After I had to force quit System Preferences I also restarted my iMac. Now, when I open Finder, ALL the listing of "My Documents", "Applications" have disappeared! The docs are there, for whe I open Excel, or Word, I can access the documents.
And "Desktop" tab in System Preferences still stops while "Loading Images"! I have to Force Quit again...
When I click the apple icon and then "About This Mac" nothing happens... In the past I could get the info
When I stick an external Scan stick: nothing shown on desktop as before
When I switched from one user to the other (there are only two) , the screen turned to the new user with the password prompt. Now after a long wait, only a blue screen and after a while the password prompt.
Whan has happened here? What can be done to restore
I might have, some on iPad. what kind of third party apps?
And it gets worse:
When I open iPhoto, the following notice appears: "Caution The iPhoto Library is locked, on a locked disk, or you do not have permission to make changes to it."
When I connect my iPad, iTunes does not open and I cannot start iTunes manually
As I cannot see the application in the Finder, I can only access those few on the dock.
I am at my wits end...
