Overview

RetroMac is a macOS menu bar app that overlays live CRT, VHS, LCD, and classic operating-system themes on top of your screen. It is designed to give the entire interface a retro look without changing your apps, files, or system settings.

The app supports whole-screen effects, single-window targeting, and per-display control, so you can decide how broadly the shader applies. It also includes classic desktop recreations such as Windows 98, Windows XP, Mac OS 9, Mac OS X, BeOS, and Snow Leopard, along with docks, boot splashes, and some built-in retro-style widgets and games.

RetroMac is free to download and use, runs on macOS 14 and newer, and is described as a universal binary for Apple Silicon and Intel Macs. An optional one-time Pro upgrade unlocks extra shader presets, custom presets, and the webcam shader.

Features

Live retro shaders

Run more than 30 live CRT, VHS, LCD, and classic-computer shaders in real time on top of your screen. The effect is applied instantly without restarting macOS.

Classic OS themes

Switch the whole interface to period-style themes such as Windows 98, Windows XP, Mac OS 9, Mac OS X, BeOS, and Snow Leopard, including docks, desktops, and boot splashes.

Per-display and per-window control

Target the effect to a full screen, a single display, or just one window. Per-app rules let one app stay sharp while another gets the retro treatment.

Performance-aware rendering

Use built-in eco modes that reduce shader load on battery power. The app is positioned to stay responsive on modern Macs and on Apple Silicon hardware.

Virtual webcam output

Use the virtual camera output in Zoom, Google Meet, Teams, or OBS. The download page says it supports iPhone Continuity Camera and USB webcams, plus lower-third overlays.

Deep customization

Customize intensity, colors, icons, dock style, and per-app or per-display rules. The source also says you can import your own Metal shaders and build custom presets.

Use Cases

  • Whole-screen retro look

    Apply CRT or VHS shaders to an entire desktop when you want the whole Mac to look like an older display or tape playback setup.

  • Focused window effects

    Style only a single app or window so an editor, emulator, or browser can get the effect while the rest of macOS stays normal.

  • Mixed-display setups

    Give a multi-monitor setup different looks on each display, which is useful when you want one screen clean and another screen heavily themed.

  • Retro gaming and emulation

    Run retro games or pixel-art emulators through scanlines, phosphor masks, and NTSC-style effects to change the presentation without altering the game itself.

  • Camera and stream output

    Send a CRT-styled feed into Zoom, Meet, Teams, or OBS using the virtual camera for calls, recordings, or streaming.

Pros and Cons

Pros

  • Applies retro effects live on top of the existing screen content instead of replacing apps or files.
  • Supports multiple scopes, including whole screen, single window, and individual displays.
  • Includes both shader effects and fuller operating-system themes, giving more than one style of retro look.
  • Supports per-app rules, making it possible to keep some windows clean while styling others.
  • Runs on macOS 14+ and is presented as a notarized universal binary for Apple Silicon and Intel Macs.

Cons

  • The pricing page is unavailable, so the source only clearly confirms the free download and the one-time Pro upgrade summary.
  • Some advanced capabilities, such as custom presets and webcam shaders, are tied to the paid Pro unlock.
