I'm running OS X 10.7.5, 2.5 GHz i5, 16GB Ram, Radeon HD 6750M. Your new version of GUI Miner does not detect my GPU with the error message "No OpenCL devices were found" however the older version of GUI Miner that was built for Mac 2012-11-18 version does detect my GPU and works fine for mining.

Thanks for the feedback, looks like the core isn't working properly, can you please download the new poclbm package (they made some Mac OS relevant changes since the last package) here:

and unzip that poclbm.app then right click my guiminer.app - show package contents, then go /Contents/MacOS and replace the poclbm.app there with the new one, and let me know how it goes? I haven't integrated that into my guiminer yet as I'm cutting my hosting limit fine as it is!

One thing though - the 2012-11-18 one is my guiminer and the 2011-x-x version is the old one - was that a typo or is it actually mine that's working for you? Or it's MacMiner that's saying No OpenCL ?
