I tried to install macOS Monterey and when I do it states application is damaged and can't be used to install Mac OS. What do I need to do?

Check in Applications folder for " Install Monterey " if it exists. If Yes, Drag and Drop to Trash and empty Trash.


Re-download Monterey and preferably using an Ethernet Cable to Router.


Wifi usage may or may not work for a Full Version of Monterey which is about 12.2 GB in size.
