UltraDMG, the best app for creating macOS bootable USB installer on a PC.

Requirements

  • A Windows PC.
  • A USB flash drive 16 GB or larger (all data will be erased).
  • The macOS 26 Tahoe installer image in .dmg format.
  • The UltraDMG software.

How to make macOS Tahoe bootable USB from Windows PC

1. Plug in your USB drive.

2. In the main interface, click the Burn macOS and locate your USB under the Drive List.

3. Right-click the USB drive and select Format Disk for Mac.

4. Confirm formatting (this erases all data).

5. Right-click the USB drive again → choose Restore with Disk Image.

6. Browse and select your macOS Tahoe .dmg.

7. Click OK and confirm overwriting the USB.

8. Wait for the process to complete (can take 15–45 minutes depending on USB speed.)

UltraDMG is one of the easiest ways to create a macOS bootable USB on Windows 11 or Windows 10 PC. It works well if you already have the macOS .dmg file and need a Mac installer without access to another Mac.
