title: Trouble Starting MongoDB (Mac) - Code: 100
body: <p>I installed MongoDB via Homebrew and seem to be having some trouble starting when I run the mongod command. I have tried setting a up the data/db directory correctly and viewed a few other answers on stackoverflow, but haven't been able to figure this out. Here is what I keep getting (sorry I am new to this):</p>
