1. VLC is a free and open source cross-platform multimedia player that provides users with a simple interface and customization options to play MKV files in a Mac, and almost anything ranging from video files, audio files, CDs, DVDs, ISO, network streams and more. To play (HD) MKV in Mac, just download and installed the program on your Mac.
2. Another way to play MKV files on Mac and PC is to convert them to MP4 or MOV. However, it is not simple to convert MKV files since it contains multiple codecs. From this point, we recommend AnyMP4 Video Converter Ultimate. It lets you to edit and adjust your MKV files before converting.
3. Download Media Codecs to Play MKV (PC & Mac) A codec is a computer program used to encode or decode any kind of digital media files. In our case, we need codecs that will let you play MKV videos with a default system player. There are a lot of free codecs online that you can use for this scope. All have their pros and cons.

What app plays MKV files on Mac There is nothing native on macOS to open or play MKVs. To play MKV files on your Mac, you need third-party help. VLC Media player from VideoLAN, Plex or 5KPlayer can.

If you’ve never heard of the MKV file format, you’re not alone. It’s a newer standard than familiar file types like MOV or the more standard MP4 format. But there’s good reason it’s been popping up, and now is a great time to learn about converting MKV to MP4.

MKV is gaining traction because it can support an endless number of videos, audio files, pictures, or subtitled tracks in one file. It’s also open-standard, and free. The term MKV is acronymous for “Matroska,” commonly known as Russian nesting dolls. (See, all kinds of files nesting into one larger file!)

Let Setapp deal with file formats

Convert MKV to MP4 or get a media player with native support for MKV. Setapp is a one-stop toolkit that solves any problem on Mac.

This ability to wrap all types of media into one file type is what makes MKV so popular. But it’s only available to a limited number of devices, and most often used as a video file-type rather than for true multimedia files. Because it’s open-standard, there’s no advantage for large tech firms like Apple to support MKV, or adopt it onto their platforms.

In fact, there’s no native support for MKV within macOS. If you were sent an MKV file, you would quickly have to convert the MKV to MP4. In this article, we’ll talk you through how the conversion works using several different MKV to MP4 converter apps.

MKV to MP4 without losing quality

Remember when we said MKV files were still not terribly popular? Don’t worry, we haven’t forgotten about that. There will still be plenty of times you’ll need an MKV converter for your Mac, especially if you’re going to share your files with anyone. Chances are they will find the MP4 format much easier.

For this use-case, we recommend Permute converter. It’s an app focused on converting just about any and all file types to – well, just about anything! It’s really simple to use, too. Here’s how to convert MKV to MP4 using Permute:

1. Open Permute.
2. From the menu bar, go to File > Open.
3. Select the MKV file on your Mac you’d like to convert.
4. Select ‘Open.’
5. From the ‘Video’ dropdown menu, select ‘MP4.’
6. Click the ‘play’ button in the sub-window housing your MKV file. Keep in mind the video itself has a play button, too; the play button on the sub-window is what starts the conversion.

That's it! Your MKV file will convert to the MP4 format. Keep a few things in mind before you start a transfer, though. In the upper-right corner of the sub-window, you’ll see a gear icon. This is where you can control where your converted file is placed. You can also make other changes like rotating the video, should you need that functionality.

Permute is also adept at batch conversion of files. If you had a few MKV videos you wanted to convert to the MP4 format, you don’t need to go one-by-one. You could choose multiple videos in step three above, if they were all in the same location on your Mac. If the videos were in different places (one may be in downloads, the other in ‘documents,’ another in a folder – you get it) you could simply repeat steps two, three, and four until all your videos were added.

The ‘sub-window’ in Permute holds files to be converted, so adding multiple videos will convert them all the same way. Keep that in mind before you start; if you didn’t want all your videos to be MP4s, you’d have to create new groups.

That’s pretty simple, though. On the bottom left of the video is a gear icon, where you’ll see an option to ‘create new group.’ Simply do that and you’ll find the video in its own sub-window, ready for conversion to a different format.

How to play MKV on Mac

Because MKV isn’t natively supported, you shouldn’t expect your Mac to spin up QuickTime to play downloaded files as it does with so many other media file types. Instead, we have two great options for MKV playback: Elmedia Player, and Movist Pro.

Elmedia Player is exceptionally strong at playing just about any file type you can throw at it. The app uses hardware accelerated decoding to play files, which ensures your MKV playback will be strong. Elmedia player also supports MP3, MP4, SWF, FLV, AVI, MOV, and DAT file types.

Here’s how you can play any MKV file using Elmedia Player:

1. Open Elmedia Player.
2. From the menu bar, go to File > Open.
3. Select the MKV file on your Mac you’d like to play.
4. Select 'Open.'
   

And that’s it! Your MKV file will automatically play in Elmedia Player. In the Elmedia Player window, you’ll be able to pause and play your file, fast forward or rewind, and choose the volume level. On the bottom right of the screen you’ll see a gear icon, where you’re able to finesse the playback speed, manage audio and subtitle delays, control the brightness, saturation, contrast, gamma, and hue of your video, and enjoy a full equalizer for your MKV video files.

Movist Pro is just as impressive when it comes to video playback. Here’s how to play an MKV video on Movist Pro:

1. Open Movist Pro.
2. From the menu bar, select File > Open File.[MKV3]
3. Select the MKV file on your Mac that you’d like to play.
4. Select ‘Open.’

Deja vu, eh?! It’s the same process as Elmedia Player, which is great. Movist Pro has a lot of really great things going for it, too.

It has a really minimalist interface, with controls that quickly dive out of the way when a video is being played. The scroll-bar is as far to the bottom as possible, and the ‘play’ button is all the way on the bottom left. Even with controls on-screen, you end up seeing more of the video than with most other players.

Movist also supports the Mac’s native picture-in-picture mode, which pins a video to the bottom-right side of your screen. It’s a great way to keep track of videos while doing other things.

If you’re just looking to play a particular section of a file, Movist Pro has a really neat feature that lets you choose a range within a file, and loop the playback for that range. You can also add bookmarks to any video; an excellent option if you want to keep tabs on a video lecture, or mark favorite parts of a movie.

When you need to convert MKV to MP4, there’s nothing better than a simple, effective converter. For our liking, Permute is the way to go. It’s simple, effective, and doesn’t create any issues with the converted files. Too often we’ve seen converters which degrade the quality of a video.

Playback is also a critical component. While Permute can convert with ease, you may not always need that feature. Besides, you’ll want to watch your converted video files, too!

Watching movies on a laptop is not the best way to do it but you can’t carry a TV on the Plane, yet. While the Quicktime Player handles all of my media content with ease, there are certain formats that it still can’t recognize. The MKV format is one of the popular ones in the movie industry because of it’s unlimited storage capacity. In this guide, I’ll show you how to play MKV files on a mac. Let’s get started.

The MKV format is an open and free container format that can hold an infinite number of audio, video, and text files in a single file. This makes it an excellent format for TV shows, movies, etc.

There are various options to play MKV files on Mac but we’ll choose the easiest three;

• Installing a QuickTime Plugin
• Installing a third party Player
• Converting the Video

1. Play MKV Files on Mac – QuickTime Plugin

Quicktime Player is the default video player for macOS. Yes, it does lack a few features which other players have but it’s nothing a plugin won’t fix. Perian is a popular Plugin for QuickTime Player which lets you play MKV videos on your Mac.

Download the Plugin setup file from the official website or by clicking this link.

Mkv Player Mac Download

Your download should automatically start and once the file is downloaded, you can simply open the downloads by clicking the downloaded button on the tray. Click on ‘Perian.dmg’ to begin the setup.

It would show the error just like the figure below, which says “Perian can’t be opened because it is from an unidentified developer”. Fret not, you can easily remove this error, by temporarily disabling the security blanket of GateKeeper.

To disable Gatekeeper, open ‘System Preferences’ by searching in the Spotlight or from the Apple  menu. It would open the settings window and you can click on ‘Security & Privacy’.

After that, you’d see the section which says ‘Allow apps downloaded from’ and a button ‘Open Anyway’. Click the button to override the default action.

If your Mac has a password, you need to enter it again to authenticate it. Make sure you enter the Administrator’s name and password or else it won’t install the plugin.

Now, this will open the installer and you just have to click ‘Perian.prefPane’ to begin the installation.

Ignore this warning and allow it by clicking ‘Okay‘. It automatically installs all the necessary files and you just have to wait for it to finish.

After the installation is finished, you’ll see the window similar to one below. You can close it now as the Plugin is successfully installed.

Play the MKV file with Plugin

Now, you can open any file from your system with QuickTime Player and it would start loading instead of showing you an error. Depending on the Size of the file, it may take some time.

This Plugin converts the MKV file to MP4 and that’s why it takes a little while to load. Once it does, you can watch the video without any problems on your QuickTime Player. If you close the window, you’ll get a pop-up that would suggest you save the file in MP4 format. You can save the file in MP4 format and play that instead.

Pros

• No additional Player required
• Easy installation and integration
• Open-sourced
• Converts MKV to mp4 as well

Cons

• Slow loading speeds

2. Play MKV Files on Mac with VLC

The last method works great if you want to keep using QuickTime Player as your main media player on the computer. The Plugin is still a workaround and slow when compared with other media players.

The VLC media player is one of the most popular video players out there and the popularity keeps growing because of its consistent and reliable performance and support for a wide range of formats and codecs. You can install VLC to play MKV files and other formats without installing any special plugin. You can even set it as a default media player on mac.

Go to the VLC’s website and download the latest package or click this link.

It opens the download page and beings the download in a few seconds.

Once the download is finished. Double click the package in the Downloads to install it.

As it unwraps the container, you’ll see the window like the one below, you have to drag the traffic cone to the applications folder by clicking and holding the icon.

It would prompt you with an authentication pop-up, Click ‘Authenticate’ button to begin the installation.

It may ask you the login credentials. Enter the administrator username and password and click ‘Modify Settings‘.

VLC media player would install and now you can play any MKV file with VLC media player. Simply right-click the MKV file and select ‘Open With’. Click on the VLC icon. It begins to play the video without a hiccup.

Pros

• Support for a wide variety of Plugins
• Native support for MKV
• Sleek UI

Cons

• Problems with 4K playback

3. Play MKV Files on Mac With Handbrake

If for any reason, you can’t use the above two methods. Converting the MKV files to a supported format is the best option. Using a web converter is both time-consuming and slow, considering you have to first upload, convert, and then download the converted file again.

Handbrake is an open-sourced video transcoder that is used to rip DVDs and it also lets you convert MKV files to mp4. Installing Handbrake on your mac would take no more than five minutes. Go to the website or click this link to download the installer package.

Start by clicking the downloaded package in the Downloads folder.

Mkv Player For Windows 10

It would open the container and you can click on the Handbrake icon to launch the converter.

To select an MKV file for conversion, click the ‘Open Source’ button on the top left corner of the window.

Select the file from the computer by browsing to the desired folder.

After selecting the file(s), you can select presets, and adjust video duration. You can edit dimensions, filters, video, audio of the output file. After you’re done with the tweaks, choose the output folder, and click start.

After the conversion, The output file is automatically stored to the destination address. You can open the folder and play the file on any media player or send to other devices using iTunes.

Pros

• Multiple files can be converted at once
• Multiple presets are available
• Full control over dimensions, audio, chapters, etc

Cons

• Only converts to MP4
