Unless you have another Mac, you will need to contact Apple support (link is in upper right corner of this page).

In very rare circumstances, such as when a power failure interrupts macOS installation, your Mac might start up to a circled exclamation point. That means the firmware stored in your computer's memory needs to be revived or restored. You will need these items:

  • Another Mac with macOS Catalina 10.15.6 or later, internet access, and the latest version of Apple Configurator
  • A compatible USB cable to connect the two computers

For complete details, see Revive or restore a Mac with Apple silicon.

If you don't have the items you need, or you need help following the instructions, please contact Apple Support.
