Minimize Mac windows to the app icon

Updated August 2026 · 3 min read

By default, minimizing a window drops a small live thumbnail onto the right side of the Dock, separate from the app it belongs to. If you'd rather minimized windows tuck into their own app icon, macOS has a setting for exactly that — Minimize windows into application icon — and you can flip it in System Settings or with one Terminal command.

Turn it on in System Settings

  1. Open System Settings → Desktop & Dock.
  2. Find Minimize windows into application icon in the Dock section.
  3. Switch it on.

That's it — no restart needed. From now on, when you minimize a window (yellow button, Cmd+M, or double-clicking the title bar), it collapses into the app's icon rather than parking a thumbnail on the Dock. The path is the same on macOS 13 Ventura, 14 Sonoma, and 15 Sequoia.

Or set it from Terminal

If you prefer the command line, or want to script your setup, use:

# Minimize windows into their app icon
defaults write com.apple.dock minimize-to-application -bool true
killall Dock

The killall Dock line reloads the Dock so the change applies at once. To go back to separate Dock thumbnails:

# Back to separate Dock thumbnails
defaults write com.apple.dock minimize-to-application -bool false
killall Dock

This is the same setting the System Settings switch flips — use whichever you like.

Getting a minimized window back

The one thing that changes is how you reopen a minimized window, because there's no thumbnail to click anymore. Two reliable ways:

If an app has only minimized windows and nothing else open, clicking its Dock icon simply restores it. Once the retrieval habit clicks, most people never look back.

Do it in one click

Mainspring surfaces minimize-to-application as a labelled toggle you flip on or off in a click — no Terminal, fully reversible. It's one of 90+ hidden macOS settings the app gathers in one place.

Change how the minimize looks, too

While you're here, you can also change the animation minimizing uses. The default genie effect can be swapped for the plainer Scale — see how to change the Dock minimize effect on Mac to pick the one you prefer.
