Tuhi, your storage assistant · What Tuhi knows
Can Tuhi tell me whether my Mac actually needs a clean-up?
Short answer: Yes. Tuhi checks your real free space: with plenty of headroom it says there's no pressure, when space is tight it suggests Run Tuhi, and when it's critically low it points to the emergency screen. It matches the menu-bar health dot.
Yes. Ask "do I need to clean my Mac?" and Tuhi looks at your real free space and tells you honestly. When there's plenty of headroom it says there's no pressure — a tidy-up is a good habit, not an emergency. When space is getting tight, it suggests tapping Run Tuhi, and when the disk is critically low it points you to the screen built for that moment.
It uses the same thresholds as the colored health dot in the menu bar, so the answer always matches what the app shows.
