It is typically removable and much smaller than an optical disc. rwxrwxrwx 1 alter staff 1.5G 26 Nov 01:08 /Volumes/WINDOWS10/sources/install2.A Universal Serial Bus or USB Drive, also known as a flash drive is a portable data storage device that includes a memory which includes a USB interface. Then call after (clearly, replacing the volume folder names to yours): wimlib-imagex split /Volumes/CPRA_X64FREV_ES-MX_DV5/sources/install.wim /Volumes/WINDOWS10/sources/install.swm 3000Īnd now you will have two or more files with a swm extension instead of wim, where they won't be larger than 3GB -rwxrwxrwx 1 alter staff 2.9G 26 Nov 01:03 /Volumes/WINDOWS10/sources/install.swm

So, using Homebrew install them with: brew install wimlib In this case, you will need to slipt it and copy it with the Windows Imaging libraries. That's because the install.wim file is larger than 4GB, too large for your just created FAT32 partition in your USB stick (back in the day I originally posted this answer, probably the file wasn't that big).

Look closely the copied files, as if you see a message like: cp: /Volumes/CPRA_X64FREV_ES-MX_DV5/sources/install.wim: File too large

So finally copy all the files from the mounted iso to your usb drive: cp -rpv /Volumes/CPRA_X64FREV_ES-MX_DV5/* /Volumes/WINDOWS10 The command will return the location of the mounted iso /dev/disk3 /Volumes/CPRA_X64FREV_ES-MX_DV5 Then mount your image with: hdiutil mount your_windows_10_image.iso Please double check this step, or you could delete all data in another drive. Where disk2 is the usb drive id known in the prior command and 'WINDOWS10' is the volume label (to be used later). Knowing this, format your usb drive with: diskutil eraseDisk MS-DOS 'WINDOWS10' MBR disk2 You'll see something like: /dev/disk0 (internal):Ģ: Apple_APFS Container disk1 500.0 GB disk0s2Ġ: APFS Container Scheme - +500.0 GB disk1ġ: APFS Volume Macintosh HD 185.7 GB disk1s1įor my case, the usb drive was /dev/disk2. Start connecting your usb drive and type diskutil list to display all connected drives. This can be done via console for Windows 10/11 iso images (Not sure about 8/7, but leave any comment if it worked for you).
