TrailSiftWhat private browsing doesn't hide
A private window keeps the browser from saving history. Your Mac and the network keep their own records.
Your Mac's hidden download log
macOS records downloads in a log of its own. Clearing browser history leaves it in place.
Before you sell or give away your Mac
The steps, in order, so nothing of yours goes with it.
Photos that say where they were taken
Share photos without giving away home, school or work.
What deleted apps leave behind
Dragging an app to the Trash leaves its folders, caches and startup items.
Every Wi-Fi network your Mac has joined
Hotels, offices, cafés and friends' homes, kept by name with the date each was last joined.
The addresses Mail remembers
Everyone you've emailed or messaged, suggested as you type, even after you delete the contact.
Old iPhone backups filling your Mac
Whole copies of phones you no longer have, with their messages and photos, often the largest forgotten files.
