We're trying to create 26.4 beta and RC VMs on 15.x and 26.3 host OS' without success. We see

Tue Mar 17 17:27:36 40 anka.log (install) 45803: failed to install macOS: Error Domain=VZErrorDomain Code=10006 "Installation requires a software update." UserInfo={NSLocalizedFailure=A software update is required to complete the installation., NSLocalizedFailureReason=Installation requires a software update.}

Yet, if we create it the same way on 26.4 beta host OS, it works.

We've tried the usual tricks of installing latest Xcode and preparing it (accepting license, etc). But, they don't work on 26.3 and 15.x.

What's the trick to get the creation of 26.4 to work on <= 26.3 host OS?

Thanks for filing that.

is it possible that your work Mac has access to an internal software update server … ?

It’s certainly possible, but I usually keep a tight reign on this Mac to prevent that sort of thing.

Anyway, based on the fact that multiple folks on this thread are reporting this issue, I think it warrants investigation by the Virtualization team. If you’re hitting this, please file a bug with the details and then post the bug number here.

Thanks for all the updates. I’m researching this more and I hope to have another update in the next day or two.

I confirm that installing the Xcode.app/Contents/Resources/Packages/MobileDevice.pkg package of Xcode 26.4 (with the UI) on macOS 15.7.5 fix the installation problem of macOS 26.4 in VirtualBuddy.
