Your Mac won't start up? Find out how to repair it

When a Mac won't turn on or locks up at startup, it can be frustrating, but there are several steps you can take to fix it. Here is a clear guide to dealing with this problem.

1. Check the basics

• Power supply: Make sure the Mac is plugged into power and the cable is working properly. If you have a laptop, try another charger if possible.
• Power indicators: Look for lights, a startup sound, or fans running. This provides an explanation of the hardware status.

2. Force restart

If it seems on but does not respond:

1. Press and hold the power button for 10 seconds to turn it off completely.
2. Then press the power button.

3. Perform a restart of SMC (System Management Controller).

The SMC controls basic hardware functions.

• For MacBooks with Intel chip:
  1. Turn off the Mac.
  2. Hold down the keys Shift + Control + Option on the left side and the power button for a period of 10 seconds.
  3. Release all keys and press the power button to turn on the Mac.
• For Macs with M1/M2 chipsTurn off the Mac, disconnect it from the power supply for a few seconds and try again.

4. Start in Safe Mode

Safe Mode can disable third-party extensions and verify the startup disk.

1. Turn off the computer.
2. Hold down the Shift key and turn it on.
3. Release the key as soon as you see the login screen.
4. If the Mac starts up properly, it is possible that some application or extension is causing the problem.

5. Use Recovery Utilities (macOS Recovery)

1. Turn off the computer.
2. Press and hold down the keys Command (⌘) + R when turned on.
3. Access Disk Utility and select the primary disk (named Macintosh HD).
4. Click on the first aid to fix disk errors.

6. Restore macOs

If all else fails, you may need to reinstall MacOS.

1. From MacOS Recovery (⌘ + R), select. Reinstall MacOS.
2. Follow the guidelines on the screen. This will not allow deletion of your files, however, it is always a good idea to have a backup copy.

7. Consider the hardware

• If no initial sound is heard or the Mac device is unresponsive, it could be a hardware problem. In this case, contact Apple technical support or a specialized service.

Final tip: Always keep your system up to date and perform regular backups in order to prevent the risk of data loss in these circumstances.
