Downloaded the latest Anki for macOS and when I start it, a terminal appears with this text:

I am using a work machine to do this, so it’s entirely possible some work-related firewall is getting involved in the cert negotiation, but I haven’t seen cert-related issues with any other applications I’ve installed on this machine.

I’m happy to perform a workaround here; is there something I can run manually in the terminal to get this working?

In the meantime, downloading and installing version 25.02.7 (released June 6, 2025) has resolved the issue.

I had a similar issue in windows 10, also using a corporate network. I created a topic yesterday about it: Installation error - invalid peer certificate - --native-tls? - #3 by cortante
