Unable to upgrade VM from 26.5.2 to 26.6.2 due to personalization error

[kode54]

I cannot upgrade a VM from one release of macOS 26 to the latest, it throws a personalization error every time.

This is likely an Apple TSS authlisting error or a bug in macOS running on the host and/or guest, not a bug in VirtualBuddy. Please report this to Apple using Feedback Assistant.

Sorry, I didn't realize it was dependent on the host OS and firmware to grant permission. Apparently a bug in macOS 27 granting OTA updates for older VMs.

Alas, I can delete those VMs anyway, as I'm no longer doing dev work with Xcode 26.
