The server gave an error during download: 500 Internal Server Error
I am trying to update a hand-me-down 2014 MacBook Air to Big Sur and keep getting the "The server gave an error during download: 500 Internal Server Error".
I have tried safe mode, restarting, signing out and in of App Store, different times of day, different wifi networks, and nothing seems to work.
I have tried installing an older version of macOS but those also give the same error.
Any ideas are appreciated.
