Q: How to create a bootable usb for EI captain?
When I was making the boot usb, I found articles with google, yet they are all so obsolete.
many even say using a 8G usb... which obviously is not allowed now, as the minimum requirement is 16G.
I am using the terminal way to make the usb.
what is the most updated process? And what is the sudo code for this please?
i tried the sudo code from some website, it turns out saying there is no 'createinstallmedia' function.
MacBook Pro, OS X El Capitan (10.11.1)

Howdy Guoxuan,
When you mention "createinstallmedia" it sounds like you would like to create a bootable installer for El Capitan.
Note "createinstallmedia" is not a built in function but is part of the installer package as shown in this article.
Create a bootable installer for OS X - Apple Support
Use the 'createinstallmedia' command in Terminal
- Download the OS X installer from the Mac App Store. Quit the installer if it opens automatically after downloading. The installer will be in your Applications folder.
- Mount your USB flash drive or other volume. You could also use a secondary internal partition.
- Open the Terminal app, which is in the Utilities folder of your Applications folder.
- Use the
createinstallmediacommand in Terminal to create the bootable installer. Examples of this command are in the next section. For detailed usage instructions, make sure that the appropriate Install OS X app is in your Applications folder, then enter one of the following paths in Terminal:Path for El Capitan:
/Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia
Note in step 4. the appropriate installer is expected to be in the Applications folder so you can get to it.
The article further gives a more complete example of the command.
The following examples assume that the OS X installer is in your Applications folder and the name of your USB flash drive or other volume is MyVolume:
Example for El Capitan:
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app
If instead you are just trying to create a bootable USB drive, then you would just install El Capitan on that drive as normal, selecting the USB drive as the destination.
Upgrade to OS X El Capitan - Apple Support
Best regards.
