Unable to install the MacOS Big Sur upgrade
I have a 2019 MacBook Pro [with Catalina]. Each time I attempt to install the Big Sur upgrade I receive this msg "An error occurred installing macOS. [and] You can try again to complete the installation." I have tried to install at least 30 times, and using a variety of methods [Safe Mode, Recovery, from different sites, and with a new Admin user]. It's always the same. Has anyone experienced the same?
MacBook Pro 13″, macOS 10.15
