I literally got this macbook last week and I was using iMessage perfectly until I had to update it. When I open the app, nothing shows up, and when I go to the file tab, the cursor becomes the loading colorful circle.

HI,
Can you go to the Apple Menu in the Menu Bar > About this Mac and then click twice on the line that reads the current OS ?
This will change to the Build Number (another OS counting method) and then to the Serial Number.
At OS X 10.8.2 (in Mountain Lion) the Serial Number started to be used in creating an Auth Token for both Messages and FaceTime.
One issue is that (after the initial issues) people have been updating from Lion to Mavericks, bypassing this "threshold" as it were.
However someone has also reported that Mavericks seems to deny access to reading the Serial Number from the logic/Mother board and creating the issue over again.
They reported that taking it to the Store and having it "flashed" to the board is successful.
(they had been in contact with Apple and engineers were looking at various Logs that "proved" it was missing).
There are some utilities available On line (which I will not recommend) that do allow you to attempt this once.
It seems the board only allows this once.
However the info in the other thread seemed to suggest otherwise.
If there is no Store near you try an Apple Authorise Service Provider (AASP)

After the update, I have not been able to use iMessage on Mac.
