ERROR on Terminal doing a Bootable Flash Drive with macOS High Sierra
Good afternoon, @tdunc15 - I hope you are great brother ! I have a new adventure.. I am trying to make a bootable Flash Drive with macOS High Sierra, but there is two issues that it is happening and are the nexts:
a). The computer where I wish to install it supposedly is an unsupported machine (But I’ve have found on internet, that even this it could be installed, by the way).
The specs of my Computer is:
iMac 21.5 Inches. (Late 2009)
System installed: OS X Yosemite ( Version 10.10.5 )
Processor: 3.6 GHz Intel Core Duo
Memory: 4 GB 1067 MHz DDR3
Hard Drive: 500 GB
Graphic Card: NVIDIA GeForce 9400 256 MB
b). ' Through the Terminal ( On my Computer ) I was trying to make the bootable Flash Drive with macOS High Sierra, but the process fails . I don’t know why, because I’ve done all the steps to create it. I have a 8GB Flash Drive [ Already Formatted by Mac OS Extended (Journaled) ]. Also, I’ve Downloaded the Software from the App Store.
The next message Shows Up on the Terminal while I am trying to do it:

Ready to start.
To continue we need to erase the volume at /Volumes/macOS High Sierra (Bootable Drive).
If you wish to continue type (Y) then press return: Y

Couldn't mount dmg /Volumes/Install macOS High Sierra/Install macOS High Sierra.app/Contents/SharedSupport/BaseSystem.dmg (error code 110)Mount of BaseSystem failed.
Additionally, I am showing some images that maybe could help you to identify any information you may ask:
• Format and Capacity of the Flash Drive.
• An image that shows the how looks inside when I open to see the Content on the Flash Drive after the process failed. Also, an image that shows how looks the icon of the Flash Drive on the Desktop.
• Information about the Wifi specs.
Thank you so much in advance !!
