WHen I go to the App store or to apps that I have already loaded onto my iMac, it will ask for my password, which i provide. THe response is either "unknown error has occured" or invalid user/pw. So after a few tries i will go to the "forgot password" and change the password successfully. When I go back to the apps store I get the same messages.

Another error msg is the app was loaded by another computer, which didn't occur either.

I did check for viruses and malware, but it came back clean.


Any suggestions??




iMac, Mac OS X (10.6.8)

    May be a '.plist" problem.


    Close all applications.


    In Finder hold the option key down click the "Go" menu in the menu bar.


    Select "Library" from the dropdown.


    Librarry > Preferences

    Look for these two files.





    Delete them. Restart the computer.

    Try App store.
