I have a MacBook, which is the late 07 model. More detail specs in my signature. Will it run x64? I have 4GB memory, so I would like to take advantage of that. Also, I'm confused with this x64 stuff. Will programs be incompatible with x64 Vista? Stuff like Office, Google Chrome, etc. What about drivers? Does my OS X restore disk include the 64-bit drivers for my hardware? One last thing, can someone please explain the ins and outs of using 64-bit Windows? Are there any known problems/issues with my particular Mac? A lot of questions I know, but I occasionally need Windows and the VMs just don't cut it.
