    I have been having problems with my mouse and my browsing lately. My browsing lags meaning that scrolling down is often slow. Also when I want to change tabs on my browser from one page to another, it takes time for it to change. With that, my mouse has now began to stop working though I can move it around the screen, it doesn't allow me to do anything, like clicking, or even shutting down. I am sure it's a memory issue. In the PC world, we defrag or remove all temp files. How do I do that in a Mac?
    Thanks for your help.

    This is a Mac--not Windows--and your diagnosis contradicts your solutions. It could be that you don't have enough memory (RAM), but clearing up hard drive space won't fix that. It could also be that you have a bad hard drive, amongst other things. If your machine is under warranty, you should most definitely back up your data and bring it in.

    "diagnosis contradicts your solutions" my diagnosis? I have no solution. I am trying to say that my iMac is running slow and it tends crash. I say that in a PC i would do this but in a Mac, what do I do? if you have a solution, please reply.
    Thank You!

    Hi OP. It could be any number of things that are causing your problem, so I should try some of the problem solving solutions in this link,, before taking it back to the supplier.

    What model iMac do you have, how much RAM and how much free space on your hard drive?

    Thanks...I'll try that. The facts are that in a PC, I would clear out all temp files every so often, in a Mac, not sure how to, to see if that helps. I'm also wondering if Firefox and having downloaded the latest version has anything to do with that as it's been since I downloaded the latest version is when I started to notice OR it could be a coincidence.

    Hi THEROC,
    please post the model of your iMac + size of your HD and free space on it.
    If you want to clean your 'temp. files' (and more) get one of the utilities I'll post, altho this isn't as critical on Mac like on a PC.
    Also you don't have to defrag a HD since your OS X is doing that every day (usually set to '3 A.M.' automatically {by OS}). For that to happen you have to leave your iMac on (if you're not OK with leaving your computer "on" all the time than leave it 'on' once a week overnight).

    Hey Thanks
    HD is 235Gb, available 3.5Gb, processor 2.4 Mem 4 Gb 800MHz DDR2 SDRAM
    The problem is mainly browsing, the cursor stops working at times and I have to force a reboot, scrolling is a problem at other times and even typing this is very slow. The rest is fine I assume though I don't use it much at the moment. I might try and using Safari which I am not much of a fan but just to try and see if that performs better.

    Chrome or Safari will perform better - Firefox is bloated and slow, particularly on OS X, compared to them.

    Hi again,
    your HD free space is way TOO LOW.
    You meed to leave 10 ~ 20% of your HD free (at least 10%).
    And you have roughly 1%...
    No OS (Mac and/or win) will work properly with that kind of free space.
    You should delete or move (to external HD) items not essential to your running of your iMac.
    If you're not sure what to move or dump - let us know...
