Hi,

To resolve this issue , delete the residual Xcode beta license agreement file at the following location:

/Library/Preferences/com.apple.dt.Xcode.plist

Afterwards, run the following command in the terminal to agree to the license for the full version of Xcode that is currently installed:

sudo xcodebuild -license accept

The compiler should now be found and the "mex" command should now work.

Hope it helps.
