CPLEX 20.1 not Working on macOS Big Sur

    Hello All,

    I have some students that are having issues running the CPLEX Optimization Studio 20.1 on macOS Big Sur. See the error below. I tried to follow these instructions here for macOS Catalina but they seem not to work for Big Sur. Does anyone know the solution for this issue? Any suggestions are appreciated. Thank you!
