[QUOTE="Mike G R, post: 1724160, member: 364042"] How do I confirm that my MacPro3,1 (early 2008) is using a 64-bit kernel? Here's what I know: - Activity Monitor states in Kernel task is 64. - Preference Panes in 'About this Mac' state: 64-bit (intel): Yes - I used "sudo systemsetup -setkernelbootarchitecture x86 64" Apple says that 2008 MacPro shipped with 64bit ability but that it does not boot by default into 64bit.
