Mex on macos crashes

Is anyone having troubles in compiling mex files in R2023a (silicon native)?. I have old mex functions that compile fine in windows. In MacOs Sonoma they compile but then MATLAB crashes at runtime.

I see that the official documentation states that mex compiling is supported for XCode 14.x, but on Sonoma you can't install anything except from 15.x

Hello Simone,

I understand that you are encountering issues with compiling Mex files in MATLAB R2023a on macOS Sonoma, particularly related to compatibility with Xcode versions and potential runtime crashes.

Please refer the following MathWorks Documentation to verify compatibility: https://www.mathworks.com/help/matlab/ref/mex.html?#btw3m9i-4
