Someone just helped me out because I had a similar problem (my computer was named "unknown device" on "find my iphone").
Check your system preferences under "Sharing", then see if your computer is named. It's likely named "Test's Macbook (2)", and so if you erase that you can name it whatever you want.
Hope this helps...

That was exactly what I needed! So much better now... I know things like this can see small but it was really niggling at me that I couldn't figure this one out. Thanks so much!

Great, thanks so much! This was exactly my problem, and you have no idea how little help I found on this point from Apple or any other "official" source of wisdom about things Mac. I really appreciate the assistance.
