Hi all currently installed: 10.15.6, Apple MacBook Pro Late 2018, 32GB Just downloaded the Big Sur Beta 11. When trying to install, it stops with 10 minutes left (tried couple fo times) only with the Error: An error occurred installing macOS. You can try again to complete the installation. Only thing I can find in Console at this point is: Operations failed with error: Error Domain=BOSErrorDomain Code=204 "An error occurred during preflight." UserInfo={NSLocalizedDescription=An error occurred during preflight., UpdateBundleIdentifier=com.apple.bridgeOSCustomer, NSUnderlyingError=0x7fa226e098b0 {Error Domain=BridgeOSSoftwareUpdateError Code=19 "MSU - 37 (FCRT migration failed.);NSPOSIXErrorDomain - 2 (failed to statfs /private/var/hardware);" UserInfo={SystemPartitionSize=1979666432, MSUErrorCode=37, MSUErrorDescription=FCRT migration failed., NSLocalizedDescription=MSU - 37 (FCRT migration failed.);NSPOSIXErrorDomain - 2 (failed to statfs /private/var/hardware);}}} I also tried creating an external media, but booting from this one also fails with an error telling me that the disk needs an upgrade which doesn't work when I click on Update. Network: Had ethernet and Wifi, also tried only with WiFi. same Problem. Any ideas what I can try next? thanks
