Hi,

I am facing issue of the clear install of mac os sierra using USB , It is throwing me an error while making the device bootable

I Have used 32GB Pendrive

the final error was

Sharat-Kumar-Reddy-Gs-MacBook-Pro:~ sharatkumarreddyg$ sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ Sierra.app

Ready to start.

To continue we need to erase the disk at /Volumes/Untitled.

If you wish to continue type (Y) then press return: y

Hi ,

It din't work.

The disk could not be created because of an error: An error occured: -10006. Finder got an error: Can’t set disk "Install macOS Sierra" to "DMX_Workdisk".

The above error was shown

Try deleting the existing Sierra install and redownload. 

I suspect the existing one is corrupted.

Yep tried again same error again .

Try another drive

I just ran into the same issue and was able to fix it. The problem was that the partition "Scheme" for my flash drive was "Master Boot Record" which is an ancient partition scheme used by Windows. Macs cannot boot from drives with such a partition scheme. Erase your flash drive and pick any of the other two schemes (I did GUID which does not match screenshot below).

After that, createinstallmedia succeeded. I have yet to use the USB drive but I assume it will work fine.

One would hope createinstallmedia would perform the check before wasting several minutes and give you a helpful error message.
