OWC SSD Upgrade Bundle for 2012-2019 21.5" iMacs, Mercury Electra 1.0TB 6G SSD, Express 2.5" USB 3.0 HDD Enclosure, Installation Tools and iMac Screen Adhesive Tape Set

Found the kit after I was looking at doing either an upgrade or replacing my 2017 Mac as the beachball was coming along more and more often. With the move to a 500gb SSD in this kit, no more beachball, and instant start up from power up - I used to have to power up my Mac and wait around 5-10 minutes to get it all loaded and ready to go. Now it is up and ready within 15-30 seconds. There are no slow downs and it feels like I bought a brand new machine.I am a techie, so the install was fairly straight forward, but if you decide to take it on yourself, make sure you follow the instructions to the letter. All of the supplied materials were perfect, the adhesive strips were ideal and the whole piece of work was incredibly smooth. Again, I have worked in technology all my career, so this was not daunting at all, but for non-techies, this might be a little tougher.One other point, I only went for 500gb as I keep most data in the cloud and do not do video editing, so the space I needed was not great, I still have plenty of space having got everything installed again.If you have an older Mac such as mine, this is well worth the effort and will most likely extend your Mac's life by several years. Its a really good package, and highly recommended, as it was far far cheaper than replacing my Mac!

Replaced the spin drive in my 2019 iMac with this. There were no problems with actual installation*, formatting, or operation so far. Dramatically increased the responsiveness of my iMac.*Of course, I mean once you breach all of the hurdles Apple puts in your way to discourage upgrading at home. (Helpful Hint: Use a hair dryer or heat gun to completely soften the adhesive holding the screen on. It may appear to be coming loose…right before the glass fractures. The glass cannot be replaced, you have to buy the entire display assembly. Thank Apple.)

My late-2012 21.5" iMac slowed down, then slowed down even more - to the point where closing one program and opening another took 3 minutes or more. All indications were that the iMac's hard drive was dying. I started pricing out new iMacs and was looking at spending around $1200 when I realized I could replace the hard drive myself for $149. I figured that in the worst case scenario, if I screwed up the installation, I would still have a 1TB external drive for my new computer, thanks to the external case included in this kit. I watched the Other World Computing (OWC) video on YouTube a couple of times to familiarize myself with the steps involved. Swapping the hard drives went very smoothly, and took about 30 minutes to complete. I recommend taking your time and working at a slow, careful pace. After the install I started my iMac while holding down Command-R, followed the prompts, formatted the new drive, and then recovered everything on the old drive from Time Machine. The Time Machine recovery took about eight hours. When it was finished, I was amazed at how fast my iMac operated. I'm very happy with this product, the new life it gave my iMac and the significant amount of money it saved me!

Works well, and delivers what was promised

I did this first time ever and it was complete success. Everything required provided.

The install was easier than expected. The Tool in the kit for separating the screen from the PC was more than worth the extra money. The install was very straight forward. I went to boot up after the install and got hung up on finding the SSD drive. It was my fault and forgot to format the SSD. Luckily the customer service was 1 call away.... I called and was on the phone with someone in less than 3 minutes..... They help me format the SSD and now the computer is running like its never had. I never thought this would make that much of a difference.... Very Happy!

Late 2013 iMac:Easy install. Follow the directions in the video.When you disconnect/reconnect the display cables, just be a little careful - don't pull the cable from the first socket. Use the notch on the sides to release it.Took me <1 hour for the install.I had the OS installer on a USB 3.0 stick (Mac OS Journaled file system) - This doesn't have to be in APFS format.I recommend using a 3.0 stick. Using a 2.0 Stick will be slow.After the disk change - boot the machine pressing the "option" key.Using disk utility, format your new SSD with the APFS file system option - When done, close the disk utility. It will take you to the install screen. Install the OS and then complete the WiFi setup/icloud and other privacy/analytics option.Interestingly, the OS install didn't take much time. I thought it would take 40-60 min. But it felt like it only took ~15 min- I think it is probably because of the 3.0 stick.I did a fresh install - no time machine restore.It felt like the whole process took less than one hour - HDD swap + OS install. That simple.Computer feels brand new now - remarkable difference in speed!-I read a customer's comment about the Microphone getting blocked - don't know why, unless the adhesive that they sent was a larger size by mistake. Well, if it feels bigger than what they show in the video, just cut it with a pair of scissors. No big deal. I didn't have that issue.

This kit included all required components to open up that computer and replace low performance Hard Drive. It's given my 2017 iMac a new lease of life - and saves spending thousands on a new iMac.

Justo lo que se necesita, las juntas con pegamento quedan exactas y muy bien explicadoEl disco SSD jaló sin ningún problema

Pour le remplacement d'un DD par un SSD ;facile à opérer, résultat parfait comme attendu

Totally transformed my imac. Rapid!

I was ready to scrap my 2017 iMac. It was so slow as to be unusable. I had no idea of the improvement in performance this SSD HD would deliver. Now I’m editing 4K video for the fist time! Very happy!
