Mac system, git just checkout out of the file, a check, found that has been modified, how to break???

In fact, nothing has been done since checkout, and why have these files been modified?

Check the other computer stored on the same set of source code, the original problem files are the same name file, but there is a case to distinguish it!!!

Some netizens say you can reformat the hard disk, choose case-sensitive format.

In fact, this may pose some pitfalls, such as some applications may not be available.

So my compromise is to create a new partition specifically for the code that uses the file name case sensitivity.

Internet a search, found that a netizen also encountered a similar problem, are under the Mac to engage in Linux:
