MacOS – Creating a bootable macOS installer errors with ‘dyld: Library not loaded: @executable_path/../Frameworks/IAESD.framework Versions/A/IAESD’

catalinamacosreboot

I'm following How to create a bootable installer for macOS guide by Apple, but it's giving me an error. When I execute

sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/disco

It gives me this:

dyld: Library not loaded: @executable_path/../Frameworks/IAESD.framework/Versions/A/IAESD
  Referenced from: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia
  Reason: no suitable image found.  Did find:

I'm using OS X Yosemite 10.10.5 on a Macbook Pro 2015.

The USB device is a 1TB External Hard Drive, Mac OS Extended formatted.

Encountered this very same issue on my MacBook with Yosemite (10.10.5)

sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

However the very same command on my newer MacBook with Sierra (10.12.6) just runs fine! I suggest building USB install disks from newer macOS if possible.
