I recently updated my Mac to Mojave.

I have several apps (e.g. Dropbox, Backblaze, Stay) that require specific permissions that can be granted via System Preferences > Security & Privacy > Privacy.

Since the update to Mojave, I can no longer add any apps to the mentioned Preferences pane. For example, when going to the "Accessibility pane ("Allow the apps below to control your computer") and adding an app via the `+` button or by drag & drop from the Finder, the action is simply ignored and the list stays empty.

Any idea to work around it?
