MBP not appearing to boot into 64bit

Hey guys, I have a late 2010 MBP and am trying to boot into 64bit. I have held down the "6" and "4" keys while booting but am still coming up with "64-bit Kernel and Extensions: No" when I check in the system profiler. I had no problems booting into 64bit with my early 2008 MBP. ANy suggestions? Oh, and I am on 10.6.6.

Thanks!
 
Whats listed within Activity Monitor? Screen shot 2011-02-01 at 19.47.54.png Look for the 64bit on the right hand side.
 
It is showing 64bit listed next to several applications. However, I thought that meant those apps could run in 64bit. When I check the 64 bit kernal to see if the machine is running in 64bit, I am still seeing this...

That means the apps are actually 64-bit and running 64-bit, as that does not require the 64-bit kernel

Thank you LPZ for the link, but the article doesn't explain why I am not booting into 64bit after following those instructions. I am already aware of how to boot into 64bit. I am trying to troubleshoot why it doesn't appear to have booted into 64 bit after following Apple's instructions.

My point was to suggest that you try Method 2.

Out of curiosity, what do get from

Code: 
nvram -p

entered into Terminal?
 
The terminal command to boot 64 bit by default worked. I am trying to figure out why the "hot keys" method doesn't work.

What in particular are you looking for in the nvram -p? I got a long string of numbers and some other info.

I was wondering if
Code: 
boot-args="arch=i386"
appeared in the output. But after testing on my own system, it seems that the 6-4 keys at startup would override this in any case. So I too am perplexed as to why the 6-4 keys are not being recognized.

Are you using an Open Firmware password to disable various startup actions? (I don't think this matters either, since I doubt this restricts booting the 64-bit kernel.)

I am using a firmware password but tried to bypass it by entering the password, then holding the 6 and 4 keys when booting from the hd. Still launched in 32bit mode. Now I just want to get to the bottom of it for the sake of solving the puzzle.

Interesting. Please let us know the solution, when you find it.
