Mac Pro 5,1 (10,8 10,9)
The "reboot in OS X" Bootcamp function has suddenly stopped . This is a vital function for me, because I cannot reboot my Mac using "Option" button (I'm using for a long time already GTX 670 graphics, due to which the menu is not displayed even when the screen is off, same as it was with Radeon 5870) .
I've installed the old EFI graphics (GTX285) to fix this problem, but I tried everything and in a result I took 2 CLEAN HDDs and installed Mac OS then Windows 7 and then few times more with different versions of Mac OS, different versions of Bootcamp utility (blaming 5th version). Doesn't helps. Pressing "Reboot in Mac OS"- Mac again reboots in Windows OS. According to existing conditions the only possible way to reboot in Mac OS is by resetting PRAM. And so is till the moment I need Windows. SMC resets also. I even replaced battery today, because the problem is most likely in hardware field. So where is the bug? Guess it can only hide in PRAM? PRAM reset silves the problem only once.
I equally need Mac OS and Windows, I want everything as was before.. HELP!
P.S. I was thinking probably Windows has installed some insidious update, but I've installed the system
from original DVD-10.6.3, and from old fvd Windows 7 using an ild Biotcamp utility-version 3. But still, the problem had not disappeared.
