copy files on macOS X return error: "could not copy extended attributes"

[sbilly]

When I try to copy file to a utahfs-client mounted folder on macOS X with latest version utahfs-client binary, and the command cp returns with error:

# cp **** .
cp: ****: could not copy extended attributes to ./****: Operation not permitted

while utahfs-client printed following logs:

# utahfs-client -cfg ~/.utahfs/utahfs.yaml -mount ~/utahfs

This happens because UtahFS doesn't support a filesystem feature known as "extended attributes." Despite the error message, you should still see that the file copied over fine and that the error messages aren't really a problem. I'll leave this open and tag it as an enhancement in case someone wants to add support
