Upgraded my MacPro 7,1 build to Big Sur today - seamless, and unattended upgrade :headbang: Updated to OpenCore 0.64, introduced the use of "CpuTscSync.kext", replacing "TSCAdjustReset.kext", as well as following "Fixing MacPro7,1 Memory Errors", and removing...

Interesting to read through this thread, and at the risk of being flamed by some, I must ask why persist with Clover, when it has now become a hybridised boot loader dependant on OpenCore to boot Big Sur? Why not take the time to follow the clear and concise guides on OpenCore’s site...

I rebuilt my system a few weeks back, but before doing so I did a DSDT dump and went through the ACPI patching details here, from top to bottom; https://dortania.github.io/Getting-Started-With-ACPI/. For the sake of learning, I created a full set of the necessary patches specific to my system...

I've recently built two new machines with OpenCore (OC6.0 MacPro 7,1 w/ i9-10980XE CPU on MSI X-299-A PRO MB, and OC6.1 iMac 15,1 w/ an old XEON CPU and ASRock z97 MB), and finally converted my "daily drive" (OC6.2 iMac 18.3 w/ i7-7700k on GA-Z270-HD3 MB) across from Clover. In each instance I...

I got my i9-10980XE build up and running the weekend before last. Built on an MSI x299-A-PRO, and 128Gb DDR4 3200 RAM - configured as an iMac Pro 1,1.

@bortoni, are you suggesting that you've native NVRAm support. If so, was it as a result of you updating your Motherboard BIOS?

interestingly, I've been busily shuffling things around on hard disks today, and being asked regularly to approve things like deletions with my Apple Watch - all successfully. Unfortunately still not unlocking, so disabled for now.

Yeah, it does. I even went as far as unpairing my watch and then re-pairing it - all to no avail. :banghead:

So further to @scottkendall , just completed a fresh install of 10.15.2, and the result is SNAFU, no different - exactly as @matksr has stated above.

Seems that 10.15.2 does not resolve this. I recently updated from 10.14.6 (Patch 2) directly to 10.15.1, and it was at this point I lost the ability to unlock with my Apple Watch - post the update I followed The New Beginner's Guide to USB Port Configuration published by @UtterDisbelief...

In moving to an iMac 18.3 system definition, did you simply update the relevant 3-4 keys in the SMBIOS section of your config.plist, leaving your serial number untouched and removed the FakeCPUID setting?

You might want to consider the option I found, thanks to Pike R Alpha, which removed the need to continually update the AppleGraphicsDevicePolicy.kext; https://www.tonymacx86.com/threads/macos-10-12-2-update.209122/page-20#post-1394429

Updated successfully this morning to 12.2.2, and thanks to "fix" from Pike R Alpha, adding "agdp=Mac-00BE6ED71E35EB86" to my boot arguments string, no need to "hack" AppleGraphicsControl.kext" to get past the black screen at boot anymore...

Did you edit the kext directly, if so did you rebuild caches etc? I actually took a copy of the kext first, made the necessary updates and then used "kext utility" (though I am sure KextBeast from TonyMac site will work too) per bilbo123's original post to install the updated kext.

I had this very same problem with my "iMac 12.2" Hack with a nVidia GTX 650 Ti Boost. Details are here; #376, thanks to bilbo123, my Hack is back up and running, just had to add Sierra Desktop/Realtek AppleHDA Audio to this in order repair audio. :headbang:
