I have a Macbook Pro 14 inches and when I start it, after entering the password the screen flashes and stays black for a few seconds and then, when I return to the view again and display the desktop, it flashes again for a few seconds and returns. After these 2 blinks, the problem no longer occurs and the same thing repeats when starting the computer again. Does anyone know how to solve it?
MacBook Pro 14″, macOS 13.3
Hey lucalac1989,
Let’s see if resetting the NVRAM helps with this: Reset NVRAM on your Mac - Apple Support. Since you didn’t mention the year, please double-check if you’re using a Mac with Apple Silicon or an Intel-based Mac, then follow the steps.
If you still see flickering, try restarting your Mac in safe mode: How to use safe mode on your Mac - Apple Support
We want you to be aware that restarting in safe mode may take a bit longer than usual since it prevents some software from loading and does a check of your startup disk. You may also see some graphic anomalies or flickering on your screen as well.
After you’re Mac is in safe mode, restart your Mac normally to see if the flickering continues.
Please let us know the results when you're able.
All the best.
