I was able to update my Asus G50V that I had 10.9.0 installed on to 10.9.2. I used the built in software update and it downloaded, installed and worked with no problems. I still have sound as well. I did repair disk permissions after the update.
I have successfully installed Mac OS X Mavericks on my Asus G50V-X1. I wrote a tutorial on how I did it. You can check it out at my website: www.JeffReviewsStuff.com
It works great and I am really enjoying using OS X.
