That “your disk is almost full” notification is one of the more frustrating things your Mac can throw at you, especially when you have no idea what’s taking up all the space. A good rule of thumb is to keep at least 10% of your drive free, but figuring out what’s eating into that can feel like a mystery.
Visual tools like GrandPerspective and DaisyDisk give you a colorful map of what’s on your drive, which is great if you want a bird’s-eye view.

It lists your folders sorted by size, so you can drill down level by level until you find the biggest culprits and trash them on the spot.
