Is there a way to increase speed of M.Lion?


Defragment Files?

    How much RAM do you have installed? More RAM is always good if your machine can support it. How much hard drive space do you have free?


    The system defragments many files automatically - generally there's no additional need or benefit in doing so.

    Please be more specific? ML is extremely fast however your problem may be that your system does not have adequate RAM. ML minimum specifications are 2GB of RAM, however most users on this forum recommend 4GB or more. I'd recommend reading


    Using Activity Monitor to read System Memory and determine how much RAM is being used

    Thanks Matt, have 4GB RAM and ca 250MG is free. It looks that must double this RAM.

    Seasons Greetings

    250MB is almost nothing for free RAM. I'd recommend installing additional RAM if your system has the ability. Exactly what year and model iMac do you have. It may be about to accomodate up to 32GB of RAM if it is a 2010, 2011 or 2012 model.

    Thanks for the tip

    Have space for 4 more GB. Is it a "DIY" or must go to Apple service?

    If you could answer my other post I could likely show you your better/cheaper options than having it done.
