Pretty unlikely as long as Apple refuses to support Vulkan. Even if they did, the whole Proton project is about Valve controlling their own destiny rather than being chained to someone else's platform, and Apple is just another Microsoft in that regard.
Couldn't Apple spend their resources on that? Proton is open-source, and Apple's the one with the incentive to have more "prestige" AAA game devs to parade around during keynotes.
Apple could but they're not interested in non-native games, they want native ports or nothing. As I discussed a few posts over, Apple went to the trouble of developing a DirectX compatibility layer, but then told game developers they're not allowed to use it for anything besides evaluating whether their game would run well enough on Mac hardware. If they go ahead with a port then Apple still expects them to do it all the hard way.
It's textbook "perfect is the enemy of good" because yeah, compatibility layers have overhead, native is better, but if you insist on native everything but can't get devs on board then you just end up with no games.
Compare Steam Machine (2014) to Steam Machine (2026). The difference this time around is Proton support, and you can pretty easily see the hype on the internet for the new version, even after the original version was mocked relentlessly in some circles for having "no games."
Well, some games like Civ V still manage to work! But they actually had to port it to 64-bit, otherwise it'd have the fate of all other 32-bit macOS games unfortunately...
Also, how could Apple kill the old software that is better than the new, if it doesn't control the emulation? This way they don't have to even have 10% of the features to force you to buy again.
I think they are also absolutely addicted to cruddy pay to win mobile games and they don’t want to give up that sweet drip feed of IAP that they get a 30% cut of… which is substantial.
For funsies, try searching App Store apps and find a way to filter out results for apps with IAP. Nope!

Apple thinks PC games are for gross nerds and would rather not sully their fashion image by associating with gamer any more than is absolutely necessary. So no, Apple won't be doing that.
Every few years at WWDC they'll make some mention of some upcoming new gaming features. A couple years ago they showcased that their new iPhones could run the latest Resident Evil game. Hell, they brought out Kojima one year to announce a Death Stranding port for Mac.
The efforts are usually short-lived and mostly fruitless, but I wouldn't say they're "grossed out" by gaming nerds.
It would make sense, but Apple has large amounts of disdain for people having fun with their products. This evidenced by the large amounts of engineering they've put into very large, capable, and efficient GPUs, only to squander them on rendering web pages and liquid glass.
They released Apple Vision Pro with no ability to play popular PC games on it.
That's great as long as it works, but D3DMetal is a proprietary, closed-source Apple library so you can and probably will get rug-pulled by Apple neglecting or deprecating it as their priorities change. They've only ever positioned it as an "evaluation environment" for developers to estimate how their game will run before going ahead with a native Mac port, not as something for end-users to play Windows games with, so if developers don't bite then they'll have no reason to keep working on it.
Right now, the user experience with Crossover is that you have to manage the whole thing of installing Windows Steam in a Wine bottle, then installing games within that second Steam installation, then dealing with the fact that Steam doesn't seem to like having two instances running on the same computer (my native Steam loses connectivity every time I start the Crossover instance).
Wanting Proton on Mac isn't about that specific fork of Wine, it's shorthand for wanting the user experience that Valve gives you on Linux.
As a comparison, before proton, you could run steam with wine under linux. Wine directx implementation was sufficient to make a quite a few games work just fine, but the experience was atrocious. You either had to install a new instance of steam per game or install everything under one bottle which didn't work well as you had to tweak the install per grame. Personally I used it just for one or two of games that I really wanted to play and could actually run outsisde of steam after installation.
As far as I understand, there's actually an intermediate driver on macOS that implements Vulkan on top of Metal, similar to how Proton implements Direct3D on top of Vulkan.
The available low-level API is Metal, and the existing software stack is written for Vulkan, so it makes more sense to implement Vulkan than to write a new Metal backend.
Every day I sit down at a Mac for work and proceed to launch VS Code, Zed, Outlook, DBeaver, Excel, Teams, LogSeq, Syncthing, Chrome, Firefox, LM Studio and Docker. I prefer MacOS but basically all of my application workflow exists for Windows verbatim and if using browser versions of the MS apps, on Linux too.
Same! I main macos, love the hardware, but I keep a very close eye on Linux (asahi, omarchy etc) in case Apple gets any more toxic, and I am forced to jump ship to something else, and that something else won't be windoze.
The last straw with MacOS was when my US bank cards expired, I could no longer update apps I already paid for, I could no longer install apps I already paid for. Everything was held hostage, could not install FREE apps via the appstore on macos or on ipad.
That day my eyes opened to what Apple has become.
You simply cannot trust Apple with your computing future. They're a fashion company now.
and plus one here!
I don't know, I like my mac workflow but irritation and aggravation have crept in more frequently of late. Last week I was told a binary that clang++ had just produced from my own code could not be run because Apple couldn't check whether it was safe..
And what to make of power users complaining bitterly about Tahoe & liquid glass etc?
I'm hanging on to Ventura for now.
Apple is big enough to not need gaming and their philosophy is to have the most control possible on their ecosystem and to be the most closed possible. For them it makes no sense to encourage steam to be big on mac (except as a way to jumpstart their own system before closing it). And it is especially true now that steam is making machines, so is a direct competitor
I mean, theoretically they could backport the D3DMetal wine driver from the Game Porting Toolkit. Also I remember there was some early preliminary work done on stock wine a few years ago.
Honestly right now there is so much overlapping between all the wine "flavors" and forks available (Stock wine, Crossover, Proton/Proton-GE/Wine-GE, Game Porting Toolkit, winevdm, probably a few more I'm forgetting right now) I'm not entirely sure how many features have been independently implemented already multiple times.
I believe that was part of the original plan for Proton, but with the success of the Steam Deck that got shelved and it moved to a focus purely on Linux.
I don't think it's ever likely to return any time soon, but it'd be cool if it did. Valve seemingly have very little interest in macOS at the moment.
CodeWeavers work closely with Valve and the Wine project to improve compatibility with games, and Apple's own Game Porting Toolkit is based on CodeWeavers work on Wine too. So all the pieces are there in theory.
Proton is just a fork of Wine that also translates from Microsoft's DirectX graphics API to the native graphics API of Linux (Vulcan) so you can run Windows games on Linux.
The new thing Proton is adding is translation from x86 to ARM.
Macs already have Wine, an x86 to ARM translation layer (Rosetta), and an Apple provided translation layer from Microsoft's DirectX to the Mac's native Metal graphics API (D3DMetal) which is integrated into upstream Wine.
I mentioned elsewhere — Right now, using Wine/Crossover is a hassle. Wanting "Proton on Mac" isn't about that specific fork of Wine, it's shorthand for wanting the user experience that Valve gives you on Linux.
But honestly at this point I’m destined to buy a Steam Machine despite having a hefty Mac that could do gaming if only it were possible. Valve have been amazing about open computing and Apple are basically the enemy at this point.
It makes me wonder about what using steam machine for all computing might look like, as the new home of open computing and gaming.
