I have an RX 580 8gb. Could someone walk me through where to find the AMDRadeonX4250.kext and how to install it?
Final Cut X version 10.4.8 - HEVC Hardware Acceleration Not working
Final Cut X Version 10.4.6 - Working
Same goes for Compressor and Motion...new versions don't have acceleration, previous versions do
You can still render in the new versions, they're just painfully slow without the hardware acceleration
YesOK thanks.
I assume you are using macOS 10.15.4 ?
Let me add to it that HEVC works with 10.4.8 when iGPU is ENABLED in the bios. Even if you use smbios which don't use iGPU i.e. iMacPro1,1. iGPU doesn't get utilised though, dGPU handles everything. But it has to be ENABLED in the bios.Final Cut X version 10.4.8 - HEVC Hardware Acceleration Not working

Due to this I had to spend extra and buy i7-9700k instead of i7-9700kf. >.<
dGPU is always primary.Could you clarify as to whether you configure the IGPU in BIOS as primary or secondary,
and whether you configure the IGPU as headless, for each SMBIOS that you try?

I do nothing special. In fact, I don't even set a frame-buffer or use any DSDT patches related to graphics. I let WhateverGreen handle everything and make sure that there are no clashes. In bios though, I set the memory allocation to maximum number possible. In my current machine it's 64 and in previous one it was 128.Thanks, I couldn't make acceleration work on FCPX 10.4.8 when the iGPU was enabled using Mac 1,1. Any special settings you used? Which OS are you on?
I tried 19,1 as well without success. But I was also having boot freezes unless I changed the platform ID to headless while iGPU was active. And I'm not sure I was using the right one.
It all gets a bit confusing and I may need a few drinks while I sort it out.
For reference, HP8300CMT i5-3470 RX570 is used.Thanks, I couldn't make acceleration work on FCPX 10.4.8 when the iGPU was enabled using Mac 1,1. Any special settings you used? Which OS are you on?
I tried Lilu+WEG and iMacPro1,1 with my i7-3770K and FCPX 10.4.8 still uses the CPU to encode HEVC 8-bit with and without IGPU enabled.dGPU is always primary.
With iMacPro1,1 & MacPro7,1 iGPU frame-buffer makes no difference. It's same be it headless or otherwise.
With iMac17/18/19 etc. if iGPU is enabled and headless then iGPU & dGPU both are used for acceleration. Never tried with non-headless frame-buffer with these smbios.
