    Been having such a hard time installing this new Big Sur 11.3 update. An error keeps popping up “Error… check internet connection” whenever I try to download it through System Preference. And then when I try to download it through the App Store an error of “unable to install due to damaged macOS installer. Redownload installer and try again,” which I did but I still keep getting the same error.
