I installed and activated Matlab on macOS Catalina but it's not opening

I downloaded, installed and activated Matlab in a Mac computer (Catalina).

I found a similar question which solve the problem on Windows.

So I tried to delete R2019b folder under the following path:

/Users/MyUser/Library/Application Support/MathWorks/MATLAB/

When I click Matlab icon on the docker, it regenerates R2019b folder and software still doesn't open.

What should I check for?

Thank you.

Try running MATLAB without the desktop environment.

Open a Terminal window (/Applications/Utilities/Terminal.app) and run the following command:

$MATLAB/bin/matlab -nodesktop

Where $MATLAB is the path to your MATLAB directory.

Since you are using MATLAB R2019b and if you have installed MATLAB in the default directory, the command will be:

/Applications/MATLAB_R2019b.app/bin/matlab -nodesktop

If MATLAB starts, it will start in the Terminal window itself.

The title of the Terminal window will change to say “MATLAB_maci64 -nodesktop.” From the Terminal window, run the command “desktop” to attempt to start the MATLAB desktop environment.

This will produce an error message which may help you to identify the problem. If you would like assistance in interpreting the error, please contact MathWorks support.
