In Mac OS X Catalina, Apple introduced a Notarization of software requirement. More details can be read here.
Even though the Backup Agent for MAC should install and function properly on build 12.5.14800 , the OS would still produce a warning that the software could not be checked for malware:
"X can't be opened because Apple cannot check it for malicious software.
This software needs to be updated. Contact the developer for more information."
Until the notarization is finalized for the Agent installer and it has a valid Developer ID recognized by the Gatekeeper, please use one of these workarounds:
- Navigate to System -> Security -> Allow for the agent/installation.
- Launch the app you’re trying to run and acknowledge the Gatekeeper warning that prevents the app from running.
- Head to System Preferences -> Security and Privacy -> General and look for a note at the bottom of the screen about an app launch being denied.
- Click Open Anyway to bypass Gatekeeper and launch the app.
