Somewhere in Kyoto, a Nintendo lawyer just spilled their matcha. A new open-source project called Nxnative lets Switch games run on Mac, iPhone and iPad, and around 85 titles already work with it. The list reads like Nintendo’s greatest hits: Mario Kart 8 Deluxe, Super Mario Odyssey, The Legend of Zelda: Tears of the Kingdom and Dragon Quest XI S: Echoes of an Elusive Age.
What makes this one sting is how it works. Nxnative isn’t a classic emulator that slowly translates one console’s brain into another’s. The Switch runs on an Arm-based Nvidia chip, and Apple’s current devices also use Arm processors. That means much of a game’s original ARM64 code can run directly on Apple silicon. Nxnative fills the gaps by faking the Switch’s Horizon OS services, including thread scheduling, memory management and file access, and turns the graphics into Apple’s Metal API. Think of it as Wine for Nintendo: a compatibility layer that makes a game think it never left home.
The result should need far less horsepower than traditional emulators, which is exactly why iPhones and fanless MacBooks are suddenly in the conversation. For a company that guards its software like Bowser guards a princess, that’s not a fun headline.
It gets better, or worse, depending on whose side you’re on. Nxnative borrows code from Ryujinx and Yuzu, two Switch emulators Nintendo effectively shut down in 2024. Yuzu’s developers settled a lawsuit for $2.4 million, and Ryujinx disappeared months later. Seeing their work resurface inside a tool aimed at Apple’s billion-plus devices is the kind of sequel Nintendo never greenlit.
Performance is a mixed bag. Most games run at their original Switch frame rates, so Mario Kart 8 Deluxe zooms along at 60fps while Tears of the Kingdom sticks to a wobbly 30fps with regular drops. Some titles support higher frame rates and render scaling, though others still show graphical glitches.
This isn’t plug-and-play. Each game must be built into an unsigned IPA or .app using the command line, Xcode 27.1 and Homebrew, although a separate community app called NX2Apple adds a friendlier interface. The developer, seedds, stresses that no game files are included and the project has no Nintendo affiliation. Players need to dump games from their own Switch.
Then comes the real plot twist. A fork of Nxnative has already booted the Switch 2’s Mario Kart World on a Mac, reportedly the first Switch 2 game running outside Nintendo’s hardware. A console barely into its life is already leaking. Nintendo hasn’t commented, but given its track record, the countdown to a legal response feels like it’s started.
