Rating: 4/5 The drive installed easily September 24, 2016 The OWC technical support was great. I watched the videos that described the drive replacement and read about reinstalling files. This was sufficient to get me up and running without any problems.

If I had to do it again, I would purchase the solid state drive as HD installation turned out to be very simple and the attempt to repair my computer turned out not to be a futile exercise - a pleasant surprise. This hard drive matched the performance of the original.

I would recommend this item to a friend!

Rating: 5/5 Simple installation; just worked March 14, 2016 I bought this hard drive for my wife's 2008 MacBook. Installation was dead simple. I booted from an external drive. Though I had to format it in order for the computer to recognize it, that was very easy. I was able to install OS X El Capitan, transfer her information from her backup, and boot the computer. No glitches. Good price, fast delivery, just confirmed opinion of MacSales (OWC) and its products.

I would recommend this item to a friend!
