My iMac cannot access a specific website, but my MacBook Pro can
Mac does not access a website with recent server change using any browser but McBook Pro & general public can and do! Conducting a ping test shows it is targeting the previous server's IP address. Deleting Mac DNS cache doesn't appear to help. What could be wrong?
