The OSX version of sed is not the same as those found in most Linux systems.

It extends the -i option to give you the opportunity save a file with a different extension, but requires input for that extension.

If you just want to overwrite the file in place, you need to use sed -i "" ...sedCmd.... fileName to rename your file in-place.

Per @JamesMcMahon 's comment, see here for the full doc for OSX/BSD sed.

I hope this helps.
