MacMonitor is a native Mac app that shows what's filling your disk and cleans it safely. Clean System Data sorts it into safe to clean, worth a look, and managed by macOS. Smart Scan finds junk, build caches, AI models and idle apps in one pass. Organizer sorts messy folders, and Activity shows CPU, memory, disk and battery. You review everything first, cleanup goes to the Trash with Put Back, and nothing is uploaded. One-time purchase, macOS 14+. Try it in your browser: macmonitor.app/demo
