Help! On my Mac Mini (Mid 2011) running the latest version of High Sierra I can't stream any videos on Safari or Chrome. I can't watch things on Amazon, Netflix, or youtube. I run the mac mini with my projector as my media server. I have tried everything I could find running a search for how to fix streaming problems. Among other things, I have tried: (1) Enabling pop-ups. (2) Clearing my cache (3) Disconnecting my projector and trying to watch videos using screen sharing. (4) Disconnecting screen sharing and trying to watch videos using my projector. (5) Disabling plug ins. I have restarted my computer before trying each of these. I can't figure it out! Any help greatly appreciated.
