I tried 10.14.5 Beta 2 on a test drive. Netflix no longer works.

Disable IGPU and use only DGPU.

I am using only dGPU. On my main drive with 10.14.4, it is working just fine.

Hello, I built my first Hackintosh and wanted to use only the GPU. I've read through everything here and implemented that way. Everything is displayed correctly in the system.









Only I can not export in Final Cut (H264) and the VDADekocerChecker gives the following error message:

An error was returned by the decoder layer. This may happen for example because of bitstream/data errors during a decode operation. This error may also be returned from VDADecoderCreate when hardware decoder resources are available on the system but currently in use by another process.

VDADecoderCreate failed. err: -12473

I've made the following settings in Clover:

Graphics: FB name Orinoco, Inject ATI
Clover / Kexts 10:14: Lilu, WhateverGreen, dummy141

The IGPu is disabled in the bios.

Who knows what the problem could be?

Try it with smbios iMacPro1.1

or
boot flag shikigva=32
and shiki-id=Mac-7BA5B2D9E42DDD94

That's normal.

Your options are:
1. Enable IGPU in BIOS, Inject->Intel=Yes, and use connector-less ig-platform-id=0x01620007. Or,
2. Change SMBIOS model type to iMacPro1,1. But you will get green glitches in the H.264 output. Or,
3. Keep your SMBIOS as-is and add boot flags: shikigva=32 and shiki-id=Mac-7BA5B2D9E42DDD94. Or,
4. Wait for MacOS 10.14.5 update

I use Option 1 at the moment with my i7-3770K until Option 4 is available.

You have not stated what SMBIOS model you are currently using.

Thank you very much, I was using the SMBIOS iMac 14.2.

2. Change SMBIOS model type to iMacPro1,1. But you will get green glitches in the H.264 output.
3. Keep your SMBIOS as-is and add boot flags: shikigva=32 and shiki-id=Mac-7BA5B2D9E42DDD94.

Both options work. I have the feeling that my processor makes less and not so wildly clocked in the option 2. How do I find out which is better for my Systemperformance?

EDIT: Ok I can see the green Glitches. I think I will use Option 3 and wait for the Update Thank you very much!
EDIT2: But with the IGPU I can not use HEVC Codec right?

For your CPU, it's better to use iMac13,2 - it's the closest match.
For proper CPU power management, you need to set the right config parameters (XCPM or SSDT.aml) but that's outside the scope of this thread and you should start a separate thread in the desktop section where others will help.

Yes HEVC will work if your IGPU is enabled but you have to use the Dummy141 kext (to enable h/w encode in AMD GPU).

Sorry my fault! I used the 13.2 xD I will give it a try later. THX

So, i removed shikigva=32, shiki-id=Mac-7BA5B2D9E42DDD94, inject ATI and the FB Name.
Then I activated my IGPU and Configure Clover to Inject Intel and the Headless PlatformID 0x01620007.
I tested the Option 1.
Now my CPU does not have 100% CPU load and clocks properly.
Do I have to pay attention to that?

In VideoProc He shows me my IGPU:
Is this normal?
