I just changed the password of my Apple ID.
When I started using my Mac, several minutes later, the system preferences asked me to enter my password to continue using iCloud. after entering my new password, it hanged. Restarting the mac did not even work, I had to hard shut down the machine.
After the machine is rebooted, it asks me once again to enter the password of Apple ID...
Could anyone help?
