Matlab triggeres sandboxd in macOs

Running matlab 2021b on MacOs 11.6 (Big Sur) on an intel i7 macbook pro and sandboxd appears frequently making matlab extremely slow. Is there a fix for this as the only short term solution is killing sandboxd and that does not seem like a long term viable solution.

Hi,

This is a known issue and our teams are working on it. As a workaround you can follow the below steps:

To open MATLAB from the terminal, open a Terminal window (/Applications/Utilities/Terminal.app) and run the following command:

$MATLAB/bin/matlab

Where $MATLAB is the path to your MATLAB directory. For example, if you are using MATLAB R2021b and have installed MATLAB in the default directory, the command will be:

/Applications/MATLAB_R2021b.app/bin/matlab

This workaround doesn't work for me. My Matlab is freezing very often, sometimes with and sometimes without sandboxd running high CPU.

That solved it for me in a good way.
