Your connection is not private

I have an iMac, OS X 10.9.5.


Since yesterday I have been having the privacy error "Your connection is not private "ERR_CERT_DATE_INVALID on many websites that I would normally have access to normally.


I tried clearing browsing history and cookies. I tried accessing those websites using Safari. I restarted my Mac many times, after trying these options. None of them work!


On a different note, my Mac is not incompatible with most apps under the Sun. I understand this is Apple's sale method, but I don't appreciate having this privacy issue on top!

For mac's running older versions (pre 11), a specific root certificate expired on September 30, 2021. I've searched board after board and here was the only thing that fixed it:

I can Confirm a fix that worked on both a 10.9.5 & 10.11.6 Mac OS users. Simply set the DST Root CA X3 to "Always Trust" on several Mac's I manage in an office and home's this fix work for 4 websites that previously had issues with this CERT ERR.


Directions for fix:

  1. Open ~/Applications/Utilities/Keychain Access.app
  2. From View menu select "Show Expired Certificates"
  3. On the Left Sidebar pick System Root
  4. In search bar top-right type DST
  5. Double-click "DST Root CA X3"
  6. In pop-up, turn down "Trust" arrow and set "When using this certificate" to "Always Trust"
  7. Close the pop-up and put in an Administrator user/password info.
  8. Close all open Browsers & Keychain you should be good to go after that.

Why am I able to have access to Facebook, Youtube and many other web pages in that case?


The last time I checked, I wasn't able to do any software updates. So Apple won't allow me to update the software which is incompatible with many apps I used to be able to use, and won't bother working on OS X 10.9.5. to make it compatible.


My Mac is an iMac, 21.5-inch, Mid 2010, if this is what you are asking.
