Filed feedback, looks like a bug in the upgrader setting up the install volume.

Any update on the new Beta 6? I don't want to waste my time.

Not sure that there are plugins to support it. You could try the appropriately titled Lazarus IDE - https://www.lazarus-ide.org/

Yes. To sign and notarize for other users you need a developer account.

This is a key requirement to make macOS Guest virtualization useful.

Expanding Xcode on the native platform and then copying it to the VM ddid not solve the issue.

Who thought this was a good idea?

Kevin, Thanks for getting back to me on this. I hope Apple will see the value of adding that capability. -- Harald

Thank you. This was both 261 and 26.2beta. The naming issue was an error. I was able to get scripts to work. I still wish I had found a way to delete a behavior. But just reassigning it is good enough.
