MATLAB will not open in MacOS Sequoia15.1

When attempting to open MATLAB_R2023a.app, MacOS 15.1 shows the message: The application “Dock” does not have permission to open “(null).” or the message: The application “Finder” does not have permission to open “(null).” Do I need to update MATLAB so that it will run on Apple M3 silcon? Or is this problem due to the MacOS update?

Yes, it is a problem caused by the Sequoia Mac OS update. There are 3 known options for solving the problem:

1. Upgrade to a 2024 version of Matlab (preferable in most cases).
2. Run Matlab directly from the Terminal by typing the address of the matlab file into the terminal, which for you is probably /Applications/MATLAB_R2023a.app/bin/matlab
3. Run Matlab from the Finder, using the following steps: (a) in the Finder, right-click or ctrl-click on the Matlab icon, which is probably in the Applications folder, (b) in the menu that comes up, click on "Show package contents", (c) in the folder that opens up, double-click on the "bin" folder, (d) in that folder, double-click on "matlab". This method is essentially equivalent to Method 2, in that it runs Matlab via the Terminal.

In particular, R2024b is needed.

If you don't get an answer here today, then I suggest you call tech support tomorrow for installation support.

Do exactly what it says to do in the FAQ:
