How to Check if your Mac Support 64 bit Kernel Booting

Earlier today we posted (check here) details of minimum system requirements for Mac OS X Mountain Lion. As you know, Mountain Lion requires your hardware to boot into OS X 64-bit kernel, so following are the instructions to check if your Mac support 64 bit kernel booting or not. 

You can check for 64 bit kernel boot suport by typing “uname -a” at the command line, launch the Terminal to do this. The uname -a command will return something like this:

root:xnu-1699.24.8~1/RELEASE_X86_64 x86_64

Look for “x86_64” to verify that a Mac is booting into a 64 bit kernel, That’s it.
