After updating to El Capitan, iTunes doesn't recognize my password. Tried to reset x 3 but still doesn't accept any password. Couldn't get into iCloud. Tried to reset in system settings iCloud but when I try to sign in it gets frozen when trying to sign in. Signed in online and reset ID and password. Now when I go to iCloud in system settings, it has old ID and won't change. I signed out completely and tried to sign in again but still shows old ID. Annoying. Keeps asking me to sign in when I'm trying to get work done. Anyone have this problem and can help?
MacBook
Pro, OS X El Capitan (10.11.5)
