Mac Os Fails To Download

An installation error occurs sometimes for when upgrading from OS X Snow Leopard to OS X Lion “Can’t download the additional components needed to install Mac OS X” – Check your network configuration as the install needs to pull down software over the internet.

But the network configuration is OK.!

Lightroom 6 fails to download on Mac OS X Sierra scohr. Nov 15, 2016. Hi I'm running OS X Sierra 10.12.1. Purchased lightroom from BH photo and when I get to the download manager, I get a note 'download cannot continue' It doesn't even start downloading (can't even get to 1%).

Check that Software Update can connect directly to Apple Software Update Servers not a custom internal one, remove any Managed Preferences if it is a managed host.

Option 1

If that still doesn’t get rid of the message I have found on a device that the drive needed to be reformatted – the only thing different about the drive I was trying to install to was that it had a Boot Camp partition on it The Boot Camp partition might be a red herring but certainly reformatting the disk solved the issue.

So:

[unordered_list style=”green-dot”]

  • clone the main HD drive to an external disk use CCC – link below
  • boot from the external
  • erase/reformat the main HD – use HFS Extended Journaled
  • clone back the main HD from the external
  • reboot from the main drive
  • run the installation upgrade again

This time – no problems.

If you don’t care whats on the disk just erase it and run the upgrade, I wanted to keep all the data intact in my example, hence the clone back.

Cloning courtesy of the fantastic bombastic CCC.

Option 2

Another potential solution is to remove any RAM over 4GB run the install and then put the additional RAM back in after – even then try and limit the RAM slots to one, so not 2GB in each – rather 1 slot with 4GB.
