Apple - Is there a MariaDB server package for Macos?

You can download the latest (November 2018) release with an official macOS build here:

http://archive.mariadb.org/mariadb-10.1.37/macOS/

They do not provide macOS pkg builds for later versions such as 10.2, 10.3 or (alpha) 10.4.

Grr... I found out my problem. I had gone to MariaDB.com instead or MariaDB.org.

Downloading from https://downloads.mariadb.org/ has all the packages I was expecting except for the .tar.gz version for MacOS. I guess they only provide a .pkg file.
