Operating system won't download
Just put in a new hard drive in my MacBook pro. The hard drive is a 500GB 5400 RPM western Digital SATA. I went to install Mac OS X that came with the computer initially, and wheni select englishas my language, a pop up states it cannot not be installed on this computer. So I'm wondering if I screwed up the hard drive install, or if I need togo buy another Mac OS install disc.
Is this a good question?
