Click THIS for more info about your processor.


or read below:


Basically any Mac released after late 2006 is 64-bit. If you’re unsure whether or not your Mac is 64 bit or not, the easiest way to check is to find out what kind of processor your Mac has in it, and the easiest way to do that is to pull down the Apple menu and click ‘About this Mac’ and then look at what is listed next to “Processor”

Intel Core Solo - 32 bit
Intel Core Duo - 32 bit
Intel Core 2 Duo – 64 bit
Intel Quad-Core Xeon – 64 bit
Intel Core i5 – 64 bit
Intel Core i7 – 64 bit
