This is due to Apple's development of its Metal framework which, in their eyes, is the obvious choice for anyone developing for the GPU in OSX.

Clearly, Apple has no interest in providing sufficient support for OpenCL.

Additionally, it is impossible (as far as I know) for users to update these drivers in OSX. Notice here that, despite the fact that OpenCL has been released up to version 2.2 as of 2018, Apple devices come with drivers only up to version 1.2. You should now be able to include in all of your XCode OpenCL projects. Return to Recovery Mode and enter csrutil enable in a Terminal if you wish to reenable SIP and restart again. Move your cl.hpp file to /Applications/Xcode.app/Contents/Developer/Platforms/atform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/amework/Headers. Open a Terminal and enter csrutil disable to disable SIP. Restart your system and hold cmd+R to launch OSX in Recovery Mode. When activated, it will prevent adding the header to the OpenCL framework even with root access. There is one complication: Since OSX 11.11 (El Capitan), Apple has started using something called System Integrity Protection (SIP) to prevent the naive or overly-adventurous from doing too much damage. It is possible to add cl.hpp to the system framework so that you do not have to manually add it every time you create a new project.

Download and compile this example code, mostly copied from this tutorial, to test your system. Do not forget to actually link the OpenCL framework under the project settings in XCode. Simply add and include this header file in XCode OpenCL projects and it should work fine. I would like to use C++, however.ĭownload the appropriate cl.hpp file from the Khronos OpenCL Registry.

Unfortunately, it does not come with a header file for C++ bindings if you want to use C alone this should not be a problem. The OpenCL framework in OSX is stored at /System/Library/Frameworks/amework/. I am using OSX 10.13.4 (High Sierra) and XCode 9.3.1. Here are some instructions to get started. I've recently started learning OpenCL for my work at DESY CFEL and found that setting up a C++ environment in XCode for OpenCL is not an entirely straightforward task.
