1. First, get a USB flash drive with a capacity of 8GB or larger. (Back up the old data in this USB flash drive, because the drive will be formatted during this process).
2. Download the official macOS High Sierra installation package. It is recommended to download it from the App Store. Put the keyword “High Sierra” directly into the search bar in the App Store.
The whole installation package size is about 5GB, so it might take a while to download. It will appear in the “Application” folder as shown below.

4. Open “Applications → Utilities → Terminal”, copy and paste the following command into the Terminal.app:
sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia –volume /Volumes/Sierra –applicationpath /Applications/Install macOS High Sierra.app –nointeraction
Press Enter on your keyboard to execute the command, then you will be prompted to enter the administrator password, it will start the process after the operation:
