Apple used to provide direct DMG links via developer.apple.com/download/more/. As of 2025, Apple has moved most distribution to the App Store, but registered Apple Developers can still access older DMG versions.
| Cause | Explanation | |-------|-------------| | Corrupt IPSW | The iPhone/iPad software file downloaded by Apple Configurator is incomplete or damaged. | | USB Timing Out | A slow or faulty USB cable causes the handshake between the Mac and the device to time out. | | Incompatible macOS | Running an outdated version of macOS that lacks required security or driver updates. | | Apple Configurator Version Mismatch | An old version of Configurator trying to restore a device with a newer iOS/iPadOS version. | | Security Software Interference | Anti-virus or firewall software blocking the DFU (Device Firmware Update) communication. |
Critical note: Error 2133 often appears on the Apple T2 Security Chip or Apple Silicon Macs when attempting to restore iOS devices via a USB-C hub. Always connect directly to the Mac’s built-in port.
If you hit error 2133 while using a .dmg in Apple Configurator, the file is likely wrong or damaged. Re-download from Apple’s official “Configurator Restore” resources (not third-party sites). For most admins, Configurator is essential but finicky – use .ipsw for iOS/tvOS, and double-check firmware for Mac restores.
Rating for DMG-based restores: ⭐⭐☆☆☆ (2/5 – due to cryptic errors like 2133)
