OpenCL never saw the success it needed, and like the other vendors, Apple has essentially rolled GPU compute into their graphics API. Nearly a decade ago, Apple was the big supporter of OpenCL, kickstarting the whole initiative. So once the deprecation becomes a removal, the only graphics and compute API supported in the Apple ecosystem will be their proprietary Metal.Īs an aside, this announcement goes for GPU compute as well as graphics.
And while the other vendors have rallied around (or at least supported) the successor Vulkan API, Apple has not.

OpenGL ES in particular will run on every Mac, iOS device, Android device, Windows device, and Linux device.

Which means that with the loss of OpenGL support across the Mac and iOS ecosystem, so too will go support for the only truly common cross-platform graphics API across the industry. So Apple’s threats are generally credible: if these APIs are being deprecated now, then they likely aren’t going to be available much longer. The company has already excised 32-bit apps from iOS and is in the process of doing the same for macOS, despite the number of applications (and games!) that will break. And now by deprecating support for these older APIs, Apple is signaling that they are reserving the right to remove them entirely in the future.Īnd unlike other OS vendors who may keep deprecated APIs around for years (if not forever) in the name of backwards compatibility, Apple has proven it has no such qualms. Instead, Apple has been pushing developers to Metal almost as soon as it became available.
Apple never added support for OpenGL ES 3.1 or later on iOS, and similarly macOS doesn’t go beyond OpenGL 4.1 (Khronos is up to 4.6 now). Instead, Apple is strongly encouraging developers to use their proprietary Metal API, which has been available for a few years now.Īpple’s lack of interest in Khronos’s Open APIs has not gone unnoticed over the years. Listed in the developer release notes for both iOS and macOS, Apple is deprecating support for what are now their legacy graphics and compute APIs: OpenGL, OpenGL ES, and OpenCL. As has long been the story at One Infinite Loop, what Apple giveth is what Apple taketh, and Apple’s latest rendition of OSes is going to be no exception.
