Itβs best to get rid of what mysql server has ever installed and install it through Brew

You can also just install mysql in addition to the one you are using, but this is not recommended.
brew install mysql
hope the brew version is new enough to support it.
Before resetting the old mysql installation, it might be nice to export using a tool like navicat.
