I’m getting a question asking whether I’m running a 32 or 64 bit Snow Leopard? Here comes the solution.
- Go to the Apple menu, click “About This Mac”
- Click “More Info” to learn more about your mac
- The System Profiler app is execute
- On the sidebar, click “Software”
- You will see 64-bit Kernel and Extensions, either it is Yes (you are running 64bit) or No (you are not).
