Create a Windows 11 USB on macOS
Create FAT32 installer media from a Windows ISO. Split oversized WIM files when needed.
macOS support
Bootable supports Apple Silicon. It accepts whole removable drives and rejects the macOS system disk.
Bootable mounts the ISO read-only. It creates GPT or MBR FAT32 media with diskutil.
Requirements
- An Apple Silicon Mac.
- A trusted Windows 11 ISO.
- An expendable USB drive with enough capacity.
wimlibwhen the ISO contains an oversized WIM or CA 2023 files are requested.
brew install wimlib
curl -fsSL https://bootable.palash.dev/install.sh | sh -s -- --guiThe release is not signed or notarized. Verify the release SHA-256 file before running it.
Write helper
The installer adds the root-owned helper at /Library/PrivilegedHelperTools/app.bootable.helper. The desktop app runs without administrator access.
Create the installer
- Open the Windows 11 ISO in Bootable.
- Select the USB drive by its physical model and capacity.
- Choose GPT or MBR and the Windows setup options.
- Review the source, drive, operations, and erasure warning.
- Confirm erasure and authenticate.
- Keep the drive connected until the media check finishes.
Media checks
Bootable checks the UEFI files, setup payload, split WIM parts, and FAT32 limits. A cancelled write is marked incomplete.
This does not guarantee that Windows Setup will finish.
