Hello @Henkele
Thank you for your question.
The reason the VPN function is not working on your macOS is that it is running an older version. We updated our VPN system on January 2, 2025, and older versions of Freedome or F-Secure Total VPN apps are no longer supported. As a result, these versions may get stuck in the "Connecting…" state. We recommend updating the VPN app to the latest version to ensure proper functionality. For more details, please refer to this article: Update Your F-Secure VPN by January 2, 2025.
The minimum required version of the F-Secure app is 19.6. However, since you are using macOS Big Sur (11.7), support was discontinued in version 19.4. Additionally, for security reasons, older versions of the F-Secure app are no longer available for download.
Hence, we strongly recommend updating your macOS to a supported version to ensure compatibility and security. For more details on supported operating systems, please refer to this link: System requirements.
Please let us know if you need any further assistance.
Thank you and have a lovely day.

To buy 3 new Macs is out of the question as they still works fine and Macs are not cheap. It is not impossible to send me a link to download the F-secure version 19.1. That the version is unsupported is ok by me. I have used F-secure ver 4.x and forward until year 2007 in my old company (70 licenses) and the last 17 years in private for 10 licenses. Do I have to change that? Best regards Henrik
