    I have a 1st gen Macbook, (2GHz core duo, not core 2 duo) and snow leopard works perfectly. It runs using the 32bit kernel. My macbook pro (core 2.4GHz core 2 duo) uses the 64bit kernel.
    Snow Leopard includes both kernels.

  • It is both. If your Mac is able to boot in 64 bit, it will do so or you may need to toggle it.

    Be aware that not all Macs can boot the 64 bit kernel and that not all applications will take advantage of 64 bit operations.

    MacBooks and MacMini's are known not be able to boot the 64 bit kernel.
