1. system prefs > account > sign out
2. Try to Sign in with a fake acc - apple/123456 - whatever. Will fail
3. Sign in again.
4. Try idisk in finder. if it works... great if not goto 5
5. spotlight > search for an open keychain access
5. Top menu > KEYCHAIN ACCESS > Keychain first aid.
6. Enter your user and pass > checkbox verify. Start.
7. If verification failed > checkbox to Repair > start
8. Verify
9. Reboot.
