Unity VS inconsistent line endings（record)

WARN：

      There are inconsistent line endings in the 'Assets/Editor/Script_03_08.cs' script. Some are Mac OS X (UNIX) and some are Windows.
      This might lead to incorrect line numbers in stacktraces and compiler errors. Many text editors can fix this using Convert Line Endings menu commands.

网上查了一下都是Windows开发环境的解决方法，还没找到Mac的，记录一下问题，之后再解决。

一个绕过去的解决方法：

     不在Unity，而是在VS中创建新的脚本。
