    hi, i installed snow leopard. i have a macbook 4.1 early 2008 and i wanna know if it is working at 64 bit. i went into system profiler->System Software Overview->64-bit Kernel and Extensions: No. does it mean the os is not working at 64 bit? if it isnt, how can i enable it to do so?

    Your apps are 64-bit but kernel isn't. Don't change it to 64-bit, you'll only get headache

    someone did quote a source in another forum (macbook air??) saying that there will be a firmware update to enable more macs with 64-bit capable processors to run the 64-bit kernel. Unfortunately I can't remember if it was a rumour or fact. (useless i know)

    However i'm with hellhammer, although it is possible to force a the 64-bit kernel, i wouldn't. From what i have read you won't see any benefits and are more likely to have problems.

    Edit: Found it: http://forums.macrumors.com/showthread.php?t=774514 (See Post no.13.) Not quite quoted as i thought and still not sure if fact or rumour, lol

    Apple is currently taking the stance that the only Mac that should boot with a 64-bit Kernel is the Xserve. Not even the Mac Pro or MacBook Pro where more users would benefit from a 64-bit Kernel get it enabled by default.

    On the MacBook line, Apple intentionally disables Snow Leopard booting with a 64-bit Kernel. Apple's view has always been that consumer level devices do not support 64-bit fully (although this is an artificial limitation).

    Apple intentionally restricts its drivers for Boot Camp so that they will not install on 64-bit Windows (without some tweaking) if you own a MacBook or similar desktop Mac.

    Whether you should go 64-bit or not (and that's been hotly debated), I think it is now unlikely that Apple will support the 64-bit Kernel on your MacBook or my MacBook.

    It's possible that 10.7 will only work on 64-bit Intel Macs (and as such they'd need to enable the 64-bit Kernel on all of them), but I have no idea when 10.7 will be out or if it will actually run on these computers.

    2 year cycle...

    if you follow the cycle, i would think that approximatly every 2 years on average there is a new OS for apple! Leopard 2007, Snow Leopard, 2009... leopard was late it was supposed to come out in april of 2007 or so... i would venture to guess 10.7 will be in hands approximatly this time in 2 years or so. maybe 2 and a half three years at most.
