3. Step-by-Step Guide: Burning macOS to USB (The Main Use Case)
This is the most common reason people use this tool: creating a Hackintosh installer or a boot drive for a Mac using a Windows PC.
Prerequisites:
- A Windows PC.
- A USB flash drive (at least 16GB recommended; 32GB is safer).
- IMPORTANT: The USB drive will be completely erased. Back up any data on it first.
- A macOS DMG file (e.g.,
Install macOS Ventura.dmg or Monterey.dmg).
The Process:
- Launch the Software: Open UUByte DMG Editor. You will see three tabs: Burn, Extract, Edit. Click on the Burn tab.
- Import DMG File: Click the "Browse" or "+" button to locate your macOS DMG file.
- Select the USB Drive: Plug in your USB drive. The software should auto-detect it. If not, click the refresh icon. Ensure the correct drive is selected to avoid data loss on other drives.
- Configure Options:
- Format: Usually defaults to the correct settings for macOS booting.
- Check for Update: (Optional) Keeps the software current.
- Start Burning: Click the Burn button.
- The software will format the USB drive.
- It will then write the DMG contents to the drive. This can take anywhere from 10 to 30 minutes depending on the speed of your USB drive and the size of the macOS version.
- Completion: Once finished, the status bar will show "100%" and usually a "Success" prompt. Safely remove the USB drive.
Troubleshooting tips
- If an encrypted DMG won’t open, verify the password and try mounting with hdiutil for a second opinion.
- For permission errors, check file ownership and run the app with appropriate privileges.
- If edits fail, work on a copy of the DMG and verify integrity after saving.
