More than that, the combined Mac userbase is smaller than PS3, and only slightly larger than Xbox360, and would require targeting multiple hardware platforms, including different CPU architectures and various GPUs, with non-standard graphics APIs. As a game dev, I would struggle to target MacOS over even Linux with the Steam Deck now becoming available.
