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.
Stopping the Qube Worker
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.worker
Installing the Qube Worker
The only condition is that the Qube-core is installed first. You can install all other Qube components in any order.
The most common order is
- install the Qube-core
- install the Qube worker
- install the QubeGUI
