Hey! So when you're building for Mac in Unity, you should be able to specify the architecture you want to target. This is found in the build settings. See Unity docs, first section titled "Target architecture": https://docs.unity3d.com/Manual/macos-building.html you want to make sure you target both Intel 64-bit and Apple Silicon (the silicon option is for M1 chips). This way you can ensure your game will run on Macs built after November 2020. Cheers!
