Hello! Today I have got my first mackbook air 13 2017. And I have got lots of questions about it. First, how do I download an enhanced version of the voiceover voice? I tried to launch the voiceover utility, interacted with speech, but than I saw a dialog like configured languages and there was Russian language. But I cannot find the way to download an enhanced version of voices. Also, I couldn't understand how to use appstore. There were lots of links like featured apps, but I couldn't find the search field. What should I do to find it? I need to download Skype to my Mac. Any help would be opriciated. Thank you!
