Delete MacOs Catalina File
I recently upgraded to macOS Big Sur but then changed my mind due to some important apps not working with the new software so I downloaded the macOS Catalina installer from the app store but then the installation failed so I decided to wait for the apps to work instead of downgrading but the problem was that i cant delete this installer file (8GB) and its persistent. These are the errors that popped up. Please Help
