How to Fix MacBook Won’t Start After Update

If you own a MacBook, you know how frustrating it can be when it won't start, especially after a software update. You may have encountered this issue before, and you know how much of a headache it can be. In this blog post, we will discuss some troubleshooting steps you can take to fix your MacBook when it won't start after a software update.

Check Your MacBook's Battery

The first thing to check is your MacBook's battery. If your MacBook's battery is not charged, it may not start up, even if it is plugged in. To check if your battery is the issue, follow these steps:

1. Connect your MacBook to a power source.

2. Press and hold the Shift + Control + Option keys and the power button simultaneously for 10 seconds.

3. Release all the keys and the power button.

4. Press the power button to turn your MacBook back on.

If resetting the System Management Controller (SMC) does not resolve the issue, you may need to replace the battery.

Check Your MacBook's Hardware

If your MacBook's battery is not the issue, it's time to check its hardware. A hardware issue may be preventing your MacBook from starting up. To run a hardware diagnostics test, follow these steps:

1. Connect your MacBook to a power source.

2. Press and hold the D key and the power button simultaneously until the Apple Hardware Test (AHT) screen appears.

3. Follow the on-screen instructions to run the diagnostics test.

If hardware issues are detected, you may need to take your MacBook to an Apple Store or an authorized service provider for repair.

Boot in Safe Mode

1. Turn off your MacBook.

2. Press the power button to turn it back on.

3. Immediately press and hold the Shift key.

4. Release the Shift key when the login screen appears.

If safe mode does not resolve the issue, you may need to reinstall macOS.

Reinstalling the macOS may be necessary to resolve the issue. Before you reinstall macOS, make sure you have backed up all your important files. To reinstall macOS, follow these steps:

1. Turn off your MacBook.

2. Press the power button to turn it back on.

3. Immediately press and hold the Command + R keys until the Apple logo appears.
