Follow these instructions exactly:
Common mistakes:
- You must have ARM architecture (any of the M-series chips)
- Blender must be downloaded from Blender.org (not elsewhere) and not portable
- Your privileges are limited (give Blender/Terminal elevated priviledges)
- You have conflicting ffmpeg, colmap, or rembg brew/pipx installations (clear these and reinstall)
- You must refresh Blender after installation
