Show HN: Omacosy – Omarchy-style tiling desktop for macOS, no SIP
Published: 2026-08-21
omacosy omakase + macOS + cosy. An omarchy -style setup for macOS: tiling window management with a real Super key and Hyprland's dwindle layout, a themed status bar written for it (bar, popups, sliders and screen dimming in one process), focus-follows-mouse, trackpad workspace swipes with a Mission-Control- style workspace overview (live previews included), focused-window border rings, and unified theme switching down to the wallpaper — bootstrapped from this one repo. The whole desktop environment idles at about 157MB of physical footprint — what Activity Monitor calls Memory — across WM, bar, three background daemons, the swipe daemon and Karabiner. Resident set size reads ~322MB, but RSS counts each process's share of the same shared system frameworks, so footprint is the honest figure. Measured on this machine docked to a second display , largest first: footprint RSS omacosy-overview 36MB 46MB omacosy-bar 32MB 55MB AeroSpace 24MB 85MB Karabiner (4 processes) 24MB 61MB omacosy-borders 19MB 29MB aerospace-swipe 13MB 22MB omacosy-ffm 10MB 24MB A second display is not free: the bar and the border overlay each draw per-screen, and AeroSpace carries a second workspace set. On one display the same set measured ~155MB. The dwindle daemon used to be on this list; the split direction is decided by a short omacosy-helper run on focus change now, so nothing resident does it. These figures move with uptime, so treat them as a band rather than a constant. omacosy-overview is the swing:…
