I have a 5 year old intel iMac using 10.7.4. I feel like it is on its last legs because I get many pinwheels with any click of mouse, and gray screens (when I reboot). I'd like to wait until Sept. for the new models. Any ideas for help in the meantime? Thanks in advance.

    Is your iMac a early white 2007 model or mid to late silver 2007 model?

    How much free space on the HD is left?

    How much RAM are you running?

    Have you tried repairing permissions using Apple's Disk Utility?

    Try using  something like OnyX to clear out a lot junk in your system?



    If your iMac has only the minimum RAM it shipped with, you may need to increase your RAM to the Max. amount your model iMac can take.

    The 2007 white iMac can take 4GBs of RAM, but is only cpapble of addressing 3 out of the 4GBs.

    Later 2007 iMac models can take a Max. of 6GBs of RAM. Installing the Max. amount of RAM will help, somewhat, with your issues, also.

    Another option is to downgrade your OS to OS X 10.6 Snow Leopard.

    You'd have to backup your data and do a clean install of OS X 10.6.

    I assume you have SL discs becuase the only way to upgrade to Lion was if you had SL installed.

    Still following my advice, SL may run much better for you given the age of your iMac.
