Downgrade from MacOS Catalina to Mojave
I've previously downgraded successfully from MacOS Catalina to Mojave on my Mid-2012 MBP Retina machine. Since then, I upgrade back to Catalina. For a different reason, I need to revert back to Mojave. I'm following the same steps that I used previously, but when I go into terminal to create a bootable external drive:
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
I receive this error: sudo: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia: command not found
The Install App is located in my Applications folder, and the name of my external drive is 'MyVolume'. I did notice that when I downloaded the installer it said:
"This copy of 'Install MacOS' application is too old to be opened in this version of MacOS". Is the installer corrupt or something?
