Hi, I have a 2019 MacPro with XDR Display running Catalina 10.15.6. I created both a new volume and a new partition. Downloaded BigSur Beta 3 and launched the installer. Selected the drive (either the partition or volume) In both cases the installation fails after 1 minute with a popup that says: An error occurred installing MacOS. You can try again to complete the installation. Tried multiple time including a fresh reboot. Always fail. I re-downloaded the installer 12Gb but got the same problem. Any hints of something I could try ? Thanks, Guido
