cengizhanunal Posted October 9, 2020 Share Posted October 9, 2020 Hi, I've been trying to install Catalina 10.15.7 but it gives an error about ACPI. CPU: i7 10750H Comet Lake GPU: Intel HD Graphics / GTX1650 Chipset: Intel HM470 It is probably about SSDT-EC-USBX.aml but I couldn't get it to work. Thanks for helps. opencore-2020-10-09-165159.txt SSDT-EC-USBX.aml config.plist Quote Link to comment Share on other sites More sharing options...
1Revenger1 Posted October 9, 2020 Share Posted October 9, 2020 (edited) Could be pci or other things to. This link should help: https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/kernel-issues.html#stuck-on-rtc-pci-configuration-begins-previous-shutdown-hpet-hid-legacy When it's stuck specifically at PCI Configuration begin, that usually is either IRQ, PCI Allocation, or RTC. I'd specifically check if you have an enabled AWAC clock first since it's a very recent machine, as that's the most likely thing - then IRQ before PCI Allocation. Edit: Just looked through your config.plist - try adding npci=0x2000 to NVRAM->Boot-args. Looks like you took care of a lot of stuff I talked about above.
