I am trying to update my Mac (late 2015) to the newest Big Sur update. I started this process at about 12:00 pm (PST) and it is now 2:40 PM (PST). I am hung up on "about 15 minutes remaining" --
Anyone else experiencing this !?
iMac 21.5″, macOS 11.3
If all else fails
Shutdown Router. Shutdown computer and disconnect all External Drives. Restart Router. Connect to Router via Ethernet Cable. If via Wifi - Disconnect all other Devices using the Wifi - want the Maximum Bandwidth only for this computer. Restart computer in Safe Mode. It does a Repair Disk, Clear System Cache files and only load Apple Software, extensions and Fonts. Will load slowly - Normal. Once Logged in - open Apple Apps Store and Get the Full Version of Big Sur. It will take some time and several pauses will occur - normal. Countdown clock may say 15 minutes but in Real time may be 30 minutes. Same goes for clock at 10 minutes could be 20 minutes in Real time. Eventually , Full Installer will download and a New Application in Applications Folder will present called Install Big Sur. Stop there and perform a Time Machine Backup. If desired - have an External Drive - Copy & Paste the Install Big Sur Application to external drive for future usage - making a Bootable Installer. Now run the Installer.
Have found this method more reliable than the Software Update which is very iffy at best
Are there any AntiVirus, Disk Cleaner, Optimizers, Defrag, VPNs etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation.

I'm curious as to what you're supposed to do if you use your Mac for a business in either the EU or UK where GDPR regulations mean it is illegal to store any client data without installed AVS.
Then you install the least invasive A/V software for Macs. From what I've read and heard it's ClamX AV. You might look into that one. I certainly wouldn't want CleanMyMac.
Sorry Sean, I didn't mean to respond to you.
I will do indeed, thanks. It's certainly cheap enough, so I shall have a dig around tomorrow.
Keep us posted on the issue.
I have this problem as well, and the accepted answer of rebooting doesn't solve it. I've tried twice to be sure. Macbook pro, version 11.1, trying to install 11.4.
I've tried numerous times to the point where I just gave up. I'll wait for the next big update and hope that it's not the hassle this one is.
Force shut down doesn’t solve the problem
How do I proceed with the upgrade it does not work ?
Big Sur 11.4 is stuck at "15 minutes remaining" (its been sitting there for 3 hours)
