Your Mac is drowning in AI-era junk. Take the gigabytes back.

The headline is what you can recover, not what is left. Free space is already in the menu bar all day — repeating it as the panel’s biggest number spends the largest type on something you just read on the way in.

Look below the header in all three: the same rows, the same ticks, the same Clean selected · 17.6 GB. The header is the whole difference — roughly 40pt of panel for Ledger, 90pt for Gauge, 150pt for Map. Gauge is the default, and Map needs at least three items to be worth drawing: below that it falls back to Gauge and says why, instead of silently ignoring your choice. Small targets fold into one “Everything else” tile rather than becoming unreadable slivers.

• Last usedCaches you have not touched
• BuiltDerivedData, Gradle — cleaning forces a rebuild
• DownloadedPackage caches, installers — will re-download
• EmptiedTrash, since you last emptied it
• CapturedScreenshots — you may still need these
• BootedSimulators you last ran months ago

Old is the safe thing here, so the usual heat map is inverted: cold and forgotten is green, freshly touched is amber. Anything older than your stale setting arrives pre-ticked, anything newer arrives untouched — and the footer says so: “1 item left unticked because it was touched recently.”

“Stale” is one number driving three things: when an age turns amber, what the review filter chip says, and what arrives pre-selected. Defaults are 20% orange, 10% red, 30 days stale — and the target list doubles as an explanation, greying out “Docker — not installed” so you know why the scan found four things instead of twelve.
