VLC Media Player

Although pretty long in the tooth by now, VLC Media Player is still very popular with users, thanks in no small part to it’s free, open-source design and impressive list of customization options. Additionally, it supports playback of a huge number of popular and not-so-popular audio and video formats.

Where VLC shows its age is in the lack of ongoing updates to the base product compared to premium media players, which is why you won’t find handy features available like AirPlay and DLNA streaming. The interface can also feel a bit outdated when compared to sleeker, more modern alternatives, and performance on macOS can occasionally be vulnerable to stability issues.

Play MKV Files on Mac by Converting to Another Format

Another method for playing MKV video files on Mac involves using an app to convert the MKV file into a file format that’s compatible with Apple’s video player.

HandBrake

HandBrake is an open-source video transcoder app enabling users to convert files such as MKV to those more compatible with Mac devices, and the good news is it’s totally free. As well as MKV files, HandBrake can convert files from many other input formats, and even BluRays and DVDs. There are lots of options available for users who want to tweak specific settings for video output, such as filters, subtitles, and chapter breaks, which will be useful if users want to make any changes to the content or play order in their original MKV files. 

However, if you’re planning on watching lots of MKV movies, the conversion method isn’t the most efficient, as it will take up considerable time and hard drive space since you have to create an extra copy for every MKV file you want to view.

Movavi Video Converter

Movavi Video Converter is another great option that can convert MKV files into formats compatible with your Apple devices. It also has lots of extra features which make it very easy to use, and let you customize the output format before conversion to get the best result. In addition, Movavi lets users crop, trim and rotate videos, as well as apply various effects such as color correction and split-screen effects.

The downside of this video converter for Mac is that you have to pay quite a bit for access to its full feature set, although there is a free trial available if you want to test out what it offers first. All in all, Movavi provides an effective way of converting MKV files, so they are compatible with Macs, and it’s worth considering if you’re willing to pay for the extra features.

What is an MKV Format?

Short for Matroska Video, an MKV file is a multimedia container file that can hold a wide variety of different media data streams such as audio, video, subtitle, and chapter information, in a single file. Unlike other container formats like AVI, an MKV file can be of unlimited size, and their lack of compression allows for higher video quality. All these features have made MKV the go-to file format for many users for encoding and distributing digital video, and the MKV format is definitely one that Mac owners will want to be able to take advantage of.

Let’s explore the key advantages and disadvantages of the MKV format:

Pros

  • MKV serves as a versatile container format, capable of containing video, audio, subtitles, and metadata.
  • MKV format delivers high video and audio quality
  • It supports a menu structure
