macOS 11.0.1 has been released to the general public a couple of days ago, but the roll-out has been plagued with problems. Users haven’t been able to download macOS Big Sur for several hours, because Apple’s servers failed to handle the load of worldwide Mac owners trying to get the big release.
‘An error occurred while installing the selected updates’ was displays on the majority of Mac screens, as soon as the users were clicking the Upgrade Now button. This was generated by Apple’s servers being unable to process a the huge number of update requests.
Situation has improved since but we’re still receiving reports from users that complain about the fact, that although the macOS Big Sur download is ongoing, the estimation times are hilarious, with Macs predicting thousands of days of remaining download time!

Tips To Fix macOS Big Sur Download Stuck
Depending on the situation you’re in, you can apply these tricks to successfully download macOS Big Sur on your Macbook:
1. Time Your Update
As medicine says, the best heal is prevention. To avoid that you don’t get a Downloading macOS Big Sur… dialog box that reads thousands of days remaining, plan your update at odd hours. This means a time of day (or night) when most people won’t update. I found that Apple’s server are least overloaded very early in the morning 5 – 7am (your local time).
2. Internet Connectivity
Secondly, make sure that your Wi-Fi connection is strong and stable. Wi-Fi hotspots can get overloaded too, especially if other users your house or workplace are also performing bandwidth consuming tasks.
More: You could be the only one on your hotspot, but if the connection is intermittent the remaining time might dramatically increase, when the Internet connection is idle. However, in this cases the estimation should return to normal values when the connection is re-established. That’s if this problem doesn’t overlap with busy Apple Server, and your macOS Big Sur update might get stuck or occur very slow.
3. Restart The Procedure
If still reach to be prompted by macOS Big Sur download estimations of tens of years, don’t panic. Be a little patient and wait it out to see if the download speed recovers. If there’s no breakthrough, proceed as follows:
- Stop the download, using the ‘x’ icon available at the end of the progress bar.
- Open the Finder app and search for the ‘Install macOS Big Sur‘ file.
- Right-click on it and Delete it.
- Empty Trash and Restart your Mac.
- When ideal conditions are met, Open System Preferences (Dock), click on Software Update and restart the macOS Big Sur download!
