[HALF-SUCCESS] iTunes 12.7 constantly crashing (random messages)

[chiyouhen]

So why can’t we use hardware acceleration and iTunes?

It’s bugging me. Even if I use a native Mac-board id like 18.1 or 16.2 which enables hardware decoding iTunes still crashes...

The hardware does not match the driver perfectly. Apple has never use HD4600 on its products. If we can find a host with HD5000 and the Haswell CPU, and we can set the type to iMac 14,4. I think it would be ok. But it's not easy, because HD5000 is a mobile product for Intel.

I think there must be a way to enable hw acceleration on HD4600 without crash. Take a look about the freezing problem, HD4600 does not support PAVP, IntelGraphicsFixup bypassed the PAVP to make it stable. So there must be a similar way to fix this problem.

And I bought a discrete graphic card. I will test if it is possible to make my hackintosh like a iMac 15,1 or 14,2. And it may enable hw acceleration on the discrete graphic card to prevent crash. I will post my test result as soon as I finish my test.

Do you please like to share your EFI folder (just remove your serials)?

The attachment is a copy of my EFI/CLOVER directory. The serial number and board serial number have been re-generated. Wish this would give you some help.

I have the Envy j-070 which has the Intel 4600 graphics and just tried the latest Shiki build from source and so far iTunes has been stable. I checked VDAChecker and it says Hardware Acceleration is fully enabled. I am using MacBookPro,11,1. Here is the commit: https://github.com/vit9696/Shiki/commit/d28761c617ee7e7ee7728c4c5c1859a85034cf11

I also am using the latest Lilu from source just to be safe.

I have just bought a new graphic card...

It looks like, with this commit, shiki just disabled AppleGVA for iTunes, is it? If so, I don't think this is a good solution. Maybe in another software, the same function call would cause the same crash.

I’m using Skylake HD530 which uses native drivers but it still crashes.

Although only 17.1 iMacs used this processor and not with the HD530.

I found a MacBook which used HD530 maybe I should use that board ID?

be sure that IMEI patched, and 'Trust' checked in clover.

Then I think you can try iMac 16,2 without shiki. No matter what the graphic card is, it is important that if the type has a discrete graphic card. if your hackintosh has a discrete gpu, you should choose the type with a discrete gpu, if not, you should choose the type with IGPU only.

that helped more than the whole other thread I started ...

Blocking iTunes Music HW DRM check should be a temporary fix for iTunes crashing (from Russian post), still need lilu + shiki. Consequence don't know, may be one issue fixed another issue out.

Tested with below configurations, IQSV fully enabled, iTunes Trailers playback work with VDADecoder.
H110M itx/ac + HD510 + AMD HD6450.
B150 Pro Gaming D3 + HD610 = AMD HD6450.

Before blocking HW DRM, AppleSNBFBUserClient and HW IntelAccelerator all enabled.

After HW DRM blocked (replaced with 10.12.6 CoreKE.framework), only AppleSNBFBUserClient enabled, HW IntelAccelerator not activated. Same as ioreg read out from 10.12.6, no more iTunes crashing.

Any chance you can share the kext file that's built from the latest source?

Hi all. Build last version of Shiki from GitHub repository (https://github.com/vit9696/Shiki) and use boot flag "shikigva=16". Its a workaround for iTunes crashes in 10.13.

Thank vit9696 for his work.
