Im not sure.. its pretty new i got it after the Februrary Update of this year, its the 2.4 ghz intel core 2 duo version.. is it a 32 bit or 64?
Got a tip for us?

hi, i bought mine in early 2007 i think.. its a macbook 2.2ghz leopard
i tried to do a parallel desktop with linux ubuntu 8, it says i cant do it because it requires a kernel x86 - 64bit cpu and my macbook is i686...
i tried open suse 10 it says it cant run coz my macbook is 32 bit..?
please somebody explain to me whats all this..🙁
thanks😀

Because the virtual machine created by Parallels was 32-bit; has nothing to do with your computer's 32/64-ness.
Is there any use booting up into 64 bit mode? It takes ages, but does it actually make it faster? Is there a way to tell if your in 64 bit more right now?
Just booted up into 64 bit, I know how to tell if your in it. But if anything, it's slower?

I've got a Core 2 duo macbook and mine checks out as " 64-bit Kernel and Extensions: No".. So not all Core 2 Duo machines are at 64 bit apparently...

Indeed they are, they just don't boot the 64-bit kernel. There really isn't a whole lot of point to it, especially on a laptop. You still have a 64-bit processor
As long as I have a Core 2 Duo, does it matter that i'm loaded in "64-bit Kernel and Extensions: No", if I want to run boot camp with windows 7, can I install 64 bit or do I need to run 32 bit? Or does it matter?

Apple confirms above - all Core 2 Duos are 64-bit processors.

There are three things at work here:
1. Is the processor 64-bit? AKA: Is the processor capable of running 64-bit code. If you have any Intel-based system *OTHER* than the very earliest 2006 systems with a "Core Duo" (or Core Solo, which was an option on the Mac Mini,) then the processor is 64-bit. *EVERY* "Core 2 Duo", *EVERY* Xeon, and *EVERY* "Core iSomething" is 64-bit.
2. Is the Kernel 64-bit? This is significantly less important than you think. By default, only the Xserve would boot into the 64-bit kernel. Really, the only thing this affects is if the core of the OS can access more than 4 GB of memory for its own internal use. This has no bearing on applications running 64-bit code, or using more than 4 GB of RAM.
3. Is the application 64-bit? This is what matters to most users. If #1 is "Yes", and the application is capable of 64-bit operation, then you're good. For the most part, the only gain you get by running in 64-bit mode is that individual applications can access more than 4 GB of RAM. Standard consumer applications have effectively no reason to do so, only higher-end applications often need the use of that much memory. (Right now, any way.) Also, because of the way 64-bit mode works on Intel (and AMD) processors, *ALL* operations see a very slight performance increase running in 64-bit mode vs. 32-bit mode - if the application is capable of 64-bit mode. In general, this performance boost is under 10%, though, so for most uses, it's barely noticeable.
