Creating a Bootable Catalina installer
I'm running Sierra 10.12.6 with the Install Catalina.app in my application folder and with a SanDisk usb stick formatted to Mac OS Extended (journaled).
Terminal command:
sudo /Applications/Install\ macOS\ Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/SanDisk1
Terminal response:
/Applications/Install macOS Catalina.app does not appear to be a valid OS installer application.
Following a suggestion (permission issue?) found on the web I also tried this:
I copied the Catalina installer to my desktop and used this Terminal command:
sudo /Users/MYNAME/Desktop/Install\ macOS\Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/SanDisk1
Terminals response:
sudo: /Users/MYNAME/Desktop/Install macOS Install: command not found
yes, i used my real name instead of MYNAME.
I'm totally frustrated. Again.
Any help is highly appreciated.
THANKS!
