Hi all.
As I can see, this problem is not from side of software vendors solved yet.
I was searching on another forums too. I tried more solutions but without success. (DNS recovery and change, Cookies cleaning, searching for updates and so on) Using Chrome is not the option on MacBook Air because of the huge installation. I deleted Chrome with almost 4 GB :-(.
I`m on Intel based Mac 10.9.1 (so i cannot downgrade to lower version) & Safari 7.0.1.
Did you find some solution?
