    Hi Everyone,

    I have a 1st generation MacBook and was wondering if it was 64-Bit or 32-Bit. I'm upgrading to Leopard tomorrow and would just like to know for my own interest whether or not I will be running it on a 32-bit or a 64-bit machine.

    Thanks!
    Brian

    1G were 32 bit I don't think that there will be that much of a difference though.

    If you are using a First Gen MacBook, then it is a Core Duo and therefore 32bit.
