    Yesterday at WWDC 2018, Apple revealed macOS Mojave, which is set to bring users a Dark Mode, redesigned Mac App Store, organizable Stacks, streamlined screenshots, and more when it launches wide in the fall. Alongside the new features, Apple has confirmed that it is deprecating OpenGL (Open Graphics Library) and OpenCL (Open Computing Language) in favor of Metal.

    This means that apps built using OpenGL and OpenCL will still run in Mojave, but they will no longer be updated after macOS 10.14 launches. Apple encourages games and "graphics-intensive apps" built with OpenGL to adopt Metal ahead of Mojave's launch, and apps that use OpenCL for computational tasks "should now adopt Metal and Metal Performance Shaders."

    Rise of the Tomb Raider: 20 Year Celebration is one of the latest Mac games to run on Metal


    Launched four years ago, Metal is Apple's own 3D graphic and programming interface that combines the functions of OpenGL and OpenCL under a singular API. In explaining the move of deprecating the "legacy technologies" of OpenGL and OpenCL, Apple said that "Metal avoids the overhead inherent in legacy technologies and exposes the latest graphics processing functionality" of GPUs found in devices across iOS, macOS, and tvOS.

    Although Apple's decision to deprecate the older technology in favor of its own graphics API may not be surprising, some game developers have begun criticizing Apple for the move, particularly how it affects the future of gaming on Mac. Notably, OpenGL is an open-source, cross-platform solution that made it simple for developers to build games on both Mac and PC at the same time, providing some parity to a platform that many have agreed is lacking as a gaming hub.

    Since "many games and apps continue to use OpenGL," particularly those that released prior to Metal in 2014, the shift to Metal-focused development is leaving Mac developers worried about any potential to grow as a gaming platform (via PC Gamer). Game developer Sam Loeschen tweeted that he feels "conflicted" about the decision, calling Metal a "really, really good" graphics API but admitting that "this decision alienates macOS further as a gaming platform."

    Speaking with PC Gamer, game designer Rami Ismail said that while "it's not doomsday," it appears that Apple is preparing for such an occasion in regards to fully terminating OpenGL/OpenCL on Mac. He explained that for now, "the worst that's going to happen" is that parts of old apps will "break," and pointed out that lacking a single cross-platform graphics API is a "pain" and "not very good for developer confidence" in Apple.
    More developers and programmers chimed in on the news to PC Gamer, including Alex Austin, who ultimately said that while he likes to develop on Mac to "support fans if I can," he's most likely "not going to spend any time on Metal because Macs are a pretty small percentage of the market and really probably not worth it even now."

    Why do some think old technology should be supported forever? At some point you have to cut it loose. If you require it, then don't upgrade. Sorry kids. This is how the world works. Even Honda doesn't support your '84 Civic with new parts like fenders anymore.

    Isn’t Metal already the only way to have graphics-intensive games on iOS?

    OpenGL in itself isn't old though. It's just that Apple hasn't updated it past 4.1. But OpenGL keeps getting updated regularly.

    Regardless, to tackle the cross-platform API issue, we have MoltenVK. It's not a single API at the backend, but it solves the issue somewhat. And a lot of games use middleware like Unity and Unreal, and they can handle the API calls.

    Isn't OpenGL on the way out anyway? I think Vulkan is the successor.

    No we don't. That is like telling a programmer to write in C instead of Java.

    Apple really does not care about gaming apparently. Every game I've run in metal so far has been a disaster.

    The thing is, there's a lot of software out there that is well-supported and being used on Macs right now, that uses OpenGL. A good example is Second Life.

    Some developers may decide that it's not worth the effort to port their code to Metal, since Metal is only used by Apple. Thus they will just discontinue Mac support.

    We are going to lose software on the Mac platform because of this.

    When have Macs EVER been good for gaming?

    You guys are forgetting that Apple is creating a unified program for developing apps on the iOS and macOS. There are many metal games on the iOS that can now easily come over to the Mac.

    You've just got to abandon the old school way of thinking how Mac games are made.

    Who cares about iOS games for the Mac?

    You ever tried running a blizzard game in metal? Starcraft is the worst of the bunch. Nearly unplayable with graphical glitches. I went back to OpenGL after seeing how bad metal was. The game devs don't support it the same.

    As usual... did you read the post? They explained why.

    Care to elaborate on this? My understanding is that both Metal and Vulkan are low level, so this analogy seems inaccurate.

    Blender is all OpenGL / OpenCL. Was going to buy an eGPU to increase Blender performance but now it looks like I should move to Linux or Windows instead. This truly sucks. :-(

    C, Vulkan, DX12, and Metal are low level.

    Java, OpenGL, and DX11 are high level.

    Although it would probaby be a bit more accurate to compare OpenGL and DX11 to C++ and something like Unity 3D to Java.

    Eff Metal. Vulkan exists to be cross-platform as one single low-level API and works on macOS as well, just not officially supported by Apple because they have to be ******s about it.

    Maybe this move is related to an Apple-designed GPU for future Macs? Apple is already using their own GPU design in the iPhone.

    Typical apple fashion take the walled garden approach, simply not worth being on a Mac any longer. Innovation cannot come from just one company people.

    They can ban all 3rd party graphics libraries for all I care. As long as it brings iOS apps & games to the Mac faster.

    I don't understand why Apple can't support OpenGL/CL and Vulkan alongside Metal.

    It's fine for iOS, where developers are used to doing things Apple's way and only Apple's way, but the desktop is a whole other beast.

    Although my first reaction was to upcoming ARM-based Macs, this mirrors my thoughts, as well. Since I'm not a gamer, I can pretend that this won't affect me, but I think it portends Macs that feature lower power consumption.
