The Dell OptiMac Big Sur/OpenCore Thread

It's always better to use DP to DP cables instead of any HDMI adapter no matter how expensive or high quality it is. The only adapting of DP to HDMI I've done is to 1080p monitors and that has always worked well.

Alright, then I have to change my Setup a little bit because my main Machine was plugged in to the only DP Port on my Monitor and I think this is also the only Port which supports GSync...

Thanks again for this awesome Guide and all the work you put in there, I really appreciate it. Do you have a Donation-Link?

Btw: What about future MacOS Updates? Can we just Update without Problems or do you test them first and give us Feedback here? I guess it depends on the Update, right? Sorry, its been a while since my last Hackintosh and I always was afraid of Updates...

Can we just Update without Problems

It usually works with no drama. You can of course make a bootable backup before any point update. It's mandatory if you will be doing a version upgrade such as going from 11.6 to 12.0 later this year.

No, not unless you want to run the iGPU headless instead of leaving it enabled.

Sorry but where is here the difference? Leaving the iGPU enabled is, for me, running it headless. Do I understand something wrong? The reason why I'm asking is that I'm also planning to put inside a graphic card (Nvidia NVS 510) for 4k output.

When the iGPU is headless it means you can't connect a display to the onboard DP output on your Dell. The iGPU is then used for compute only. That means the video encode/decode is performed by the iGPU via the Intel Quicksync.
The 14,2 and 15,1 iMacs (and others) operated this way when their CPUs used the iGPU set as headless. The graphics cards powered the iMac display, not the iGPU.

All of this is discussed near the end of the Golden Build guide. Under the "for video editors" spoiler.

upload a copy of your EFI folder, remove the Serials and SMUUID numbers first.
