Installing Matlab 2019b on Mac OS Catalina

I installed MATLAB 2019b on my Mac OS Catalina yesterday, but it just starts for one second and then crashes.

How can I get it running?

I removed "Magnet".

I restarted everything.

My MacBook Pro is from late 2015.

Try running Matlab from the terminal using the flag '-noopengl'. If it still doesn't run then update your graphic drivers and try launching Matlab normally.

I do not have the permission to do so - IDK why.

zsh: permission denied: /Applications/MATLAB_R2019b.app

Additionally it is creating a java fatal error:

# A fatal error has been detected by the Java Runtime Environment:

I already update java and testet ulimit -cunlimeted etc. but still do not know, what's going wrong

Launch matlab from the terminal using the flag -nojvm. This should launch matlab without any graphical windows. If this launch is successful that means the issue is with your JRE in which case you should update it. The below answers might help you with that:

$MATLAB/bin/matlab -nojvm

Where $MATLAB is the path to your MATLAB directory.
