MacOS Version 10.15 (Catalina) has instituted new security procedures that require all software to be “notarized”. This procedure, similar to software signing on Windows, assures that the software comes from the expected developer and has not been compromised.
The new version of Stat/Transfer (version 15) is properly signed and notarized. Updating is definitely recommended. In addition to all the other benefits, you can save yourself the hassle of what is to follow. If you choose not to update, you can install Stat/Transfer version 14 by following the instructions below.
If you are trying to install a copy of Stat/Transfer 14 on MacOS 10.15 and are getting an “Unknown Developer” message, we suggest you proceed with the installation, since you will have a chance to verify the installer itself.
In order to continue after getting the warning, you can go to "System Preferences" -> "Security & Privacy". At the tab "General", you should see the message "st_installer14.pkg was blocked from opening because it is not from an identified developer.”
To continue, click the "Open Anyway" button and the Stat/Transfer installer will open.
On the first page of Stat/Transfer installer you will see a small lock in the right upper corner. If you click the lock, MacOS will display information about the certificate used to sign the Stat/Transfer installer as shown below:
The Stat/Transfer 14 installer has been signed using the certificate issued by Apple to Steven J. Dubnoff, the founder and owner of Circle Systems, the developer of Stat/Transfer.
If you are satisfied with the aforementioned security check (you should be!), continue installing Stat/Transfer as usual. The screenshot below shows a copy of Stat/Transfer 14 installed and activated on MacOS 10.15 Catalina:
Stat/Transfer version 15) does not have this problem, and you can fix it by updating.
