As I think about this, I don't think there's one single answer.
Here's my current opinion as it evolves.
- M1 macs, only now have a decent gpu, but most macs out in the wild, i.e., pre-M1 do not.
- Also consider the actual Mac marketshare. Only about 10 to 15% of PCs - it is rather small.
- Apple/Mac's reputation for not being a good gaming machine (deservedly so)
- Apple's marketing, they continually promote the mac for professional users.
So as I see it, we have a computer manufacturer that for decades seemed cold and resistant to having games on its platform. Only just recently have they equipped their models with a decent gpu, but yet still market their products for professional users so its safe to assume a majority of their current marketshare is not hugely interested in gaming.
So put yourself in the shoes of a game publisher, you only have X dollars to spend to publish a game and of that x dollars you can dedicate y dollars to exploring new markets.
Do you put those dollars towards the Nintendo switch which means you have a pool of about 100 million potential customers or the mac which sold 7 million units last quarter. And of those 7 million sales, how many were for professional users vs. consumers willing to buy games?
Publishers won't really consider the mac as a gaming platform because Apple itself doesn't.
