"Your HDHomeRun DVR wasn't found" error MacOS 27 (& 26.7)

[dprisoner]

I upgraded my M1 MacMini with the DVR on it to macOS 27 on Monday, and the applications now gives me a "Your HDHomeRun DVR wasn't found" error in the recorded tab. I took another M1 MacMini I had laying around, gave it a fresh install of macOS 27 and still same problem. I then did a wipe and installed macOS 26.7 and the problem persists.

I've tried both the 20260629 installer and 20260909beta installers.

What is the device ID for your HDHomeRun?

I am also seeing this exact issue after "upgrading" to Mac OSX 27. My HDHomerun tuner device ID is 10A8AED0 FLEX 4K. I have an older tuner as well, but that one is currently offline...

Works fine for me on 26.7. I will test 27 later tonight.

Did you get prompted to "Allow "HDHomeRun" to find devices on local networks"?
Does the HDHomeRun.app show enabled in Privacy & Security > Local Network?

I had the HDHomeRun enabled in Local Network, since I've had to do that some years ago if my memory is correct.

Interestingly, HDHomeRun shows up twice in "Local Network" for some reason??? Toggling either of the HDHomeRun items toggles the other as well.

I can ping the HDHomerun from my Mac, and my Mac is definitely visible on my local network.

I have rebooted the Mac and the HDHomeRun a couple of times each, just in case that would make a difference.

Recording to this Mac Mini was working fine under OS 26.7, for what it's worth.

What is the device ID for your HDHomeRun?

Are you looking for these?
107034E2 Connect Quattro
10805802 Connect 4K

They work, I can still watch live TV with them, but I cannot record – and it all worked before I upgraded to macOS27 (and, as I said, also reverting to 26.7 on a test machine)

Yes, and Yes.

I noticed that there are DVR builds for WD-NASes, so I went ahead and set that up and it works. So I have a working DVR again, but not where I really wanted it.

An excellent idea!

I wasn't aware or had forgotten there were recording programs for linux, but that probably works better for me than my Mac mini. I've got an always on linux box with an AMD Ryzen 9 processor which is much faster than my M1 Mac mini. I downloaded the recorder app for that and it's running for me now on linux. Also, not where I'd planned for it but it may work out better for me in the long run. We'll see.

OK, after doing some digging into the problem today (I'd like to record a couple of the college football games) I <think> I found a solution that works for me.

I became superuser and changed into the/Library/LaunchDaemons/ directory, and did a directory listing there. Something that stood out to me was that the com.silicondust.dvr.plist file had an @ sign at the end of the permissions column, indicating it had an extended attribute. Checking the attributes with "xattr com.silicondust.dvr.plist" showed that the com.apple.quarantine attribute was set on that file. I cleared that attribute ( xattr -c com.apple.quarantine ) and rebooted. When I opened the HDHomeRun viewing app and checked the settings (gear) devices tab, my Mac once again shows up as a recorder...

Now to see if it actually records the games. I'll check back tomorrow with results, one way or another.
