Question: high sierra update loses bluetooth

My Dad has just updated his IMac to High Sierra. He got the progress bar and left it for over 35 mins to upgrade. When he returned to the iMac there was no response. He forced a reboot by holding down the power key for several seconds. He tried to enter his password but got no response from the keyboard. Force rebooted again. Then a message popped up asking why he wanted to change his password - one option was because the keyboard wasn't responding (which I thought was strange??). But he can't get his wireless keyboard or mouse to work. Any ideas?

If he starts up as described and still has no keyboard or mouse visible, then there is likely a hardware failure. If so: make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple.
