Question: High sierra screen flash

My macbook pro (late 2013, iris pro graphic card) encounters screen flashing problem after I erased the disk and re-intalled High Sierra (10.13.1). The flashing occurs occasionally, it is like the whole screen turns off and on rapidly.


Before I made this re-install, I also ran High Sierra that is upgraded from Sierra, and no such problem existed. Is anyone has the same problem with me? Is there any way we can fix it?


Thanks,

MacBook Pro (Retina, 15-inch, Late 2013), macOS High Sierra (10.13.1)

Hi gangfromlincoln,

Thanks for reaching out in Apple Support Communities. I understand that since erasing your disk and reinstalling macOS High Sierra, you're seeing an occasional flash from your display. I know it's important for your Mac to operate as expected and I'd like to help. First, I'd recommend following the steps here to reset the NVRAM on your Mac: How to reset NVRAM on your Mac

Take some time to test and see if the behavior continues. If so, use these steps to reset the SMC and test again: How to reset the System Management Controller (SMC) on your Mac

Let me know what you find.


Best Regards.

Chris,


I reset the NVRAM and SMC. By the way, after I posted my question, I recover my computer to Mac OS 10.9, which was the OS it shipped to me. Then, I upgraded to 10.12 and 10.13, I try to reset NVRAM while it was installed with 10.12, the problem still existed.


I just try to reset a few minutes ago. While I using Mathematica and Safari, the screen still flashes occasionally.


Do you think I need to go the genius bar to check the computer? ( I have ran the diagnostic program, and no problem was found)


Thank you!

Hi gangfromlincoln,

Thank you for taking the time to work through those steps and for providing the other steps you've taken. Based on this information, you'll want to have the Mac examined by an Apple Authorized Service Provider or the Apple Store. You can find the nearest locations to you here: Find Locations
