How to install macOS 27.2 with this IPSW

  1. Back up your Apple Virtual Machine 1 to iCloud or your computer — restoring erases the device.
  2. Turn off Find My in Settings → [your name] → Find My.
  3. Connect the device with a cable and open Finder (macOS Catalina or later) or Apple Devices / iTunes (Windows).
  4. Hold Option (Mac) or Shift (Windows) and click Restore. Choose UniversalMac_27.2_26B123_Restore.ipsw.
  5. Wait — the device restarts several times. Don’t disconnect it until you see the Hello screen.

Stuck on the Apple logo? Put the device into recovery mode first, then restore.
