Why doesn't MATLAB 2019b open on macOS Mojave?

When I click on MATLAB 2019b in the applications folder or in the launchpad, nothing happens. There is no pop-up window, no error message and absolutely no indication as to what is happening. There is a dot showing up next to the application in the dock indicating that it is running. But this dot goes away after 3 seconds, and the application never opens.

I am facing the same issue after updating my mac to ver : 10.15.1 Catalina

I have the same problem. Just Installed it and try to open but nothing happens. Even the icon dosent jump on the dock.

Note that problems with Catalina are not necessarily the same cause as the same symptom for Mojave :(

However for both, see https://www.mathworks.com/matlabcentral/answers/480796-not-responding-on-startup-macos-mojave#answer_398840 which a third party developer tracked down a problem.

Open up Finder and then head to Matlab in the applications folder.

Right click and select "Show Package Contents."

Open "activation.app"

Finish the activation and it should work from there. Thats how it worked for me!

@Christpher Horne, thanks that worked for me also

Hello, you might have solved the issue. But I am posting my solution incase someone else needs.

I tried many different ways of this issue and finally found the following solution to this:

On MAC go to, /Applications/MATLAB_R2019a/bin/maci64/update_installer

Update 8 was installed and then it asked for Activation. Now the MATLAB works fine.
