High Sierra installer won't run, Can't download important content at this time

[P1LGRIM]

Well I have 10.13.5 Beta on my Macbook now but not find the Beta installer anywhere

You don't have to install any Betas - The guide includes instructions for regular High Sierra too.

Manual not working for me it simply not boot i don't know why as verbose freezes.
Now tried UniBeast 8.10 + Clover upgrade what now booting.

No need for the conspiracy theories - It is just a problem with UniBeast 8.3.1.
Wait for an updated release or use this method :

I don't think its just unibeast 8.3.1. I'm finally getting around to installing macOS with a unibeast 8.2 from March 2nd 2018 and it's giving me the same "Cant download important content at this time" and I don't have access to a Mac to re arrange unibest or redownload and install for a while. If anybody has another method I'm all ears.

This is a known bug in UniBeast and will be fixed shortly in version 8.3.2.

I created a new USB with UniBeast 8.10 from 10.3.4 installer
I updated clover based on https://www.tonymacx86.com/threads/...h-sierra-public-beta-installation-usb.225520/

After reupdated it with the downloadable version from here.

First boot prohibited icon, second booted and now it's installing.

I am here:

STEP 5: Post Installation with MultiBeast
MultiBeast is an all-in-one post-installation tool designed to enable boot from hard drive, and install support for Audio, Network, and Graphics. The installation is complete, but the drive isn't bootable yet. Boot from the USB again, this time choosing Sierra.

1. Turn on the computer
2. Press the hotkey to choose boot device
3. Choose USB
4. At the Boot Screen, choose your new Sierra installation. >>> Here I got prohibited icon again but second boot it continue installation.

Any idea why I can boot only every 2nd try?!

After multibeast it not boot anymore: Error loading kernel cache (0x9)
It boot nice from my USB but not from the hard drive.

Thanks P1LGRIM, this suggestions worked with zero problems, just use non beta commands to make 10.13.4 USB and all Clover Ktexts and settings

My HW:
i7 8700k
ASRock Z370 ITX with TB3
32GB DDR 3200
NVME 960 Pro 1 TB (AFPS, has native Trim Support)
Vega Frontier Edition

Great

BTW : UniBeast is fixed now.

Sorry for the late reply, good to hear that Unibeast for the latest installer should be fixed. I *did* get it working with Unibeast 8.1.0 and the installer from October 2017, that worked surprisingly well.

Now I'm just running into weirdness with getting the drivers right, but I'll start a new thread for that one.

Same results, nothing helps, I wiped and other HDD too, tried to run in my T420 laptop too, same.. :'(

I had the same problem during my installation, use unibeast 8.2 to make the bootable usb
