switch2mac 0.4.2

Free up space, and see what's in your game files. Download switch2mac-0.4.2.pkg below, or let the app update itself if you already have 0.4.1.

New

• Settings › Storage: shows what building leaves behind on your Mac (each game's build files, engine copies no build uses) with their sizes, and one Clean up button. Your games, saves, settings, the shader caches your games keep, your dumps and your keys always stay; the next build of a game only takes longer.
• The Build page shows what's in your file: the update or DLC inside an .nsp, a card image or a .nup, or in a dump folder, read from the file's plain table of contents (nothing is decrypted).
• 133 more Switch games have pages with nxnative's tested build, shared shader lists and reports (these reach the app without an update).

Fixed

• An opened game case could get stuck and ignore every click while a game ran.
• Builds from the app stopped with "run ./switch2mac.py setup first" (already fixed for 0.4.1 through the app's own update of its build tools).

Installing

1. Download switch2mac-0.4.2.pkg and open it.
2. macOS says it could not verify the installer (switch2mac is not signed with a paid Apple Developer ID): click Done, open System Settings → Privacy & Security, scroll down and click Open Anyway.
3. The installer puts switch2mac in your Applications folder. You only do this once: the app updates itself after that.

The zip below is what the app's own updater installs; to install by hand, use the .pkg.

You need a Mac with Apple silicon and macOS 26 or later, Xcode with its Metal Toolchain (Xcode 27 for games built with nxnative's newest code), and the .NET 10 SDK; the app tells you what is missing. Switch games also need your own prod.keys, dumped from your own Switch.
