bfgminer not detecting GPU

[galaxie5000]

Hello,

I have installed bfgminer 3.9.0 on a Mac with homebrew. It can't detect the Radeon 5750 GPU:

[2014-01-04 11:53:41] CL Platform 0 vendor: Apple
 [2014-01-04 11:53:41] CL Platform 0 name: Apple
 [2014-01-04 11:53:41] CL Platform 0 version: OpenCL 1.2 (Aug 24 2013 21:03:27)

This is a s far as it gets. Trying to add with 'all' says no devices found.

Prior I had an earlier version of bfgminer that I compiled, and at some point I got it to detect the GPU ok, but then I was getting other errors and bfgminer would randomly quit.

I removed the compiled version, and running only the brew version, it can no longer detect the GPU.

Any ideas?

Thanks.

Do you have OpenCL (not GL) drivers installed?

I believe they are built into OS X 10.9. And the output appears to indicate OpenCL 1.2, no?
