When I select the main disk to install to, I get the error message: "The operation couldn't be completed. (BIErrorDomain error 3.)"
Has anyone else experienced this? I wanted to try out the Big Sur beta, but didn't want to risk rendering my daily MBP unusable.
Thanks!

@paulr9773, I installed from a DMG. Once you have the Big Sur installer, you can create a DMG as follows:
In VMWare, create a new VM and customise, setting the hard drive to at least 60GB. Boot from the install DMG and run disk utility. Select the hard drive and erase as AFPS, then the drive should go from 40GB capacity to 60GB. Then quit disk utility and install.
Code Block cd ~/Downloads/ sudo hdiutil create -o InstallMedia -size 20G -layout SPUD -fs HFS+J -type SPARSE sudo hdiutil attach InstallMedia.sparseimage -noverify -mountpoint /Volumes/install_build sudo /path/to/install.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build # The next step might fail. If so, manually eject using finder. sudo hdiutil detach /Volumes/Install\ macOS\ */ sudo hdiutil convert InstallMedia.sparseimage -format UDZO -o InstallMedia.dmg sudo rm InstallMedia.sparseimage
