There is no installation required to get the HTS running on MacOS. All you have to do is download the package and unpack the OSX version to /Applications/.
When you start the HTS, a script will run in order to check if you have Mono Framework installed. If this is missing it will advise to install it first.
When you start HTS it may take a few moments to initialize, this is normal. After a few moments, your browser will open to http://127.0.0.1:8090/.
It is rare, but there might be a small conflict with your browser that prevents it from opening automatically. If after a few moment the browser doesn't open automatically, manually open the browser and navigate to the URL: http://127.0.0.1:8090/
