High Sierra restored from ISO to USB drive stops at the stop sign I've restored macOS High Sierra ISO file (downloaded from Torrent) to pendrive (16GB SanDisk's Cruzer Dial) using Disk Utility, however when booting from it (by pressing Alt and selecting the drive), it stops on the screen which shows the white stop sign on the gray background.

So I've booted with verbose mode enabled (by holding pressing CMD-V at the start), but the messages aren't clear on what it's failing.

Few messages from scrambled screen are:


  IOUSBHostDevice::message: kUSBHostMessageRemoteWake
  IOUSBHostDevice::forcePowerGated: kPowerStateSuspended completed with 0x00000000 after 15ms




Note: The above black screen is showing booting still in progress.







I don't know how to read these scrambled screens. I've tested on both MacBook Air and Pro and the same thing is happening. The High Sierra was booting before, but not anymore. Restoring the image couple of times (even different High Sierra images) didn't help. It tries to boots to some point, but it stops at the stop sign. The pendrive is brand new and Disk Utility (First Aid) doesn't report any issues with it.

What does the above screens means? How I should correct, proceed or debug this further?
For those trying to create bootable USB from a downloaded ISO file

In my case it was an incorrect way of burning ISO file into USB pen drive/stick using Disk Utility's restore from a downloaded standalone ISO image file. The USb pen wasn't bootable until it was created from files contained inside the ISO using the above command.

STEPS:


Mount downloaded ISO file by double clicking on it (will mount under /Volumes/Install\ macOS\ High\ Sierra)
Run a slightly modified above command and amend source and destination paths if necessary (I used DiskUtility to erase my USB with name set to Untitled and Mac OS Extended (Jurnaled) file type as it failed on APFS file type):

$ sudo /Volumes/Install\ macOS\ High\ Sierra/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled
