I upgraded to Mac OS Sierra and every thing just got broken down. I took my Mac to technology center and they reinstalled the OS. Now after I have installed EN application, its taking hours and hours to retrieve data.
The problem is: I live on campus. I use campus network system because I am not allowed to buy private internet link. Campus network does not allow downgrading to El Capitan and if I do so, my machine will be blocked. I am writing PhD dissertation and every single minute of my life is so so so important to finish my work as soon as possible. Your imprudence is costing me invaluable time that you can never even imagine of it. My all work is lying apart and I can do nothing. Would you please, for God sake, respond???
