Stop MongoDB process:
sudo service mongod stop
Completely remove the installed MongoDB packages:

If you had installed MongoDB using Homebrew, unload mongodb:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist rm -f ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist launchctl remove homebrew.mxcl.mongodb-community
Kill the mongod process, if it exists:
pkill -f mongod
If you had installed MongoDB using brew, uninstall MongoDB with the below command:
brew uninstall mongodb-community brew uninstall mongodb-database-tools brew uninstall mongosh brew untap mongodb/brew

rm -rf /usr/local/var/mongodb
To check if the uninstall was properly done, check if any MongoDB files are still present:
ls -al /usr/local/bin/mongo* zsh: no matches found: /usr/local/bin/mongo*
