Apple has released the official Technical Specifications for OS X Mountain Lion which reveals that some 64-bit Macs will no longer be supported, reports Ars Technica.
Supported Models: ● iMac (Mid 2007 or newer) ● MacBook (Late 2008 Aluminum, or Early 2009 or newer) ● MacBook Pro (Mid/Late 2007 or newer) ● Xserve (Early 2009) ● MacBook Air (Late 2008 or newer) ● Mac mini (Early 2009 or newer) ● Mac Pro (Early 2008 or newer)
If you are wondering why older 64-bit Macs cannot support Mountain Lion, Ars explains:
Information included with the first Mountain Lion GM now corroborates the connection to 32-bit graphics drivers as the culprit. While Mountain Lion is compatible with any Mac capable of running a 64-bit kernel, the kernel does not support loading 32-bit kernel extensions (KEXTs). Furthermore, Macs with older EFI versions that are not 64-bit clean won't load Mountain Lion's 64-bit only kernel.

That's a shame..
My Mac Mini can run it, but my partners black Macbook from 2007 will not...
And that one has even better specs than my 2009 mini...
Hopefully they'll find a way around it....

You will still be able to run Mointain Lion in 32-bit mode on that older Mac.
