Hi, i tried to install Mavericks on my Windows 7 Laptop in VirtualBox. I used this tutorial Unfortunately the installation crashes at some point. I get an Input/Output error for the file PCmyoungjo.ttf. The Problem occurs in SteamCompressor.c:1166 CloseStreamCompressor.....called after writing 3276800 bytes we were promised 9515016 bytes I would add the log, but I can't copy it. Can someone help with that problem, or is the iso file just broken?
