# Can the Mac Dock show window previews when I hover, like the Windows taskbar? By Mahad Kazmi, developer of Superdock. Updated 3 September 2026. Short answer. Not by itself: hovering a Dock icon shows the app's name and nothing else. Two apps add Windows-style thumbnails. DockDoor overlays previews on Apple's Dock, and Superdock replaces the Dock with one that previews windows natively, filtered to the Chrome profile you are hovering. ## What a preview should tell you The point of a hover preview is to pick the right window without clicking through. A good one shows every window of that app as a live thumbnail with its title, lets you click a thumbnail to go straight to it, and offers close and minimize without changing focus. For a browser it should also tell you which profile a window belongs to, because five Chrome thumbnails with the same favicon do not. ## Superdock previews - Hover any tile. After a short pause a plate above the dock lists that app's windows as thumbnails with titles. - Hover a Chrome profile tile and you see only that profile's windows. - Click a thumbnail to bring that window forward. On a multi-display setup, each dock previews the windows on its own screen. Live thumbnails use Screen Recording, which is optional. Without it, previews show window titles and the app icon. ## Or add previews to Apple's Dock If you want to keep Apple's Dock exactly as it is, DockDoor adds hover previews and an Alt-Tab switcher on top of it and is free for the core features. What it cannot do is change the Dock's tiles, so Chrome profiles stay merged. ## Frequently asked questions ### Why do I need Screen Recording? macOS treats a thumbnail of another app's window as a screen capture. The permission is optional and only unlocks the images. ### Do previews work for minimized windows? Yes. Minimized windows are listed and clicking one restores it. ### Can I turn previews off? Yes, from the menu bar menu (Window Previews) or in Settings. Download free The dock is free. Chrome profile icons: 14 days free, then $7.99 once. macOS 14 or later. ## Continue reading - [Superdock vs DockDoor](../compare/superdock-vs-dockdoor.html) - [How do I Alt-Tab between windows on a Mac like Windows?](alt-tab-between-windows-on-mac.html) - [Can I have a separate Dock icon for each Chrome profile on a Mac?](separate-dock-icon-for-each-chrome-profile-mac.html) Source: https://superdock.app/answers/dock-window-previews-on-hover-mac.html Superdock: the dock is free to download; Chrome profile icons are $7.99 once after a 14-day trial. https://superdock.app/
