System Preference on iCloud and Account won't let me update my provider accounts. Even adding an email accounts on mail app won't work. Any updates I needed to work my mail accounts or a server that needs to be install
MacBook Pro with Retina display
What happens when you try to add the accounts?
Might be a corrupt .plist.
Do a backup, preferably 2 backups on 2 separate drives.
Quit the application.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart the computer, open the application, and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
