Steps:

Step 1: Check Your Energy Saver Settings

Explanation:

This is the most obvious step but is often overlooked. If your Mac’s energy saver settings are set to put the display to sleep after a certain period of inactivity, it might be the reason why your screen goes black. You can change this in System Preferences- Energy Saver and adjust the settings accordingly.

Step 2: Reset SMC (System Management Controller)

Explanation:

If your Mac’s hardware (specifically, the SMC) is not functioning properly, it can cause your screen to go black. To reset the SMC, you need to follow specific instructions depending on the Mac you’re using. Check Apple’s support page for step-by-step instructions.

Step 3: Reset NVRAM (Non-Volatile Random Access Memory)

Explanation:

Similarly, resetting the NVRAM can help you fix any problems that are causing your Mac’s screen to black out. It can be done by following a few steps that are specific to your Mac model. You can find the instructions by visiting Apple’s support page.

Step 4: Check Your Screen Saver Settings

Explanation:

Another reason for a black screen might be your Mac’s screen saver settings. Make sure to set it to a longer duration or turn it off altogether. You can access your screen saver settings in System Preferences- Desktop & Screen Saver.

Step 5: Check Your Display’s Cable & Adapter Connections

Explanation:

Your Mac’s screen going black might be because of loose connections between your display and adapter or cable. Ensure that the wires and connectors are secure and working correctly.

Step 6: Disable Automatic Graphics Switching

Explanation:

One of the causes of your Mac’s screen blackouts could be the automatic graphics switching between your Mac’s integrated and discrete graphics processing units (GPUs). To disable automatic graphics switching, go to System Preferences- Energy Saver- uncheck the Automatic Graphics Switching box.

Step 7: Update Your Mac Operating System

Explanation:

Outdated operating systems can also cause your Mac’s screen to go black. Make sure to update your system by going to System Preferences- Software Update.

Step 8: Run Diagnostics or Hardware Test

Explanation:

If you’ve tried all the previous steps and still cannot resolve the issue, then there might be an underlying hardware problem. You can run a diagnostic or hardware test by restarting your Mac and holding down the D key.

Step 9: Check For Apps That Might Be Causing the Issue

Explanation:

Certain apps or software with compatibility issues could cause your screen to go black. Try quitting the suspected app, or reinstalling it altogether.

Step 10: Disconnect External Devices

Explanation:

External devices like printers, scanners, or hard drives might be interfering with your Mac’s screen. Disconnect them all, and then try reconnecting one at a time to check which device is causing the issue.

Step 11: Check for Overheating

Explanation:

If your Mac overheats, it can cause your screen to go black. Make sure your Mac is not sitting in direct sunlight, and that the fans are working properly.

Step 12: Visit an Authorized Apple Service Provider

Explanation:

If none of the above steps work, don’t worry- there’s still hope. Visit an Apple service provider and let a professional diagnose the problem and fix it for you.
