If you want to avoid going through all that trouble just to create a Windows 10 USB installer on Mac, the best alternative is to use a third-party application that does all the heavy lifting for you. Even worse, you may end up breaking your Mac if you run a wrong command because you’ll be doing all of this in administrator mode. What you’ll end up doing is reading dozens of forum posts trying to find the exact solution to the problem you’re facing… and there’s no guarantee it will work. Unless you have some experience using command-line tools, this is going to be a painstaking process where anything could go wrong and there’s no customer support to bail you out. However, that involves using Homebrew on your Mac. This is the reason why we have to cut install.wim into small pieces that is less than 4GB in order to sit on a FAT32 partition.įor that, you need an open-source utility like wimlib. Tips: NTFS is not supported by Mac natively so you can not write files to a NTFS partition on Mac.
