card , or another major component.

If your Mac can't make the jump to Mountain Lion, you may still want to upgrade to Snow Leopard or Lion, if you haven't already. If your Mac is running the latest OS it can support, you'll be able to receive software updates, and more importantly, security updates, for as long as possible.
