Very annoying - new iMac with Mountain Lion.


I do much typing on internet via Wordpress, etc., but also happens when typing in programs. I'm typing along when interrupted by a soft drum bear and no more capture of type. The screen shows I have moved away from the open window and must click on it again to resume work. At first I thought it was a response to space bar, but now I'm not sure. Even typing these few lines, work was interrpted 4-5 times. I'm a writer - I can't work this way. Any one know what is happening? I do use a wireless keyboard.


Thanks - Carol

iMac (21.5-inch Mid 2011), OS X Mountain Lion (10.8.2)

    That sounds very annoying. It would be good if you had a wired USB keyboard and mouse to use to determine if the problem is your wireless keyboard and mouse. It is as if the wireless mouse is malfunctioning.


    I'm old school and prefer wired, but here is an article, below, to check out, if you don't have a wired keyboard to try. Even one from a windows PC would do for a test.

    I'm typing along when interrupted by a soft drum bear


    Put the bear outside to play the drum. If that doesn't work, proceed as follows.


    Please read this whole message before doing anything.


    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.


    Step 1


    The purpose of this step is to determine whether the problem is localized to your user account.


    Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”


    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.


    Test while logged in as Guest. Same problem?


    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.


    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.


    Step 2


    The purpose of this step 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:


    • Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    • When you see the gray Apple logo, release the shift key.
    • If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.


    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.


    *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.


    Test while in safe mode. Same problem?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    roam - I do have a wired keyboard, and hooked it up. Some improvement, but still issues. Also develped a flicker on my screen. have a genius bar appointment next week, but in the meantime will run through Linc's test - thank you.
