<p>Current MariaDB Server GA versions are formally not supported on macOS 10.x and 11.y. But it;s relatively easy to set up the environment and build it from current 10.2 - 10.7 GitHub sources, with few minor issues to resolve in the process depending on maxOS and major server version used. This talk is a summary of my related experience, with a quick review of related fixed and open bugs, as well as some unique features like DTrace support that one may benefit from on macOS.</p>
