I think you forgot how this thread got started:

> If you’re on macOS, then Orbstack is a nice alternative to Docker Desktop

We’re talking about running OCI (“Docker compatible”) images. The page you just linked to makes it apparent that you are talking about something orthogonal: OrbStack’s “machines” feature (https://docs.orbstack.dev/machines/).

The original topic is that OrbStack’s support for Docker containers is fast (implied: faster than Docker for Desktop), which cannot be explained by the lack of a VM, as both use a Linux VM to run one or more Docker containers.
