surenmunoo Posted May 24, 2021 Share Posted May 24, 2021 Hi All, I have an Asus Z370-P which boots Win 10, Catalina and Big Sur. In BS I do not have HEVC working but it works perfectly in Catalina and Win 10. I fly my drone quite often and record videos in H265 4K and I cannot watch those in Big Sur but only in Catalina. I am using 1 Open Core 0.6.9 EFI to boot both BS and Catalina. Can anyone help to explain how this does not work in BS. I am also using iMac 20.2 SMBIOS and even tried 19.1 but still the same in BS. Also in Catalina Airplay works and sees my Samsung TV but in BS it does not work. Quote Link to comment Share on other sites More sharing options...
