问题
Recently I wanted to archive my App with Xcode, then Xcode said that I must input my Apple ID and password again. Perhaps my login information was lost. I tried again, but it always failed.
If I input a wrong password, I get a correct response:
It said my Apple ID or password is incorrect. That can prove my network environment is okay.
However, if input the right credentials, it would respond nothing but only show busy:
I have tried a VPN to solve this problem but nothing works. Who can help me?

I probably find the answer.
Hangs when trying to sign in using Apple ID
My macbook is secondhand, I don't know why it doesn't have a serial number. When login with Apple Id under El Capital(Mac OS X 10.11), the system tries to check the serial number then my mac hangs.
That's not only the Xcode problem but also AppStore and other places need to login with Apple Id in the system.
I have two options to solve this problem. one is recover the system to 10.10, another is go to apple store to fix it.
