The record

Purpose: MKVToolNix is a set of tools to create, alter and inspect Matroska files.
Merge: mkvmerge joins selected or all streams from several media files into a Matroska file.
Inspect: mkvinfo prints information about elements in Matroska files.
Extract: mkvextract extracts tracks from Matroska files into other files.
Edit properties: mkvpropedit modifies properties of existing Matroska files without a complete remux.
GUI: MKVToolNix GUI provides an interface for mkvmerge and includes a chapter editor and a header editor.
Platforms: The maker provides downloads for Windows, Linux distributions and macOS; the current macOS downloads are DMGs for macOS 13 Ventura and newer.
Windows requirements: The current Windows releases support Windows 10 and Windows Server 2016 or newer and are offered as installers and portable 7zip archives.
Linux AppImage: The distribution-agnostic Linux AppImage should run on distributions with glibc 2.28 or later.
Integrations: MKVToolNix can be installed through package sources including Chocolatey, Flatpak, Homebrew and MacPorts.
Container option: A community-maintained Docker image for the GUI can run on systems such as Synology and Unraid NAS, and the maker says it does not provide support for that image.
Download authenticity: The maker signs source archives and package repositories with GPG keys and signs Windows binaries with a code-signing certificate; the site also provides checksums for Windows downloads.
Support: The maker asks users to report errors through bug reports and lists a forum and issue tracker as support channels for macOS builds.
Notable limitation: The Microsoft Store edition allows users to run only the GUI, while its functionality is otherwise identical to non-Store editions.
