[QUOTE="sonb, post: 1867758, member: 406222"] Hi there. I tried creating a bootable usb big sur installer but i keep getting an error at the end. Not sure if the installer is causing the issue or my mac hardware. I downloaded Big Sur installer at apple store on 3 separate occassions, all 3 installers have the same result when creating a bootable usb. As you know there were issues on the upgrade/update since the Big Sur rollout 2 days ago. I am using a mac pro 2017 model with latest catalina update. Look forward for some help.
