Apple Intelligence is now available on iPhone, iPad, and Mac!
macOS is failing to update Big Sur. I'm trying to do it to 11.2.3, but I guess it's never worked since I got this new M1 MacBook Pro since I'm still on 11.2 (20D64)
If I try to install via Software Update I get this error, even though my internet connection absolutely fine (fast, stable etc):
If I try to update using the App Store, (the big 12GB one) I get a different error message:
Any ideas on how to solve this?

See if either works while in Safe Mode.

Suggest - restart Router and then Shutdown Computer and connect via Ethernet connection. Restart computer in Safe Mode - Shift - Key immediately at startup. It does a Repair Disk, clears cache files and load only Apple Software - load slowly - Normal. Once in Open Apple Apps Store and find Big Sur and download. Try not to let computer go to sleep mode or Screen Save to activate. Be patient as one knows it Big Sur is 12.18 GB size. There are often periods where it seems to pause the download , normal be patient as countdown clock may say 15 minutes but in Real Time could be 30 - 45 minutes. This can and will happen several time in the process. If all goes well. it will successfully download and attempt to Launch. Do NOT allow it to start - Quit the Installer. Check Applications Folder for new App called Install Bug Sur. Make a copy to External Drive - future usage. Now, restart again in Safe Mode - then launch the Installer.
Thank you both. Safe mode + the big installer did the trick. Much appreciated.
You're welcome.
