This was an easy installation. I am NOT a tech type, just a mom who wants a better hard drive.
I installed the new hard drive into the MacBook and moved the old hard drive into the new housing in less time than it took my husband to put the baby to bed. Yeah, his bedtime routine with her takes longer than mine, but it's still less than half an hour.
I just cleared off part of the dining room table, put down a towel to keep all the parts from rolling around and followed the step-by-step directions provided here. Sooo easy. Almost too easy.
I look forward to my next MacBook repair, and I will absolutely come back to ifixit.com to get the parts and learn how to do it. I'll be here for support on my iPhone and iPods, too.
