Certainly -- both iMacPro1,1 and iMac18,3 can be used with the OC 0.7.2 EFI.Is it possible to do a clean OS install using OC 0.7.2 on a Z490 Vision D i9 10900K? Using a config setup to iMacPro1,1 , or iMac 18,3.
Ahh I see. I’m using iMac20,2 on Big Sur.No, not iMacPro1,1.
That was my point.
You may need to experiment (while disconnected from the Internet to avoid Apple getting suspicious) because the Terminal command does not necessarily affect QuickTime directly. I'm running Mojave and iMac18,3. Many will tell me this is wrong. I disagree, everything works well and reliably. However it is possible that special use cases, such as yours, may need a different definition.
I am using only the one Terminal command you highlight, yes. This is purely because the official Whatevergreen guidance suggests this is all that is needed - and it is for me.

No apologies necessary More info is always better than less info, and now we have evidence that the DRM issue in Big Sur is SMBIOS agnostic (iMacPro1,1 aside)@canyondust and @CaseySJ
Hello again. I thought I'd do some more testing here ...
Okay I have to apologise.
I swapped over from Mojave 10.14.6 to Big Sur 11.5.1.
Sadly you are correct @canyondust. I used the Terminal command to enable DRM playback and sure enough QuickTime would not save the screen recording. It would seem to record okay but gave an error when Saving:

However when I set the Terminal boolean command to "no" then everything recorded as it should:

Which is really annoying. My previous post is still valid for Mojave, but ...
Hands-up, I was wrong. Clearly Big Sur causes another new issue, so not much use here.
Apologies again to both of you for cluttering the thread!
If you change the SMBIOS to another mac, can you keep the same serial number? I have been trying to find a serial that works, but it says incorrect.Certainly -- both iMacPro1,1 and iMac18,3 can be used with the OC 0.7.2 EFI.
