ltooz_audis 72 Posted November 21, 2020 Share Posted November 21, 2020 The Big Sur is officially out, I downloaded and installed on my HP Elitebook 820 G3 Skylake i7-6600u HD520. The process took a long time to install since it had to boot 3 times and each time took 20 minutes. There are changes that need to be made from Catalina: need to use OpenCore 0.6.4, CtlnaAHCIPort.kext (for SATA to be seen), add boot arg brcmfx-driver = 2 for DW1820a wifi to work, replaced SMCBatteryManager.kext with ACPIBatteryManager.kext for the battery to show up. Cheers, Louis Allan 1 Link to post Share on other sites
