Sketchup crashes using Maxwell for Sketchup

Hello, I have a 2018 scetchup pro and maxwell 4 installed. My Mac is constantly crashing when I add materials etc. In ny scetchup it says that my Maxwell Render is not signed. I have done the unrestricted mark in my extensions so that should not be a problem. Do any of you know if that’s why my scetchup is crashing? Since I installed the Cataline update its a lot of problems with the rest of my programs as well. I really appreciate if anyone can help on the issue. Best Eilev

For a start I would look at program compatibility. Is the Maxwell version correct for the OS and SketchUp version. The lack of a signature is not an issue.
