I’d like to help if possible. I’m trying to get mine up and running but it hasn’t been as plug-and-play as others have mentioned.
I think my primary issue might have been with my BIOS — specifically a combo of version number and CFG Lock — since the only way I managed to get my OS (Big Sur) to install was by downgrading to 0714 bios, and enabling
AppleXcpmCfgLock
and
Apple puPmCfgLock
. I also added an
npci=0x2000
boot arg, and lowered my RAM to 4800MHz for good measure.
RAM is working fine at 5600MHz after Big Sur install, so I can’t say for sure if that was a real reason for my KP’s prior to install. Will also try without npci boot arg to rule that out as well.
Note for those with KF CPU’s:
ProvideCpuInfo
is definitely still required. I read (
link) that it wasn’t necessary, but my system would KP without it, unless I disabled the E-Cores.
Also, I experienced the “gray screen” issue despite the
fixes previously provided by
@CaseySJ. The only way I managed to get to the installer screen was through the “old” way: Booting up a pre-installed macOS drive and setting the startup disk in System Preferences.
I haven’t had any success upgrading to Monterey or Ventura — I keep getting an “installer damaged” error.
I’m still in the process of troubleshooting and combing through this thread, but I can post back with my findings.
