Gringo Vermelho Posted December 15, 2011 Share Posted December 15, 2011 No. The T2500 is a 32-bit CPU with SSE3 but no SSSE3 (note the extra S) http://www.cpu-world.../CPUs/Core_Duo/ Lion does have a 32-bit kernel but apparently the Finder itself requires a 64-bit CPU: http://netkas.org/?p=824 It's important to understand that when you see websites toting that "Lion works on 32-bit Macs!" this means Macs with 32-bit EFI firmware, but with a 64-bit CPU.
