With regards to Mongodb and Homebrew it's giving you and error because you have previously installed an older version of the formula. As per the Mongodb docs :
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/
To fix the ChecksumMismatchError Remove the downloaded .tgz archive.
brew untap mongodb/brew && brew tap mongodb/brewRetap the formula with the updated version.
