When your Mac experiences a frozen or locked screen, it can be frustrating and affect your productivity. Fortunately, there are practical solutions you can try to fix this problem. In this article, we will provide you with a step-by-step guide to fix a frozen screen on your Mac and restore its functionality. Follow these proven tips to solve this issue effectively.
Step 1: Wait and restart
When you encounter a frozen screen on your Mac, the first thing to do is to wait a few minutes before taking drastic action. Sometimes the system will recover on its own and return to normal. If after a few minutes the screen is still frozen, the next step is to restart your Mac. Press and hold the power button until the computer shuts down, then press it again to restart. Restarting the Mac can resolve temporary problems and restore proper operation.
Step 2: Force applications to close
If the frozen screen is due to a specific application, you can try to force close that particular application. Press Command + Option + Esc keys at the same time to open the «Activity Monitor». Then select the problematic application and click «Force Quit». This will close the application and may fix the frozen screen problem.
Step 3: Start in safe mode
Starting your Mac in safe mode can help identify and fix problems related to conflicting device drivers or extensions. To start in safe mode, hold down the Shift key during startup until the Apple logo appears. If your Mac starts up successfully in safe mode, restart it again to return to normal mode. This may be helpful in resolving persistent frozen screen problems.
Step 4: Verify and repair the disk
A hard disk with errors or corrupted files can cause freezing screen problems on a Mac. Use «Disk Utility» to check and repair the disk for possible problems. Open the «Disk Utility» application from the «Utilities» folder in the «Applications» folder. Select your hard drive in the left pane, go to the «First Aid» tab and click «Repair Disk». This will search for and fix possible disk problems, which may resolve the frozen screen.
Step 5: Reset System Management Control (SMC) and NVRAM/PRAM memory
Resetting the System Management Control (SMC) and NVRAM or PRAM memory can help troubleshoot frozen screen problems. The exact steps to reset SMC and NVRAM/PRAM vary depending on your Mac model. Please refer to Apple's official documentation or support website for precise instructions on how to perform these procedures.
