FREEDOME installation displays a message about an unidentified
developer with macOS Catalina developer beta
The forthcoming macOS 10.15 Catalina has been released as a developer beta version to the Apple beta testers and developers. It has a new feature which checks that the applications are from notarized, identified developers when they're installed. If the developer can't be identified, a warning message about an unidentified developer will be displayed to the user. This feature is still under development and may not always work as expected.
If you try to install the current version of FREEDOME on the beta version of Catalina by clicking the installer, you may see the following warning message and the installation of FREEDOME fails: "Freedome.pkg" can't be opened because it is from an unidentified developer.
If you click the FREEDOME installer with Control key pressed (or right-click the FREEDOME installer) and select Open, you may see the following warning message: "Freedome.pkg" is from an unidentified developer. Are you sure you want to open it?
If you now select Open, FREEDOME will be installed and will function normally.
This also affects the automatic updates of FREEDOME. When FREEDOME downloads a new version from the update channel, updating will currently fail with the "Update cannot be installed" error message.
F-Secure is working on this with Apple so that FREEDOME would be notarized and identified by macOS 10.15 Catalina as soon as possible.
Note: The beta versions of the operating systems aren't officially supported by F-Secure.
