Snow Leopard 64-bit kernel mode: secret disclosed

Wednesday, February 17th, 2010

for the people who knows what a Command Line Interface is this is the command to startup automatically yourĀ Intel Core 2 Duo Mac (with EFI64 boot loader) in 64-bit mode

sudo systemsetup -setkernelbootarchitecture x86_64

or return to 32-bit mode

sudo systemsetup -setkernelbootarchitecture i386

Good for Mac Mini servers (EFI64 only) where a keyboards not connected and it’s not possible to press the ‘6’ and ‘4’ strokes at startup time.
