Splatapult wont compile on Apple devices due to lack of support OpenGL, and OpenXR. It might be possible to use Apple's Game Porting Toolkit to get it running, but I haven't tried it.
Alternatively, I would suggest the MetalSplats project for viewing 3DGS files on a Mac, as it supports the Metal graphics API directly.
