WinUSB Creator for Mac

Create bootable Windows 11 USB drives on macOS

---

Features

• Simple 3-step process — Select ISO, choose USB drive, create installer
• Drag & drop support — Just drop your Windows ISO onto the app
• Automatic format selection — Uses exFAT for large files, FAT32 for compatibility
• No external dependencies — Everything is built-in, no Homebrew required
• Native macOS app — Built with SwiftUI, feels right at home on your Mac

Requirements

• macOS 13.0 (Ventura) or later
• A Windows 11 ISO file (download from Microsoft)
• A USB drive (8GB or larger recommended)

Installation

Download

Build from Source

git clone https://github.com/vcazan/WinUSBCreator.git
cd WinUSBCreator

Usage

1. Select ISO — Click "Choose ISO" or drag and drop a Windows 11 ISO file
2. Select USB — Choose your USB drive from the list (all data will be erased!)

Once complete, restart your Mac and hold the Option (⌥) key to select the USB drive as your boot device.

How It Works

WinUSB Creator handles the complexities of creating a Windows bootable USB on macOS:

• Smart formatting — Automatically chooses exFAT (for files >4GB) or FAT32
• File copying — Streams large files with real-time progress updates
• UEFI compatible — Creates GPT partition table for modern boot support

FAQ

Q: Why does the app need to run outside the sandbox?
A: Creating bootable USB drives requires low-level disk access that isn't possible in a sandboxed environment.

Q: Is this safe to use?
A: Yes, but always double-check you've selected the correct USB drive. All data on the selected drive will be permanently erased.

Q: Can I use this for Windows 10?
A: Yes, it works with Windows 10 ISOs as well.
