How to share compiled mex files as a verified apple developer?

I work for an educational institition that shares Matlab code with the general public. Some of the code we share are compiled mex files.

On mac, for a user to run a compiled mex file, they need to allow each file to run. Many of our scripts call multiple mex files and this get annoying for users.

Our institution has a apple developer account and we want to sign our code so that compiled code is trusted but do not know how to do this. Any help?

I don't recall such a dialog window when calling a compiled mex file from normal Matlab code. Is this a side-effect of packaging to a standalone executable?

If you don't get a response here, you may want to reach out to support directly, as the volunteers mainly answering the questions might not know.

Hello Rik,

Thank you for the response, I have contacted Matlab support. I am compiling code that is essentially a compiled library for other people to use. Mac requires compiled code to be notarized, I have learned, otherwise the user has to go into their device settings and allow each un-notatized compiled file to run individually. This is very tedous in our case, otherwise I wouldn't worry about it.

Matlab support provided me with the following link:

https://www.mathworks.com/matlabcentral/answers/726743-how-can-i-sign-and-notarize-my-compiled-application-to-conform-with-apple-s-notarization-requirement

which appears to be a good start, but I am having issues signing the app. When I sign my code, I am getting:

Warning: unable to build chain to self-signed root for signer "<my signing name>"

We will see if I am able to get things sorted out. I am on the right track with the above link, but still having difficulties.

I'll try and keep people posted in case someone else has this issue.
