MATLAB was launching without issue on my Mac until updating to MacOS Sequoia 15.1. When launching MATLAB I see the following error; The application “Dock” does not have permission to open “(null)”.

This error affects the Intel versions of MATLAB R2024a and older releases on macOS 15.1.
The Intel version of MATLAB R2024b is not affected, and the "Native Apple Silicon" versions of MATLAB (R2023b and newer) are not affected.
If you have an Intel Mac, install the Intel version of MATLAB R2024b using the installer from mathworks.com/downloads
If you have an Apple Silicon Mac, consider uninstalling MATLAB then install the Native Apple Silicon version of R2024b instead by using the installer from mathworks.com/downloads
For more information, see:
MATLAB on Apple Silicon Macs
As a workaround to run Intel versions of MATLAB R2024a and older on macOS 15.1 or 15.2, you may be able to launch MATLAB from terminal like this:
/Applications/MATLAB_R20XXx.app/bin/matlab -maci64
Note: The R20XXx must be edited to correspond to your install release of MATLAB, e.g. R2021b.
This error may be resolved in a future update to macOS 15.
