  • Look in Configurator: The dead Mac’s icon will appear as "DFU" (a blank screen icon).
  • Action > Restore: Right-click and select "Restore." This will download the correct 2021 firmware (or use a local .ipsw you have saved).

    • Apple’s internal build numbers for macOS components are often 4-digit numbers. For example, the T2 bridgeOS build for a specific 2021 update might have contained "2133" somewhere in its plist. When searching for a .dmg that contains a specific BridgeOS update, you may have stumbled upon a forum post referencing that number.
