Consoles are dying and PCs are replacing them. Like the original commenter suggested, people want to run PC games. The market has decided that the benefits of compatibility outweigh the added complexity. On the PC you have access to a massive expanding back-catalog of old software, far more competition in the market, mods, and you're able to run whatever software you want alongside games (discord, teamspeak, game streaming, etc.).

Macs are personal computers, whether or not they come from some official IBM Personal Computer compatibility bloodline.
