[GUIDE] iMac19,1 / iMacPro1,1 i3-9100 RX-580 and DRM

[miliuco]

Nothing special. Only this steps:

• iGPU disabled in BIOS (also removing any related to iGPU code in config.plist)
• Lilu and WhateverGreen
• iMacPro1,1 or MacPro7,1.

How did you check hardware acceleration?

Try Black Magic RAW test (App Store) >> 8K 12:1. Tell me the GPU scores.

Spoiler: Scores

You can download the monitor app - XRG to see if the iGU is being used for hardware acceleration.
Anyway, I've changed back to a iMac19,2 since it does give me iGPU functions as well as nearly doubling the GeekBench GPU score

Yes, iMac19,2 gives GeekBench higher scores than iMacPro or MacPro but you loose DRM (TV app or Safari Netflix and others).

I don't use those apps - that said, going to https://dortania.github.io/OpenCore...ml#testing-hardware-acceleration-and-decoding and clicking the testing links, my iMac19,2 build plays all the DRM test just fine - and I get better GeekBench scores too.

I'll be sticking with this iMac19,2 build for the time being. Thanks too for your replies.

Congratulations! TV app and Safari Netflix or Prime Videos only works with iMacPro or MacPro on my system.

@aussiemartin
Do you have iGPU disabled in Bios with iMac19,2?

No - it's enabled because I want to use it

Thanks, I'll try it because I always had tried iMac19,1.

if I use iMac19.2 , can I play apple music in 24bit 192khz? IGPU only use to computational acceleration

I guess you can but I haven’t tried. Try and comment.
