I wish to perform a clean install of macOS Mojave on my Mid 2013 MacBook Air. I am currently running macOS High Sierra 10.13.6.

I've done all the steps, from downloading the installer from the Mac App Store, to creating a bootable USB using the follow command:

sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled -- /Applications/Install\ macOS\ Mojave.app

Then I rebooted my Mac with the USB flash drive plugged in, holding down the Option key, and got to the select boot media screen.

When I select the USB flash drive to start the installer, I got a black screen with Apple logo and a progress bar. That went well and fill the 100% bar, but then nothing happens.

I've already waited for like 4 hours with nothing happening. enter image description here

I just want to format my Mac to have a fresh start without any junk files.

Can anybody help me with what's going wrong?

    @NimeshNeema would you ask a question on meta if we should flag for redaction of serial numbers? Some people don’t want their images redacted, others do. It would be good to have agreement on this. – bmike Jan 20 at 14:33

    You don't need a bootable installer to do a clean install, but the command to create one should be sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled – user3052786 Jan 20 at 20:31
