I have OS X Mavericks on my MacBook Air 13-Inch that I want to reinstall due to countless files that I don't need and I don't have the time to delete. This was downloaded from the Mac App Store so there is no install disk. So, I open up Internet Recovery to reinstall, and it turns out that the Internet Recovery is still the OS X Lion version (this is the version I had when I bought the Mac), so I can't reinstall because "there is already a newer version of OS X on that disk." Is there any way I could update my Internet Recovery so that I can reinstall? Oh, and I am actually typing this from the Internet Recovery Safari window .
