Why can't I get past step 4 of installing Mac OS 10.5?
I have a macbook A1181. I bought a Toshiba 500GB 2.5 in internal hard drive from ifixit, and I installed it. I now want to install my OS X , but when I get to step 4 of the process, I don't see my hard drive listed, but one that says it is Toshiba 3.6TB. Also, when I go to partition it, it says that the Partition: unformatted. I don't know what to do from here, as it doesn't match anything in your directions.
