Carlosan 2,466 Report post Posted April 25, 2020 Hello Hope this help 3DC for macOS has been signed and notarized with Apple. Ensure to check "System Preferences > Security & Privacy > General > click the "lock" > select "App Store and identified developers". When only the "App Store" is selected an error message is displayed "3DC.xx.dmg" can't be opened because it was not downloaded from the App Store. Your security preferences allow installation of only apps from the App Store. If not please ask for support at support.linux@3dcoat.com Thx Share this post Link to post Share on other sites
