Matlab Catalina wont open then says not responding but does not show up as running to force quit.. computer lags/restart.

After installing catalina 2019a and b, the b in admin profile..... neither will open and if i get aggressive in clicking on the icon it says cannot open because matlab is not responding.......

Did you end up finding a solution? Experiencing the same issue.

Answer 1

[Sai Sri Pathuri]

Currently there is a bug which stops MATLAB License Manager Error message windows from appearing. To find what error is causing MATLAB not to function launch MATLAB from a terminal window using a command such as the one below.

/Applications/MATLAB_R2019b.app/bin/matlab

This should output the License Manager Error, which you can use to determine the root of the issue.

I'm experiencing the same problem. The

/Applications/MATLAB_R2019b.app/bin/matlab

command does not output anything...

Thanks

that is the same for me no response! i will try to open a ticket

[Andrew Lipich]

/Applications/MATLAB_R2019b.app/bin/matlab

does not output anything in terminal

Same problem for me; also double clicking on a .m file will not open Matlab.

Matlab only opens if I type /Applications/MATLAB_R2019b.app/bin/matlab in a terminal, but it does not output anything regarding the error.
