in Terminal.
Once the download completed successfully, I launched the installer and followed the on-screen instructions. When the VM rebooted into OpenCore, I selected the macOS Installer entry and let the installation proceed.
The installer initially showed com.apple.BuildInfo.preflight.error 21, but after rebooting and selecting my usual macOS disk, the update had completed successfully.
The system is now running Tahoe 26.6, and so far everything is working fine.
Thank you.
