Having some issues getting my MacBook Pro updated to OS X Mavericks. I have a MacBook Pro 1,1. I have been reading all over the internet. I followed Tiamo's guide, a thread on SuperUser titled "How to upgrade Mac Pro 1.1 from OS X 10.6.8 to OS X 10.9 Mavericks?", and various threads here. I think I have followed both accurately to create the boot drive and edit the files within so it can work with my MacBook Pro 1,1. Currently when I try to boot off the thumbdrive I see a blinking folder with a question mark on it. Shortly after that I just see the apple logo and it hangs there until hold the power button down for a hard reset. I can then boot back into 10.6.8 just fine. Looking for any tips to get the installation going. I am using the Install OS X Mavericks version 1.3.46; as reported in the properties of the installer, to make boot disk from. Been working on this one for about eight hours. Figured it was time to ask for help. Thanks in advance.
