I'm guessing this is still valid

Open the Terminal and type the following command:

uname -a

If you’re using a 32 bit Kernel in Mac OS X:
iMac:~ user$ uname -a
Darwin iMac.local 10.0.0 Darwin Kernel Version 10.0.0: Fri Jul 31 22:47:34 PDT 2009; root:xnu-1456.1.25~1/RELEASE_I386 i386

see the i386 on the end there? That indicates it’s the 32 bit kernel

If you’re using a 64 bit Kernel in Mac OS X:
iMac:~ user$ uname -a
Darwin iMac.local 10.0.0 Darwin Kernel Version 10.0.0: Fri Jul 31 22:47:34 PDT 2009; root:xnu-1456.1.25~1/RELEASE_X86_64 x86_64

the x86_64 at the end will let you know you are using the 64 bit kernel.

My lowly 4 year old Mac mini is running Lion in 32 bit mode.
Oh, the shame!

To be honest - I feel Lion to be more sluggish in many areas compared to 10.6.8. At least on my end.

I thought the requirement for LION was a 64 bit CPU. I wonder if I got that wrong, if not, why is your Mac running a 32 bit kernel.

OH you're right - it did say that was a requirement.

I'll bet you that you're not running in 32bit mode.
