IN ONE LINE
Your Mac keeps a record of where you've been. TrailSift finds it and clears it.

SHORT
TrailSift for Mac finds the record of where you've been that other cleaners miss: download logs, remembered networks, addresses, photo locations. Free audit.

LONG
Your Mac keeps a quiet record of where you've been. macOS logs every file you download, with the address it came from, and leaves that address on the file itself. It remembers every Wi-Fi network you've joined, everyone you've emailed or messaged, and the words you've typed. Browsers keep lists of secure sites that survive clearing history, photos record where they were taken, and deleted apps leave their folders and startup items behind. Private browsing stops none of it.

TrailSift checks more than 30 of these places, reading only, and shows what's in each: how many, how big, from when, and what it is. Then it clears what you choose, after showing you exactly what will go. Files go to the Trash, databases are backed up for a week, and an app's data is only touched while that app is quit.

Free: the full audit, what changed since last time, leftovers of deleted apps by name, Privacy Settings, Photo Locations and the Hand Over This Mac checklist.

Pro, £15, $19 or €17 once: clear everything with a preview and the space freed before and after, the Clean Up Wizard, forget a site or the last hour everywhere, remove an app with everything it keeps, forget remembered addresses one by one, copies of photos without their location, scheduled clean-ups, and Word Search.
