Why am I getting these various symptoms on my iMac?
Symptoms: Keyboard keys not responsive: o,u,i,j,k,l,m
And: F1 gives me "Searching This Mac"
F2 gives me Spotlight
F3 to F8 gives me nothing. No effect on anything
F9 causes desktop windows to be separated laterally.
F10 causes desktop windows to be separated vertically.
F11 causes open windows to disappear in the top of the desktop
F12 gives the widgets screen.
I have connected a new keyboard and get the same symptoms when the new keyboard is paired. This tells me something is wrong with the iMac itself.
These symptoms appeared when the #%#%^& MacKeeper was finally eliminated from the computer.
Any suggestions on the cause?
Is this a good question?
