McSk8r Posted December 1, 2009 Share Posted December 1, 2009 Yes i have the sam problem. Obviously my macbook 5.1 is capable of running 64bit mode, but apple disabled it for unknown "very good reasons" ... any hacks?

lembang Posted December 23, 2009 Share Posted December 23, 2009 check the EFI, if it's 32, we dont have any choice, my mac book also late 2007,seems must wait from apple, they locked the firmware, you can try by installing any OS in 64 bit, the memory also only can be used 3GB Link to comment https://www.insanelymac.com/forum/topic/194610-macbook-pro-late-2006-core-2-duo-wanting-to-run-snow-leopard-in-64bit-mode/#findComment-1366975 Share on other sites More sharing options...
