My iCloud doesn't display the right Apple ID. I can't change it or log out of iCloud, because System Preferences just hangs frozen, so I have to force quit which doesn't save any changes I've tried to make to the ID. Consequently my iPhone doesn't backup.
My iCloud doesn't display my correct right Apple ID, and my iPhone won't let me type that ID in as it says it's already in use. Also iCloud won't let me change the ID listed there, or even log out of iCloud closing the account, because every time I try System Preferences just hangs frozen, so I have to force quit which doesn't save any changes I've tried to make to the ID, password or account details. Consequently my iPhone doesn't backup well at all. The whole iMac slows down massively every time I try to address this issue, and my iMac doesn't recognise the iPhone in Finder, and tells me the Wifi connection is not supported..!!??
Can anyone help?
iMac, Mac OS X (10.7.3)
