OWC 1TB SSD Upgrade Bundle For 2011 iMacs, OWC Mercury Electra 1.0TB 6G SSD, AdaptaDrive 2.5 to 3.5 Drive Converter Bracket, In-line Digital Thermal Sensor Cable, Installation tools

Great deal - did just what it was supposed to do. A1+++

My 2011 iMac was grinding to a halt. Booting up and logging in took 5 minutes each time. I looked at the price of a new iMac and decided for what I use it for, mainly emails and browsing the web, it just wasn't worth spending the best part of £2k plus I like the fact I still have a CDRom drive. After a bit of research I stumbled on this upgrade and thought I'd give it a go. Plenty of videos online to show you how to do it. From my experience, I would recommend you get a head torch just to make is easy to see inside when you are disconnecting the cables. I would also get a can of compress air to clean up 10 years worth of dust which had built up. The replacement of the drive was fairly straight forward, took about 25 minutes (1st time). Having booted the new disk and saved the boot image from a USB, the initial problems arose when I attempted to restore from the TimeMachine backup. I have been running the TimeMachine on an external WDMyCloud NAS drive. No mater what I tried, I was getting all types of permision issues. I ended up putting the old drive back in and making another backup to the WDMyCloud, checking all permissions were correct. Put the new disk back in, still unable to restore. After several more frustrating hours and much research, I discovered that you will never be able to restore the TimeMachine backup from a NAS system, despite what WD may tell you. Its fine for individual files, not for complete restores. Put the old disk back in and backed up to a standard external drive. Put the new disk back in again (its now only taking me 10 minutes to do a complete disk swap) and this time I could see and restore the entire system form the TimeMachine backup. The only other issue I have, is I lost the license key for my Microsoft Office 2016 package and have been unable to retrieve it (I think I had bought the copy from ebay years ago so not really a surprise it no longer works). A check on the speed of the new disk shows 6.5 times increase in performance. Boot up / login takes 30 seconds, amazing really. If I get another few years out of this system, I will be very happy. In a nutshell, advice to others looking to do this upgrade, as long as you can hold a screwdriver, don't be afraid. Make sure you have a full backup using timemachine before you start, and make sure its not on a NAS drive. Make sure you create a bootable image, probably best onto a USB. Make a note of any licence keys. If you use Apple Numbers, make sure you have a copy as you can no longer get a copy from the app store if you are running OS High Sierra, which I assume you will be. Hope this helps.

This kit (and the online videos) made the SSD replacement in my 2011 iMac very easy. Everything was presented clearly, and it took very little time replacing my hard drive. But be careful! Unfortunately I ruined my iMac after the replacement was finished, and I was in the process of closing the computer back up. When it came time to reattach the monitor's data cable, I guess I didn't have it lined-up properly and was using too much force and broke the connector/end of the cable. Luckily Amazon sells replacement cables for only $12. But when that arrived, the same thing happened. Ordered another cable, which seemed to go in fine, but the screen was still blank. I think I must have damaged the actual plug (on the motherboard) during that first attempt. Turns out I'm not alone. A lot of people have trouble with that particular plug. The other plugs are easier to manage. But all of that isn't the fault of this kit. It's just awkward with that cable because it's kinda dark, hard to see, and you are balancing the screen with one hand while trying to plug the cable back in. Just be real careful when it comes to that cable. Maybe watch a few YouTube videos about it before attempting? HINT: If the OWC website is down (like it was when I was doing the upgrade), you can find their installation videos on YouTube.

This has uplifted my 2011 iMac to almost like-new performance. This included all the parts and tools I needed. I separately bought a $10 ssd enclosure to do the initial copy although you may copy several ways. The instructional video is very detailed and having never opened my iMac, I felt very comfortable performing the upgrade. I highly recommend this kit and while you may save a few dollars buying the parts separately, I found this to be a great value for price and quality. I have used OWC products before and they continue to deliver.

Great upgrade to my ‘obsolete’ 2011 iMac 27” with 1TB HDD. Now boots up much faster, no longer randomly crashes and has given old machine new lease of life! Just take care when refitting delicate cables (especially LCD display) as I mangled mine and had to replace. Also, had some difficulty cloning old drive which was made more difficult as I had a Bootcamp partition (no fault of the product, but useful to know). Well worth the effort though, if you are considering doing it. I also ended up buying an external USB HDD drive adaptor to help cloning process. The bonus is I can now use any old internal HDD drive plugged into a USB socket.
