Does anyone know how to fix this? A while back OS X started adding a "(2)" to my computer name. (See below.) I've tried deleting the "(2)", I've tried changing the computer's name various times, but the "(2)" always comes back.
Since this computer is the only with this name on my network, I don't understand why it insists on adding a "2".
Does anyone know why it's doing this and how to get rid of it for good?
.
I, too, began receiving the dialogue box notifications that my computer had been renamed to "2". I was worried that we were possibly being hacked. This had happened several times at our old house, before we moved to a new home... and changed to a new ISP (sounds like Con-cast). I had previously used Ethernet most of the time, and my wife used our router's WiFi. Didn't quite put 2+2 together.
In our new home, we used WiFi-only for the first two months -- until recently, when I switched back to an Ethernet connection. With both my wife and I using WiFi, there was never an issue.
However, as soon as I switched back to Ethenet, I started getting the dialogue boxes, again... because my wife still uses WiFi, anywhere she's comfortable. Still didn't put 2+2 together until I began looking through several Mac/Apple-related forums.
Went to CNET at this link:
http://www.cnet.com/news/tackle-a-macs-name-changing-with-sequential-numbers/
--and received their reassuring message.... The dialogue pop-ups are arriving, again, because we are using 2 forms of access -- and the computer is adjusting to allow for it.
So, I'm more relaxed about it now, though we are still going to test it out to see (under both set-ups -- WiFi only vs. Ethernet and "Wife"), if the messages return (and the renaming happens again) under WiFi only. Now that I've reset the local host name, I won't worry about it. However, if the computer renames to "3" I'll be concerned.
Hope this helps (and makes sense).
