Write method not called

[nickcone]

So I currently have my file system fully working on Windows, I can add/delete files/directories and everything works as it should. When I run it on Mac and copy a file to the file system, the file does not appear on the file system because the write method is never called. Has anyone ran into this before or does anyone have a solution to this issue?
The order of operations on windows is: Open, create, open, getattr, write, getattr, release.
The order of operations on mac is: Open, create, open, getattr, release.
I can provide more detail on this if needed.

Update: When I use the terminal to copy or move files to the file system, the write method is called. However, when I drag and drop them into the file system, the write method is not called.
