With the release of El Capitan, the script to create a Bootable ISO for VMware of Mavericks and Yosemite does not seem to work anymore on the El Capitan official release.

The ISO simply does not boot.

Below is what I found that worked. Since I've been looking for this for a couple of days, I figured I'd share it. - Enjoy!

 #!/bin/bash

 # Mount the installer image
 hdiutil attach /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

 # Create the ElCapitan Blank ISO Image of 7316mb with a Single Partition - Apple Partition Map
 hdiutil create -o /tmp/ElCapitan.cdr -size 7316m -layout SPUD -fs HFS+J

 # Mount the ElCapitan Blank ISO Image
 hdiutil attach /tmp/ElCapitan.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build

 # Restore the Base System into the ElCapitan Blank ISO Image
 asr restore -source /Volumes/install_app/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase

 # Remove Package link and replace with actual files
 rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages

 cp -rp /Volumes/install_app/Packages /Volumes/OS\ X\ Base\ System/System/Installation/

 # Copy El Capitan installer dependencies
 cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System/BaseSystem.chunklist
 cp -rp /Volumes/install_app/BaseSystem.dmg /Volumes/OS\ X\ Base\ System/BaseSystem.dmg

 # Unmount the installer image
 hdiutil detach /Volumes/install_app

 # Unmount the ElCapitan ISO Image
 hdiutil detach /Volumes/OS\ X\ Base\ System/

 # Convert the ElCapitan ISO Image to ISO/CD master (Optional)
 hdiutil convert /tmp/ElCapitan.cdr.dmg -format UDTO -o /tmp/ElCapitan.iso

 # Rename the ElCapitan ISO Image and move it to the desktop
 mv /tmp/ElCapitan.iso.cdr ~/Desktop/ElCapitan.iso
