10.6: How to boot into the 64-bit kernel
Authored by: The Eck on Sep 15, '09 01:26:14PM

How does one find out whether the machine has booted into 64 bit? I tried looking at the system profiler but couldn't find anything. Nothing showed up during the boot (like when you do a safe boot).

Thanks!

Open Activity Monitor and look for a process called kernel_task. The "kind" column will be either intel or intel (64 bit).

Also, in System Profiler - just click on the word "Software" in the Contents column.
That will tell you if you're running 64 or 32

To find out your currently running kernel, you can open up Terminal.app and type in "uname -r" or "uname -a" without the quotes, if you are in 32-bit kernel, there will be something like i386 in the output. I haven't tried 64-bit mode, but it would likely say something like x86_64 or something similar instead.

Or you can just open the System Profiler and click on the Software Category.
If it says on the second line from below:
64-bit Kernel and Extensions: Yes
You're running in 64-bit I assume.
