Boot with USB installer stick stuck at apple logo and progress bar

I want to clean install MacOS Mojave on my retina MacBook Pro (13").

I created a bootable USB stick using createinstallmedia tool from "Install MacOS Mojave.app".

On selecting the usb stick from the boot menu (that appears after pressing option key during boot), the apple logo appears and the progress bar fills up and then it gets stuck. I left it overnight but it was still stuck.

How can I clean install macOS mojave now?

Why not boot into Recovery Mode -- command-r at startup -- use Disk Utility to wipe the disk, and then choose the "Reinstall macOS" option. It will download Mojave from Apple's server and reinstall it for you.

I hope that helps.

Thank you for the response.

I just want to clarify, is 'reinstalling' from the recovery partition same as a 'clean install'. I want to stress that I need to perform a clean install (since I am having some system issues with kernel_task draining the cpu (200-300% usage) ).

That is specifically why I said to erase the disk first with Disk Utility.

Before you do that though, if you are certain that there is no issue with your USB stick, you might want to shut down your Mac and try again with the stick, the reason being that doing it over the Internet will obviously take longer. In either case, I would still erase/reformat the disk first, before running the installer.

Okay that makes sense. Thank you.

Although how large of a download does it require if I do it from Apple's servers?

The internet connection here is not very good and often gets interrupted.

Do you still think it would be a reliable method to erase my disk and try and reinstall from the servers?

Thanks in advance!

The full Mojave installer is just over 6 GB, while the combo updater is 2.06 GB. However, the updater is of no use to you, being as you will be wiping your hard drive first.

Well, if the USB stick is not working, and you don't have the full installer stored on some other medium such as an external backup drive, then you really have no choice in the matter, as far as I can tell.
