Hi,
The problem was: failure to replace yahoo by Google search engine.
installed the malwarebytes, found 15 adware threats, Chose quarantine then delete.
Then tried to test and I opened safari to check whether google is the default search engine or no. And I found that I cannot connect to the internet I got always the message “ safari cannot to connect to the server” I tried to open google, facebook or apple support and I failed.. also I connected my macbook to the hotspot instead of my wifi and didn’t work too
so removing or deleting any of the threats is related to this problem?
thanks
