  1. Hi, I am running Mac OS X Mojave and connection to eduroam does not work. But there is at the moment no CAT installer for Moiave available. Will there be one in the future? thank  you!

  2. Please use the installer for "Apple macOS High Sierra" instead.

    We are in the transition to CAT 2.0, which will then again include native installers for the latest versions of Apple operating systems.

    1. Thanks, I give it a try.
