Kitsmith / Utilities / RetroArch
A free, open-source frontend that runs dozens of individual emulator "cores" — NES through PS2 and beyond — through one unified interface, on Mac and nearly every other platform.
Our take
Not a single-console emulator like OpenEmu but a frontend/launcher for the Libretro project’s many emulator cores, which trades OpenEmu’s simpler onboarding for far broader system coverage and deep configurability (shaders, netplay, rewind). Native macOS 10.13+ builds are available directly or via Steam; older Intel Macs have a separate legacy build.

What it does
Many cores, one app
Dozens of individual system emulators run inside a single unified interface.
Shaders & rewind
CRT-style shaders, instant rewind, and fast-forward.
Netplay
Online multiplayer for supported cores.
Cross-platform saves
Save states and configs are portable across RetroArch’s many supported platforms.
The deal
- Free and open source
Worth knowing: Steeper setup than a single-purpose emulator — cores (one per emulated system) are downloaded and configured separately inside RetroArch’s own interface. Also available on the Steam and Apple App Store storefronts with a more limited feature set to comply with those platforms’ policies.
RetroArch — questions people ask
Is RetroArch free?

Does RetroArch work alongside a notch app like Alcove?
