Ethernet problem - i can't login in App store
Hi, I've tried to download Osx Yosemite from app store but i can't log in, it gives this error 'Your device or computer could not be verified. Contact support for assistance.'
I found that if you have not a working ethernet you can't login, well a year ago my two ethernet ports are broken along with my router and a hub ethernet cause of a lightning strike and i'm using wifi adapter since then.
So how am i be able to login to app store, or anyway download Osx Yosemite?
Thanks in advance.
P.S. my mashine is Mac Pro 3.1 2008 with Osx Mavericks
Mac Pro, OS X Mavericks (10.9.5)
