Jerome.Leou Posted November 22, 2020 Share Posted November 22, 2020 Hi guys in this amazing forum, I need help to get rid of fake cpuid for W-2191B in Opencore. Both of my Clover and Opencore can boot normally with fake cpuid 0x0506E4 in Clover and Cpuid1Data E4060500 00000000 00000000 00000000 and Cpuid1Mask FFFFFFFF 00000000 00000000 00000000 in Opencore. However once I delete them, My High Sierra (iMac Pro) can't boot and stuck at 'End Randomseed' for both Clover and Opencore. Based on this thread for getting of fake cpuid , I think at least the fake cpuid is unnecessary in Opencore. I'm really confused that why I need the fake cpuid for Apple natively supported CPU. I attaced my config files, DSDT, and boot log to seek your help. config.plist config_with_cpuid.plist DSDT.dsl opencore-2020-11-21-152132.txt Quote Link to comment Share on other sites More sharing options...
yapan4 Posted November 22, 2020 Share Posted November 22, 2020 You can try this Clover EFI. Just add your personal SMBIOS data and WhateverGreen kext(if needed) yapan4_C422_EFI.zip Quote Link to comment Share on other sites More sharing options...
Jerome.Leou Posted November 22, 2020 Author Share Posted November 22, 2020 Hello @yapan4, I just tried your clover EFI, but my High Sierra was still stuck at 'End Randomseed'. By the way, the clover also have another issue that the clover menu is frozen for mins and will be restored in a few minis. I tried some versions but the issue is the same. This issue just makes me wait mins but it doesn't affect the boot to desktop if you put the fake cpuid in config.plist. Quote Link to comment Share on other sites More sharing options...
yapan4 Posted November 22, 2020 Share Posted November 22, 2020 Here is an old topic about High Sierra Hackintosh on ASUS WS C422Pro/SE https://www.insanelymac.com/forum/topic/333229-help-installing-highsierra-on-xeon-w-2175-and-asus-ws-c422-mobo/ and here https://www.insanelymac.com/forum/topic/335193-help-installing-mojave-on-xeon-w-2175-and-asus-ws-c422-mobo/ newer. Maybe it will help you with your Asrock Motherboard. It's been a long time ago. I have already forgotten everything and do not want to confuse You.
