Force restart Apple Vision Pro
If Apple Vision Pro isn’t responding, and you can’t turn it off, try forcing it to restart.
Press and hold the top button and the Digital Crown until the displays turn black (keep holding even when the Force Quit Applications window and the power slider appear). You can take off Apple Vision Pro while it restarts.
While Apple Vision Pro restarts, the Apple logo appears on the front display. If you can’t see the Apple logo, you may need to press and hold the top button for a few seconds until it appears.
