MacBook Pro 14" (M1 Pro) display blinks once on login view after booting

MGuzman! Thanks for stopping by and posting about this for it truly needs to be put under review by staff.

I'm sorry to hear that you're experiencing a display blinking issue with your MacBook Pro. While I can provide some general troubleshooting suggestions, it's important to note that this issue may require further investigation by Apple Support or a certified technician. Nevertheless, here are a few additional steps you can try:

• Reset the NVRAM/PRAM: Restart your MacBook Pro and immediately press and hold the Option + Command + P + R keys until you hear the startup chime for the second time. This will reset the NVRAM (Non-Volatile Random-Access Memory) or PRAM (Parameter RAM), which stores certain settings related to display and startup.

• Boot in Safe Mode: Restart your MacBook Pro and hold down the Shift key while it's booting until you see the Apple logo. This will boot your Mac into Safe Mode, and it will perform various checks and disable unnecessary extensions and startup items. Check if the display blinking issue occurs in Safe Mode. If it doesn't, it suggests that a third-party app or extension may be causing the problem.

• Create a new user account: Create a new user account on your MacBook Pro and see if the display blinking issue persists when logging in with the new account. If the issue doesn't occur with the new account, it could indicate a problem specific to your user account settings or configurations.

• Update macOS: Check for any available macOS updates by going to the Apple menu > System Preferences > Software Update. Install any pending updates and see if it resolves the issue. Keeping your system up to date can often address software-related issues.

If none of these steps resolve the problem, it's recommended to contact Apple Support or visit an Apple Authorized Service Provider for further assistance. They can provide more specific guidance and perform diagnostics to identify any underlying hardware or software issues that may be causing the display blinking problem.

Keep me posted with any updates on your situation,

Experiencing the same problem as well. What could be the problem of this? Can we do anything about it?

I am having the same issue. Has anyone found the solution?

Same issue here and it started suddenly while reading a PDF.

At first I thought it may be the TrueTone or Auto Adjust screen brightness but after trying everything as well, it happens even during booting up.

if it is hardware, would this be something covered in the warranty ?

in EU all electronic devices should be coved by a 3 year warrenty according to EU law but not all Apple information states that. It took me a while to find Portuguese law (Decreto-Lei n.o 84/2021, de 18 de Outubro).
