How do I fix the black screen of death on my imac?

Answered by Willie Powers

When faced with the black screen of death on your iMac, there are several DIY methods you can try to fix the issue. Here are 10 possible solutions:

1. Check your power adapter, cable, and battery: Ensure that your iMac is receiving power by checking the power adapter, cable, and battery. Make sure they are all functioning properly and connected securely.

2. Detach peripheral devices: Disconnect any external devices such as printers, scanners, or external hard drives from your iMac. Sometimes, incompatible or faulty peripherals can cause the black screen issue.

3. Check display settings on Mac: Press the “Option” key and simultaneously click on the “Brightness” button on your keyboard to check if the display settings are causing the problem. Adjust the brightness level and check if the screen comes back to life.

4. Force shutdown or restart Mac: Press and hold the power button on your iMac for about 10 seconds until it shuts down completely. Then, press the power button again to restart your Mac. This can sometimes resolve the black screen issue.

5. Power cycle your Mac: Disconnect the power cord from your iMac and wait for about 10 seconds. Then, reconnect the power cord and turn on your Mac. This can help reset the power and potentially resolve the black screen problem.

6. Repair Startup disk with Disk Utility: Restart your iMac and hold down the “Command” and “R” keys simultaneously until the Apple logo appears. This will boot your Mac into Recovery Mode. From there, select Disk Utility and run First Aid to repair any disk errors that may be causing the black screen issue.

7. Reset the System Management Controller (SMC): Shut down your iMac and disconnect the power cord. Hold down the “Shift + Control + Option” keys along with the power button for about 10 seconds. Release all the keys and reconnect the power cord, then turn on your Mac. This can reset the SMC and potentially fix the black screen problem.

8. Reset NVRAM/PRAM: Shut down your iMac and turn it back on. Immediately press and hold the “Command + Option + P + R” keys until you hear the startup chime for the second time. This will reset the NVRAM/PRAM and may resolve the black screen issue.

9. Safe Boot: Restart your iMac and hold down the “Shift” key until you see the Apple logo. This will boot your Mac into Safe Mode, where only essential system processes are loaded. If your Mac starts up successfully in Safe Mode, restart it normally and see if the black screen problem is resolved.

10. Seek professional help: If none of the DIY methods work, it may be necessary to consult an Apple Authorized Service Provider or Apple Support for further assistance. They can diagnose and fix any hardware-related issues that may be causing the black screen problem.
