There could be several reasons your MacBook screen is flashing, or you are seeing flickering lines on certain occasions. We’ll quickly enlist a few of them –

2. Open Displays.

System Preferences

3. Click on the Display tab.

4. Uncheck the Automatically Adjust Brightness and True Tone checkboxes

3. Reset PRAM or NVRAM

An outdated or cluttered NVRAM (Non-volatile random-access memory) or PRAM can be the culprit behind your MacBook’s screen flickering. In such a case, you can reset your NVRAM and then check if the issue persists or not –

1. Power off your Mac.

2. Immediately reboot your Mac and hold down the P + R + Command + Option keys for 20 seconds.

3. Click on Software Update

4. If an update is available, click Upgrade Now and follow the on-screen instructions.

Once your MacBook restarts, check if the issue is resolved and if your Macbook or Mac’s screen is still flickering or not. It is also advisable to take a backup of the data on your Mac before you fetch the update so that you will at least have your backed-up data in place in case something goes wrong. For backing up data, you can also try a third-party utility.

5. Clear System Junk and Cache

Redundant system junk and cache can take up Mac’s storage and, at the same time, even impair your Mac’s performance. One of the best ways to remove these unneeded items is to use Mac cleaning software. CleanMyMac X, for instance, is one of the best mac cleaners available.

In simpler terms, in this mode, you may be able to get rid of third-party services that affect screen parameters; hence, the MacBook screen flickering that you were seeing in normal mode may not appear in Safe Mode. To boot Mac in Safe Mode, here are the steps –

1. Shut down your MacBook.

2. Reboot it while holding the Shift key until you see the login screen

3. Once your MacBook has rebooted in the Safe Mode, check if you still see any screen blinking or flickering lines.
