Even though Snowie runns in 32 bit its not bad to be future proof According to Apple all you have to do is look in your "About This Mac" from your Apple () menu, and seeing if the processor is a Intel Core 2 Duo or higher But come on apple we want a more Geekier way of checking, Well... They have Muhahaha So... The other way to check to see if your Mac is 64 bit compatible by using the command line. You will need to Launch terminal which is located in '/Applications/Utilities' and type 'sysctl hw |grep 64bit' Note: There is not a space after the vertical line. After pressing enter you should see hw.cpu64bit_capable: # At the end of the string that is printed out there will be one of 2 numbers 0 which means the cpu is not 64 bit and 1 means it is 64 bit... YAY As I was doing more research on the subject at had I found a cool app Called Startup Mode Selector ( the link is in the show notes. What this neat little app does it shows whether you have a 32-bit or a 64-bit processor, 32-bit or a 64-bit EFI, MacOS X Kernel is set to boot in 32-bit or in 64-bit mode, MacOS X Kernel is running in 32-bit or in 64-bit mode, If your Mac officially supports booting a 64-bit kernel, it allows you to select whether you want to start the MacOS X Kernel in 32-bit or in 64-bit mode, and more If you are running Leopard this app wont work for you, Snowie users only.. Sorry I didn't develop this app. And that going to do it for this episode of Mac Tip Podcast I hope you enjoyed it The music for this podcast, preformed by Professor Kliq ( and our announcer was Josh Philpott If you have any comments, questions or tips?
