DockDoor
DockDoor is a macOS utility that adds live Dock previews, Alt+Tab-style switching, and quick window controls while keeping the built-in Dock.
What is DockDoor?
DockDoor is a native macOS utility for people who want faster window switching and more context from the built-in Dock. It enhances the standard Dock with live previews of open windows, keyboard-driven switching, and quick actions such as close, minimize, and quit without replacing the Dock itself. Users can hover over app icons to inspect open windows, move through previews with the keyboard, and customize layouts, gestures, and shortcuts to fit their workflow. The app also adds extras such as compact list view, calendar previews, media widgets, and multi-display Dock locking for users who work across several screens. DockDoor is published by Ethan Bills and is available for modern versions of macOS on both Apple Silicon and Intel Macs.

Safety overview
Status: Mostly safe
DockDoor is a legitimate macOS utility, but it needs powerful permissions such as Accessibility and Screen Recording to show previews and control windows. Those permissions are consistent with its purpose, yet they give the app broad visibility into on-screen activity, so it is best installed only from the official DockDoor sources. The developer specifically warns that unofficial reuploads and cracked copies have included malware or unauthorized modifications.
Recommendation: Keep DockDoor if you use its Dock previews, keyboard switching, or window controls regularly. If you no longer want those enhancements, you can remove it and revoke its Accessibility and Screen Recording permissions in macOS settings. Only reinstall it from the official DockDoor website if you need it again.
