I've been in a constant battle with disk space lately, so when Mole came across my radar I gave it a go.
It's a macOS command-line tool that bundles a bunch of system maintenance tasks into one binary — deep cleaning caches and logs, smart app uninstalling (including all the hidden launch agents and preference files that normally linger), build artifact cleanup (node_modules, target, venv etc.), and a live system monitoring dashboard.
I installed it, ran it, and got back over 20GB. Just like that. For something that took maybe five minutes it was genuinely satisfying. Highly recommend giving it a run if you're in the same boat.
