Bright, white light and unresponsive Launch Bar on M1 MacBook Pro

I am using a 2020 M1 MBP running MacOS26. A few days ago I was taking it with me so I closed the lid and when I arrived at my destination and opened the lid the LaunchBar started flashing a bright, white light. It eventually stopped.

Going back home I did the same thing, closed the lid and when I got home and opened the lid the LaunchBar flashed a bright, white light. It eventually stopped but then my LaunchBar was black. No response.

Today I ran Safe Boot and that seemed to fix it but I did see that bright, white light just in the right corner of the LaunchBar upon booting up. It went off quickly.

A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test.

if your issue continues —

you run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.

Use Apple Diagnostics to test your Mac for hardware issues

leroydouglas-I did all the Diagnostics and all tested just fine. I didn't know about that test. So I guess all is ok then?

Yep, it sounds like you sorted the glitch with the SafeBoot.

Good computing mrstee !
