Cinch
Cinch is a window management utility for macOS that lets you snap and resize windows using mouse gestures. By dragging a window to the left or right edge of the screen, you can snap it to fill exactly half the display side-by-side with another window. Dragging to the top edge maximizes the window fullscreen. It's designed for users who prefer a mouse-driven approach to window management and workspace organisation, complementing keyboard-centric tools like SizeUp or TwoUp from the same developer.
AI Recommendation
1 suggestionCinch has been discontinued by its developer and there is no native Apple Silicon build. According to the Roaring Apps compatibility database, this app is flagged as end-of-life and no longer receives support. While Cinch continues to run under Rosetta 2 today, it will stop working entirely when Apple removes Rosetta from macOS 28 in late 2027. If you rely on Cinch's snapping behaviour, consider moving to Rectangle (a free, open-source window manager that runs natively on Apple Silicon and offers similar mouse and keyboard-driven snapping), Magnet (a paid Mac App Store option), or the built-in Stage Manager feature in macOS Sonoma and later, which provides window grouping and snap zones without requiring a third-party utility. These alternatives are actively maintained and will continue working after Rosetta 2 is removed.
