Just curious, but what system definition are you using?

18,3

I've heard of others trying to use the 19,1 or that it came up automatically but I didn't see it as a viable offering when I did my clover install ? Only thing that seems terribly off is my actual boot times take 15-20 seconds of the apple logo screen, with my old 6700K it booted in 6 seconds flat.. Would love to hear if others have seen this or how they fixed it..

Have you booted with -v to see what is stalling your boot?

This is what I would try to see if it does anything.
Remove "SSDT/DSDT", and only keep "fake smc kext". Disconnect all drives except OS X drive. Install latest Whatevergreen/Lilu kexts.

See if it makes any difference.

Under macOS it runs perfect and works fluid in ALL Adobe apps and Davinci Resolve. I can't say the same for nVidia cards as I had issues with them in High Sierra.

Overall very happy. I just wish it ran cooler on stock speeds. You can barely touch the thing when it's at 80% load.
Awesome news. I have a 1080 and since the latest driver updates it is borderline unusable.

One question about your setup. I was about to get the FE for 10-bit display in photo and video apps on a Z370/i7-8700K. I have been reading conflicting reports on whether Vega 64 supports 10-bit (or only under DirectX like Nvidia). Do I need the FE or is 64 good for 10-bit?

Most modern cards support 10bit color and so does macOS.

You need a 10bit display tho.

For example, I do a fair amount of video/photo color correction and I still use a real Mac display (27" Apple LED display @1440p). It is an 8bit display but photos look very good and I know what results I'll get since I've been using this display for a long time even previously on a real Mac.

Afaik, if you do find a real 10bit display that you want to use, it should work fine under macOS.

Thanks, @izo1 .

I had read that all supported 10-bit DIrectX, but not always OpenCL. Good to know.
I do have 10-bit displays (BenQ SW320 and Ben SW2700P).

Now, I just have to find a card. Still leaning toward the FE, though. :)

Well the good thing is Apple uses Metal now. Other companies need to adapt it tho. If you check the graphics settings in photoshop there is a new Metal option. Not sure about Lightroom etc.

Here’s an older article about El Capitan supporting 10bit color, so by now many apps and macos has full support.
