Airport Extreme - Operation Not Permitted
Hi,
Over the weekend I rebuilt my MacBook (with El Capitan), and everything looked fine until I tried to run a backup from my external drive to my 2TB Airport Extreme.
even a sudo chown -R <myuserid>:wheel /Volumes/Airport/* gets "Operation not permitted"
I have disabled csrutil and rebooted but I cannot seem to get passed this error.
Is this somekind of ACL issue? I really need to be able to copy from the external drive to the Airport
MacBook Pro, OS X Mavericks (10.9.3)
