Anyone using Final Cut Pro 11 Magnetic Mask with Z790 motherboard?

[Brian Huether]

Hi, I have

Asus Z790 Proart
14700K
6950 XT
Sonoma 14.7
iMacPro1,1 SMBIOS
OC 1.0

I am noticing glitches in magnetic mask. The analysis seems to go fine, but if I use the brush tools to modify the mask, each brush stroke gradually erodes the whole mask.

Also, after hitting Done to finish the mask and extract the subject, if I then place solid background below, say white, then I see that background come through the entire subject a little bit, as if the whole mask is partially transparent. That is, even though the mask looks black, it is partially transparent.

Here I show what I mean:

I don't see any info from Apple suggesting magnetic mask doesn't work with intel and on apple community site intel users say it works fine. But since I have hackintosh, maybe something is just not working. So trying to see what others are experiencing and if there are known workarounds.

My 6950 XT GPU works fine, it produces around 270000 in Geekbench metal. In FCP settings it shows GPU as "AMD Radeon HD GFX10 Family Unknown Prototype". No idea if that suggests anything. I have always seen that, and in Geekbench it also shows that as the GPU, but the GPU works fine in any apps that use GPU, renders in FCP are indeed using the GPU, hardware decoding works. So all seems fine.

Ideas?

thanks

Hi, ok, here is save from IOregistryExplorer.

I posted about this on reddit and someone thinks maybe it has to do with FCP 11 expecting a T2 chip.  But the apple release doesn't say anything about that.  It says apple silicon is recommended for magnetic mask, but not required.  

One thing I do notice regarding GPU is that FCP sees it as "AMD Radeon HD GFX10 Family Unknown Prototype".  I wonder if there is something about me spoofing my 6950 XT that is at play here, though various GPU benchmarks all show the GPU metal working just fine.

 

thanks
