Given how closed the Apple ecosystem is, I highly doubt it will ever be taken seriously for games ever again.
The reason why Apple will never be taken seriously as a gaming computer is that, but also they use mobile GPU's in most of their desktop and laptop models now.
I've been struggling with this whole thing because I'm getting fed up with Windows 10 and am nearing the point of having to buy a new gaming machine. The biggest games on my horizon right now are WoW: Legion and Overwatch. Overwatch will never work on a Mac (at least Blizzard says they have no intention of creating a version for OSX for right now specifically because of the use of mobile GPU's in Macs solely), and
will probably never work properly using WINE on Linux. I'd be willing to buy a new computer with Windows 10 if I could pay to remove all the privacy-breaking stuff (that seems to somehow get reset every couple of updates to Windows on my system). Linux isn't a viable option for gaming right now, it's trying to be but is struggling.
So I'm at a point where I buy a Mac and buy a TV and PS4 for gaming. Or I feel like I've sold my soul and get a Windows 10 box (or worse put Win 7 on it and risk MS pulling security update support for the OS). Or I buy a Mac and give up the only hobby I have in gaming.
Apple's ecosystem is too closed for me, but -- and maybe this is more of a false sense of security -- I feel safer using an iPhone and Apple products because they are just easier to use for the most part despite being closed as well as the decent quality of hardware that Apple is known fore. I convinced my parents to buy an iMac and iPhones begrudgingly while I was still on the Android and Linux bandwagon and I've seen how much easier (compared to Linux) and more secure (compared to Windows) the system has been for them. For the most part, everything my parents do on their Apple products just works out of the box with very few minor issues. Granted, some design decisions are frustrating and Apple is not without it's flaws, but (and I feel dirty saying this) I trust Apple more than I do MS).
If I had time to tinker, I'd build my own badass desktop PC and put Linux on it and tinker with WINE to get all of the games I play working on it and be done. But I've been down that road before. The whole reason why I switched from Android to iPhone last year was because I was sick of tinkering and just wanted something that worked. I found that in an iPhone and now I'm entirely immersed in the Apple ecosystem and have come to embrace it. The same thing happened to my brother-in-law, who was even more of a diehard Android guy than I was and actually enjoys tinkering.
I've longed for the days when we'd finally be able to play any game on any modern computer OS, but it's stuff like this that MS is doing and the move by Apple to only use mobile GPUs that just moves us further away from that ideal. Steam tried, and still is trying, to get games to be OS agnostic but it's been an uphill battle. There are still very few big name games that release for Linux that actually run well and even fewer release for OSX. Most of those same games are also released on console.
So, I guess after 10 years of never using a console, MS is pushing me away from Windows and back on to one because they decided to give their OS away for free at the expense of user privacy and this UWP thing. This is not good for PC gaming or gaming in general. Sure it's great for gamers that have an Xbox and a Win 10 box, but not great for devs that don't want to use UWP.
