GoKawiilDeveloper ports classic Mac OS to Nintendo Wii hardware
A developer using the handle Rairii has gotten classic Mac OS, including versions 7.6 and 9.2.2, to boot on the Nintendo Wii's desktop, after beginning the project on June 22, 2025. The work involved porting OpenBIOS to emulate the Open Firmware environment required by the classic Mac OS 'Trampoline' bootloader, building on Rairii's earlier experience porting Windows NT to PowerPC Mac hardware with similar ArtX-designed chipsets.
GoKawiil's interpretation of the reporting above, not reported fact.
The project is a hobbyist feat rather than a commercial release, but it demonstrates how shared chip lineage between Apple's older PowerPC Macs and Nintendo's GameCube, Wii and Wii U consoles can let retrocomputing enthusiasts revive legacy operating systems on unrelated consumer hardware. Rairii explicitly notes the work was done without coding agents or LLMs, framing it as a manual learning exercise, which suggests the broader retro-software scene still values hand-done reverse engineering over automated tooling.
- Classic Mac OS 7.6 and 9.2.2 have been booted to the desktop on a Nintendo Wii.
- The project relies on porting OpenBIOS to replicate the Open Firmware needed by Mac OS's Trampoline bootloader.
- The developer says the work was done entirely without AI coding tools, started June 22, 2025.
Nintendo Wii Console — This whole retro-hacking adventure centers on breathing new OS life into the Wii's ArtX-designed PowerPC chipset, making an actual Wii the perfect companion for following along or tinkering yourself. Owning the real hardware lets you appreciate just how impressive it is to see Mac OS booting on a console never meant to run it. It's a fun piece of gaming history that doubles as a hacker's playground.
