Turn your Mac into a time machine.
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.
