Errors with macOS Big Sur Downloading - How to Fix

Apple’s macOS Big Sur is finally available for public download now! However, reports say that macOS Big Sur fails to download on Mac. Some owners get the “Update not found” message while trying to download the update. Don’t worry, here is how to fix errors with macOS Big Sur downloading.

How to Fix macOS Big Sur Download Problems

Update new macOS

There are times when macOS Big Sur update fails to work properly . While some users get the “Installation failed” error message, others have to deal with network error when trying to download macOS Big Sur. Here is the list of other download-related errors users have reported recently:

  • “Installation of macOS could not continue”.
  • “Installation requires downloading important content”.
  • “That content can’t be downloaded at this time. Try again later”.

This is probably because a lot of users are trying to download macOS Big Sur at the same time. So, if you think this is the case, try again later on a non-peak time to see if the download works. Also, you can check the “macOS Software Update” status on Apple Server to make sure everything is alright before downloading.

Additionally, another reason could be the lack of space on your Mac. Make sure you have at least 16GB free for this update. If none of these work, you can open “View My Account” in the App Store to see if there is anything in the “Unfinished Downloads” section and restart the download from there.
