i cannot use my apple id and password on my macbook air app store
I am trying to enter on my App Store in my macbook air and it replies that my apple id or password are incorrect. However this is not true, because I changed it and I am using my info on my iphone (app store included). Please HELP, I don't know how to solve this. I have changed my password 2 times already.
MacBook Air 13″, OS X 10.10
