In this tutorial I am going to talk about how you can install MongoDB on MacOS in an easy way. I have gone through many tutorials online, but I have been really upset with those tutorials. Most of the tutorials are outdated and old. So I decided to create this tutorial in which i can show you a better and easy way to setup MongoDB on MacOS.
MongoDB expects the Data/data/db folders to be in a location which Mac OS Catalina does not allow. As a consequence the folders must be placed elsewhere, on one of the disk volumes. But modifying the MongoDB settings to find the new data folders is not working properly. There are many supposed solutions for this in various places on the web but none of them have solved my issues. These are the most probable errors and how to solve and setup MongoDB on macOS Catalina. Please do have a look into my YouTube channel: Code Studio Sai Ankit that discusses everything related to coding from Computer Science Concepts, Competitive Coding tutorials, Codeforces Editorials, Development Projects.
