Guys, I did TM recovery back to Mavericks and cannot sign in to iTunes (Apple account). It shows an error connecting the server and to try again... tried many times. And just after couple if hours it connected. After that install again 10.10 and - the same issue - still cannot connect to apple server for hours now... any ideas why such problems after clean install or recovery ? Maybe Apple ID / iTunes server has some time out before which time cannot login again? Or what... strange
