All macOS installers are now "notarized" by Apple to enable automated installation in macOS 10.15 Catalina.
In order to support notarization, the minimum supported macOS version is now 10.9 Mavericks and the minimum supported FileMaker version is now 14.
All UI elements updated to support macOS "Dark Mode". This made some rarely-seen Dark Mode dialogs in the installer more readable and will also support future FileMaker versions that run in Dark Mode.
