Mac users interested in Ps3muxer subtitles generally download:
PS3Muxer is a video file remuxing utility for the Mac. A remuxer is basically a video editing tool that can deconstruct a video file and then convert either the video or the audio, both, or none to make the file playable on a specific device. In this case, the target device is the Playstation 3. The PS3 can't play MKV files, but it can play M2TS files.
