Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

Try with the FamilyGw's modded kext from post #484

https://www.tonymacx86.com/threads/...t-support-hevc-hw.240353/page-49#post-1857103

Disable your iGPU in BIOs.
Add the modded kext to Clover/Kexts/Other
Run this command in terminal "sudo update_dyld_shared_cache -force"
Reboot
Im using Vanilla AppleGVA.Framework from "now" 10.14.2.
Netflix works flawless in Safari again, and I have HEVC and H.264 encode and decode working

iGPU disabled. Tried the kext unmodified (with 0x67DF1002 IOPCIMatch) and rebuilt the dyld cache: no go...
Replaced IOPCIMatch in the plist of the kext with the id of my card (0x67FF1002): no go...

**Inserted 0x67FF1002 in the Baffin section of HEVC.10.14.1.kext: no go...

There should be a way to circumvent the broken AppleGVA? Are you using an RX 560 too slipanot?

Just chiming here...

Since 10.14.1, if I do not replace AppleGVA.framework with the 10.14.0 version, no more iTunes DRM downloaded movies playing.

Tried with the HEVC.10.14.1.kext, no luck. Added WhateverGreen 1.2.8 with boot args "shikigva=32 shiki-id=Mac-031B6874CF7F642A", no luck...

Gigabyte Z97X-UD3H and MSI Radeon RX560 BTW...

Thanks,

Patrice

What worked for me is the use of the dummy kext ( attached) in clover/kexts/other and/or replace the AppleGVA.framework ( attached ) in S/L/Frameworks.
You'll need to rebuild the DYLD cache after replacing the AppleGVA.framework:
sudo update_dyld_shared_cache -force
I also used the tools attached to clean Kext cache & NVRAM as a final step.

Im using a Gigabyte Auros RX580 8GB model. That may be the issue.
Give the attached modded kext a try.
Same install steps

Thanks, will try it tonight... going to work in a few minutes.
I notice that ones having success have RX 580, you're right.

I'll try the kext of slipanot and yours too tonight... and report back.

dummy141 kext should work with RX4XX/5XX (tested both IDs 0x67DF1002/0x67FF1002 work) without replacing AppleGVA.framework on 10.14.2

Pls upload your ioreg file.

Ok, maybe that encoding work but it doesn't matter for me and there's no way for me to verify (don't need it). iTunes DRM downloaded movies playing doesn't work with the following:

- update to 10.14.2 with;
- HEVC.10.14.1.kext injected

Maybe my SMBIOS (iMac 14,2)? Anything else?

Even injecting latest WEG did nothing to help.
Attached ioreg with HEVC kext injected.

Would a RX 580 solve this problem? I have one local not too expensive.

Thanks,

My bad, what was needed was "dummy141.kext", not "HEVC.10.14.1.kext".

Working fine now!!! Yesssss!

Thanks a bunch, I know that it wasn't a real showstopper to use old framework but I prefer this method.
