So I recently purchased the Momentus XT for from new egg for my unibody macbook. However, I didn't really think about how I was going to get the drive INTO my computer. Apple wont do it, which shouldn't surprise me. I went to best buy and they told me that installing a new drive (not apple) would invalidate my apple care. Do I go to a smaller store? That worries me, I don't want them to mess up my computer. Should I even bother bc this invalidates my apple care?! Suggestions would be amazing!
