    Hi guys. I require my late 2009 MacBook to boot Snow Leopard in 64 bit by default, without having to hold down "6" and "4" keys, as I am using Adobe Premiere Pro CS5 which requires 64 Bit Mac OS X for better performance.

    Any ideas how I set it to boot 64 by default?.

    TY

    Nop that will not work. You need to patch boot.efi, even if you press 6 and 4 the macbook wont boot in 64bits mode. If you want the patched boot.efi file it's here Boot_efi_mod

    It worked with my 2009 17" MBP without hiccups.

    But that's on an MacBook Pro. Apple for an unknown reason blocks macbooks from booting in 64bit mode. Look here Unlocking 64-bit efi Macbooks for 64-bit kernel. bear in mind that the boot.efi file on netkas website doesn't work with the latest macbooks

    I find that very hard to believe. Could you post any link to where you got this information from? I hope you realise that Snow Leopard is a 64 bit operating system, no matter whether the kernel is 32 bit or 64 bit?

    No problems:cool: I still don't understand why uncle Steve doesn't want macbooks to run in 64bit mode, oh well it's Steve:D

    Because they want you to buy a MBP instead, or upgrade.
