F-secure Safari Extension not working on macOS Mojave (Safari 12.0)

I installed latest macOS Mojave 10.14 Public Beta. This macOS version has many security updates eg. Safari no longer support dangerous legacy extension from webpages (outside Mac AppStore). Safari 12.0 on macOS Mojave support only trusted extensions from Mac AppStore. I suggest publish your F-Secure browser extension on Mac AppStore.

    Hello Everyone,


    As updated in the above article, SAFE for Mac 17.4 has been released, and we have started the automatic updates. If don't want to wait for the automatic update but want to install the latest version immediately, log in to your My F-Secure and install it manually. 



  • Dear F-Secure community,


    It seems like the issue raised by Pawel still exists. Even now that the final macOS Mojave has been released. Is there a way to tackle the below error?

    Hello NADER,


    This is a known issue and our development team is working on the solution. The fix should be ready in SAFE's next release (17.4). Although there is no fixed date for the next SAFE release, you can expect it in October 2018.


    Please have a look at this article for more information.
