Q: Internet weirdness after 10.11.5 upgrade

Hi

 

My 15" MacBook Pro (Mid 2010) upgraded itself to 10.11.5. I'm now having problems with its internet connection. The clock thinks it's 2001 and doesn't respond to changing the time server or any other attempted adjustment. I ditched the World Clock preferences with no effect. Safari can't verify any certificates so every website visited has to be manually Okd. When I arrive at a website CSS doesn't always work so that sites display in blue Times Roman. When I tried to reinstall the OSX using Recovery it errored when trying to validate my machine with Apple.

 

The only common factor I can see here is the internet, but it's working just fine for all my other devices and the MBP seems to be fine with its connection.

 

Any ideas what to try next?

 

Thanks in advance.
