MKVtools
MKVtools is a video conversion and container editing utility for macOS that specializes in working with Matroska (MKV) files. It lets users convert videos to MKV format or to MP4, edit metadata within containers, and apply presets for playback on devices like iPhones, iPads and Apple TVs. The app targets casual users and power users who work with MKV files without needing full video editing capabilities. It includes preset configurations for common output targets and can process multiple files in batch.

1 suggestionMKVtools has not been updated to a native Apple Silicon build. The latest available version (3.7.2) is Intel-only (x86 architecture), and the last documented update to the project was around 2015 according to the copyright notice embedded in the binary. The app continues to run under Rosetta 2 today, but Apple is removing Rosetta support in macOS 28 (September 2028), at which point this Intel-only build will no longer launch. Since the developer appears inactive and no native version has been released, you should begin exploring alternatives now. For straightforward MKV-to-MP4 conversions, FFmpeg (free, open-source, and natively available via Homebrew) covers the core task with a command-line interface. For a graphical tool with broader video conversion capabilities and confirmed Apple Silicon support, consider Handbrake, which handles MKV input and is actively maintained with native builds. If you require metadata editing within containers, VidCoder or MediaInfo paired with FFmpeg provide similar workflows on Apple Silicon.
