Hello,

I have an issue with macFUSE and I am hoping somebody has an idea of what's going on! I have some code that mounts a drive on the user's system, and when an image is added to the drive, it is uploaded to our API. It works fine on Windows (using Winfsp), but I cannot get it working on Mac.

When I copy a file into the folder using Finder, I get an "Error -43: The operation can’t be completed because one or more required items can’t be found." The file does not get copied or uploaded.

When I copy an image into the folder using the command line, I get 2 errors: "Input/Output Error" and "could not copy extended attributes to [filename]: Operation not permitted". The file DOES copy into the folder and upload to the API, despite the errors.

I can upload some code, but I want to know if anyone knows where to start? Or if you've seen this kind of issue before?

Thank you

Cristian Marius

Hi Lucas,

It might be because of the extended attributes.
I remember I hit my head against this.
Implement the extended attributes callbacks, and if I remember correctly it should go away.

Just a follow up,
You can even get away with just implementing the callbacks; without any logic and just returning no error.

Good luck!
