Software Recommendation: IINA
If you're on MacOS and are looking for an attractive, free media player, you might consider IINA. I don't consider it a replacement for my venerable VLC, but it's an interesting and robust player that's found a spot on my Dock. I especially appreciate that it seems to be designed to feel like MacOS software in a way that (for example) VLC doesn't. It's fast, stable, open source . . . and did I mention free?
