This looks like the right thread for this >
I am not highly skilled with sudo commands, especially not with these complications, but in trying to build a bootable USB device I ran into this error, below. As I understand it, I have a path problem. I took the syntax from Apple's support site, in trying to go from Yosemite to Catalina. There is a footnote on the support page saying to use the --applicationpath argument when building from one of the older versions, and I did that per their example given on the page. but the info from sudo is this:
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:
/Applications/Install macOS Catalina.app/Contents/Resources/../Frameworks/IAESD.framework/Versions/A/IAESD: mmap() error 1 at address=0x103BC7000, size=0x00006000 segment=__TEXT in Segment::map() mapping /Applications/Install macOS Catalina.app/Contents/Resources/../Frameworks/IAESD.framework/Versions/A/IAESD

Can someone please give me a suggestion here? thank you in advance
EDIT: another clue: I have Disk Creator downloaded, but when I run it, select my USB drive, then select the Catalina image downloaded to the Applications folder, it returns this error:
'The selected item does not appear to be a valid macOS Installer.
It is lacking the file "Contents/SharedSupport/InstallESD.dmg" '
but I downloaded from the App Store twice, just to be sure, and that's what it feeds....
should I go to an alternative download location and try again? That app does execute and tries to install Catalina but I want t totally clean install, not carry all this baggage forward.
thx
