Updating a rooted GS3 OTA?

[Samtheman7]

Hey everyone,
About 4 months ago, I rooted my AT&T GS3, with the intentions of putting CM10 on it. However, I've realized that I have no real need for a custom ROM, as my phone already does everything it needs to. In addition, I don't want to risk bricking my phone.
Yesterday, I got the notification for an update to Android 4.2.1, from what my phone is running now, 4.1.1. Honestly, I have no intention to add a new ROM now, and I really just want the features of the new update. So, my question is, if I update the OS on a rooted phone via an OTA update, is there any chance of my phone being bricked or all of my data being wiped? Overall, is it completely safe to update? Am I better off using Samsung Kies on my Mac?
Thanks.

Because you rooted, accepting an OTA can most likely brick your device. Kies probably won't do anything, due to root. You can flash the original ROM via ODIN.

But I'm not running a special ROM right now, nor have I, ever. I simply rooted it, and then let it sit rooted. It still runs the original Samsung ROM.

You can try to unroot via the superuser app. But it is hit and miss.
