I am glad you have got it working, but the permissions aspect is of concern. We had so many permissions problems reported when users used third-party tools such as UnArchiver to unzip the distribution, that we have had to advise that users only use the native Apple utility (when you just double-click on the zipfile). I have yet to update to Mojave (I only have the one machine, and like to wait some weeks in case problems are reported). So it will be very helpful to know if you used the Apple utility, or a third-party tool.
