Describe your problem

Valheim just released on MacOS today. Source

On Apple Silicon (arm64) hardware, the game launches an arm64 binary. It is still built with Mono as evidenced by the usual Mono directories in the app bundle.

It appears that the Mac builds of BepInEx are all for Intel x64 platform.

Proposed solution

Please provide builds of BepInEx for MacOS arm64, or create a Universal Binary. If you create a UB, then all the .dylib files for BepInEx will internally have both an Intel x64 build and an Apple arm64 build in the same file.

A Universal Binary will be easier for users, as they just have to download "the Mac version" and not worry about which architecture their game is running. Some Unity games only ship Intel x64 binaries, but others run natively on arm64 on Apple Silicon.

This game is getting significant exposure at WWDC 2024 and may appear in the Keynote. Mods with BepInEx are very popular, therefore you can expect to see many, many requests for this until it is implemented.
