    Hi,
    Today, I received a Mac Mini, which I love - it is my first Mac.
    After going to 'Software Update' and installing the latest updates (for I'm not sure what) I have encountered an incredibly annoying bug!
    The cursor doesn't move smoothly, it sort of leaps/jumps around the screen.
    I tried a different mouse, however it still occurred, so it's nothing to do with my mouse!
    Please, please help as it is ruining my first Mac experience!
    Cheers

    What surface is the mouse on?

    What is your monitor? And it's resolution?

    I had the same problem on my old LCD, an HP 2009m @ 1600x900. I then upgraded to a bigger screen (1920x1080) and the problem went away. Same for my new thunderbolt display.

    One strange thing I noticed, with my 2009m, if I used any non widescreen resolution, the problem went away. Never understood why...

    Consuming your RAM

    Try checking the Activity Monitor, definitely and most likely there are unfinished thing going on that is consuming your RAM, this happens to me the cursor gets jumpy when there is no RAM left to juice out in my machine.

    I upgraded to 8GB of RAM - I somehow doubt this could be the case. Thanks anyway.

    If you did in fact have some kind of weird memory leak issue, the issue would be coupled with noticeable and possibly audible hard drive activity. I've seen tons of cursor bugs. I'm not sure what exactly is causing this though. There's no pattern of any kind?

    hate to bring up an old thread but I have experienced this issue while downloading things on my 2011 Mini. It only happens while using the Magic Trackpad - any wired mouse works fine.

    So Im wondering if Bluetooth is interfering with Wifi...
