ActiveSilicon cards (phoenix and lfg) do not work with 10.10 mac os. In the system menu Mac OS do not recognise it. It recognised by catalyst software (except lfg), in start up logs, but when try to initialise it, an error occurred. Also catalyst software do not recognise normal mac os and video cards. I got 10.10 mac os with dual D700 cards summary 12gb vram, catalyst says that i has 10.9. mac os and 4gb vram. But in start up log when diagnose pci e line its seems to be ok with hardware. Also Status bar of graphic card always 100 percent under mac os 10.10. with all version of catalyst (m466 n525 n541).
Decklink QUAD recognised by catalyst like 4 device.
