Does anyone know how to make a bootable GM flashdrive ?

Simple question. Using DiskmakerX not longer work using the yosemite trick. You can create a bootable flash drive which stuck during booting in the loading bar... never gets to the welcome screen.

AFAIK, Apple's official documentation still works for 10.11: https://support.apple.com/en-us/HT201372

1. Download El Capitan from the app store.

2. Plug a properly formatted usb Drive with 8GB to the computer, name the drive Untitled, this is important for the next step to work.

3. Start the terminal app and paste the next command:

sudo /Applications/Install\ OS\ X\ El\ Capitan\ GM\ Candidate.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan\ GM\ Candidate.app --nointeraction

4. Enter your password and wait until the files are transferred to the usb.

5. That's it. Restart the computer and press the option key and follow the instructions on the screen.

6. During the installation, almost at the end it seems like something is wrong... because it seems like nothing is happening, just wait... the laptop is doing it's thing.

Disk maker X worked great, made a USB-C and regular USB 3 Bootable drive last night.
