mex and C/C++ compiler error

I'm trying to setup the compliers for C/C++ code generation on MATLAB R2022a, to generate audio plugins to be used in DAWs.

I'm using a macOs Ventura 13.1 system, I installed Xcode version 14.2, but when i try to setup the code compiler with the commands

"mex -setup", "mex -setup C" or "mex -setup C++" I always get the following error message, the same I got before installing Xcode

this is what i get as output:

>> mex -setup

@DARIO BENVEGNÙ - from the above error message, the link for MAC seems to suggest that Xcode14.x is not yet supported. Can you install 13.x instead?
