An Apple ID verification code in app store
I'm using MacBook Pro (Retina, 15-inch, Mid 2015) with OS X Yosemite v10.10.5
I try to download the Macos high sierra from the app store but I was failed to login. An verification code was required when I was trying to login but I don't know where to enter it when I receive the code from my iPhone.
Can anyone fix it?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
