I'm getting the same error (Unhandled Exception, System.UnauthorizedAccess to a path in /private/var/folders/<apparently random uuid>), running on macOS Sierra and mono version 5.0.1.1. Did you have any luck? Same here. macOS Sierra 10.12.5 (16F73), mono 5.0.1.1. Actually solved it by accessing the toolkit before clicking OK on the other window. How did you do that? When I tried clicking on the Toolkit window nothing happened.
Hi all, When I open Toolkit on my Mac I get this message: "Unhandled Exception catched!" When I click OK, it then closes the app. Both Toolkit and Mono have installed properly, so I am not sure what the issue is. Thanks
