Cannot sign in to app store
I have MacBook with old version(10.10.5) and I am trying to update it from the app store and install the macOS montery but when I sign in to my apple id it says that the password is incorrect( but it is correct actually) I think this is because this mac is not trusted and cannot receive apple id verification codes . so how can i fix this?
MacBook Air 11″, OS X 10.10
