I have just upgrade to snow leopard .
It tells me now that now running version 10.6.1
But if I give in terminal the command uname - a it says i386 that means that it is 32 bits version
And everybody told me that snow leopard is 64 bits.
Or is the branding in the kernel ?
Can anybody helps me out ?

you need to press and hold the 6 and the 4 keys when booting OS X

By default, the 32 bit version of OS X is loaded

What Mac do you have? from what I had read on various websites, if you have a Mac that has a 32bit EFI, it will block you from loading the 64bit kernel, and that 64bit kernel couldn't be loaded on any non-pro Macbook.

It's been a long day and I don't have the links in front of me, but a quick search pulled up this here:

Startup Mode Selector

if you skip over the program information itself to further down the page, there is some description of the limitations put in place by Apple.

If you have the 2006 Mac Pro (which is what it *sounds* like you have (2xdual core xeon) then you have a 32bit efi from what I understand - otherwise - no 64bit kernel

Trust me, even if you could boot into a 64-bit kernel, you don't want it. Many programs have kexts that are compiled for a 32-bit kernel and won't work with a 64-bit kernel. Unless you are doing something that explicitly needs 64-bit support, avoid it for now.

And yes, most of your applications are running as 64-bit applications. Just open up Activity Monitor and look at the "Kind" column. See link in sig for more info.

It seems that if you know the EFI of you're system is enough to determine if it can ran 64 bits ,ore not
My MAC has a EFI32 so it is the first Intel Xeon dual core , that only can run 32 bits
If somebody needs the command it is ioreg -l -p IODeviceTree | grep firmware-abi
