In this video I show you how I clean and optimize my Mac for free using MOLE, a simple open-source Terminal app. If you’re tired of random “cleaner” apps that feel sketchy, MOLE is the opposite: transparent, lightweight, and it does the job with a clean menu right in your Terminal. I walk you through what MOLE is, what it can do, and why I like using a tool like this instead of paying for yet another utility. I start with the setup: installing Homebrew, installing MOLE from the developer’s tap, and then launching it with a single command. After that, I go step-by-step through the main things you actually care about—cleaning macOS system cache, uninstalling apps properly, running basic optimization tasks, exploring disk usage to find what’s eating your storage, and checking system health. The takeaway is simple: you can keep your Mac snappy and organized without spending money, as long as you use a tool you trust and you understand what you’re cleaning.
