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.
