I have some trouble with my MacBook Pro screen : on it appeared a transparent strip. It's visible from the MacBook start and I can't make it disappear. However, I still can click on files, softwares...
I've already tried :
- Many restarts
- Safe mode
- Reset NVRAM
- Apple Diagnostics
When I plug another screen with HDMI I don't see it on 2nd screen.
Weird thing is that this strip has disappear once after using a full screen app for some time. But today after 2 days without using it, it's now more visible and flashes when I'm on some apps (but not flashing on desktop).
