If you are trying to watch a live stream from Arcus on a Mac computer in Chrome, you will need to be sure that the Adobe Flash browser plugin is updated and activated in the browser. Each time Chrome updates, however, you may need to repeat this process. Here are the steps to do this:
1. Click on Settings in the Chrome browser menu.
2. Type "Flash" into the search at the top to find the Flash settings.
3. Make sure that the setting is set to "Allow sites to run Flash".
