All of Apple's latest Macs support macOS Sonoma. However, sometimes when installing a software update, you might run into an unexpected error. This may result in, worst case scenario, a bricked Mac. Specifically, your computer would fail to boot properly, typically resulting in an endless boot loop that displays the Apple logo. However, you don't need to worry; it's possible to revive your bricked Mac. Just follow the steps below.

How to revive a bricked Mac

  1. Depending on the processor in your bricked Mac, you have to do either of the following:
    • If it has an Apple silicon processor — such as the M1 or M2 chip — then turn on your Mac and click and hold on the Power button. Release once you see the startup options window. After that click the Options button that has a gear icon, then click Continue.
    • For Intel-powered Macs, turn your computer on, then press and hold Command + R until you see the Apple logo.
  2. You may be asked for the user password. In this case, type the one you use to unlock your bricked Mac.
  3. Click on Disk Utility, followed by Continue.
  4. Tap on the startup disk (usually named Macintosh HD).
  5. Click on Erase, and confirm that you want to erase it.
  6. Tap the red close button once the erasure concludes.
  7. Click on Reinstall macOS and tap on Continue.
  8. Follow the stated instructions and agree to Apple's terms after reading them thoroughly.
  9. The latest stable macOS version will then download and install. Keep your Mac connected to a power source during the process.

Always keep a backup of your important files on an external hard drive or cloud service. Our computers could die for different reasons, and the revival methods tend to delete all user data. It's always better to be safe than sorry, and enabling an auto-sync mechanism for your important data doesn't require much effort.
