Some Mac users say that they can't download programs from other website except Mac App Store, or they may can't be opened the download file. When they click on the download file, it says 'xxx can't be. If you happen to have access to a Mac that's running an older version of macOS, log into the Mac App Store with your password and download the Mojave installer on that Mac. Alternatively ask a. If you can't install the latest macOS, you might be able to install an earlier macOS. Create a bootable installer, then use it to install macOS on your Mac or another Mac. If you just had your Mac logic board replaced during a repair, macOS Recovery might offer only the latest macOS compatible with your Mac. After formatting the drive and starting the install i get a timer stating its going to take -2,393,938,938 and 8 minutes. After about 2mins it pops up saying Can't download the additional components needed to install Mac OS-X. I have tried it with a standard mechanical HDD as well as the SSD.
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.!
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.

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
Can't Download Mac Os X Lion
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.
