Squeegee: A MacOS app to close old windows

Set rules like: auto-close Finder windows idle for 4+ hours

Clean you Windows: Squeegee is a native macOS app that closes stale windows. Set per-app rules ("close Finder windows 6 hours after I last used them"), and Squeegee closes each window when its time is up. It works per window, not per app: closing a stale Finder window leaves your active Finder windows open.

Features

• Per-window close timers -- Set a duration per app. Squeegee closes each window individually when its timer expires.
• Last active or opened -- "Last active" (default) tracks the last time you used a window. "Opened" counts from when the window first appeared.
• Per-app rules + a global default -- Add rules for specific apps, or set one global rule that applies to everything else.
• Quit app when last window closes -- Optionally quit an app after the last window closes. For annoying apps like Quicktime and TextEdit that keep running in dock, even with no windows.
• Reopen History -- Recent closures appear in the menu bar with one-click reopen.
• Suggestions -- A built-in catalog proposes rules for common apps (Finder, Preview, QuickTime, messaging apps, and more).
• Pause -- Pause all closures from the menu bar: for an hour, until tomorrow, or until you resume.
• Menu bar app -- See upcoming and recent closures at a glance. The icon can be hidden in Settings.
• Safe by default -- Squeegee sends a normal close (the same as clicking the red button), never force-quits anything. Never overrides "Do you want to save?"
• Local and private -- No network access, no accounts, no telemetry. Data never leave your Mac.

How It Works

1. Add a rule -- Pick an app and choose how long a window can sit idle before Squeegee closes it.
2. Squeegee watches -- It tracks each window's last-active time (or opened time) in the background.
3. Stale windows close automatically -- When a window passes its deadline, Squeegee closes it, just like clicking the red close button.

Rules are setup per app, and applied per window.

Permissions

Squeegee needs the Accessibility permission to see and close windows of other apps. The app prompts for it on first launch. Nothing leaves your Mac -- the permission is used only to close windows locally.

Optionally needs permission to control Finder. With it, you can re-launch Finder windows to the exact path they were on when they were closed. Without it, it launches to the default directory.

Requirements

• macOS 15.0 (Sequoia) or later

Install

1. Download Squeegee.dmg.
2. Open the DMG and drag Squeegee.app to your Applications folder.
3. Open Squeegee and follow the onboarding to grant Accessibility access and pick your first rules.
