On a mac here too and I've tried a bunch. There's Serviio if you really don't like PLEX. But, in my experience PLEX has been the easiest, even though it has a ton of features you don't use. It's reliable and not buggy. These days if for DL's I'm just using Plex with DLNA enabled, streaming through the SLR app. I've tried a number of VR player apps, too. SLR/DEO is my fav now because it's so easy to reposition video on the fly. I used to use MobileVRStation, but haven't touched it since getting a subscription to SLR and using their app.
