Hi @CaseySJ,
about DRM issue on Big Sur (now on 11.1), the only way for me to have Netflix and AppleTV+ working is to switch from iMac19,1 to iMacPro1,1 (with IGPU still enabled by Headless). Opencore is on 0.6.4.

Have you same issue on iMac19,1 ?
Hello @Elias64Fr,

Salutations de la saison!

Yes, we have found the same result. System product names such as iMacPro1,1 (without iGPU) are able to play DRM content from the TV app.

Regarding Netflix, however:
  • Will not play in Safari (with iMac19,1)
  • It will play fine in Firefox (with iMac19,1)

BIOS configuration is the same in Mojave, Catalina and Big Sur. Please see Post #1. However, ensure you have BIOS F9g or newer and also set Boot --> CFG-Lock to Disabled.

All updated. Still nothing. Must be the PCI Card. It could be that it broke before the update. I hadn't used it for a couple of weeks. The slots are working so it must be card itself. Thank you for your help, though!

Concerning Hot Swap. I noticed the fix is already in the template you guys made. Unfortunately it doesn’t work on my end :(
Just to confirm:
  • You enabled the Kernel patch shown below?
  • Then rebooted, but SATA hot swap does not work?

@CaseySJ Salutation !

OK thanks, I still have IGPU enabled with Headless. VideoProc HW decoder show me UHD 630 but no IGPU load on Intel Power gadget during test.

I am still using PCIe cards that are almost a decade old. It's quite rare for them to go bad suddenly, but not impossible. Does the PCI card work under Windows or Linux?

That makes sense with iMacPro1,1. Because Xeon processors do not have iGPU, iMacPro1,1 should avoid iGPU system calls.

This makes me wonder - in the most recent OC template, how is the iGPU configured? It's doesn't show up in any specs so I am guessing it's either in headless mode or disabled?

The iGPU configuration has not changed. It's set up as follows:
  • config-AMD-GPU.plist --> Platform ID 0x3E980003 (headless)
  • config-Intel-iGPU.plist --> Platform ID 0x3E9B0007 (non-headless)
In both cases, iGPU will appear in IORegistryExplorer under iGPU@2 on the left side.
