Extract MongoDB from the the downloaded archive, and change the name of the directory to something more palatable: cd / tar -zxvf mongodb-osx-x8664-3.0.7.tgz mv mongodb-osx-x8664-3.0.7 mongodb. Create the directory where Mongo will store data, create the “db” directory.ou can create the directory in the default location by running mkdir -p /data/db. Mac OS Catalina 10.15.4 I installed the MongoDB server Community edition on my Mac without a problem (seemingly). I then installed MongoDB Compass community edition, from the MongoDB download.
