Without it what CPU does it show in About This Mac? Doesn't it show the correct CPU already?
Yes, it does. The correct CPU in both cases. My assumption is something wrong with the latest OC changes, especially in the try to adopt Alder Lake CPUs. But anyway, I'm worrying if anything uncurrent in my other properties. Could you please enable that property and let me know if your system boots?
I think you may misunderstand the need for the quirk, its not required for the Z390 chipset and 8th generation processors. It was added in 7.0 and helped with some VM setups (if I understand correctly) AMD processors being incorrectly identified and now for Alder Lake. I don't have it enabled and if it causes system problems as you describe neither should you.
I'm not sure if the following investigation depends on that property, but I couldn't run 'Bootcamp Windows' from the macOS in Parallels Desktop until I set that property as 'true'. Otherwise, the Windows inside the Parallels showed me the blue screen during the boot ('INACCESSIBLE_BOOT_DEVICE' error).
You are probably going to need to look elsewhere for support in running Parallels on a Hackintosh, I can see how it would be problematic. If it worked before in 7.6 then I would look closely at all of your previous settings in the config.plist and make sure they are the same. It is possible the new version of OC 7.7 itself is the issue, if so and if its that important to you, I would roll back to 7.6. There aren't enough fundamental changes to the two versions of OpenCore to make a difference on your machine whether it is an 8th or 9th generation CPU. They are both Coffee Lake CPUs and use the same chipset.
Thank you for the reply! I will think about downgrading. It is not a good practice in my opinion. The older version is installed, the more difficult it will be to upgrade to the new one after the time.
Your choice as to how you want to proceed but if you need Parallels working soon then its your best option and no, its not harder to skip multiple versions and then upgrade. It may seem like it but that's another issue.
