You know you can run Docker's in MacOS as well right? I believe it will require Rosetta, but it can be done. If you wanted to give Jellyfin a try in a docker that is.

But if you don't want to go down that road, you could always try Emby:
Bittorrent cant be shut down, that much is obvious.
However. Its potential use is vastly underestimated by those researchers. As a sync tool, method of getting information from en to people or "leaking" documents it is extremely powerfull. This also makes it a perfect tool for illegal downloads, Time4Popcorn / Popcorntime etc etc.
Case: I'm working at a local retailer selling computers, ipads, display's etc etc. Yesterday a client walks in and asks how she can output her movies from a Macbook Air to her Tv. Sure, just use an AppleTV, very easy etc etc something apple ecosystem etc. However it turns out she want her Time4Popcorn stream to output to her nice plasma Tv. No Can Do.
After selling her a minidisplay to HDMI cable I asked some more about why she used a torrenting program and what she knew about it. Me: Why use time4popcorn and not use Netflix (etc) ? Since Time4popcorn is a bittorrent based system and governments constantly try to take them down. She: Dont know, they did have 2 days downtime due to maintanance Me: No that was a DDOS attack / they got shut down again. She: oh... i had no idea.
My point is, acces tot content should and COULD be far better, even including the use of bittorrent (sync). Netflix and Hulu (etc) are gaining a lot of ground. Why? Because its easy. Those researchers might want to include that little fact in their conclusion
Also, this (pretty funny) video explains a lot about the fear "they" have for piracy. Click here to view the TED talk. (The 8 Billion iPod by Rob Reid)
