So, am I running LION in 64 bit?

[Jerry®]

My computer:

iMac 27in. 2.66 GHz Intel Core i5

so, I'm running LION in 64 bit mode correct? or just certain apps? I be confused. :dunno:

RAWR!

[Trouble]

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.

With great power comes great responsibility, use it wisely.

But you don't know the POWER of the Dark Side!

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.
