“Installation requires downloading important content…” error message preventing me installing macOS Big Sur

My device is a late 2013 Macbook Pro and just a week ago I had been running macOS Big Sur.


I wanted to pass on my device to someone else so I followed the steps in the below links to make sure all of my data was erased and the device is set back to factory settings:


**Installation of macOS could not continue**

Installation requires downloading important content. The content can't be downloaded at this time. Try again later.


I have tried and checked the following:

  • Checked Apple System Status and everything is fine.
  • Restarted the device via Safe Mode and issue still presents itself.
  • Restarted the device and used both CMD+R and CMD+ALT+R modes to install but same issue returns.
  • Erased and formatted the HD to AFPS, reinstalled OS X, same issue. Since then, I've reformatted via the recommended option (Mac OS Extended (Journaled)).
  • I have a good strong connection via Wi-Fi.


Though some of the above may work for others, it hasn't worked for me. I've probably tried erasing my HD and reinstalling OS X about 6 times now.


What can I do?


I don't know where I may have gone wrong, I made sure I followed each step specifically and carefully. I've been able to install macOS Big Sur just a week ago, and now, after following Apple's official guide to essentially 'factory reset' my device, it is not installing.

Users have been reporting issues when people attempt to install Big Sur on 2013-14 MBPros so Apple has disabled Big Sur from installing on these systems. You will need to install an older version of macOS. You can either boot into Internet Recovery Mode using Command + Option + Shift + R to reinstall the original macOS which shipped on your Mac from the factory or you can create a bootable macOS USB installer for any OS from 10.11 to 10.15. You will need to perform a clean install by first erasing the whole physical drive.

Thanks for reaching out to the Apple Support Communities, didarhussain!


It sounds like you are having issues erasing and reinstalling the macOS on your MacBook Pro. You've tried excellent steps so far, and since the issue is still going on, we would recommend reaching out to Apple directly by checking out this link to Get Support and they will be more than happy to proceed with additional steps.


Cheers!
