That is not the way it is working on macOS (nor the way it should work at all).

I assume you mean being user and in the multipass group is not the way you want it.

How should it work then?

[rcarmo]

I should not need to add myself to the Multipass group nor need any under the hood configuration changes. It should just work for non-admins, although some things like updating should require an admin password.
