Rating: 5/5 Pretty easy March 4, 2017 After an internal hard drive failure on the 2011 iMac that has the ridiculous special hard drive and connector, I tried booting off an external drive. That was too slow so I looked for internal options. This kit was exactly what I needed. I watched the video instructions on my iPad while taking it apart and putting it back together and with the tools included in the kit, it only took about 30 minutes for the entire process. I'm pretty handy and have taken apart computers before so take that into account but I think this could be done by most people without much difficulty.

My one recommendation would be to have a second person around for the part where you take off the screen and put it back because the weight and angle are a little awkward. Not a deal-breaker challenge, but I definitely felt better having someone else support the screen while I disconnected and reconnected the cables behind it. I also recommend having a can of compressed air nearby and using it to blow out the dust from inside the computer. There will be a lot.

The machine is running better and for a 6 year old computer, I can't complain.

Rating: 5/5 All in one kit which worked perfectly February 21, 2017 This kit worked perfectly for my iMac. Everything was included. And, along with the 'how to' video on the OWC site, the install went very smoothly. The video estimated that it would take about 35 minutes and it took me about 35 minutes.

This is yet another great product by OWC. You can always count on them to help those of us with Macs.

Rating: 5/5 Sounds Difficult but it's EASY February 6, 2017 I was extremely cautious about this type of upgrade because of all the things that could go wrong. Saw the video from OWC, took my time and everything went GREAT. Now, I have so much HD space that I think that I would never run out of room. Tools worked like a champ. Thanks OWC for making my life easier to perform these upgrades.

Rating: 5/5 great value, easy to install January 30, 2017 After about four years, the original hard drive in my iMac died. Using the kit from MacSales.com, I was able to quickly replace it with a higher capacity and better performing drive for less than half of what retail shops in my area would charge.

I simply watched the video a few times, then performed the installation using the provided tools and replacement drive. It took less than one hour from the time I received the kit to powering-up the iMac and beginning the standard MacOS reinstallation process.

Highly recommended!

Rating: 5/5 Replacing a hard drive on an iMac??Not me! But I did! January 29, 2017 As the HD on our 2011 iMac failed, I was glad that I had a couple of OWC external HDs as bootable backups. This left me with the choice of having a new HD installed or try to do it myself. Looking up for a replacement solution, I came across the SSD kit. After evaluating the 960 GB SSD vs the rotating 2 TB HD solution, I chose the 2 TB hybrid drive kit. I was a bit scared to take our iMac apart, but after watching the video twice, I replaced the HD not in the 35 minutes that the video said, but in 45 minutes-I had to vacuum out six years worth of dust! This is a great kit, it had all of the tools that I needed, it helped that I had a OWC tool kit I purchased over five years ago, as I needed the tweezers from it.Thank you OWC, you saved us lots of $$$ one more time.
