How do you uninstall MySQL from Mac OS X?
MysqlMacosOsx Snow-LeopardMysql Problem Overview
I accidentally installed the PowerPC version of MySQL on my Intel Mac in Snow Leopard, and it installed without a problem but of course doesn't run properly. I just didn't pay enough attention. Now when I try to install the correct x86 version it says that it can't install because a newer version is already installed. A Google query led me to perform these actions/delete these files to uninstall it:
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
And finally removed the line MYSQLCOM=-YES- from /etc/hostconfig
They haven't seemed to help at all. I am still receiving the same message about there being a newer version. I tried installing an even newer version (the current Beta) and it also gave me the same message about a newer version already being installed. I can't uninstall it from the Prefs Pane because I never installed the PrefPane also.

Aside from the long list of remove commands in your question, which seems quite comprehensive in my recent experience of exactly this issue, I found mysql.sock running in /private/var and removed that. I used
find / -name mysql -print 2> /dev/null
...to find anything that looked like a mysql directory or file and removed most of what came up (aside from Perl/Python access modules). You may also need to check that the daemon is not still running using Activity Monitor (or at the command line using ps -A). I found that mysqld was still running even after deleting the files.

OS version: 10.14.6 MYSQL version: 8.0.14
Goto System preferences -> MYSQL
Stop MySQL server
One option will be shown here to uninstall MYSQL 8 after stopping Mysql server

I also had a config file at /etc/my.cnf that I needed to delete on my Mac OS X Snow Leopard install

It might be overkill but your MySQL command history can also be wiped from:
~/.mysql_history

You need to identify where MySQL was installed to before attempting to delete it.
I always use the Hivelogic guide to installing under Mac OS X which builds MySQL from source. When setting up the build you can specify a directory under which to install MySQL with the --prefix parameter. You should make sure the directory does not exist and attempt to install from source.
./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \
--enable-thread-safe-client --enable-local-infile --enable-shared \
--with-plugins=innobase

You should also check /var/db/receipts and remove all entries that contain com.mysql.*
Using sudo rm -rf /var/db/receipts/com.mysql.* didn't work for me. I had to go into var/db/receipts and delete each one seperately.

This did the job for me:
brew uninstall mysql

For me, I had installed MariaDB years ago using homebrew. Correct uninstall procedure was: brew uninstall mariadb.
Solution 13 - Mysql
I also found
/Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
after using all of the other answers here to uninstall MySQL Community Server 8.0.15 from OS X 10.10.
