I also noticed that Nvidia actually announced CUDA 6 yesterday (for whatever reason not on their own blog ...), but no SDK or OS X drivers yet. The R330 Windows/Linux drivers have support for it though.
What's the device id and revision id of your card? And can you make a BIOS dump and upload it? I wasn't aware of any chip changes in the GTX 780 line, but they might have started using the same revised chips that they're also using for the GTX 780 Ti (GK110B).
I'm also annoyed by the 10.9.1/10.9.2 situation. I did expect a release this week, but maybe next week then ... On another note: CUDA 6 will be released soon (maybe at SC13 next week?), so I also expect new drivers from Nvidia (probably R330 if they had to do the same changes/additions like they had to on Linux/Windows).
@any mod who's reading this: could splice the last few posts into the GTX 780 thread (#125 onwards)? Because this really doesn't belong here. And then close this thread, because there is nothing more to say since 10.9.
I don't know about Clover, but in chameleon I have to disable the "GraphicsEnabler", otherwise I wouldn't even get to the login screen. But since it's working fine if I disable that option, this obviously means the card is supported as-is by OS X (full EFI support I guess?). Does Clover have a similar option? And yeah, if OpenCL doesn't work properly, you're screwed, because CoreImage uses it - so about _everything_ in OS X.
I'm using the MacPro5,1 profile btw, but this shouldn't make much of a difference.
