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.

What does this app do?

  • it shows whether you have a 32-bit or a 64-bit processor
  • it shows whether you have a 32-bit or a 64-bit EFI
  • it shows whether the MacOS X Kernel is set to boot in 32-bit or in more...

What's New

Version 1.6:

  • NEW: updated info on new Mac models
  • NEW: added bug reporter (haven't heard of any bugs but since I added it to all my apps …)

Requirements

To check your configuration:
  • Intel Mac
  • Mac OS X 10.4 Tiger or later
To set the kernel\'s startup mode:
  • Intel Mac
  • MacOS X 10.6 Snow Leopard or higher
  • Admin rights (as a system file needs changing)
