The honest state of Mac support today, and what is coming to 3D Mate.
Hunyuan3D-2 is Tencent's high-detail image-to-3D model. It is powerful but heavy, and its reference code is built for NVIDIA GPUs, so there is no simple way to run the full pipeline on Apple Silicon today. Here is the honest state of Mac support, the memory it wants, and how 3D Mate is bringing it on-device.
The pipeline has a shape stage and a separate texture stage. Both are large and CUDA-oriented, and the texture pass is especially memory hungry.
Running the official code on a Mac means porting its CUDA components to Apple's MLX or PyTorch MPS, or renting a cloud GPU. There is no first-party Apple Silicon build.
Even ported, the geometry pass wants around 24 GB of unified memory and the texture pass around 48 GB, so it favours a high-memory Mac.
Hunyuan3D-2 is the most demanding engine here, and today it does not run natively on a Mac without a substantial port.
Hunyuan3D-2 is coming to 3D Mate as a Mac-native, offline engine. Until then, TRELLIS.2 4B (balanced) and TripoSG (sharpest geometry) run fully offline on Apple Silicon today and cover most needs.
