Or download one of the original versions of Windows 10 (assuming you can find one from a trusted source), use etcher with that, then upgraded to the latest 1909 or whatever version you are looking for. That is what I use for work and it has never failed (the VM that is - both Rufus and WMCT should work fine).įollow that advice and you’ll be up and running. Your best solution is to either boot to Linux and use tools available there to write the iso to USB, or load a VM (VirtualBox is free - but a parallels trial would work much better) with Windows 10 and use that to create a USB drive with Rufus or the actual Microsoft Media Creation tool.

You will not get this to work with mac native tools. Also, changes to Bootcamp removed writing to an external USB drive and now sets up Bootcamp using a RAM disk in a temporary drive partition. To download this Mac version Of Rufus, simply click on the download button below: The freeware Rufus 3.5 is designed to quickly and easily format and boot. The developer of Rufus is also aware and was able to hack together a solution that requires disabling secure boot while installing.Īnyways, Etcher (or any other software/terminal DD on Mac) follows protocols and errors out while trying to write a file larger than the file system allows. The Microsoft tool is already aware and works magic when writing an iso to let this happen. The WIM files are larger than what the FAT filesystem supports. You are experiencing issues due to how Microsoft changed their installation methods as of Windows 10 v 1803.
