The solution is a lot easier, than anything that I have read on this forum.
Just turn your system clock back to the 2015 time frame during the install, then, turn it back to
current, when you're done. POC

How did you. Mine would not even fire up App Store with the wrong date.

A real solution for those who get stuck at STEP 1.

Seeing no real solutions offered here on the forums, other then seeing users getting pushed to look at the troubleshooting guide for UniBeast 8 and then coming back empty handed because they are stuck at:



The troubleshooting guide won't supply users with a fix and users getting all over forums pushed back to the guide.

The fine install guide tells you in step 1:



And then you windup with an installer thats 19MB in /Applications.

Then you start UniBeast and it says "Selected Mac OS X Installer is incomplete".

If this is you then you can fix this by doing the following:

You will need to recreate the full installer from the separate parts.

To do so we will use the installer stub app to grab all the files from Apple and then abort the install before it does anything else.

Run the 19MB stub installer (/Applications/Install macOS High Sierra).

Choose the install disk and click ‘install’ (it won’t actually install yet!).

It will download the remaining install files and place them under /macOS Install Data (i.e. look for the folder in the root of your hard drive ‘Macintosh HD’).

When it has finished downloading all it needs, the installer screen will then ask you to restart the Mac – but don’t! At this point ABORT the install by quitting the installer app.

Next we will recreate the full installer from all the downloaded parts. This will restore the ability to create an install media USB.

Do the following:

Open Terminal and run: sudo -s
Enter admin credentials to gain root permissions.
Then copy and paste the following 3 commands:

mkdir /Applications/Install\ macOS\ High\ Sierra.app/Contents/SharedSupport

cd /macOS\ Install\ Data

find . -mount | cpio -pvdm /Applications/Install\ macOS\ High\ Sierra.app/Contents/SharedSupport


You now have a full installer package in your Applications folder!

Now goto STEP 2: Create a Bootable USB Drive with UniBeast to continue the install guide.
You're the best dude thank you so much

The op's solution may work for some, but if you experienced a LONG extraction process after running "find . -mount | cpio -pvdm /Applications/Install\ macOS\ High\ Sierra.app/Contents/SharedSupport" then you need to just simply COPY that folder from the recently downloaded location (in folder "macOS Install Data") TO the /Applications/Install.../Content/SharedSupport/ location. Blow away any other files in that SharedSupport folder first. Then do a copy so both folders are exact duplicates. That's what I had to do.

Excellent guide.

There is something I want to mention. In this support document : https://support.apple.com/kb/HT201372

It is mentioned under "Download macOS from the App Store" that :


So if we attempt to download MacOS High Sierra from a Mac or hackintosh that is not running El Capitan 10.11.6 / Sierra 10.12.5 or 10.12.6 / High Sierra, then all we get will be the 19MB file. Like I tried on my Mac mini 2012 Server running Mavericks. I tried repeatedly and could only get the small file and not the full installer. Now I understand why.
but I have high seirra and I got the 19mb download

I did too. All you must do is to begin installing to any macOS hard drive. Dont worry it wont actually do anything. It just takes maybe 30 minutes or so to download. It says installing but it's really not. At the next step just hit cancel or quit installer. Then you will find in Computer / (HDD NAME) / a folder called macOS Install Data. Open this folder to reveal the full 5.1 GB download. Then copy it to the folder within the app. Do this by right clicking on the install macOS High Sierra app. Click Show Contents. Within the contents folder there should be a folder called SharedSupport. If not create it. Now dump contents into there. Now Unibeast works.
