How to clean up the Downloads folder on a Mac automatically

Short answer: macOS never empties Downloads by itself. What you can safely clear out: installers (.dmg, .pkg) for apps you’ve already installed, zips you’ve already unzipped, and one-off files you haven’t opened in weeks. Sort Downloads by Date Added to find them, or use an app that moves them out on a schedule.

Why Downloads fills up

Every browser, Mail and AirDrop drop files there, and nothing ever takes them out. The usual suspects:

Find what’s old

  1. Open Downloads in Finder and switch to List view (⌘2).
  2. Right-click a column header and turn on Date Added, then sort by it. Date Added is when the file landed in Downloads, which is what you want here.
  3. Sort by Size to see what takes the most space.

On recent macOS, System Settings › General › Storage has an ⓘ button next to Documents that lists your large files and downloads, sortable by size or by when you last opened them.

Clear out the safe stuff

Files in the Trash still take space until you empty it. Finder › Settings › Advanced › Remove items from the Trash after 30 days permanently deletes anything that has been in the Trash for 30 days.

What doesn’t help

Or let it happen by itself

Attic is a small menu bar app that does this on a schedule:

Files go to ~/Attic, sorted by month. Attic never deletes anything on its own; when you want the space back, you pick what goes to the Trash.
