Question posted in 
I recently completed the m001 basics course on Mongo University and connecting to Atlas with the connection string was not a problem. With experimenting I messed up and now I am not able to start mongo. The steps I followed are (from my root directory):
brew doctor --verbose
to make sure Homebrew is running correctly and there were no issues.
HomeBrew version: 3.0.1,
macOs: 11.1,
Homebrew Cask Staging Location: /usr/local/Caskroom
Homebrew Cask Taps: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask (3823 casks)
/usr/bin/xattr
-
brew cleanup -
brew update -
brew tap mongodb/brew
Mongo Docs installation -
brew install [email protected]

brew services start [email protected]
Service mongodb-community already started, use brew services restart mongodb-community to restart.
brew services restart mongodb-community
==> Successfully stopped mongodb-community (label: homebrew.mxcl.mongodb-community)
==> Successfully started mongodb-community (label: homebrew.mxcl.mongodb-community)
- kevinturney / $
brew services list
Here is the error:

I checked the processes,
ps -ef | grep mongo

ps -ef | grep mongod

mongo --version

When I run brew services start mongodb-community it successfully starts and then
mongo this is the result:
kevinturney / $ brew services start mongodb-community

kevinturney / $ mongo

I followed a very similar StackOverflow question, went though mongo docs, uninstalled, reinstalled, Also, tried this great post I am not sure what to try next.
