For those running macOS Sonoma in virtual machines for testing, I found a workaround to enable beta updates within the guest operating system: https://github.com/insidegui/VirtualBuddy/discussions/194#discussioncomment-6406771
Upgrade to Sonoma Beta 3 within VirtualBuddy? · insidegui/VirtualBuddy · Discussion #194

I can't seem to figure out how to upgrade a working Sonoma install in VirtualBuddy rather than downloading a full restore image and starting from scratch. Am I missing something simple?

@_inside whats the best way of using macOS VMs on Intel Macs (hackintosh here)? still VMWare/VirtualBox? thanks!
@_inside The catalog URL continues to become more hilarious over time.
@_inside @siracusa Reason #12,954 on why VMs need to support Apple IDs.
@chockenberry @siracusa Yup. We've been able to log in using the Simulator for a long time, I don't see why VMs can't use a similar approach.

@_inside @chockenberry @siracusa I expect they’re paravirtualize the login soon enough
@_inside I downloaded the full InstallAssistant.pkg and ran it inside the VM and it was able to update. I used Mr. Macintosh’s helpful links to get the download: https://mrmacintosh.com/macos-sonoma-full-installer-database-download-directly-from-apple/

@_inside how does anyone do this at all, without being able to log into their Apple ID?
@_inside thank you! Aside from this limitation, VirtualBuddy has been a joy to use. Hopefully Apple doesn’t *fix* it
