    About three weeks ago i was interning in china. Well, they had a Macbook that i restored to its original factory settings because it was so cluttered with erroneous files that it was easiest to just wipe it and start anew. Well i left there and now my boss is saying this

    OK I will get him to text you as soon as he gets in and he can tell you in more detail what is happening. When I have used it has suddently gone so slow that it appears the computer is not responding then very slowly it types up one letter at a time. The other problem that I have had is that the cursor suddenyl jiumps back or up and you finds yourself typing in the mdidle of the previous sentence.

    What could this possibly be? I really appreciate the help!

    PS they added new RAM while i was gone (went from 2gigs to 4) but insist that the problem started before they added the ram.

    Well, we know what it isn't... it isn't a virus

    Try a clean install of the system, or at least an Archive and Install

    Well, there's no viruses for OSX so that's not the issue. It doesn't sound like the effect of a trojan either. Likely another less-malicious problem going on.

    Then why did you use the word virus in the title? You had to know it would prompt these responses.

    Don't really have enough info to go on to troubleshoot. Have them start checking system logs in Console and if any apps have crashed they can check the crash logs. They can try creating a new user and seeing if the issues persist. etc.

    The computer slowing down could be hardware problems, maybe hdd. Or maybe software, which a reinstall would fix.

    The cursor jumping is probably when you touch the trackpad with your wrist or something (tap to click activated).

    Corrupt system
    Incorrect permissions
    Wonky RAM
    Failing HD

    The list is endless

    You can start by running Onyx, it is free, just to make sure your maintenance scripts are up to date
    You can repair permissions
    You can verify/repair the disk
    You can empty all of your caches
    You can reset the PRAM

    All of the typical things for good health of your Mac

    But I would say just go ahead and do a fresh install of OS X

    It could be a hardware issue as well? But a clean erase and install should likely do the trick.

    Trackpad jumping: Dry your hands and the trackpad.
