    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.

    Rating: 5/5 Perfect Tools for swapping out to an SSD January 26, 2017 I ordered this kit to install an SSD into my 21.5 mid-2011 iMac. Though nervous, I found the process of taking out my old spinning 1TB hard drive and replacing it with a 1TB SSD to be easier than I thought. I recommend watching the OWC videos and other videos to get the complete picture before starting (note it is easier to replace your HD with an SSD then the process of adding an SSD and KEEPING your old spinning hard drive in the machine. The thermal sensor in this kit is key to keeping everything working smoothly. Since install, I have been amazed at why I did not do it sooner!

    Rating: 4/5 The first place to start January 14, 2017 I think this kit is the best way to go when first opening an iMac, especially, if you unknowingly installed an SSD that's defective and your iMac has to be reopened multiple times. The video is excellent and should be reviewed several times before attempting the upgrade in order to feel comfortable with the process. For those venturing into this experience for the first time, there are two tools that I feel should be included in the kit that are missing. A pair of long handled tweezers with angled ends are very valuable in removing, and especially reinstalling, the screws around the magnets. Also, a pair of powder-free rubber gloves should be worn to help avoid touching the screen. Removing the clasp on the second cable described in the video is difficult, so take your time and avoid breaking it as I did and needing to use electrical tape to secure it. One of the two suction cups provided in the kit was weaker than the other, so be careful when transferring the glass cover.

    Rating: 5/5 Not that hard to install December 18, 2016 I got that kit to install a Samsung EVO 850 500GB SSD in my system. I also got the "NewerTech AdaptaDrive 2.5" to 3.5" Drive Converter Bracket" in order to fit a 2.5" SSD. I used this kit and followed the step by step video to change the harddrive, and it works without any issue! (the video is really good). I put the thermal sensor against the SSD (middle of it), even though I don't think this does heat a lot, but at least it keeps the fan of my iMac from going crazy.

    My iMac is now very quiet (not more harddrive noise) and runs really fast!

    Rating: 5/5 Rip that iMac apart! November 28, 2016 I sold my iMac and wanted to keep the hard drive - I already had a 'spare' Mercury Elite Pro enclosure and the drive has data that belongs to previous employers, but no naked pictures of my wife. The tool kit and the video from OWC made this whole process simple, fun and rewarding. I'd always thought of the iMac is pretty much impenetrable, but no longer - with the suction handles and screw drivers I could have easily made this iMac into a perfect boat anchor, but the careful guidance of the video meant everything went back right where it was supposed to and the iMac works perfectly, much to the buyer's delight. Further bonus - the buyer got to witness and help with the swap, so now he's a certified iMac tech, just like me.

    Rating: 5/5 Worked November 14, 2016 This is mainly for replacing an Apple HDD with another non-Apple HDD. It allowed me to install my SSD in place of the HDD with a thermal sensor, but it was kinda just hanging there loosely since it doesn't have a propper mount. I ran like this for a while and eventually bought the Data Doubler from this site. I put the original Apple HDD back in it's place and move the SSD to where the SuperDrive was. I'm happier with that solution so I might recommend that option over this.

    Rating: 5/5 Works great - like having a new computer! March 27, 2016 I purchased a 2TB WD Black HDD to replace the 500GB drive in my mid-2011 iMac that was almost at capacity. The new drive has 4X the space, 4X the cache size and spins at 7200 RPM vs 5400. The difference is astounding - it's almost like having a new computer! Opening the iMac was challenging but it didn't take that long. I had my 11 year old son hold the display so I didn't have to remove the main display cable (which I heard was a real pain to remove / replace) - I only had to remove the 2 cables on the left side of the display, was able to get at the old drive, remove and replace. This is an EXCELLENT product and works as advertised.

    Rating: 5/5 Exactly as advertised March 25, 2016 With a little trepidation, I decided to replace the OEM hard drive on a mid 2011 21.5" iMac and replace it with a 480G SSD from OWC. I watched the installation video a couple times to get myself oriented before actually doing the work. The video was perfect. The supplied tools worked well. I did not have issues with the suction cups as others have noted. From start to finish was just under an hour--I was in no rush. The hardest part was reconnecting the smallest cables. I would recommend this to my friends. For a couple hundred bucks (this kit and SSD), the life of the machine has been extended and the speed difference booting and opening programs is phenomenal.

    Rating: 5/5 Saved some money w/ this January 30, 2016 Got a quote from a local Mac reseller to install an SSD in my 2011 27" iMac, which was way more than I'd expected, so decided to embark on this installation myself. Honestly, the parts probably don't equal the cost, and you could likely find all the pieces separately for cheaper overall. However, the convenience of having everything I needed in one package, combined w/ the overall savings compared to the local reseller's quote, made this so very, very worth it. The installation video was extremely helpful as well! Definitely recommend.

    Rating: 5/5 Excellent value January 24, 2016 So, I've finally bitten the bullet and opened my iMac to get that SSD upgrade in place. This kit, and above anything else, the video, made all the difference in the world. Really good stuff.

    Taking apart the iMac wasn't all that hard, considering, and I'd might even try it without the tools in this package now that I know how but why take the risk?

    Rating: 4/5 Ensure you have the right tools for the job November 30, 2015 This tool kit was helpful to ensure you can handle the unique screws and the like inside your Apple products. The tools are of decent enough quality and the case helps to keep them together nicely.

    The only concern I have is regarding the suction cups. They state they are a heavy duty model, but they just didn't hold when pulling the glass away from the iMac. One would lose grip and the glass would twist. I don't trust them and wouldn't use them to lift the glass. They did provide a good grip, but just were not the quality I expected.

    The kit is great quality all around, I am delighted that I bought from OWC. The in-line thermal cable is an ABSOLUTE must. DO NOT go with an SMC fan control solution. This is a hardware solution and work precisely as advertised. Easy to install once you are inside the mac.
