Apple Vision Pro
Most computing devices that see active use from users can do with the occasional powering down. Restarting an iPhone or a Mac can dust out the metaphorical digital cobwebs and avoid sudden surprise software issues during your computing session.
This is no different for hardware like the Apple Vision Pro, as it is still a computer in its own right, just worn on your head. Sometimes, if an app isn’t working, a restart of the entire device can get things rolling smoothly once again.
