P.s Balena Etcher does not support Windows OS. You can still use this app for creating bootable Windows USB on Catalina and Mojave as far as I know. However, this feature is removed from Boot Camp app on macOS Big Sur. It is a built-in free app shipped with macOS by default. If you are using an old version of Windows 10 ISO, then Boot Camp Assistant can help you get this done easily. Also, this app works on latest Big Sur and M1 Mac as just tested it on a M1 MacBook Air with macOS Big Sur 11.5. It automatically splits the large ISO file into small parts so the Windows installation files can be sit on a FAT32 partition, which is the only working file system supported by Mac for Windows install. If you are using a newer Windows 10 ISO (after version 201809), then UUByte ISO Editor is the best app for creating a bootable USB on Mac. I managed to create several bootable Windows 10 USBs on Mac (Mojave, Catalina and Big Sur) in recent years. The highlight of this software is that it can automatically process ISO files larger than 4GB. I also tried other alternative tools like SYSGeeker WonderISO, UNetbootin and UUByte ISO Editor, they're really great softwares and each has its own merit. PS: This method is a bit difficult and error-prone and is not recommended if you are a novice. Wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim /Volumes/WIN10/sources/install.swm 4000 Finally enter the command this command to end the process: Rsync -avh -progress -exclude=sources/install.wim /Volumes/CCCOMA_X64FRE_EN-US_DV9/ /Volumes/WINDOWS10ĭon't forgot to install the Homebrew. Copy all files except install.wim to the USB drive by using the following command prompt. If it's more than 4 GB, you'll need to split the file. So, I've tried Terminal to create a bootable USB on macOS. The problem is that on MacOS that format restricts individual files from being larger than 4gb, and the install.wim file in the Windows 10 iso must be more than 4 G.Įtcher doens't seem to be able to process the ISO file larger than 4 GB. And can quickly complete tasks without any technical requirements.

UUbyte iSO Editor is a good choice for computer novices. The whole process won't take a long time. Just download and install this software on your Mac and run it. Suppose you are not interested in the above software. Generally speaking, the task is OK completed in 15 minutes. iso file in UNetbottin and burn it to the USB flash drive. If you have installed Windows iSO files on your Mac, try UNetbottin, plug in the USB on Mac, and launch the Disk Utility option. But if you are a computer novice or are not know much about CMD, please find another way. If you are good at CMD, it is possible to use CMD to create Windows 10 bootable USB on a Mac in a virtual machine. How about the boot camp Assistant? Although it does not work sometimes, as a multi-boot creation utility, it can create a Windows 10 bootable USB on your Mac.
