Can't update DTK to Big Sur 11.0.1

Hi there

I cannot update my DTK from Big Sur Beta 1 it came with to the now released Big Sur from the Mac App Store

I have tried a few ways
  • Software Update

  • - It shows as an update

  • - An error dialog popup shows - Error title: "Download failed" body: "An error occurred while downloading the selected updates. Please check your internet connection and try again."

  • - Note. I have tried to reset defaults in the link in the left which says updates are managed

2 Big Sur Installer
  • - I login to Mac App Store with my Apple Developer ID

  • - I download Big Sur via Mac App Store

  • - Big Sur Installer opens

  • - After running the install for a while

  • - An error dialog popup shows - Error title: "An error occurred preparing the update" body: "Failed to personalize the software update. Please try again"

Also I cannot update Xcode
  • Download and open Xcode 12.1 .dmg file

  • - An error dialog popup shows - Error title: "Loading a plugin-in failed" body: "The pug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled"

Note. I have a Big Sur bootable USB drive but the recovery mode (holding down restart) is different now and I don't see the option to boot from it. I tried to reinstall macOS beta without that USB drive but it fails there too (says something about an internet connection

Is something wrong with my DTK and how do I restore it?
I am having the same problem.

something happens in my DTK that Xcode also doesn't start :(


Hello,
While I could not update to 11.0.1 through Software update, I could manage to do the update through App Store app on "Big Sur".

O.
I also failed to update the DTK either though SW update or downloading the installer manually. But then today I started the DTK machine, and it had updated itself to 11.0.1 automatically. 🤷
