Macbook, no. Mac, yes. It's all I've ever used aside from my console.
Steam? No. Direct-from-developer and GOG (DRM-free)? Yes.
Be aware that Elder Scams Online doesn't support Mac anymore. That news dropped a couple years ago and you will have problems on any newer Macs. Heard there are workarounds, but for that game? Whether it is worth the trouble is debatable. Ever since monetization started driving the ship, well... I have some very personal stories I can share about that but I'll leave things there since that isn't really what this thread is about. Just... be careful.
