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!

That's what I tried initially :) I really appreciate you trying to help but the link you provided takes me to https://apps.apple.com/app/macos-high-sierra/id1246284741?mt=12 but it is saying "Connecting to the Mac App Store" and nothing else is happening.

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:

Thanks to Qchrontech on LetsEncript board:

https://community.letsencrypt.org/t/connection-errors-on-apple-devices/161107/27

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:

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

Welcome to the Apple Support Communities.

This issue is due to the fact you have an old version of OS X (now macOS) and chances are, modern webpages won't work with it.

What year is your iMac? You may be able to upgrade to a new version of macOS.

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.

Firefox not available due to my Mac's OS X 10.9.5. High Sierra link is not opening, it looks like it is still loading. I know that I am using an old version of Chrome, but the new version is not compatible with what I have, so I don't have any other option, or do I??

I tried searching for high sierra in the app store on my mac. When I typed in high sierra, it automatically suggested macos high sierra. When I clicked on that suggestion I had no results. It says "Your search had no results. Try searching again".

Your Mac is officially obsolete and therefore insecure by definition. Dispose and replace with new asap. Important: do not gift to neighbor, nephew, niece, colleague, subordinate, friend, or relative.

If it can be upgraded to macOS High Sierra there's no need. :-)
