    I just loaded OSX client onto my 2010 mini server the other day and have been having issues with low ram, all i am doing is running XBMC and only have 200mb free. I was looking around in "About this mac" to make sure that I really had 4gb or ram when i noticed that is says "64-bit Kernel and Extensions: NO".

    I double checked in the terminal and it said i386. As far as I knew there is not two separate OSX discs for 64bit and 32bit. Why would it load 32 bit?

    Mac OS X 10.6. is 64-bit, but it has two kernels,and the 64-bit kernel only loads when you set it to or on the Xserve as far as I know.
    The 32-bit kernel, loaded standardly, will not limit your overall RAM usage, as many Macs can support more than 2GB RAM nowadays, despite a 32-bit kernel.
    Take a look at the KIND column in Activity Monitor.

    For example: I have 10.6, load the 32-bit kernel and many of my 64-bit applications can take up 3GB RAM, and would even more if I had more than 4GB.

    How do you load the kernel? is that something that happens automatically?
