Spectacle
Spectacle is a free, open-source window management utility for macOS that lets you snap, resize and reposition windows using keyboard shortcuts. It enables rapid window arrangement — for example, sending the active window to the left half of the screen, maximising it, or moving it to another display. It was widely adopted by power users, developers and professionals seeking efficiency gains from keyboard-driven window tiling, particularly those coming from Linux or Windows environments. Spectacle sits in the menu bar and intercepts customisable hotkeys to perform window operations without requiring dragging or mousing.
AI Recommendation
1 suggestionSpectacle has been abandoned — the project stopped receiving meaningful updates before Apple began enforcing app notarization, and there is no native Apple Silicon build shipped by the developer. You can confirm this by checking the official GitHub repository, which shows no releases or commits in years. The Intel-only binary still runs under Rosetta 2 today, but Apple is removing Rosetta in macOS 28 (late 2027), so Spectacle will stop working entirely at that point. The active community has moved to Rectangle, a free, open-source successor written in Swift that runs natively on Apple Silicon and provides nearly identical window-snapping functionality. Rectangle is notarised, actively maintained, and imports Spectacle-style keyboard shortcuts during setup so the transition is straightforward. If you prefer a polished commercial alternative, Swish is a paid option with additional features. Both are native Apple Silicon apps and will continue to work past 2027.
