Mac upgrade to 10.15.3

Post by mjohannes » Mon Feb 10, 2020 9:15 am

I upgrade my mac mini to 10.15.3 Saturday morning. Everything worked well prior to this upgrade. Once I upgraded, I can no longer run HD over the air channels. When I click on those channels, they are black for about 30 seconds to 1 minute, then they show some form of the channel but it is blocky and the audio doesn't come through. This continues to degrade until it is completely stopped. None HD channels work fine. I have a Macbook pro running 10.15.3 and it works just fine.
Is there any information on what could have changed that would cause this? Not sure how to proceed. Considering rolling Mac OS back to 10.14, but that isn't the most desirable choice for me. Suggestions?

Does VLC work on that Mac? Go into the Playlist > Universal Plug'n'Play, double click on the HDHomeRun, then Channels, then a channel, and see if it plays or has the same issue.

Is the Mac wired or wireless?

When this happens, is it only the HDHomeRun app that won't connect? For example, will Safari load any websites from the internet? Are you connected via wifi or wired ethernet?

All other functions that I have tried work...Safari, Apple TV (in fact that is how I am watching the HD channels...I open either my iPad or MacBook pro and airplay the channel to my apple tv which is hooked up to the TV also) I am wireless... but so are the other devices that work.

I just downloaded the latest version of VLC and it doesn't show HD Connect under UPNP. I am not sure how to configure VLC to see the HD Connect stream

If you go to http://my.hdhomerun.com/ and click on the device ID for your HDHomeRun, it will show its IP address in your browser's address bar. You can tune channels directly in VLC using a URL like this:

http://ip.address:5003/auto/vx.y

where ip.address is the IP address from the browser and x.y is the channel number you want to watch. So it would end up being something like:

http://192.168.1.105:5004/auto/v2.1

had to use 5004 (not 5003). I get the same behavior. The HD channel is stop and go, non-HD play just fine. So what does this indicate? Any suggestions on how to proceed?

The symptoms are consistent with poor network performance on the Mac. SD channels works because they're transmitted at much lower data rates than HD channels. I'd guess it's probably a driver problem related to the network interface in that specific Mac model. Roll back to 10.14 and either keep it there or hope Apple fixes it in a future 10.15 update.
