Do you have any Accessibility programs set in System Preferences? If so then experiment with turning them off.

Also if you have Magnet or similar window manager running, experiment with turning that off.

[Emin Oskay]

This problem started occuring after I upgraded to the new OS Catalina. Matlab 2019b always kept freezing when I launched it and the older versions of Matlab like 2019a was very laggy. Not sure if there was I problem during the process of the update from Mojave to Catalina but all of my friends that owns a macbook had no problems with matlab.

I solved the problem just by downgrading from Catalina back to Mojave and haven't have a problem since that then. A bit scared to upgrade back to Catalina but going try it again when exams are over.

Hi Emin,

Actually, I have the same problem like yours !

I have no idea whether it does super work with Mojave !
