Honestly it doesn't matter. The whole "Macs can't game" has no basis in facts. The goalposts are continually moved.
To give some examples of arguments.
- Not enough games for it. There is actually more games in the Apple store than most other gaming stores. You can also play a lot of iOS games now.
- The majority of games are terrible. The majority of games in other stores are terrible too (sadly).
- It can't play [insert PC game]. Neither can a Nintendo switch but that doesn't mean it can't play games.
- I can play [insert PC game] but doesn't count because it's too old. You can't win on this one.
- It's not a real game unless it uses a GPU. There are countless games out there that don't meet this requirement.
Really the only argument for Macs not being gaming machines is that the majority of buyers do so not to play games on it, but to get stuff done.
Anyone who can afford a Mac is likely to have at least a console and/or PC Gaming rig.
