Winbake app showing step 1 — pick a Windows ISO

Why this exists

Sooner or later a Mac user needs to install Windows on a PC — a family laptop, a dev box, a gaming build. The accepted way to do it is to boot from a USB stick. Getting that stick made on a Mac is unreasonably annoying.

Microsoft Media Creation Tool

Windows-only.

It's the tool that actually works — produces a USB Windows Setup is happy with. But it only runs on Windows, which is the whole problem you were trying to solve.

Balena Etcher & friends

Hit or miss.

Flashes ISOs fine, but Windows installer ISOs are a special case: UEFI boot, GPT layout, an install.wim that often exceeds FAT32's 4 GB file limit. Generic flashers miss one of those and you end up at a black screen on boot.

dd in Terminal

One typo from wiping your Mac.

Works if you get every flag right. Nobody wants to memorize hdiutil, diskutil, wimlib-imagex split, and pray they didn't mix up /dev/disk2 with /dev/disk0.

Winbake

Just works.

Drop in the ISO. Pick the USB. Hold to bake. Winbake does the partitioning, formatting, copy, and install.wim split for you — and the boot disk is never even in the list.

How it works

  1. 1

    Pick a Windows ISO

    Drop in any Windows 10 or 11 installer ISO — bring your own from Microsoft.

  2. 2

    Pick a USB drive

    Winbake lists only removable drives. Your boot disk is never in the list.

  3. 3

    Hold to bake

    A 3-second press-and-hold guards against accidents. Winbake partitions, formats, and copies.

  4. 4

    Boot your PC

    Plug in, boot from USB, install Windows. GPT + FAT32, UEFI-ready out of the box.

What you get

SwiftUI. No Electron, no Java, no Boot Camp Assistant. <5 MB download.

Safe by default

Boot disk filtered. Target drive named back to you. 3-second hold confirm before writing.

Signed & notarized
