32- or 64-bit Kernel Startup Mode Selector... Mac OS X 10.6 Snow Leopard is 64-bit - or is it?
Well, actually Mac OS X 10.6 Snow Leopard is both 32-bit and 64-bit, and what that means for you depends on both your hardware and your settings.
I put up an accompanying website which should answer most of your questionshere.
