How to Fix Black Screen After macOS Big Sur Update

If you recently updated your Mac to macOS Big Sur and are now experiencing a black screen, you are not alone. Many Mac users have reported encountering this issue, which can be frustrating and even debilitating. In this blog post, we will discuss several solutions that can help you fix the black screen problem after the macOS Big Sur update.

It is important to address this issue as soon as possible because a black screen can prevent you from accessing your files, applications, and other important data. By following the steps outlined in this post, you can restore your Mac's functionality and get back to work.

Reset your SMC

The first solution you can try is resetting your System Management Controller (SMC). The SMC is responsible for controlling several hardware components on your Mac, including the power button, battery, and fans.

To reset your SMC, follow these steps:

1. Shut down your Mac.

2. Unplug the power cord.

3. Wait for 15 seconds.

4. Plug the power cord back in.

5. Press the power button to turn on your Mac.

Resetting the SMC can fix several issues, including a black screen problem. It is a simple process that can be completed in a few minutes.

Reset your NVRAM

The next solution you can try is resetting your Non-Volatile Random-Access Memory (NVRAM). The NVRAM stores important system settings, such as the volume level, startup disk selection, and screen resolution.

To reset your NVRAM, follow these steps:

1. Shut down your Mac.

2. Press the power button to turn on your Mac.

3. Immediately press and hold the Option + Command + P + R keys.

4. Hold down the keys until you hear the startup sound twice.

5. Release the keys.

Resetting the NVRAM can also fix several issues, including a black screen problem. It is another simple process that can be completed in a few minutes.

Reinstall Big Sur Through Recovery Mode

If resetting your SMC and NVRAM does not fix the black screen problem, you can try reinstalling macOS Big Sur through Recovery Mode. Recovery Mode is a built-in feature on Macs that allows you to troubleshoot and solve common issues.

To reinstall Big Sur through Recovery Mode, follow these steps:

1. Shut down your Mac.

2. Press the power button to turn on your Mac.

3. Immediately press and hold the Command + R keys.

4. Release the keys when you see the Apple logo or a spinning globe.

5. Select "Reinstall macOS" and follow the on-screen instructions.

Reinstalling Big Sur can fix any corrupted or missing system files that may be causing the black screen problem. It is more time-consuming than resetting the SMC and NVRAM, but it is still a relatively simple process.
