mavericks verification code window problem
Hi, there hasn't been looking any new update on my macbook so I wanted to reset it to fix this problem. However, when I erased mavericks system, I tried to reinstall the system, and apple id and password window showed up. I entered my apple id and password and clicked continue button but it required a verification code; a verification code appeared on my iPhone but there was no window to enter my verification code. And now I don't know what to do. I can't use my macbook right now. Please could you help me about it?
