Aseba/VPL not starting when trying to use with simulator on Mac 10.13.3.

Created by: tiemes

On Mac 10.13.3 with Aseba 1.6.0: If trying to start Aseba Studio with a simulated Thymio it freezes without opening GUI. I can run Playground and select a file. I see the selected environment but get error messages in the print below. (see screenshot). On top of the Mac screen the "VPL" oder "Aesba Studio" (tried both) name appears but the cursor keeps rotating and no window opens.
