The best way to burn iso to usb on MAC for windows iso?

I had to do the same thing a while back when my mom’s old PC completely refused to boot, and all I had was my MacBook. What ended up saving me was WonderISO — it’s honestly the easiest way to burn ISO to USB on Mac without fighting Terminal commands.

Here are two practical, real-world methods to burn ISO to USB on Mac, explained in a simple way (perfect if you’re not tech-savvy):

(1) The easiest option is WonderISO — it’s a full GUI app that lets you burn ISO to USB on Mac in just a few clicks.

1. Open WonderISO → choose Burn to USB → select your Windows 10 ISO → pick the USB drive → click Start.
2. It automatically sets up the partitions and makes the USB bootable on both Intel and Apple Silicon Macs.
3. If you’re in a rush or don’t like commands, WonderISO is hands down the fastest and safest way to burn ISO to USB on Mac.

(2) If you prefer using built-in macOS tools, do it manually with Terminal.

First, erase the USB using Disk Utility as MS-DOS (FAT) + GUID (Apple’s official guide: support.apple.com/guide/disk-utility).

Then open Terminal and run:

hdiutil mount /path/Windows10.iso
diskutil list
cp -R /Volumes/CCCOMA_X64FRE_EN-US_DV9/* /Volumes/WINUSB/
diskutil eject /Volumes/WINUSB/

This command-line way also burns ISO to USB on Mac, but make sure the ISO doesn’t have files larger than 4GB (FAT32 limit).

If it does, you’ll need to use the first method.

Either way, both work perfectly to burn ISO to USB on Mac and get your mom’s PC ready for a clean Windows 10 install.

You can definitely create a bootable Windows 10 USB using your Macs, even without Boot Camp. Since both are Macs (including the newer M1 and M3), the easiest way is to use Terminal with the diskutil and dd commands, or a free app called BalenaEtcher that works on macOS.

How to burn ISO to USB on mac via Terminal commands:

1. Download the Windows ISO.
2. Convert it to a format suitable for creating bootable media.
3. Use dd to burn ISO to USB.

On M1/M3 Macs, creating bootable Windows media directly for Intel-based PCs sometimes has compatibility quirks, but generally, the USB created with Etcher should work fine. After creating the USB, you might need to connect it to the PC, restart, and boot from USB (often by pressing F12, F10, or Esc during startup — check your PC’s boot menu).
