There is no uninstall on OS X, so you simply stop the services and then install the newer qube packages. No data is lost during the uninstall/re-install.

You will need to stop the qube supervisor before you install over top of the older version. Since the supervisor is under
launchctl control, so it can be stopped with this command:
sudo launchctl stop com.pipelinefx.supervisor
