YoMuS Posted November 24, 2020 Share Posted November 24, 2020 Hello everybody, I've been trying to install Big Sur in my brand new desktop (i5-10400, Asus h470, igpu) following to the letter the dortania guide for this platform with no luck. I always get stuck at this point. It appears to be a CPU related. IoPlatformPanicAction -> AppleSMC and the Fault CPU is the only thing I can get anything to work with. I'm using iMac20,1 as advised, and chose the BIOS settings suggested in the guide (except for Execute Disable Bit, which is not present as an option). Anyone has a clue? Thanks in advance!

YoMuS Posted November 25, 2020 Author Share Posted November 25, 2020 Never mind. After manually creating the ssdt files according to my specs, I'm past this kernel panic. Now I have another, related to USB .. Link to comment Share on other sites More sharing options...

I'm using iMac20,1 platform and Catalina works great... but I can't get to the installation screen at all. Thanks! Link to comment Share on other sites More sharing options...
myradon Posted March 19, 2021 Share Posted March 19, 2021 (edited) I've exactly the same problem! Somehow my Hackintosh throws a kernel panic while booting Big Sur USB Installer. I've tried other USB-stick, Working EFI from OC (0.6.2) Catalina Installer to Big sur installer. Same fail. I've swapped failing OC EFI-folder (OC 0.6.7) and put on to Catalina Installer.; no problems. It boots. I've ditched all custom SSDT's and used files for Comet Lake on Dortania guide along with USBInject.kext. Still same problem.I've played with config.plist settings. Still no luck. Debug kexts traceback to VirtualSMC. I believe a dev over here explains tracebacks to VirtualSMC is most likely not VirtualSMC itself. So now stuck. What the heck is wrong?

Well maybe you're in luck, because I finally discovered what the problem was. One of my USB devices (bluetooth dongle), was causing the kernel panic. As long as I booted the system without it, the installer goes through without any issues. Try disconnecting every non-essential device. Bye!

Try disconnecting every non-essential device. Bye! I can't believe it! You're 100% right. I removed several USB-devices.. no luck. I was "okay last resort. Let's unplug genuine Apple USB Bluetooth device" which I soldered on internal USB-header. Boom installer.....WTF! Would apple have dropped support? But would it throw a KP? Odd!
