At a first glance this sounds exciting: We use a lot of different versions of macOS and Xcode for building our apps. We have one dedicated Mac, and about 5 VMs on a second Mac that we use for building our software. Keeping everything up to date is a pain. So if we could just rent Mac VMs that would be nice. But this is pretty much useless. You get only a single machine for a really high price. Theoretically I could run VMWare on the rented machine, to run multiple virtual copies of macOS, but then I'd be doing all the maintenance that I don't want to do.
