Etcher​ for Mac not working. Any good alternative to Etcher on macOS?

This is a quite challenging task on Apple Silicon Mac due to the missing support of NTFS writing on Mac. Here are three easy ways to help you create windows 11 bootable usb on mac if Etcher for Mac does not work. For tech newbie, try the first solution. For advanced users, go with the latest command line approach.

Method 1: ISOKit app

ISOKit is a lightweight tool designed to create bootable USB drives from ISO files on macOS. It is simple to use and works well for creating Windows or Linux installation media.

Steps:

1. Download and install ISOKiton your Mac.
2. Insert a USB flash drive (8GB or larger recommended).
3. Launch ISOKit and choose the ISO file you want to burn.
4. Select the connected USB drive as the target disk.
5. Click Start to begin creating the bootable USB.

Why it’s good

• Very easy interface
• Works with most Windows and Linux ISO files
• No command-line knowledge required

Method 2: BootCamp

Another option is Boot Camp Assistant, which is already included in macOS. Although it is mainly designed to install Windows on Intel Macs, it can also create a Windows installation USB.

Steps:

1. Open Boot Camp Assistant from Applications → Utilities.
2. Choose the option Create a Windows install disk.
3. Select your Windows ISO file.
4. Insert a USB flash drive and select it as the destination.
5. Boot Camp will automatically format the drive and copy installation files.

Advantages

1. Built into macOS
2. Stable and reliable for Windows installers
3. No extra software needed

Limitations

• Only works for Windows installation media
• Not available on Apple Silicon Macs

Method 3: Command Line with Wimlib

The wimlib-imagex utility can split a large install.wim file into smaller .swm parts so they fit on a FAT32 USB drive. This avoids the common 4GB file size limitation that often causes problems when making Windows installation USBs manually on macOS.

Although this method requires using Terminal, it is quite reliable once the commands are executed correctly. Many advanced users prefer this approach when graphical tools like Etcher fail.

Install wimlib using Homebrew:

brew install wimlib

Mount the Windows ISO file:

hdiutil mount Win11.iso

Format the USB drive as FAT32:

diskutil eraseDisk MS-DOS WINUSB MBR /dev/diskX

Copy all files from the mounted ISO to the USB drive except install.wim.

Split the WIM file into smaller parts:

wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim /Volumes/WINUSB/sources/install.swm 3800

Wait for the process to complete and eject the USB drive.

Pros

• Very powerful and flexible
• Works without additional software
• Supports many ISO images

Cons

• Command-line knowledge required
• Wrong disk selection can erase data

Your tag line says that you have an Apple-Silicon-based Mac: a 24" iMac.

So exactly what is your goal in creating a bootable USB drive with a Windows 11 installer on it? Apple Silicon CPUs speak a different machine code instruction set than Intel and AMD CPUs, so you can't run Intel-based versions of Windows at all. As for Windows 11 for ARM, while you can run that inside of a virtual machine (Parallels Desktop or VMWare Fusion Pro), you. cannot run it as the main OS. Neither Apple nor Microsoft Support that, and there is no Boot Camp /Assistant for Apple Silicon Macs.

Etcher doesn't support making a bootable Windows USB stick. It is mainly used for creating bootable Linux installers.

There is no need to use any third party software at all to make a bootable Windows USB installer from an ISO installer. It can all be easily accomplished with macOS and the Windows installer itself.

Here is a post with very clear & detailed instructions (the pictures of the Windows installer screens may be different depending on the exact version & build of Windows you have, but the steps will still work):
