Thanks Alexandre, I understand why I can’t use docker-machine, the Docker Machine doesn’t work the same way as before.
The Docker.app binary usually is under /Applications directory, but maybe not, and usually is more reliable the command line.
Open is nice if you have located the Docker.app binary, but with the docker-machine command you can check the status for the VM easily, and start/stop commands. Works like any Linux service. Now is a bit more tricky because I need to launch Docker.app with open and then check the status with the Docker API. Anyway, it’s not a problem.
Thanks.
