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

I had just a quite long chat with one of the Apple Advisiours about this problem. After i tried everything he contacted one of Apple Senior Advisors who said that a couple of people reported this issue already the past few hours. He even said that Apple's Techninal team was looking into it and is working on a solution.

So it looks like you can't do anything about it. Because it's probably a problem on their (apple) side what will be fixed quite soon. When i asked of he could give me any approximation when the problem will be fixed he said that it normally will cost s a couple of day to fix problems like this.

I've seen that error several times over the last 2-3 years when trying to install a major update from App Store's "Update" page. If I go to the main or "Featured" page and select the OS update from the small-print list on the right side:

it always installed properly.

This is the link with the correct instructions to reinstall the original OS - FWIW, in order to install a previous or original version, you must erase the hard drive first while in internet recovery.

I got the same problem today after an installation update failed. I did have the latest OS. Got a black screen with a crossed over circle icon "ø "after logging in. Reinstallation of OS required according to Apple support.

Hi, read you can install a previous version. Power off. Start holding shift+alt+cmd+R when starting up. This will allow you to install a previous version. Which version unknown to me. // Good luck, Ulf

My Issue looked to be a problem with my iMAC being in DEP... I removed it from DEP, takes about an hour or so to sync and now it is installing. So not sure if it was DEP issue or if Apple Fixed something but I am working so far now.

Have had a few calls with support on this issue. I was trying to upgrade from a fresh Internet Recovery install of Mountain Lion to High Sierra. After several reinstalls, the rep I spoke to suggested I try downloading El Capitan from my purchased list in the App Store. This solution worked for me, High Sierra is currently installing.

I successfully updated to High Sierra from El Capitan (10.11.6) after this error by:
- going to Finder
- searching for "Install macOS" on "This mac"
- deleting the only result
- going back to App Store
- downloading High Sierra again

Hope this solves your problem too!

It was fine for me 2 days ago but get this in the past 24 hours when try to re-install High Sierra.

how much time will it take to fix this issue?

Everyone here is a user just like you and we do not know how fast or slowly Apple will take care of a particular fix. You may wish to contact Apple support and ask them yourself.

I am getting the same error, I have tried several other steps, I am connected to the internet. Seems like this is an apple issue.

For more information I am getting this error in the logs... NSSoftLinking - The Quartz Framework's library couldn't be loaded from /system/library/frameworks/quartz.framework/versions/a/quartz.

I have the same problem, please I need help

After speaking with 5 Senior Advisors, Dale from Apple says it appears to be an issue with High Sierra servers. No timeline on when it will be back up.
