I have been mining with sgminer and 7770 GPU with 10.9.1 with no problems. The 10.9.2 update seems to have broken sgminer, when I launch the application inthe terminal, screen anomalies appear, and eventually the window manager crashes. Could this be some kind of frame buffer issue? I do not have a monitor plugged into the 7770, it is plugged into the integrated intel 4000. The 7770 appears in the system profiler, however I have never tried to plug a monitor into it.
Any insight would be appreciated.
