Unable to Update AVG

Hello Harry,
I'm sorry to hear about this, please send us a screenshot of the error message (which you're receiving while AVG updates) to assist you better.
Best regards,
Alok.

I sent you a screen shot. I  am still unable to update my AVG Anti-virus.

I am repeatedly getting the message "No connection to upate server". Why? I am connected to the internet. Using Macbook running Sierra.

Thank you. Everything is fine now.

I  have tried to do as you suggest 3 times and nothing happens.
