On a 2006 MBP, there is no check box to switch on 64bit mode. There is/are 2Gb RAM and the OS is snow Leopard.


Any ideas?

Perhaps this will explain?




  • Logic Pro 9.1 and MainStage 2.1 require Mac OS X v10.6.2 or later and an Intel Core 2 Duo processor to run in 64-bit mode.


Later versions of Logic/MS need a later version of the OS, but if you don't have an Intel Core 2 Duo you are out of luck.

Note the difference...



There is a mobile "Core Duo" processor that is 32-bit only


It's the "Core 2 Duo" that is 64-bit capable.
