After a successful instal and launch of the normal osmosdr_fft when attempting to launch with the gr-fosphor graphics acceleration I receive errors and the python app window appears without FFT and will closing. In Terminal i see this error:

I use a imac i7 3,4Ghz with 32GB RAM and 4GB Nvidia GTX 780. OS = El Captain. Osmocom-fft and other HackRF stuff running fine. Any hints? I thougt my imac should capable of OpenGL flawless...
