Hello shuhung,

Tried the replacement mentioned with 10.14.5 beta 3 bundles and kexts (AMD drivers and AppleGVA frameworks):

No more iTunes DRM movies working! Removed dummy141.kext, no difference. Tried HEVC10.14.1.kext, then Ellesmere.kext, no difference!

So at last, I've replaced the beta 3 AppleGVA frameworks with the 10.14.4 ones (without replacing the AMD drivers) and iTunes movies working again...?

This is with an MSI Radeon RX580 8g v1 and iMac 14,2 SMBIOS. Whatevergreen not tried as I remember it crashed iTunes when it was there (10.14.0 and 10.14.1). I also have an AMDRadeonEllesmereGVA.kext that I didn't tried...

What's up, I'm at lost!

Thanks,

Patrice
Thanks, You saved me!
I put all your kext in my CLOVER / Kext / Other
My CPU is calm now for 4K video play backs!

Try each one separately to see which one solves your problem. They are not meant to be used together usually.

@shuhung: why the dummy kext isn't working anymore with 10.14.5 beta 3 and the AppleGVA frameworks? Could it be modified in some way to prevent the replacement with 10.14.4 frameworks and iMac 14,2 SMBIOS?

Thanks,

Patrice

It work but meaningless, IOGVA already enabled by Radeon kexts on 10.14.5 beta 2 up, no relevant to AppleGVA.framework.

You can replace AMD kexts from beta 2/3 and skip AppleGVA, replaced AppleGVA from beta 2, because it match beta 2 AMD kexts, have better transcoding performane on Davinci than without AppleGVA replacement, work very well for R3 + RX570 + 10.14.4 + iMacPro1,1.

SMBIOS iMacPro1,1 should work well with HSW/SKL/KBL, but is the bad choice for SNB and IVY.

I don't use SMBIOS iMac14.2 on Mojave, no advantage for me, no comment.

In fact, I use dummy kext on 10.14.1 to 10.14.4 only to enable DRM iTunes playing. I don't need to encode or decode. So, following you, encoding is enabled without dummy but unfortunately, DRM iTunes is broken and dummy kext doesn't help this time (any other way to bring back HDCP content?), hence my question.

Oh, and I guess iMacPro SMBIOS is not a good choice in my case neither (Haswell).

Thanks anyway,

Patrice

Dummy kext enable IOGVACodec support, when IOGVACodec set to AMDU6V3 then HW DRM decoding work.

IOGVACodec already enabled but DRM broken is another issue, no relevant to dummy kext.

If beta 2/3 kexts not help, just restore original kexts and apply dummy kext, waiting for next release.

(any other way to bring back HDCP content?
Edit: have you try reset DRM configuration, see below link
