ltooz_audis Posted December 29, 2020 Share Posted December 29, 2020 I'd built myself a potent PC for Windows and Big Sur to edit videos and play games using i7-6900k 8 cores 16 threads with fully loaded GA-X99-UD5 WIFI motherboard and supported Sapphire Radeon R9-280 3GB graphic card. After a few nights trying to read about x99, trials and errors, I got the Big Sur installation went through the hurdle 13 minutes mark and finished the installation. There are so many threads about this x99 chipset with Haswell E (5xxxk) and Broadwell E (6xxxk) and many kexts that people used, but I found out with the new OpenCore 0.6.4, you don't really need many and the guide here is very close to perfect and this one is for the perfect installation. I believe all x99 chipset motherboards are similar and this would work with any. The most important thing you need to boot initially are these: - SSDT-RTC0-RANGE-HEDT.aml, SSDT-UNC.aml, SSDT-EC-USBX.aml, SSDT-PLUG.aml, SSDT-USBX.aml. After installation, create SSDT-UIAC and SSDT-PRGen for perfect sleep/wake and all USB ports. - Emulate: for Broadwell E Use this from Dortania D4060300000000000000000000000000 instead of nmano F1060400000000000000000000000000 - Follow nmano patch guide to the T. - Remove all patches and things we don't really need. - This motherboard has 2 ethernet ports and they both work perfectly with AppleIntelE1000e.kext. - The Wifi is AC726 so the bluetooth works but the Wifi doesn't although it sees the hardware and mac-address. I'm ordering PCI-e DW1820A for Airdrop support, can't stand having Big Sur without it. - No need to patch DSDT and sleep/wake perfectly. - If I used SMBIOS iMacPro1,1, the video software will freeze while SMBIOS MacPro6,1 will work flawlessly although to get pass compatibility check would fail, need -no_compat_check in the boot-arg. I'll have a video on installation and how perfect this MacPro6,1 performs with Big Sur and Catalina soon. - I attached my config file with serial removed.

ltooz_audis Posted February 15, 2021 Author Share Posted February 15, 2021 I made this video for people who have different x99 motherboards or different CPUs. Cheers, Louis Link to comment Share on other sites More sharing options...
