It appears there are some issues with the Wowza Streaming Engine running OS X El Capitan. I took a working OS X Yosemite installation with the latest Wowza Streaming Engine 4.3.0, build 16025 and ran into issues where the web interface would display and incoming/outgoing connections and streaming wasn't working. I didn't have time to troubleshoot and reverted back to the OS X Yosemite installation, but I was curious if Wowza Media Systems as done any testing with their Wowza Streaming Engine on OS X El Capitan and could state if it is or isn't compatible?
