Safari can't verify the identity of the website

This message comes up every time I try to log in to my bank, ebay, paypal, vodafone, hotmail, etc. Basically everything I try to log into. It tells me the certificate is invalid, or the issuer is invalid. This just started one day a little while ago. I have all these pages bookmarked and safari used to be fine with them. I downloaded firefox to see if it was just a safari thing, and it did not have this problem. Can someone please tell me how to fix this with safari? Version 5.0.1

MacBook Pro, Mac OS X (10.6.4)

HI and welcome to Apple Discussions....

From the Safari Menu Bar click Safari/Reset Safari. Select all the boxes. Then from the Menu Bar click Safari/Quit Safari.

Now relaunch Safari. Try logging into one of those sites.

If that didn't help, try troubleshooting the Safari .plist file.

Open a Finder window. Select your Home Folder in the Sidebar on the left. It has a small house icon. Then open the Library folder then the Preferences folder. Move the com.apple.Safari.plist file from the Preferences folder to the Desktop. Now launch Safari. Navigate to a site that normally has a signed certificate like your bank. If you can do this without the invalid certificate dialog, move that .plist file to the Trash.

Safari can't verify the identity of the website "daw.apple.com" ... Expires: Saturday 5 January 2013 ... This certificate was signed by an untrusted issuer"


This is the message when I sign in to this forum. This is an APPLE problem, not a user problem.


It is a dangerous security problem to get us all ignoring the security warnings, especially when they are on Paypal or bank sites. I have switched to Firefox for this kind of work now. It seems to be doing just fine. No garbage messages.

I have no answers, but am having the same problem and I hope that adding to the thread may help us get some attention. It affects both Safari and Chrome for me, but not Firefox and I've tried every suggestion from the thread with no success, although I'm running Lion and I think some of the earlier posts were for earlier operating systems (i.e. I can't find a safari plist file).


Apple, please help!

I had this problem also.

Starting safari and going to the default apple page (http://www.apple.com/startpage/) would throw an error about a facebook certificate.


In addition, when this problem happened, I would loose all my safari extensions.


It only happened at work, connected through the work firewall so something was probably getting messed up by the firewall.


For me the keychain fix worked, specifically, open keychain, command-, for preferences, click the certificate tab and set Online Certificate Status Protocol (OCSP) to off.


It immediately fixed the issue with facebook and I was able to re-install my extensions. Which I used to have to wait until I was off the network to fix.

I just wanted to update this thread that I found a solution for me on another thread. It looks like my problem with the certificates was a bug in Lion. I was also having difficulty connecting to the App Store to download Mountain Lion for an upgrade. Here is the thread and here is the blog post that I found on that thread with the instructions that solved my issue. I hope this helps someone else too! Good luck!

I've been having this problem in the past month or so, and finally decided I was annoyed enough to read up a little.


I opened the Date/Time setting in System Preferences and it was already checked to update automatically, so I just locked the Control Panel and went back to my business on Safari and so far it's worked!? I didnt do any of the plist, resetting or Keychain stuff.


I cant explain why it worked, it could all happen to be a fluke, but I'll keep you posted if it comes back.

@Cliff-R - how do you delete or change the keychain certificates? After reading all the certificates that have "trusted access" to my computer I was hoping to delete the ones that look suspicious - like AOL having a certificate that lasts until 2037 - really? I don't remember saying that was OKAY. I'll be making Safari ask me everytime from now on.

The problem might of went away but you did not solve it. My date box is checked and the problem still comes and goes. I believe it is associated with either the router or your ISP. Truthfully it is beginning to *&^! me off because it is happening more and more. Sadly I never had the problem with windows so I may be forced to abandon mac products since NO ONE can provide a reasonable solution.

Sep 20, 2012 4:57 AM in response to RussyPlum

Ok. I tried every possible solution mentioned in this thread over the past year (and some extras). Keychain deletions, automatic date, and some of the more complicated solutions. I even, as suggested by one poster, wondered if it was my router or IP address. Although sometimes I would think a solution had worked, it was only a cruel tease, because eventually the "cannot verify" warning would come back.


Nothing worked. I became convinced that this is a SAFARI PROGRAM ISSUE AND OPERATING SYSTEM GLITCH that Apple has absoutely failed to correct.


So, what finally corrected this issue? I bought a new Macbook in February of this year (for reasons not related to this). I now have an operating system of 10.7.4. No need to set or unset automatic date, no messing with the keychains, no nothing, I never have this warning. Clearly, my new Macbook's operating system runs Safari without glitches. And so no - it was NOT my router, my internet provider, anything external to my Macbook, or anything I could control.


Pretty expensive solution if you ask me.
