 The Coverity Scan addon doesn't work on macOS versions with the SIP feature enabled i.e. on macOS El Capitan (10.11) and higher. Specifically on Travis CI, it currently only works on our Xcode 6.4 image (i.e. with `osx_image: xcode6.4`). However, it's possible to make it work with custom scripts or commands. Please reach out to [[email protected]](mailto:[email protected]) to learn how.
