At work we are issued a very fast Apple MacBook Pro (mine is an M4 with 64GB RAM) and we take that fast machine and install Microsoft Defender on it, which takes that fast computer and makes it wade through a swamp. This post isn’t about the pain that I go through daily to try to develop directly on my Mac (that should be a separate series of posts) but today I want to talk about how I have greatly improved my nix-darwin switch speeds.
