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

Just to clarify, my easy fix was simply to download and reapply one the latest combo updates to the OS I was using, not a full erase+reinstall, and not installing a new OS. It should not harm anything on your system, it's pretty easy and worth a try. For OS 10.8.5, I guess the file would be here: http://support.apple.com/kb/DL1676?viewlocale=en_US&locale=en_US

I am not able to get email for three of my accounts and it's been a long time. I have no idea who to call or how to get help.

What should I do?

I tried to put in a screen shot to show you what it says 'the certificate has expired'

Okay very weird... waht is this **** thing! It's back and I used canucksgirl01's terminal command. It cleared for a day. I was adding an opt in form for my website through a plug in and it kicked back in. I have run the terminal command serveral times, cleared the history, ran it again and it still happens. Its like a virus that finds me again.

Installing 10.8.5 update worked and fixed it this time

Grrrr its back again! I rean the thing in terminal and the **** script keeps running. where does this thing come from?

thank you very much this has been annoying me for a long time and it looks to finally be gone. i ran the keychain test and verified on my macbook pro and it worked. and as i like to quote... "people helpin' people... powerful stuff!" 🙂

Again, I have repaired key chain, run the terminal command, updated current OSX and deleted all browsers and reinstalled ... the error still plays on some of my websites. Very frustrating. If anyone has another solution that works after that let me know.

It always will on a few websites that don't have valid certificates for some reason, until you agree to trust those sites in spite of their certificate. If this happens with many sites, then I would agree that you have a stubborn issue.

This is sporatic on some sites but one of them is my business website. How do I crate a valid certificate for the site so it does not do this? I imagine I add it to keychain somehow but how do you do that for specific sites?

update date and time and have proper time zone … fixed mine instatnly

Great! Everybody should certainly check this, but unfortunately it doesn't seem to be the universal fix for all situations and/or certificates.

This certificate error problem has just begun happening to me in early 2015, in on many, many webpages across a range of embedded URLs: Facebook, youtube, tumbler, and other less ubiquitous urls.

it is happening under Safari on both my MBP with Mavericks, and my iPad with iOS8

it is happening in my home as well as outside (in a public location with probably a different ISP than at home)

I have tried many solutions suggested here or on other threads on this topic things:

cleared various caches

deleted various plists

updated and confirmed the sync of the time on my hosts and firewall/router

when I inspect the certificates being flagged, they sometimes are issued by fairly obscure sounding authorities in odd places. I know this doesn't necessarily mean trouble, but a Facebook cert from a xxx.ru issuer ?!? It does make me afraid to just click "always trust".

this is making surfing and internet use really difficult

How do these system root certificates even get into my computer, through Apple Safari updates only? Can a hacker sneak rogue certs in there and then use them to do naughty things? Can anyone point to some article or help forum which really explains the problem thoroughly and provides a real fix?
