To convert a Dmg file (which is a disk image file, typically used for macOS) to an ISO file, you can use Dmg2ISO or Disk Utility (built into macOS). Below are the steps for both methods:
✅ Method 1: Using Dmg2ISO (Command Line)
Requirements:
- macOS with Xcode command line tools installed
dmg2isotool (you can install it via Homebrew)
Step 1: Install dmg2iso via Homebrew
brew install dmg2iso
Step 2: Convert Dmg to ISO
Open Terminal and run:
dmg2iso -o output.iso /path/to/your.dmg
output.isois the output ISO file./path/to/your.dmgis the path to your dmg file.
✅ Method 2: Using macOS Disk Utility
Steps:
- Open Disk Utility from the Applications > Utilities folder.
- Select the dmg file you want to convert.
- Click "Show Package Contents".
- Select the "Disk Image" inside the package.
- Click "File" > "Export".
- Choose a location to save the ISO file.
- Select "ISO Image" as the format.
- Click "Save".
✅ Method 3: Using Third-Party Tools
If you don't want to use command line or Disk Utility, you can use:
- Macrium Reflect (free version available)
- ImgBurn (Windows, but can be used on macOS via Wine or Docker)
- PowerISO (free, supports dmg to iso)
✅ Notes:
- Ensure the dmg file is not corrupted.
- Some dmg files may not be directly readable by macOS, so you may need to extract the contents first.
- If you're converting a sparse image, you may need to use a different tool.
If you're using Windows, you can use ImgBurn or PowerISO to convert dmg to iso.
