Is my Apple Mac running 64bit OS or 32bit OS?

Use the System Profiler to determine if you’re running a 64-bit kernel.

  • From the Apple menu, select: About this Mac.
  • Click: More Info.
  • In the Contents pane, select: Software.
  • Look in the 64-Bit column to determine if an kernel extension is 64-bit compatible.
  • If it is, the entry will be Yes.
