Latest model 27" iMac i5

Mac 10.7.3



Safari unexpectedly quit and I lost my gestures. I was running Airport Utility, trying to configure my time capsule. Figured a restart would resolve the issue.


Upon boot, the cursor acts normal at the login screen. It works as should using the guest account. However, when I log in, the cursor flys to the top left and finder makes an angry buzzing sound. Cursor keeps flying back on me.


Here's a video clip I took via iPhone: http://www.youtube.com/watch?v=YhG24Q7AoIY


Please help me!





iMac, Mac OS X (10.7.3)

    Try smc and pram reset.


    If that doesn't "shake it free" see if you can boot from your recovery partition and run Disk Utility to try to repair/verify your drive(s).


    Are you sure that sound you hear is coming from your speakers or is that a weird hard drive problem with the heads going berserk?

    I can mute it with the keyboard. It will also start if I can quickly open another app from the dock. It will beep again if I go back to the finder.


    I reset the pram. No change.

    Repaired permissions via disk utility. It yielded a few repairs. No change on reboot.


    Any more ideas?

    Please read this whole message before doing anything.


    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.


    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:


    • Be sure your Mac is shut down.
    • Press the power button.
    • Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    • Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).


    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.


    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Test while in safe mode. Same problem(s)?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    I restarted holding the shift button as described. Issue declared temporally resolved. Restarted Mac without holding shift. Issue declared resolved.


    Thank you very much. I wonder what bug caused this.?




    Thanks again. :)
