FIX for: "Safari can't verify the identity of the website" - certificate not valid

If you are getting a message like this:

Safari can't verify the identity of the website "static.ak.facebook.com" (or ANY other address)

This certificate is not valid (host name mismatch)

There is an EASY FIX for this...

Go to:

/Applications/Utilities/KeyChain Access

Select "KeyChain First Aid" from "KeyChain Access" (menu choice)

Make sure the radio button for "Verify" is selected, and then click the "Start" button.

Once completed, it will tell you if any problems were found just above "Verification Completed".

(In my case "no problems found").

It is not necessary to perform a "repair" if no problems were found.

If problems were found, follow up the verification process with the "repair" process.

FYI: "KeyChain Access" stores info for Certificates. If a "mismatch" occurs, or a certificate is deamed "invalid" you get a warning. (This is part of your security). Performing "KeyChain First Aid" will verify ALL certificates and correct any "mismatching" by updating the certificate OR will tell you there was a problem (ie. a website using a fake certificate), in which case you need to follow through with "repair" and if necessary, not use the problematic website. BUT, in most cases, this message is NOT about anything malicious, its just part of the security settings that are trying to ensure ALL certificates associated to ANY website is correct, and since certificates expire and/or get updated, these conflicts can occur.

I had problems starting today. No solution yet. My problem started with trying to access itunes, at first "internet radio", then the store. I get the certificate warning that is being discussed. I then tried to access this forum from Safari and got the certificate warning there. However, with Firefox I am able to get access. My date and time is correct. I verified keychain access. I'm stumped.

And I can't access the App store to update either Safari (which I just updated) or iTunes.

This discussion is almost three years old now and probably involves a completely different version of OS X and Safari. I wouldn't be surprised if there isn't anybody else monitoring it any more and I don't really know why I am.

Any time you can't find a solution in an old discussion, start a new one in order to attract new troubleshooters to it.You'll get better help faster that way. It's just how this forum works best.

FYI that, at least in my case, there is no KeyChain First Aid option under KeyChain Access. However, I reset my keychain and it solved the "can't verify identity of website" error that I was getting on multiple sites in Safari.

What do you mean by "reset my keychain"? I've been getting this issue in macOS Sierra lately but only for a few website, who then go on to not load properly, not display images, or redirect me to an ad... This is really annoying so I'm hoping to find a fix!

Thanks

I followed the instructions here: Reset key chain

Hope it works for you too!

Thanks for the quick reply! Does that delete all my saved passwords or just change the password I use to access them?
