omacosy is a pre-1.0 tiling desktop environment for macOS, inspired by omarchy, built and tested on macOS 26 / Apple Silicon. It features a real Super key via Karabiner, dwindle layout through AeroSpace, a themed status bar, focus-follows-mouse, trackpad workspace swipes, and a live workspace overview. The entire setup idles at approximately 157MB of RAM and consists of AeroSpace, Karabiner, and five small self-built Swift binaries. Created by paulsp94, it aims to replicate the omarchy experience on macOS without compromising SIP security.

The project emphasizes transparency around permissions, listing every grant required including Accessibility, Input Monitoring, Screen Recording, Bluetooth, Location, Automation, and Files and Folders access. Each permission enables specific functionality — for example, Screen Recording powers the workspace overview thumbnails, while Location only retrieves the Wi-Fi network name. Users are informed exactly what breaks if they refuse any grant.

Installation is handled via a single script that symlinks configs, installs Homebrew dependencies, compiles helper binaries, and starts services. An update script pulls changes and rebuilds only modified binaries. The system is idempotent and includes backup and uninstall manifests for clean removal.

While currently tested only on an M1 Max MacBook Pro, the design generalizes across hardware. Feedback is welcomed, particularly regarding performance and smoothness.
