Here’s an easy way to determine whether or not your Mac is 64 bit capable. Open Terminal.app, which is located in /Applications/Utilities and type in:

sysctl hw | grep 64bit

If your machine is 64 bit capable, the result will be

hw.cpu64bit_capable: 1

If your machine is not 64 bit capable, the result will be

hw.cpu64bit_capable: 0
