No AP after XP12 Update

[Noel Murray]

After my last routine update of xp12, the products I have bought from x aviation no longer work (no autopilot) installed on my MAC. (Islander BT and Cessna Skyhawk). The AP is switching on and looks active but it will not lock on to either GPS or VOR/ILS tracks, nor does it control rate of climb when VS is selected. All of my other aircraft (LR and third party) work fine. Can you give me advice on how to resolve this issue.

Are you using the X-Plane 12 beta?

AP seems to be working in the latest beta, 12.06b6.
