Download the first Blender 2.75 Release Candidate now!
The first release candidate for Blender 2.75 has just been released. You know the drill – there are probably still bugs in it, so please test and report any issues you may find.
We are finishing work on a massive 2.75 release. The official Release Candidate is available now! Please help testing it and report issues to the bug tracker.
Among new features are AMD OpenCL rendering and stereo/multiview support!
In User Preferences -> System, I have only CPU Compute Device.
I use Mac Pro with Gigabyte R9 280x graphic card.

Similar problem to Filip re: MacPro
AMD FirePro D700 6144 MB
CPU Compute is the only available option in User Preferences > System
No idea if this will still work, but back in 2013 I got my ATI card to work with Blender 2.68 (I now use an Nvidia card so can’t test). Here is what I did:
(also keep in mind I’m a PC guy…you may have to adjust this for a Mac…or maybe it won’t work at all?)
1. Most current drivers for GPU
2. Open command prompt and type “set CYCLES_OPENCL_TEST=all”
3. In that same command prompt window head over to your blender directory and start Blender
4. Now (hopefully) in Preferences –> System you can set your compute device to OpenCL and under that I had set mine to “Pitcairn” (this will be based on your GPU)
5. Switch to cycles
6. On the render tab switch the device to GPU Compute.
Keep in mind, this worked way back in 2013! So might be of no use now, but I hope it helps.
I know this trick. After I did it, I could set GPU, but it chrashes. Command line says that: OpenCL Build failed.
Cool! When I tested an earlier version my graphics card was slower than my CPU, but now my Graphics card is faster!
