Go to /Applications/ right click on your MATLAB app select Show Package Contents look in the bin folder. Its the first item in the bin folder: activate_matlab.sh

Is it reasonable to put root as the Licensed End Use?

Walter Roberson 2022-7-13

@Pol Adillon

Using root as the licensed end user is not usually a good idea. That would force people to sudo in order to run MATLAB, and the resulting session would have write access to nearly everything on the system

The message sounds like you have to run the Activation client to reactivate your license. Did you try this already? If you have no success, the Mathworks support team can and will help you, while the power of the forum ist limited for such questions.
