Flashing/flickering light on touch bar.

Hi Melonsho3s,

Thanks for using Apple Support Communities! I see you have an unusual issue with your Touch Bar, and I'd like to do what I can to help out.

This may end up being a hardware issue. However, there is some troubleshooting to verify is not software related.

If you've performed any of these steps already, just move on to the next one.

Verify if this happens with a particular app. If so, see if there is an update available in the Mac App Store. How to update the software on your Mac Or uninstall the app and if the issue stops, contact the app developer to let them know what's happening.

If the issue seems system wide:

Reset SMC and NVRAM.

Reset NVRAM or PRAM on your Mac

Start in safe mode. Keep in mind, it may take longer to finish the start up, as safe mode does some system checks, and can sometimes resolve issues. You'll also see some differences in the display. This is expected with safe mode, and when you restart normally, they'll be gone. How to use safe mode on your Mac

Test in another user. If you don't have one, here's how to create one for testing: How to test an issue in another user account on your Mac

Take care!

Hey Melonsho3s,

Thanks for the reply and performing those steps, we appreciate it!

This is certainly an unusual issue. Since it's been persistent, I'd recommend contacting Apple Support. Let them know what's happening and the troubleshooting you've done.

Enjoy your day and be well!
