    I have been reading user's posts about running SL in 32 or 64 bit mode, a decision that is set to 32-Bit as the default.

    Where during the installation process does do you change this?

    I just want to Install the 64 Bit Kernel or at least, only use the 64 Bit Kernel if possible.

    Thanks

    To have kernel 64-bit, you have to hold down 6 + 4 while booting the computer.

    Well that sounds like a scarcastic joke, im sure its accurate. Leave it to :apple:

    So Is this a 1 time thing? or do I have to hold 6+4 every reboot to enable 64-Bit mode?

    You do know that if have drivers that are 32bit only they'll not load when going into 64bit. You may lose access to your scanner, or printer, or some other peripheral.

    At this point in time, there's really no reason to force the kernel to boot into 64bit mode - other then getting a nerdon

    I checked system profiler after installing SL and noticed that the iLife '09 apps from my MBP bundle disk are NOT 64 bit... I wonder when they will switch them over... iLife '10, perhaps??
