I’ve been getting an error when trying to copy files from an external hard drive connected to my mac.
The operation canâ€™t be completed because the item is in use.
From reading this postÂ I found the problem may be coming from a list operation that is using the file and not closing out properly.
To fix this I opened the terminal app on my mac and entered:
sudo lsof | grep /Volumes/Seagate\ 3TB
the “/Volumes/Seagate\ 3TB” part is the path to the external hard drive. The easiest way to find this path is to type the command followed by a space so “sudo lsof | grep “, then drag the icon for the external hard drive from your desktop onto the Terminal window, then hit the return key.

This seemed to do the trick.
