I had posted here already about having the same flickering problem that others with ATI based video cards are having, but I have a little more information now, that may give someone smarter than me a clue as to what's going on. I'm using a Radeon HD6670 card, and have been using it with dual monitors since day one with no problems until this update. I discovered yesterday that if one of my monitors was disconnected, the flickering went away! I also noticed that with both monitors connected, under System Information/Hardware/Graphics/Displays both monitors showed they were using 30 bit color; with only one monitor connected, it showed 32 bit color, just as it should. After seeing the post about SwitchResX, I downloaded it and gave it a try. Sure enough, after setting each monitor to millions instead of billions of colors, no more flickering....and System Information is showing 32 bit color for both monitors. Just to add to the insanity, I tried an old NVidia GT440 card I had laying around---black screen, both monitors, no matter what. I tried both the native drivers and the web drivers, nothing worked. Anyone got ay ideas, comments or suggestions?

I have two monitors as well however disconnecting one didn't fix the problem. I confirm however that both displays are shown as having 30-bit color in the System Information. Using DisableMonitor and switching to 32-bit color fixed my problem and now both displays are shown as 32-bit color depth in System Information.
 
Yes I am, should I remove it? Also please note about my clover, Unibeast 7.1 does not work correctly, so i am using unibeast then Clover 4035 to reinstall EFI.

Why are you using MacBook1,1 SMBIOS on a Desktop? Needs to be iMac 14,2. The whole config is a mess. You have a lot of garbage in drivers64UEFI needs to be cleared up. AppleImageCodec-64.efi, AppleKeyAggregator-64.efi, AppleUITheme-64.efi, FirmwareVolume-64.efi, SMCHelper-64.efi need to be removed. Replace VBoxHfs-64.efi with HFSPlus.

Again all that was installed by clover 4045. Following directions now.

What should I do about OsxAptioFixDrv2?

Replace OsxAptioFixDrv2 with OsxAptioFixDrv. Config needs to be cleaned up better still create a new one.

Ok I am recreating a new Unibeast USB. I want to find out the issue of why I can't boot from before. I have mounted the EFI before had to make sure Unibeast does not fail at mounting and install the bootloader.

Keep going! :)

As @violetdragon says, you probably need to start with a bare config.plist to get the system up and running. Don't worry about sound and USB 3.0, don't worry about serial numbers (you can always re-use your previous one etc)

If you have a UniBeast 7.0 stick, boot with it but don't choose the Sierra drive, instead boot to the UniBeast "External" volume. When the install screen comes up, don't go further, go to the Tools menu at the top and run Terminal. Then try copying the UniBeast config.plist over to your main Sierra drive using Terminal commands.

You will get there in the end :)
