macOS Big Sur download error

Hi.

I recently opted out of the macOS Beta Program, and have now received the 11.3.1 update. However, the update always downloads to 486.0 MB, and then freezes, sometimes cancelling and blaming a network issue as the problem, despite the internet connection working completely fine.

Is there any way to fix this?

MacBook Air 13″, macOS 11.3

A couple of things spring to mind. Is the Internet Connect behind a VPN ? If so, reconnect without the VPN. Secondly, any Antivirus Software installed and running ? If so, Remove as per Developers Instructions.


Further, try doing the 11.3.1 from Safe Mode.
