com.apple.webkit.networking.xpc wants to sign using key "apple ID Authentification 2014-13-13 13:08:07 GMT-07:00" in your keychain.

I just got this today while looking at an image in Google using safari.

I've seen people have similar issues, not sure about this one.

I clicked allow just to get rid of it at least temporarily.

Whenever I have an issue with certificates Apple (we don't) Care's solution is to install Yosemite because that has improved security. I say better the devil you know. Some other Apple genius told someone to use Chrome.

As long as this doesn't hurt my computer am I ok? Maybe I just need to switch to Firefox and be done with it.

All these certificate issues started a few months ago.
