Homebrew, Gradle, and the Hidden Caches Eating Your Mac's Storage

Most developers know about the big offenders — Xcode's DerivedData, Docker images, node_modules . But there's a second tier of caches that almost nobody thinks about: Homebrew downloads, Gradle wrapper distributions, Maven repositories, Go module caches, Ruby gems, and IDE workspace storage. None of these is massive on its own. Homebrew might be 3GB. Gradle caches, 8GB. Your IDE's workspace storage, another 4GB. But stack five or six of these together and you're looking at 20-40GB of disk space
