Hi I need some help - I bought a late 2013 15' Retina Macbook Pro and it came with 10.9.0 build number 13A3017. Now 10.9.1 is out, and I wanted to download the full installation image and burn it to thumb drive and do a full clean re-installation. But I just found Mac App Store doesn't allow me to download the full installation image, and my 10.9.0 can only be _upgraded_ to 10.9.1 with the 395MB incremental update package from http://support.apple.com/kb/DL1712, this upgrade package is described as "It includes all updates from OS X Mavericks 10.9.1 plus system specific enhancements to improve the stability and compatibility of your Mac." So maybe the full 5.29GB 10.9.1 on https://itunes.apple.com/us/app/os-x-mavericks/id675248567 is not compatible with the 2013 15' Late Retina Macbook Pro? I just downloaded the upgrade package from Mac App Store and now I'm running 10.9.1 build number 13B3116 So my questions here: I really would like to do a clean full re-installation of 10.9.1, where can I get the full installation image which is compatible with 2013 15' Late Retina Macbook Pro?
