Uninstall MongoDB (MACOS) completely

Remove all the mongoDB contains before reinstalling

1. Check to see if any mongo service is running

launchctl list | grep mongo

2. Unload from LaunchAgents

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
rm -f ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
launchctl remove homebrew.mxcl.mongodb

3. Kill all the processes related to mongod

pkill -f mongod

4. Uninstall the mongodb

# If installed via brew
brew uninstall mongodb  
# If installed manually you can simply delete the folder
rm -rf <mongodb_folder>

5. Re-confirming if mongo related file still exists

ls -al /usr/local/bin/mong*
ls -al ~/Library/LaunchAgents

6. If you have separate folder for db

rm -rf /usr/local/var/mongodb
rm -rf /data/db

That’s it! If there are still something I missed please comment below.
