Hello everyone,
my Matlab just recently stopped launching when I click on the symbol. I also tried opening the program from the applications folder and from "show packages contents" and it doesn't open. So what happens is that when I click on the MATLAB symbol it seems to open and then just stops, so basicly does not respond at all.
Matlab used to work perfectly fine until yesterday. I just recently updated the new version of R2019b for Mac OS X. One critical point could be that I use OS X Catalina and I again failed to stop automatic updates, so one reason could be that my Mac updated to version 10.15.4 (19E266). I don't know how I missed to cancel automatic updates after that great Catalina disaster that made half of the programs not work any more.
Does anybody have an idea of what I could do?
Thanks a lot!
Florian

Thank you. After the problem appeared, I started Matlab using the terminal and then installed the 2020 version which works perfectly fine.
