MacOS

Unfortunately there is no official MacOS release.

To build Meshroom on MacOS, you should follow the precise explanation from Ryan Baumann on his blog

Read this issue for a more up to date guide https://github.com/alicevision/AliceVision/issues/1071

To fully utilize Meshroom, a NVIDIA CUDA-enabled GPU is recommended. Without a supported NVIDIA GPU only "Draft Meshing" can be used for 3D reconstruction.

Note: CUDA 10.2 (Toolkit and NVIDIA driver) is the last release to support macOS for developing and running CUDA applications. Support for macOS will not be available starting with the next release of CUDA. https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html

Apple ditched Nvidia support, so new Macs don`t have a Nvidia GPU and even NVIDIA eGPUs are not supported since MacOS 10.14 (Mojave).

In the future, Apple will switch to ARM CPUs, which will add an additional issue for building, so an official MacOS build becomes even more unlikely.
