Mac OS X 10.10.3 File Permissions<br />
<br />
CMD-I for .jpg file returns for Sharing and Permissions:<br />
<br />
[Owner] (Me) - Read &amp;&nbsp;Write<br />
Staff - Read Only<br />
Everyone - Read &amp;&nbsp;Write<br />
<br />
Attempt to change Staff to ‘Read &amp;&nbsp;Write’ returns: “This operation cannot be completed because you don’t have the necessary permission”<br />
<br />
What is ’Staff’ and why do I [Owner] not have permission?<br />
<br />
This makes no sense to me - if I own the file and have given everyone R/W permission - what role does ’Staff’ play?<br />
<br />
My goal is to copy file(s) from Mac-1 to Mac-2 over CAT5 local network
