I m trying to install some drivers, (Line6 / Digidesign nd Zoom ) . These drivers (all latest versions that works with Sierra) are not working and my devices (mainly audio units) are obviously not recognised . I read everywhere that the solution is goin to System Preference then Security nd Privacy and then on General window click on Allow button . The problem is that There isn't that button . I attach the pic to show it .
The allow button dynamically appears when you try to install and use for example 3rd party kernel extensions.
Re-run the installer for the drivers for the hardware, and revisit Security & Privacy in System Preferences. It should show up then.
