I just recently switched to Infuse 8 after buying a couple Apple TV boxes. The network sharing + iCloud timestamp syncing between my phone/macbook/multiple TVs is the best thing ever. My macbook is basically a media server for every device in my house. No need for annoying plex servers.
It's free software, it's keyboard friendly, it supports more of less every format, and it blends into the OS's native desktop environment. I don't have an eye for design, but it seems good to me. If there's a better choice for local multimedia playback on macOS, I don't know what that is.
(It seems the only other real contender on the backend is VLC, which is likewise excellent software.)
Does VLC already support HDR content on MacOS? I switched to IINA because of that omission.
Maybe some day when I have more external displays with OLED or something else that can do millions-to-one contrast ratios, I'll play around with HDR and see if I can find a way to reliably make it comfortable, but for now I don't own any-- it's just the built-in displays of my mobile devices, and I spend as much time as possible on much larger screens because I also have visual acuity problems.
