The MPS (metal performance shaders) support will be possible once Slicer provides a native arm64 build for macOS as then the embedded python in Slicer will appropriately be an arm64 version that can use the arm64 macOS torch whls that provide the MPS support.

For now, macOS on Slicer must continue to use the intel x86\_64 version that runs through the Rosetta 2 layer.

Once arm64 support is available we will post over on the following thread to provide an update:

> PyTorch has support for using the shaders in the M series chips, but to use it, one has to use the arm64 version of Python. Should a native (in this case, M3) build of Slicer3D be possible? If yes, where should I get the 5.15.2 Qt package (for MacOS arm64)? Thank you! Gene
