Check if your Mac is 64 bit

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

    This only appears to indicate that your Mac can run 64-bit applications. It does not indicate whether you can run Snow Leopard’s 64-bit kernel.

    Thanks for the heads up, I wasn’t aware of this.
