You see the error "It seems like something went wrong with the installation of the product" when installing Symantec Endpoint Protection Small Business Edition cloud (SEP SBE) agents on macOS.
We are sorry. It seems like something went wrong with the installation of the product. Please contact Support. [Try Later]
This error can occur if the downloaded zip file or its extracted contents were moved from their original location. The installer error is a result of a new security feature of macOS Sierra 10.12, called "App Translocation".
This should not occur with the latest version of the SEP SBE installer for Mac.
Leave the zip file in the Downloads folder, unzip it, and run the installer from there.
Additionally, App Translocation relies on extended file attributes.
xattr -rc setup.zip
xattr -rc "Install Norton Security"
