RetroMac

RetroMac is a menu bar app that makes your Mac look like it's stuck in 1985—or 1998, or 2001, depending on which flavor of nostalgia hits different. It drops CRT glow, VHS tracking errors, Sony Trinitron color bars, or full-blown classic Mac OS visuals over your screen in real-time. Want your whole display to hum like a tube TV? Only got it. Want just one window to look like a Game Boy? RetroMac does that too—pick from 30+ presets or build your own.

The app started free, still runs free for the basics, and if you want the premium shaders, webcam effects, or custom presets, it's a one-time €8.88 buy. No subscription, no nonsense. It also bundles a Game Mode with DOOM, Wolfenstein 3D, and Commander Keen—because nothing says "authentically retro" like fragging demons through a CRT filter. The founder built this for the love of old hardware, and honestly, that's exactly the kind of weird passion project the tech world needs more of.
