Double click a working license and then HyperDock is registered until reboot.
Here's the magic:
- Use terminal to change the filename HyperDock.prefpane into HyperDock (the file is in ~/Library/PreferencePanes/ or /Library/PreferencePanes/.
- Open preference->Security->Firewall and enable it, in Advanced settings, add an item, and navigate to ~/Library/PreferencePanes/HyperDock/Contents/Resources and select Hyper Dock Helper, and disable it from connecting to the internet.
- Use terminal to change the filename back from HyperDock into HyperDock.prefpane.
Another method might be editing hosts. Somebody may want to try it.
