The update gets stuck somewhere before the verifying process and won't continue. Where can I find the update file, maybe delete it, and start all over again? I've cancelled the update and tried to update again, but nothing seems to be downloading.
Have 2013 Mac Pro.
Mac Pro, macOS 11.2
Must first ask - it there any AntiVirus software installed? If so remove as per Developers Instructions. It interferes with the normal operation of the OS. If not applicable - Disregard.
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.

Did you uninstall Sophos? There is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.

Well, you should as it's a superfluous app and is known to compromise system performance as you've already found out. It can also affect Time Machine: Big Sur - "Time Machine couldn't complete… - Apple Community
Read the document I linked to in my last post.
Safe mode worked for my install from 11.2.2 to 11.2.3 on a 2016 MBP.
Not sure if Sophos AV or something else interfered with the setup, but Safe Mode did the trick.
Same here. I also use Sophos. Couldn't get the update to complete until rebooting into safe mode.
No; booting into safe mode prevented Sophos from loading.
macOS Big Sur 11.2.3 update gets stuck and won't update. How to solve?
