    "Cleaner" softwares actually are overkill and frequently cause more problems than they are worth.   The worst offender is MacKeeper which should be removed.


    If you have any such software other than MacKeeper, ask the vendor in question how to remove it.


    The only utility a Mac needs is a backup utility.


    General rule of thumb, keep your hard drive at least 15% free, and only install software known to work with the revision of the operating system in question.   Unless you need to run Windows in virtualization, that's all you need to know.  If you have some other issues taking place, state what they are.

    1. Try this

    Go to your Finder "Go" menu hold the option key to choose "Library". Then go to Preferences/com.apple.finder.plist and delete that file. Then log out and back in or restart. Don't worry the plist will rebuild itself. Now test.


    2. None. Absolutely none.

    I did what u asked me to and I think my Mac is gone for toss now.?

    The keyboard volume button is not working. I guess the entire first row is not working.????

    They keyboard system preferences may have gone crazy due to tossing that plist, and the function keys will only work if you hit FN together with them.    Go to Apple menu -> System Preferences -> Keyboard and Mouse and change how the FN key option is activated through the checkbox there.

    Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.


    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.


    Isolating an issue by using another user account


    If the problem is still there, try booting into the Safe Mode.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.

    Thanks Brody. That helped. Kinda feeling better now.

    Would like to know if i can upgrade to the new OS mavericks wen it is available. Will there be any issue with the system.?? Or will it get slower.???

    You'll be able to upgrade to Mavericks - which has some wonderful advanced technologies for notebook computers according to the Apple website -> http://www.apple.com/osx/preview/.

    Just FYI for anyone else who lands here from Google like I did.  I ran into this issue on Mavericks and, for me, it turned out to be because I had moved the System Information application out of the "Utilities" folder and into a folder I named "System".  Once I moved it back to "Utilities" it began working again.


    While researching the issue I came across this site where Cody posted his solution:

    "caused by renaming the Applications/Utilities folder. The 'System Information.app' must be located at Applications/Utilities."

    Thanks for sharing. Sometimes we forget that users move things to make it easier for them to find.

  • a brody Level 9 (65,765 points)

    This is where everyone needs to remember, the Apple applications are not to be moved, and the folders not to be renamed.  You may map them to an external hard drive for space, but generally speaking, only rename or move items you added yourself
