While I'd agree that the 10.11.x releases have terrible performance on some APIs to the extent that I rolled back to 10.10.x and marked it as held, until they release 12.x...

Jellyfin is a daily driver for me and works amazingly. I have thousands of films, TV shows, books, music, and it lets me navigate and use them perfectly well.

I have a wonderful little Linux media server.

What sort of bugs affect you?
