RetroMac wraps your everyday macOS in the look and feel of classic computers: authentic CRT shaders over your whole screen, themed docks and desktops (Mac OS 9, Windows XP/98, BeOS, Amiga…), retro widgets and games, and a virtual webcam that pipes the CRT look into Zoom, Meet or Teams. Open source, free to use with an optional one-time upgrade for extra presets and webcam support.

RetroMac turns your modern Mac into a live retro machine: CRT, classic Macintosh, VHS, Game Boy and more. Apply 30+ shader presets to your whole screen or a single window, swap your Dock for classic Mac and Windows looks, and capture themed screenshots. Free with optional extra presets.
