You are planning to watch your favorite movies, but the first video is not working on the media player. Even with other videos stored in your folder or videos online, they are not playing on Mac. Check out the following methods to fix the problem.

Unlike Windows and Linux, Apple only supports its own created video and audio formats. Even for MP4, which is a universally supported video file extension, your Mac can open it if it has codecs like MPEG-4, H.264, and AAC. Check for the file extension, and if it’s not supported, try to convert it using online or desktop converters. Otherwise, check the next solution.
