With the Catalina installer.app in my application folder I'm trying to create a bootable usb disk using this command in the terminal:
sudo /Applications/Install\ macOS\ Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/SanDisk1
the terminal's response: /Applications/Install macOS Catalina.app does not appear to be a valid OS installer application.
After looking around on the web I noticed I'm not the only one with this problem. I've tried another suggested approach by
using a to the desktop copied Catalina.app instead with this command:
sudo /Users/MYNAME/Desktop/Install\ macOS\Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/SanDisk1
terminal's response: sudo: /Users/MYNAME/Desktop/Install macOSCatalina.app/Contents/Resources/createinstallmedia: command not found
yes, i used my real name instead of MYNAME .
I do need to make a clean install since i've been accumulating junk for years and it has to go.
Please help.
Thanks
