• SIP is fully disabled already. The warning in your screenshot can be ignored.
• Apple's csrutil disable command, however, does not disable all SIP flags. To disable the same flags that csrutil disables, set csr-active-config to 7F000000.
  • More details here.
• However, it is not possible to modify anything in the /System folder in Big Sur.
• We can add files to /Libary/Extensions, but we cannot modify /System in any way.

Thanks, CaseySJ.

I'm trying to add something to /System/Library/Displays/Contents/Resources/Overrides

But without any luck to copy the file I want to replace there I'm going to try what you just suggest and see what happened.

Something is coming soon; probably a couple of weeks to go. Nothing more shall I say...

Cool! Do Let us know !

Again, we cannot modify the /System folder in any way. But we can add a DisplayEDID-x-x.kext into /Library/Extensions (and rebuild kernel cache by typing sudo touch /Library/Extensions then rebooting) or into EFI/OC/Kexts (and add reference in config.plist --> Kernel).

Override files can go into /Library/Displays/Contents/Resources/Overrides instead. That's where SwitchResX puts them. Are you trying to do a mtdd or icns file instead of an override file?

Hi

I tried 4 times to update to Big Sur 11.4 (Opencore 0.6.9).

Every time I have one crash during the upgrade, but then installation continues.
After installation it will crash and reboot after every login.

I was trying to update from Big Sur 11.3.1 on my Z490 Vision D which was rock steady.

Anyone had this issue ?

HI all,

I know that the recommendations when it comes to BIOS is to stick to F5. Is anybody running their config with F20? The reason I am asking is that, when booting my system with my 6800XT, I have no video until macOS is loaded. I mentioned recently that I fixed it by running 2 PCIe power cables to the video card rather than one with a splitter, and also unplugging/plugging the monitor but it worked only once. I tried to reboot the system so that I could boot Windows 10 but same problem reappeared. Reading several posts in the net, a few people fixed the issue by flashing the BIOS to the latest version (not necessary on a Z490). Just curious to see if people on this forum are running the Z490 with the latest BIOS which is F20. Thanks.

My setup does not go to sleep at all. Have you guys ever faced with this problem?

I do, everything works perfectly

f20 is working now. Also, with f20, if you enable VT-d, you get kernel DMA protection for Thunderbolt in Windows, if you care about such things.
