Installing MongoDB on Mac (Catalina and non-Catalina) 14th Feb 2020. I had to reconfigure my Macbook after sending it for repairs. During the reconfiguration period, I noticed the instructions I linked to in “Setting up a local MongoDB connection” were outdated. Here’s an updated version on how to install MongoDB on a Mac. There are a few.

1. Homebrew (“Brew”) per se did not have issues after the Catalina upgrade. However, some packages delivered through formulae and casks have not been updated for Catalina and are stuck back in Mojave (or High Sierra, eek!). Old packages will likely have issues with Catalina since a lot has changed. For example, Catalina now uses Ruby 2.6.
2. Gd: 2.3.2: Graphics library to dynamically manipulate images: gts: 0.7.6: GNU triangulated surface library: libpng: 1.6.37: Library for manipulating PNG images.
