Certificate Error on Every Website/Browser
Hi there, I have been having an issue the last couple of days. Whenever I visit a website (about 80%) of the sites I go to regularly, I am now getting an error that "Your connection is not private". I have searched the entire internet for the answer and nothing has worked. This happens in Firefox, Safari, and Chrome....
What I have already tried/verified:
1. Date and Time are correct
2. Uninstalled browsers and reinstalled
3. Reset Keychain
4. Made sure software up to date (10.11.6)
5. Reset all browser settings to default
6. Went into keychain access and attempted to delete expired certs (deleting not an option with right click, highlighting and hitting 'delete' on keyboard, or in the Edit drop down a the top - it is greyed out).
Things to know:
- My computer has also shut down a few times (before this issue) and saying it restarted because of a problem.
- I have 2 admin desktops (one personal and one for work)
- Work desktop seems to create the issue of restarting, as well as being slow to load when I login
I have never ever had a problem with a Mac and now I am 100% lost on how to fix this...your help would be hugely appreciated!
Picture below is screenshot of Chrome browser error in random site. Again this happens in every browser I use on 80% of the sites. My bank site and Apple site (for example) do not have this issue.
