Ways to Play MKV Files on Mac

Can’t find ways to play MKV files on Mac?

The Matroska or the MKV is a multimedia container format that contains codecs of HD quality videos, audios, pictures, subtitles, and more. It’s a universal format through which you can watch 720 or 1080 pixels video files with audio tracks and subtitles available in multiple languages.

Windows PC comes with a built-in codec that can play the files with the .mkv extension without any trouble. But QuickTime, the default media player of Apple devices, does not support such file types. Hence, every time you try to play the MKV file in QuickTime, you’ll get an error message stating “Invalid file.”

Now, you can always use a different player, but that may result in the video being played with constant interruptions and errors or not being played altogether. To help you discover ways to play MKV files on Mac, here are some of the best methods you can adopt.

So without any delay, let’s get straight to it!

1. Use QuickTime Plugins.

If you want to stick to the default media player of Apple and play the MKV file, you can install a plugin on your system. It works by enabling the player to support various file types not included in the original version of the program.

However, be wary of the plugins that include bundle links to other third-party applications and websites. That said, the safest and most widely used one is the Perian plugin. It is a free and open-source plugin with an easy installation process.

To use the QuickTime plugin, here’s what you need to do:

  1. To get started, download Perian from its official website.
  2. Now to set up the plugin, open File Explorer and go to Downloads
Downloads folder Mac
  1. Find the Periam.dmg file and click on it. You will receive a message saying, “File can’t be opened because it is from an unidentified developer. Click on OK.

Although this is one of the easiest ways to play MKV files on Mac, it is not the fastest. The player may take longer depending on the file size.

2. Use VLC Media Player.

The above-explained method works well if you want to continue using QuickTime as your default media player on Mac. However, if you’re willing to switch to another player, VLC should be your first option.

It is universally considered to be the most reliable media player due to its excellent performance and the vast range of supported formats and codecs. This program works without needing to install plugins separately. What’s even better is that you can make it your Mac’s default media player.

Follow the steps below to download and set up VLC Media Player on your Mac:

  1. Firstly, go to the VLC official website to download the latest available version of the software for Mac.
  2. Once the file is downloaded, go to the File Explorer and click on Downloads.
  3. Then, double-click on the most recent downloaded file.
  4. In the next window, click and hold the Cone icon and drag it to the Applications folder.
