Yes, I ran into that this weekend. Try moving the installer to your desktop and right clicking then selecting open. It eventually gave me an option to continue.Mac OS Catalina will not let me install the Map update Portal. Is says “Map Downloader Installer” can’t be opened because Apple cannot check it for malicious software.This software needs to be updated. Contact the developer for more information. Anyone else have this problem?
Which are different from the MY Subaru website.
