I have a MacBook Pro running MacOS Big Sur and I recently bought an external Blu-ray player so I could watch my Blu-ray collection while traveling. I'd read that VLC supported Blu-ray playback, but soon realised this was not the case. I downloaded the latest version of VLC and followed all the instructions at https://vlc-bluray.whoknowsmy.name/
It still doesn't work. VLC recognizes my blu-ray, but doesn't play. I'm not sure what else to try.
Any advice would be greatly appreciated!
