Kitsmith / Utilities / OpenEmu
A free, open-source multi-console emulator for Mac that organizes your ROMs into one unified, box-art library — NES, SNES, Game Boy, Genesis, PS1, and more.
Our take
The easiest on-ramp to console emulation on Mac: drag a ROM in and OpenEmu identifies it, files it under the right console, and pulls in box art automatically, rather than making you configure a separate emulator core by hand. Built on top of many individual open-source emulator cores (Nestopia, Genesis Plus GX, Mednafen, and others) unified under one Mac-native interface. Requires macOS 10.14.4 or later and games you already own.

Worth knowing: Emulates the consoles it supports (Atari, Nintendo, Sega, Sony PlayStation, and others up through PS1/PSP-adjacent systems) — does not include or provide ROM files, which you must supply yourself from games you own.
