Hi, I am on SMBIOS MacPro 6,1. I just upgraded to 10.14.6. I was previously running my display just fine after using this patch:
Code:
            <dict>
                <key>Comment</key>
                <string>AppleGraphicsDevicePolicy (board-id) Patch (c) Pike R. Alpha</string>
                <key>Find</key>
                <data>
                Ym9hcmQtaWQ=
                </data>
                <key>Name</key>
                <string>AppleGraphicsDevicePolicy</string>
                <key>Replace</key>
                <data>
                Ym9hcmQtaXg=
                </data>
            </dict>

Since I upgraded, the display will not work after boot, and I am forced to use the iMac 14,2 config which has difficulties doing JPEG previews for example. Any idea what I need to do to get the display to work again under MacPro 6,1? Thanks in advance.

According to your profile you should not. NVIDA is not supported on Mojave. That’s it.

How can that be I have been on Mojave all year with NVIDIA. I am on Mojave now just under SMBIOS 14,2. The only problem is this profile, the JPEG images do not preview in Finder. @telepati - can you suggest another patch? Thanks.
Mojave has Apple drivers for old Kepler Nvidia cards (your GTX 650 Ti and my GTX 680, as well as earlier 700 series). High Sierra is the last to support Maxwell (750, 750Ti, 900 series) and Pascal (1000 series) (requires Nvidia web drivers which don't exist for Mojave). RTX is not supported by any macOS.

Please note, that METAL is not working on those older NVIDIA cards properly. Yes, you might have picture, but you cannot use cards properly for various tasks, that require GPU.

The best option on case of using Mojave - buy a proper AMD video card!

What's a simple test that shows this problem with METAL? System Information.app shows "Supported, feature set macOS GPUFamily1 v4". GFXBench Metal appears to work well.

Hi
I've been trying to setup my Nvidia Card without success I have tried almost everything I can't get the web drivers to load, could be that changing the GFX0 to GFX1 help?
It looks like the Card its not recognized...
