Solved Windows 11 on UTM on Apple Silicon still on 21H2—how to upgrade

Baeolophus · Nov 13, 2023

I just discovered that my UTM VM on Apple Silicon is still running Windows 11 21H2. How do I upgrade to 22H2 or 23H2? There is noting in Settings → Windows Update that would indicate how to do that.

You can download the 23H2 ISO image from Microsoft and mount the ISO image double-click setup.exe to perform in-place upgrade.

Download Windows 11

It turns out that Installation Assistant does not work on a VM or at least an ARM VM. I’ll have to use the Media Creation Tool, instead.

An error occurred while using the Media Creation Tool. Twice. Must not work in my case.

Download the arm iso from uupdump

There is no need to use the UUP Dump Site(s), the UTM developers have produced their own native macOS Windows 11 download tool (using similar ISO creation methods to those used by Parallels and VMWare) see CrystalFetch on GitHub

I have used it myself and it is much quicker and easier than using the UUP Dump procedure which has to be used in Windows.
