Problemas de instalación de mariadb en MacOS Catalina Homebrew

Edición 2020-10-12:

Estoy en MacOS 10.15.7, las versiones en fórmulas de cerveza es 10.5.6 para mariadb y 8.0.21 para mysql. (puede consultarlas en /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/{mariadb,mysql}.rb ).

Mysql funciona bien después de una instalación limpia por brew uninstall mysql y eliminar todo lo relacionado en $(brew --prefix) , pero mariadb sigue sin funcionar con brew unlink mysql && brew link mariadb && brew services start mariadb sin eliminar los archivos de la base de datos mysql en $(brew --prefix) .

Pregunta original:

Así que estoy corriendo MacOS 10.15.2 Catalina y tratar de instalar mariadb (10.4.11, la última versión) con Homebrew.

Después de correr brew install mariadb , brew advirtió que el postinstalllation no se ha completado con éxito:

Try 'mysqld --help' if you have problems with paths.  Using
--general-log gives you a log in /usr/local/var/mysql that may be helpful.

You can try again using `brew postinstall mariadb`

Soy nuevo en mariadb / mysql y por eso he seguido esta guía de mariadb.com (como señaló @klanomath, esto es obsoleto (2016)) y corrió mysql_install_db :

$ mysql_install_db
WARNING: The host 'mymac' could not be looked up with /usr/local/Cellar/mariadb/10.4.11/bin/resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MariaDB version. The MariaDB daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MariaDB privileges !

He investigado un poco pero no he encontrado nada útil. ¿Cómo puedo completar mariadb ¿Instalación? Se agradece cualquier ayuda.
