10.6.7 64-bit

[sakoula]

Hi,

I finished my build based on a P8P67.
I am not sure how to check whether I booted on 64-bit or 32-bit?
Do I have to worry about it? Snow Leopard is suppose to run 64-bit
apps on 64bit no matter if you boot using 32 or 64.

Is there a post describing how to boot in either modes?

Thanks!

There are a few ways to check, here's an easy one:

Go to Apple Menu > About This Mac > System Profiler

Click on the Software tab

Look for the line: "64-bit kernel and extensions: yes" or "64-bit kernel and extensions: no"

The difference between 32-bit and 64-bit boot isn't massive. But for some computationally heavy things, 64-bit is marginally faster. That said, I bet you won't notice the difference in day to day computing.

Cheers.

Go to terminal and type in the following code:

ioreg -l -p IODeviceTree | grep firmware-abi

If you got EFI64 as the reply, then you're in 64-bit.
If you got EFI32, then you're in i386
