MacOS X 10.6 Snow Leopard is 64-bit - or is it?

Well, actually MacOS 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 questions at

http://www.ahatfullofsky.comuv.com/English/Programs/SMS/SMS.html

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 64-bit mode
• it allows you to select whether you want to start the MacOS X Kernel in 32-bit or in 64-bit mode (might not work on MacBooks, depending on how Apple implements the restriction)
• accompanying webpage explains what the whole commotion about 32-bit and 64-bit in MacOS X Snow Leopard is about

Requirements:

To check your configuration:

• Intel Mac
• MacOS X 10.4 Tiger or higher

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)

This program is free though donations are welcome. 50% of all donations go to the relief project "India's Street Kids" (for more info on the relief project see http://www.veronikawinter.de/Indien/
