Review: Fixed the issue of not being able to install OS (MBP 2012) - My 2012 Macbook Pro was recognizing the hard drive (actually an SSD) Yet something was flaky. It took forever to seemingly install Mac OS but then would not correctly boot as it did not complete the install. I tried this twice. I suspected the cause was a flaky HDD cable, not at all uncommon in some Macbook Pro's as the bottom case can press down and affect the internal HDD cable on occasion which can cause similar issues as described. So I ordered this HD cable as a replacement. I find it easier to get the COMPLETE ASSEMBLY WITH SLEEP BRACKET already attached (this style) I find it worth another 4 bucks as the cable part is tiny to get into the old bracket. I replaced cable with this one. I also reinforced / protected with some black electrical tape covering the cable on top. I was able to install OS, booted up immediately. My hunch about bad cable was correct. I had gotten Sunmall HDD cable before and find it reliable. So recommend. BE SURE YOU GET CORRECT ONE FOR YOUR MODEL/YEAR ! They state that clearly.
Review: I was skeptical - I got a 2012 MacBook Pro that looked pretty good but didn't recognize any hard drive I put in. I could get it to run fine off an external drive but who wants that? By chance I saw a comment somewhere that said the sensor that is also attached to this cable can fail - apparently a common problem with this model. Who knew??? I took a chance and ordered this and damn! so the SSD I had installed and is running like a clock! Happily surprised!

### ⭐⭐⭐⭐⭐ SAVED THE DAY
*by M***A on April 9, 2025*

All of a sudden I started getting the folder with a question mark on my 2012 MacBook Pro 13". I did online research and figured it must be a bad cable. And it was! This saved the day. It wasn't hard to install (many youtube videos explain how). The only thing easier wouldn't been the battery. How I deduced it was the cable (people will always say it's the software): it's a common problem with these computers, for the first 4-5 times it was sporadic when I got the question mark folder, I unscrewed the bottom and pushed the cables down which helped once, and finally I removed the hard drive from the computer--put it in a harddrive holder and connected it to another computer and could access the content on the drive. This was WELL WORTH the cost and I got it much faster than anywhere else. Some places (such as the place I bought the refurbished computer from --OWC--didn't even carry the part. Oh, and I'm typing this on the computer that had the bad ribbon. Thank you Amazon and the company that made this cable/ribbon!
