Here's a short guide on extracting the IPSW firmware image from Apple's iOS beta DMG archive. If you're a Windows user and you'd like to update to iOS beta, this is an essential step.

Registered developers can download iOS firmware files from Apple's Developer Centre. These files are typically provided as IPSW files, but are wrapped up inside DMG files. There's a different install for each compatible device, so make sure your download matches the correct install for your device.

  1. Open DMG Extractor and select the iOS Beta DMG file you want to extract

    Click "Open" on the top-left Menu icon.

  2. Extract the IPSW restore file inside the DMG file of iOS beta

    You just want the IPSW restore file so on the Extract button menu click "Selected files to…".

    When extracting a progress bar will show until the extraction process is completed.
