How Do You Uninstall Mysql from Mac Os X?

I also had entries in:

/Library/Receipts/InstallHistory.plist

that i had to delete.

If you installed mysql through brew then we can use command to uninstall mysql.

$ brew uninstall mysql

Uninstalling /usr/local/Cellar/mysql/5.6.19...

This worked for me.

ps -ax | grep mysql

*stop and kill any MySQL processes

brew remove mysql
brew cleanup

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySql*

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

edit /etc/hostconfig and remove the line MYSQLCOM=-YES-

rm -rf ~/Library/PreferencePanes/My*    
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*

*restart your computer just to ensure any MySQL processes are killed try to run mysql, it shouldn't work

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

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.

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.

Remove MySQL completely

Open the Terminal

Use mysqldump to backup your databases

Check for MySQL processes with:

ps -ax | grep mysql

Stop and kill any MySQL processes

Analyze MySQL on HomeBrew:

brew remove mysql
brew cleanup

Remove files:

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*

Unload previous MySQL Auto-Login:

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

Remove previous MySQL Configuration:

subl /etc/hostconfig` 
# Remove the line MYSQLCOM=-YES-

Remove previous MySQL Preferences:

rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*

Restart your computer just to ensure any MySQL processes are killed

Try to run mysql, it shouldn't work
