Update: we spent the last few days analyzing the problem and could pin down the code that does cause the crashes on 10.10.3/10.10.4. However, that code does nothing special and still works fine on other platforms, including OS X < 10.10.3. We tried to work around the issue but couldn't yet find a working solution. We notified Apple about the problem so we have to wait and see how they handle it. We'll continue to look into this ourselves but at some point our possibilities will be limited...

Have you tried on 10.11 El Capitan? If not .. I can, if you wish .. although I need to set up a test case because I can't get work anymore on the Mac.

Would be nice.
BM:
Enable Beta App versions and you should get work.
Good luck!

I can test 10.11 in July (public beta). It's more than just the buffer. I tested a lot of variations and workarounds but to no avail. It's also not just an AMD driver issue as a NVIDIA Quadro 4000 is also affected. I'm seeing a number of issues, even when I "fix" the buffer transfer issue, which makes me think that OpenCL itself is buggy since 10.10.3. Apple is informed...

FWIW we (volunteer computing community) are not the only ones facing show-stopping problems with OpenCL on OSX that can't be solved at our end.
Here's an article summarizing the criticism from Paolo Ciccone (LuxRender) and Ton Roosendaal (Blender): Open source devs criticise Apple’s OpenCL support, referencing Ciccone's open letter to Tim Cook: OS X users unite!.

Thank you for the updates and your continued efforts. I know I am not alone in hoping for a solution so I can resume making more than just a token contribution to the project.

Yep, we found that as well in the previous beta already. Seemingly our connections to Apple paid off to some degree. We also have a workaround at hand that would work with El Capitan in case Apple doesn't fix the problem entirely. We're still in contact with Apple to get the issue fixed for good though...
Stay tuned,
