My Mac has an issue where sometimes the primary monitor won't wake up, but the Mac thinks it is connected. So In such cases, I only see my secondary (much smaller) monitor.
Typically I cannot find the mouse cursor so I'm left with a monitor but no way to do anything. Restarting fixes it but I end up having to force-power-down by holding the MacMini power button then restarting... is there a way I can access the Restart menu option in this scenario instead?
