I have channels on a Mac Mini (M1 chip) and Tahoe updated last night to 26.5.2 and now Channels won't load.
Check under macOS System Settings > Privacy & Security > Local Network and make sure that Channels DVR has access.
Or are you referring to the client app?
No...it isn't the client ...it is the server......It works now....what happened was the OS did an update last night and part of the update hung for unknown reasons (it said it was Xcode tools) --- and I called Apple support and I was almost ready to give up when they suggested unplugging it for a while. When I did that, the missing part of the update continued successfully.
It wasn't just Channels - it was everything. I have a visit to the genius bar to cancel.
Funny thing...I also have an M4 mini and it had no trouble with the Tahoe update.
OK...now I am stumpted....I got Channels proper working but my FASTCHANNELS have zero channels and if I go to FastChannels ADMIN....the site can't be found. Dockers is running....I must have a setting wrong somewhere.
UPDATE....I Had to press the "Play" button on the Docker APP for FastCHannels to run.....it must not automatically start.
