@gabevf - No, I tried various guides on here about iTunes DRM and never had any joy. After several days of frustration, and out of sheer curiosity, tried an OC Catalina build with an 5700xt and it worked OOB with TV app. But for my use case, I really needed to sitck with high Sierra, and sadly...

Hey everyone! I was wondering if anyone knew if VDA decoding was possible with opencore on X299 high Sierra with GTX 1080. Thank you!

Moderator- should this be moved to x299 opencore support? Thank you

Hello All! I'm having a bear of a time with opencore trying to actually enable hardware acceleration and DRM support. I know it is most likely a configuration issue(was working with clover bootloader), and I was wondering if someone who had a similar system wouldn't mind taking a look and seeing...

Update 8.24.17- so last night gigabyte came out with a new bios, f23b. It's supposed to fix hyperthreading errors. After my last post, there was a few weeks of great operation and a few weeks of terrible crashes, back to the initial problem of instant reboots under video encoding load. After...

Did you ever solve this?

Ok, thanks for taking a look! Oddly, without the one that injects into XHCI, the system panics. Without the one that increases to AppleUSBHCI , rear USB 3 Ports don't work. Every time I think Im close, theres another panic. Do you do any video work? The problem I'm trying to fix only happens on...

Cool, got it thanks. Are you using the x86PlatformPluginInjector? I don't see where your loading it - Would you mind taking a look at mine and seeing if there is anything out of place that might be blocking it, since we have the same hardware? I noticed you were using some CustomUUID strings...

Thank you, but I don't see the attachment!

Ok- thanks! I've been chasing a kernel panic around my machine for months, now, every little bit helps!

Yeah, that has been my experience - how do I re-extract and repatch using clover? Im having a lot of trouble getting the x86PlatformPluginInjector to stick and maybe this is why.

I have basically the same hardware, and the bios time is different on my mobo bios as well. Can you post a guide to exactly the steps you took to correct the problem?

Ok update on this post - Problem 1 Ethernet was killing my network SOLVED - that turned out to be a check box in AirPort Extreme (I disabled IPv6 sharing, and Viola!) both ethernet ports work like a charm[as they have] but the rest of my network stays online! (I feel pretty silly about this one)...

Alright! You fixed it! The problem was that I had installed the file to S/L/E with 0x67. Moved x86Platform... to L/E with 0x67 and panic fixed. Now CPU stepping is good, Geekbench is much improved, and video renders without crash!! Now if I can get the ethernet and USB SSDT sorted out, I will...

is there any chance that changing my CsrActiveConfig to 0x67is throwing the panic?

That has to be what I did wrong! When I look in the kext package contents for the plist, there is two - an info.plist and a Mac-65CE76090165799A.plist - should I delete one of them? They both have different info. Im sorry to keep bothering you, I am just now throughly confused. Thank you again...

I think I found the problem with the panic - while booting with the latest platform inject kext I got from you, There is a panic - was I supposed to rename the plist within that kext the iMac 17,1 system definition as well?

Well, I think I broke it - I have no idea how to get back in! Using a backup config didn't work, and neither did blocking the x86PlatformPluginInjector

Shuhung, ok thanks for adding that file. How did I do? My power gadget doesn't look anything like yours. but the temperature is low and the overall power consumption isn't bad. Did I put the tiny PM in the wrong spot? Would you happen to have any insight into my USB configuration problem? Thank...

Shuhung, thank you for the suggestion! Do you know where I can find the X86PlatformPluginInjector and a guide to implement? I am feeling like all of this is getting over my head quickly, and I don't want to break the machine any further!
