Good morning, everybody! I recently started using my 1.33GHz 15-inch PowerBook G4 when the video card in my Early 2011 MacBook Pro decided to play dead. I'm supremely impressed by how much I can still do on Leopard One thing I've noticed while surfing the web is that WebKit is constantly telling me that certificates for many sites aren't signed by a trusted authority. Is there a place to find and install the latest certificates? Can I export them from a newer Intel-based Mac and import them into Keychain on the PowerBook?
