I've installed Houdini on my Mac, chosen an Apprentice License, and everything was working fine. After a month I started having issues with the license and I couldn't get it working, so just uninstalled Houdini through the provided uninstaller. When I installed it again, it would successfully install another Apprentice License but gets stuck at the splash screen during startup.

The exact same happened on another Mac machine. I tried to uninstall and re-install many times with no luck. I've then formatted one machine and finally got it working, but just for another month, then same story again.

Is there a way to completely wipe an Houdini installation from a Mac so if this happens I don't have to format my laptop?
