### ⭐⭐⭐⭐⭐ 







  
  
    High quality cable and the bracket makes installation easier!
  

*by K***A on Reviewed in the United Kingdom on 15 February 2019*

I normally don’t write product reviews, but I am hoping this will help someone out there! I was hesitant to buy this, but I had nothing to fear! I decided to upgrade the HDD to an SSD on my trusted 2012 MacBook Pro. Little did I know that my SATA cable was already toast, and even though it was working with the HDD, it could not cope with the SSD. Hours of reformatting, cloning and uncloning, resetting PRAM etc did not help. What helped was this SATA cable! Very easy to install, and the bracket makes you by pass the most fiddly bit of installation. I was also impressed by the quality of the tool that were included! The screwdriver is definitely high quality. Just follow the instructions on You tube, put some insulating tape on the metal body to make the cable last longer. It’s early days, but I am happy. Hopefully the cable is of high enough quality and it lasts a long time. Go for it!

    Perfect fix for MacBook that will boot from HDD but doesn't recognise SSD
  

*by M***N on Reviewed in the United Kingdom on 22 April 2019*

I bought a secondhand MacBook Pro 2012 13" to replace my recently dead 2011. It was good deal but needed an SSD and a RAM upgrade to bring it up to speed. RAM installed I set about trying to install a new SSD. The SSD would format fine in an external caddy but every time installed it into my new MacBook and I tried to install Mac OS via  a bootable USB stick, the MacBook would either not recognise the SSD or if I did manage to get it to be recognised , the install either failed or the one time I did get it to install, it wouldn't start and instead gave 'flashing folder' (is not found) errors.The weird thing was that every time I put the original mechanical HDD back in, the MacBook would start fine.After much confusion, frustration and googling, I fould that a lot of other people had similar problems with 2012 MacBooks. Seems the SATA cable that connects the drive to the logic board can fail over time or even if it works with a HDD, is unable to deal with the increased throughput from a faster SSD.So with nothing to loose, I bought this kit.After a 10 minute install, I was up and running, SSD recognised and was installing Mac OS.Install successful and new MacBook living up to its fully potential. Man it's amazing how slow a mechanical drive is once you're used to SSD!! So glad to get this sorted. Great life saving, reasonably priced bit of kit!

    as expected but the sensor wasn't properly glued
  

*by B***Y on Reviewed in the United Kingdom on 23 March 2020*

Hard to find the root cause of a Mac problem when it seems that the hard drive is the failure. But found in some forums that the cable was the main problem. Replaced the cable and everything went back to normal.The cable is as described. I got the one with the sensor already installed with the bracket but the sensor was not placed correctly. This is a critical part because if this breaks then the cable will not work. Had to push it gentle to its place and very careful not to break it or move it (see picture attached).It would have been nice to get the installation instructions or a link to a video tutorial but it was easy to find one online and it is a very straight forward process.
