I ran the upgrade from Sierra to High Sierra, but now I'm unable to get past the "gIOScreenLockState 3" or "Failed to initialize graphics firmware" during boot up. I tried following suggestions from several articles on Tonymac86 and other websites, but still unable to make any progress.
I'm starting to get the feeling that the Asus GeForce GTX 950 graphics card is incompatible with HighSierra??
Anyone else successfully using this card?
On the contrary, my other problem is that when I remove the graphcs card I'm still unable to boot my system. In that case I get to the apple logo and suddenly my monitor goes black and appears to lose its signal. Thoughts???
Any suggestions would be much appreciated. Getting desperate here for a solution.
