title: ILOG CPLEX Optimization Studio not working on MacOS
body: <p>I tried to use ILOG CPLEX Optimization Studio on my MacBook. The installation worked fine, but after startup the application is literally unusable.
  I created a empty Project, when I click any file I get a java.lang.NullPointerException. In the preferences, when I try to access any page I just get a error that the current page has wrong values.
  Any Idea how to fix that. My colleague has exactly the same problems. I have currently installed 12.10, but already tried with 12.9 which shows the same errors.</p>
  <p>Edit: Tried it on macOS Catalina and Big Sur with the same behaviour</p>
