Error installing macOS Big Sur

I downloaded the installation profile for macOS Big Sur beta from my apple developer account. It downloads a DMG.

When I try to open the DMG I receive an error: "macOSDeveloperBetaAccessUtility.dmg" is damaged and can't be opened. You should move it to the Trash.

I checked my partition for errors, to no avail.

Does anybody know how to fix this, so I can install the beta access utility. Alternatively: is there a way to install Big Sur directly, i.e. without installing the beta access utility first?




First thing to try would be delete it and download it again. There might have been a glitch when you downloaded it the first time.
