when I try to link docker and docker-machine I get a message saying is already linked

Warning: Already linked: /usr/local/Cellar/docker-machine/0.12.2
To relink: brew unlink docker-machine && brew link docker-machine

Have you attempted sudo chown root:wheel /usr/local/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve manually? Have you confirmed that /usr/local/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve exists?

This is the output of the sudo command
