Stop Dock Icons Bouncing
An icon in your Dock is bouncing like it had too much coffee, and it will not stop until you look at it. That bounce is macOS waving for attention — a finished download, a message, an app that needs a decision. The bounce is the messenger; find the message.

TL;DR / Quick Fix
Quick fix: Dock icons bounce to demand attention — usually a finished download or an app needing input. Click the bouncing icon to see what it wants; the bounce stops once you acknowledge it. To reduce bounces, check the app's notification settings. There is no global bounce off-switch.
Follow these steps
- Click the bouncing icon. Bring the app forward. The bounce almost always stops the moment you see whatever it wanted to show you.
- Read what it wants. Common causes: a completed download, an incoming call, a dialog waiting for a yes/no, or an error the app cannot show otherwise.
- Check the app's notification settings. Apps that bounce constantly usually have alert-style notifications enabled. System Settings > Notifications > the app lets you calm them to banners or silence.
- Distinguish bounce from badges. A red badge counts unread items quietly; bouncing demands immediate attention. Fix the underlying alert and both calm down.
- Quit the app if it is stuck bouncing. Rarely, an app bounces over a dialog it cannot display. Quitting and relaunching clears the stuck state.
- Accept the design. Bouncing is macOS saying this needs you now. There is no master switch because silencing it would hide genuinely urgent alerts.

What NOT to do
- Do not force-quit every bouncing app in anger. The bounce is information — read it before killing the messenger.
- Do not confuse bouncing with a virus. No malware announces itself by bouncing politely in the Dock.
- Do not disable all notifications to stop one app. Tune the noisy app individually; the others are behaving.
- Do not expect Terminal to fix this. Bouncing is app behavior, not a Dock preference — no defaults command governs it.
Frequently asked questions
Why does the icon keep bouncing after I clicked it?
The app still wants something — a hidden dialog, a permission prompt behind other windows. Look for a window demanding input.
Can I turn off bouncing completely?
No global switch exists. Per-app notification settings are the only lever, and some system alerts always bounce.
Does bouncing drain the battery?
Negligibly. The animation is brief and the Dock is already running — worry about the app's actual work, not its dance.
