Hi,

If your MacBook Pro has Intel Processor, resetting SMC could solve the issue.

If it doesn't help, try to startup in Safe mode, then normal boot could solve the problem.

Im having the same issue. I started to get the flickering after the OS Update to 11.5.2. I tried to reset the SMC (Left side CTRL-OPTION-SHIFT + Power) . I have an Intel 2016 MacBookPro 13" with 3.3GHz i7. Its still flickering.


The display works as expected with a second monitor or in Safe Mode. As soon as I normal boot without the external monitor its still flickering. As mentioned, the flickering does not happen in Safe Mode.


Any ideas?
