    Help.. Im having a lot of trouble with mi iMac running extremely slow from boot up with hardly any applications running. I have 12GB of RAM installed and would expect a bit more sped in performance. Activity monitor shows 9.5GB of wired RAM leaving little free and inactive RAM to use and I have absolutely no Idea what wired RAM is.

    Anyone have any idea??

    Thanks for any help..

    A better explanation of wired memory (From the Developer Library):

    All that being said, the amount of wired memory that you are seeing is not normal. I would recommend booting in safe-mode (hold shift during startup), disable Time Machine completely, and disable local backups with the command
    sudo tmutil disablelocal
    in a terminal window.

    Just a quick question about installing memory - I have 2 2G and 2 4GB... they are showing up opposite diagonally in the About This Mac Memory. Is that OK? It says all memory slots are currently in use.

    You should have an application running with a memory leak. Activity Monitor will help you to find the one consuming that memory.
