slurpi 31 Posted September 28, 2020 Posted September 28, 2020 (edited) Hello everyone: This is just a big THANK YOU! to the OC team. I was able to install successfully macOS Big Sur Beta 6 (version 20A5364e) on my system MSI X299 SLI Plus with Intel i9 9940X using OpenCore 0.6.1. I followed the amazing guide herehttps://dortania.github.io/OpenCore-Install-Guide/ I have been a hackintosh user since 2013, on laptops and desktops. I started with Chameleon but moved to Clover pretty quickly. My X299 system has suffered a lot with the Aptiofix problem, but with OC it was smooth sailing. The guide is really well done! You can read a bit more about my installation here: Basically, I had to add npci=0x2000 to the kernel arguments, and I had to create my own RTC0 patch. Otherwise, all good! Thanks again.
