Could someone please tell me how to find out if my macs are 64-bit or 32-bit? Both mine are Intel Core2 Duo. 1) mac mini-2ghz-1gb ram and 2) iMac 24" 3.06ghz 4gb ram.
Thank You

Welcome to Apple Discussions!
The processors are both 64-bit - the one in the mini is a 'Merom' device, which was Intel's first 64-bit C2D processor, introduced in mid 2007. The iMac CPU is the updated version of it, the 'Penryn', which was introduced early this year.
ON EDIT: For reference, you'll see the architecture described at http://www.apple.com/macmini/intel.html (there's no directly equivalent page for the iMac)
