Screen flickering

I have macbook pro 13 2020 Model. It does this weird thing, it goes green and some random rainbow colours blink for 2 to 3 seconds and turn off during shut down.

Does it have display problem or any other screen issues?

Why does this issue raises?

It does do such blink or flickering while operating the laptop, it only does this when shut down.


May i please know what could be the problem?



Thank you.

MacBook Pro 13″, macOS 12.4

To trouble shoot further you can:


—Test issue in another user (or guest user) account Set up users, guests, and groups on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 



—SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies


Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, font cache, etc.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.
