Flickering on the screen of your MacBook can be a frustrating issue, but fortunately, you can fix it with a few simple steps. Here are some of the most common causes of Mac screen flickering and what you can do to resolve the problem:
Update your operating system
Install the most recent version of your operating system. Incompatible or out-of-date software is one of the most common causes of a MacBook's screen flickering. By selecting "System Preferences" > "Software Update" from the Apple menu in the top-left corner of your screen, ensure that your operating system is up to date. Assuming there is an update accessible, introduce it and restart your MacBook.
Change the refresh rate of the screen.
A high refresh rate is another cause of the screen flickering. Select "Displays" from the "System Preferences" menu to resolve this issue. Pick "Default for show" and then click on "Scaled". Test changing the refresh rate to 60 Hz to see if the problem still exists.
Check your cables and connections
Make sure your MacBook is securely connected to an external display or other peripheral devices by checking the cables and connections. Screen flickering can be caused by a loose or damaged cable on occasion. Try replacing your cables if you find any issues.
Boot your MacBook in Safe Mode
Booting your Mac in safe mode can help diagnose and resolve the flickering screen issue. Switch off your MacBook and afterward hold down the Shift key while squeezing the power button to turn it back on. When you see the Apple logo, press and hold the Shift key. Incompatible software or login items may be the cause of the flickering problem if it is resolved. To resolve the issue, try removing any recently installed software and login items.
Reset the System Management Controller (SMC)
A chip that controls your MacBook's power management features, including the display, is the System Management Controller (SMC). Screen flickering issues can be resolved by resetting the SMC. To do this, shut down your MacBook, hold down the Shift + Control + Option keys along with the power button for 10 seconds. After that, release each key and start your MacBook normally.
Disable automatic graphics switching
On some MacBook models, automatic graphics switching can cause screen flickering. To disable it, go to "System Preferences" > "Energy Saver" and uncheck "Automatic graphics switching".
Reset the NVRAM and PRAM
Resetting the NVRAM and PRAM can also help in resolving issues with screen flickering. Shut down your MacBook, then hold down the Command + Option + P + R keys simultaneously while pressing the power button. Keep holding down the keys until you hear the startup sound twice, then release the keys and let your MacBook start up.
Check for hardware problems
If none of the above steps have resolved the screen flickering issue, it's possible that there is a hardware issue with your expensive MacBook. You should contact an experienced gadget repair professional for MacBook repair in Richardson to have your MacBook diagnosed and repaired.
