Apple M1 Max vs CUDA on chest analysis pack

You are using SlicerTotalSegmentator?

I have detailed some development work that is required to get full MPS support working and needs a developer to help champion this work:

Also note that Slicer only provides x86_64 binaries, so on macOS you won’t be able to utilize latest PyTorch since the torch developers dropped support for x86_64. This means things may still not be optimized for your system. Building Slicer native arm64 builds for macOS is work still in progress by the Slicer developers.
