My macbook died the other day and I brought it in for a quote to get fixed and they said $400 to replace hard drive and sata cable. This seems outrageous, so I want to try to fix it myself. The computer still boots into recovery but disk utility cannot find the hard drive. So if I replace the hard drive and cable will I be able to install the OS from online? My only worry is the new hard drive will not be recognized and I won't be able to do anything with it. Thanks for your time.
