Dimmed screen 48
Occasionally you may see a dimmed screen on your Mac, saying you have to restart your computer. This can be caused by a number of issues, from corrupted system updates to a serious hardware failure. Restart the Mac as it suggests. If you see more “kernel panics,” disconnect any peripherals and try starting up in safe mode ( bit.ly/macossafe) to see if the issue persists there. If the issue does continue, contact Apple Support for further help.
