    Simple question maybe but I'm not sure about it.

    I was reading that snow leopard is going to push 64bit... Will my mac be able to handle it and whats even the big difference?

    More so, is it worth upgrading to 64bit leopard right now? Again, whats the difference?

    Thanks for the help,

    All Core 2 Macs will run Snow Leopard.

    Core 2 does not mean Core Duo.

    All intel Macs have supported 64-bit. Snow Leopard will the first 64-bit Mac OS though.

    Tiger was partially 64 bits. Leopard is also partially 64, with more 64-bit parts. Snow Leopard is the first "full" 64 bit Mac OS.

    Now there is only one version of Leopard - Apple doesn't do the Windows thing where there are 64-bit and 32-bit versions of OS's

    Yes - your machine will be able to handle 64 bit. Leopard supported 64 bit applications, but the kernel itself was 32 bit. Snow Leopard will be running on a 64 bit kernel.

    Not true. The first Intel Macs were Core Duo or Core Solo, a 32-bit processor.

    Intel Core Duo = 32-bit
    Intel Core 2 Duo = 64-bit

    Leopard is a 32-bit kernel w/ support for 64-bit. It is also PAE enabled, so it has the ability to mimic as 36-bit for memory allowances of up to 64GB.
