(Just to record)
What should I do when I can’t delete the old Game Center account created by my old Apple ID on Mac, after signing in with my new Apple ID?

- First download a game which needs Game Center, Bomb Squad for example.
- Open the game and it would require you to sign in Game Center. Then sign in with the old Apple ID.
- Back to the Internet Account in System Preference. You would find the old Game Center account back to normal.
- Then you can finally delete it.

今天解决了一个macOS在Game Center账号的问题，现在记录一下。问题表现为我将原来的苹果账号A登出，然后登录新的账号B，但是原来A的Game Center账号一直在互联网账号里面赖着不走，显示账号名称为Unknown，点减号也无法删除。

解决方法如下：随便下载一个需要用到Game Center的游戏，例如我下载的BombSquad。进入后，用原来账号A来登录Game Center，成功后回答互联网账号，这时会发现老赖账号显示了正确的昵称，这时候就可以点击左下角减号删除了。然后至于要不要用新的账号登录Game Center，那自己决定喽。（我要不要用英文也写一段，因为今天搜谷歌的时候发现挺多人有这个困扰的）
