Let's take a look -

Fix 1. Check the Power

The most common cause of Mac's black screen is the lack of power. In that case, the solution is straightforward. You need to check if your system has enough power. In that case, check the battery percentage or health and ensure it is complete for efficient functioning.

MacBooks generally show an icon where you can view whether the battery charging is taking place. Macs and iMacs are designed to prevent them from turning on when not connected to a power source. Another thing you need to check is if there is an issue with the plug where you connect the Battery.

Check the Power

Fix 2. Disconnect All the Peripherals

After you have checked the power source, you need to look at the peripherals. You use many peripheral devices daily, including a keyboard, mouse, AirPods, Trackpad, external hard drive, etc. These peripherals' malfunctions occasionally conflict with the MacBook and cause system freezing. Disconnect all of them and see if the issue is resolved.

Unplugging a mouse or keyboard is simple, but you still need to open the accessories. However, it is a little different in the case of an external storage device. You must choose the item in this case, then File, and click the "Eject" afterward.

Fix 3. Adjust Your Mac Display's Brightness

Did you check the brightness level of your Mac screen? Sometimes, the brightness level is turned way down, or it might have reduced drastically. In that case, turn the screen brightness and see if the problem is fixed!

Step 2. Once the system turns off, wait for some time.

Step 3. Now, press the power button to turn it on.

Step 2. After a few seconds, please turn it on.

Open System Settings in Mac
