Yellow border around screen (Not bad hardware, software issue)

Hi All -


I set up a new Macbook pro yesterday. Today after handing it off to the end user, he started getting this yellow border around the display. I can get it to go away for a little while by creating a new desktop in mission control. It keeps coming back though. I attached a screenshot to show what it looks like. Has anyone seen this? How can I make it go away?

Hello zmmeyer20,



Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are having an issue with a yellow border on this MacBook Pro. You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.



How to test an issue in another user account on your Mac



Next, use safe mode to start up this Mac as it does the following things:



  • Verifies your startup disk and attempts to repair directory issues, if needed
  • Loads only required kernel extensions
  • Prevents Startup Items and Login Items from opening automatically
  • Disables user-installed fonts
  • Deletes font caches, kernel cache, and other system cache files



Log in to your user account and test the issue while in safe mode and then restart normally and test the issue again.



Use safe mode to isolate issues with your Mac

Graphics performance limited in macOS Recovery, safe mode, or Guest User mode



Cheers!
