In this video I show you how I create a Windows 11 bootable USB on a Mac in about 5 minutes, using Terminal—no extra apps, no complicated steps. I start by downloading the official Windows ISO from Microsoft, then I use a few simple diskutil commands to identify the USB, erase it properly, and unmount it so macOS doesn’t interfere while we write the image. The key step is using the dd command to copy the Windows ISO directly onto the USB drive. I walk through the exact command I use (including the faster /dev/rdisk option and a bs=1m block size), and then I finish by ejecting the drive cleanly. If you’re installing Windows for gaming, work, or testing, this method works across macOS versions like Big Sur, Monterey, and Ventura—as long as you’re careful to pick the correct disk number so you don’t wipe the wrong drive.
