Macbook Air to outfit Sandisk USB with High Sierra via Unibeast 8.3.1.

Boot loader hangs:

vi ~/Library/Logs/UniBeast.log​

Questions

1) Has this problem been solved and documented under different nomenclature elsewhere in another thread?
2) Despite being able to ls the target directory, why are there two errors at t= 21:10:15?

Any insight to overcome the obstacle(s) are greatly appreciated. Thank you

Thanks for the prompt response. I have logged an attempt to follow your instructions, please indicate if I understood it correctly. Steps comprise:

1) reformatting the USB drive
2) rebooting El Capitan macbook

Users-MacBook-Air:~ user$ df -h
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk2s2 15Gi 36Mi 15Gi 1% 9287 3815085 0% /Volumes/Sandisk16

3) rerunning Unibeast:
Users-MacBook-Air:~ user$ df -h
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
dev/disk2s2 15Gi 40Mi 15Gi 1% 10317 3814055 0% /Volumes/Install macOS High Sierra 1

That pesky '1' is amended to /Volumes/Install macOS High Sierra 1 Is this is the cause of the error message?

OS X's file manager (Finder) indicates that the USB is poised to install High-Sierra, however, the device is not bootable. Is there a workaround to make the USB stick bootable?

What are the steps required to make the USB device bootable?

After several cycles of:
  1. Erasing the USB Flash drive with Disk Utility
  2. Applying the Unibeast process
It seems that the Unibeast process remounts the USB device to:

/Volumes/Install macOS High Sierra 1

I am able to list files from:

ls /Volumes/Install\ macOS\ High\ Sierra

If it's mounting it as /Volumes/Install macOS High Sierra 1 it because there is already a /Volumes/Install macOS High Sierra mounted.

@MacMan: Agreed, not sure why '/Volumes/Install macOS High Sierra' is already mounted when booting without USB-flashdrive. I suspect that this is the mounting point that Apple positions the install files for upgrading a Macbook.

QUESTIONS
  1. If I were to amount whatever is mounted to '/Volumes/Install macOS High Sierra', wouldn't that block Unibeast's access to High-Sierra install files?
  2. If not, how can one simply unmount '/Volumes/Install macOS High Sierra'
Perhaps changing /Volumes/Install macOS High Sierra to '/Volumes/Install macOS High SierraTemp' would solve the issue?

I'd like to think that I am following the High-Sierra instructions , however, I am hoping someone will (gently) point out that I haven't and that the obstacles I have bumped into are self-inflicted.

UPDATE

Success! renaming to /Volumes/Install macOS High SierraTemp_temp seemed to solve the problem. It would be terrific I understood how this obstacle was created.


OBSERVATIONS

ls -l /Volumes/
total 8
drwxr-xr-x+ 4 root admin 136 Nov 3 00:45 Install macOS High Sierra
lrwxr-xr-x 1 root admin 1 Nov 21 16:39 Macintosh HD -> /
drwxrwxr-x 7 user staff 306 Nov 21 12:33 Untitled

mount
/dev/disk1 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)
/dev/disk2s2 on /Volumes/Untitled (hfs, local, nodded, nosuid, journaled, noowners)

The last line item is the USB-Flash drive. The Unibeast process remounts it to:

'/Volumes/Install macOS High Sierra 1'
