Hold Option and press Tab, and the thumbnail list appears with a size you set yourself. AltTab Pro gives macOS a keyboard-driven window switcher that shows live previews for every open window—not just one icon per app. The shortcut is configurable to almost any key, so it sits neatly beside the built-in ⌘-Tab and Mission Control without clashing.
Cycling individual windows instead of apps
The standard ⌘-Tab cycles applications. AltTab Pro cycles individual windows. That means a browser with five open tabs and a detached PDF viewer show up as separate thumbnails you can reach in one keystroke. It complements the Dock for launching and Stage Manager for grouping—it handles the moment-by-moment task of jumping straight to the one window you need.
What it replaces in a typical workflow
It replaces hunting through Mission Control or right-clicking a Dock icon to pick a window. Dragging a file over a thumbnail while switching windows works the same way it does in the Finder. The preview size, icon zoom, and title text are all adjustable, so the overlay looks right on any display from a laptop screen to a studio monitor. VoiceOver support, Sticky Keys, and reduced transparency are built in.
A technical writer juggling a style guide, a draft, and feedback in a browser usually keeps all three in separate windows. With AltTab Pro, one shortcut surfaces every window as its own thumbnail. No more right-clicking the browser icon and guessing which tab holds the review comments. The blacklist quietly removes helper apps that never belong in the rotation.
Equal-weight windows versus sidebar or menu-bar rivals
AltTab Pro follows the alttab pro macos pattern of giving every window equal weight in the switcher. Contexts and Witch take different routes: Contexts leans on sidebars and search, while Witch stays closer to the menu-bar model. None of them match this app’s thumbnail-first approach for quick visual scanning. For users who think in windows rather than applications, mac alttab pro remains the most direct fit.
