Recently my sister asked me to reinstall the macOS High Sierra on her iMac because it stopped working correctly. I thought that it would be easy to do but I was mistaken. I successfully installed the macOS Mountain Lion (when using the NetBoot it automatically selects the version of macOS with which the iMac was shipped with). But then I was facing multiple issues trying to update macOS from Mountain Lion to High Sierra via the Mac App Store.

After downloading a copy of macOS High Sierra from the Mac App Store, I started installing the update. The Mac rebooted, and it seemed that everything was going well, but it was not. The progress bar did not move at all, or moved very slowly. I waited a few hours…

And then click on “Erase” to erase and format the external disk or Flash drive.Formatting an External Disk or a Flash Drive for Mac.

I began to figure out what was going on and found out the following. Attempting to download macOS High Sierra from the Mac App Store I found that a small 19 MB version of the “Install macOS High Sierra.app” file downloads to the “Applications” folder, rather than the complete 5.2 GB installer file. That’s the problem.

The tiny 19 MB incomplete installer requires an internet connection during usage to download the rest of the High Sierra update files. Additionally, it does not allow me to create a macOS High Sierra USB installer drive for use on multiple computers.

I’ve found a new workaround, and in this tutorial, I’ll show you how to download the complete “Install macOS High Sierra.app” file from Apple server using the “macOS High Sierra Patcher” app instead of via the Mac App Store.

About the app

In this workaround, we’re going to use the macOS High Sierra Patcher app from the dosdude1.com. This app is intended for those with unsupported Macs and Hackintosh users, but any Mac user can use the app to be able to download the complete macOS Mojave installer file from Apple server. For our purposes in this particular walkthrough, we will use the app only to download the complete installer file.

Note! This method relies on a third party app from an unverified third party source. If you are not comfortable with using unvetted and unverified software, do not follow this process.

Let’s begin

Hold down the Control key and click the app icon. From the contextual menu choose Open.
A popup will appear asking you to confirm this action. Click the Open button.
