Hi Pat, Did you specify that DropDMG **also** sign the dmg file?
In other words, your app is signed and the DMG file is also signed. You can sign the DMG through a DropDMG preference. See “DropDMG -> Preferences -> Configurations”. Look for “Signing”, and enter your Apple Developer credential. - Jeremy > On Apr 24, 2019, at 12:42 PM, Pat Bensky via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > compile the app, sign it … and create a disk image using DropDMG ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
