## Questions & Answers

**Q: Is it compatible with sata 3?**
A: I have a 2012 non-retina MBP & repaired it with this kit. It is a 6 gigabit connection on the machine (sata 3) and it's worked flawlessly since. Put in a 1TB SSD & it's like a new machine again.

**Q: Is this a data cable that fixes the widespread issue with original cable failure? How can I tell if I need the bracket? Some cables don’t include that**
A: I have ordered two of these for different Macbooks, both came with brackets and worked 100% - I will certainly order again form them if needed!

**Q: I recently upgraded my mac mid 2012 with a owc 1tb ssd, the factory cable has trouble reading it certain dash’s. will this cable work?**
A: My 2012 Pro couldn't see a ssd...and I tried several.  After a lot of looking online, it seems this is a common problem with the 2012 model due to thin insulation on the cable plus a slightly rough finish on the inner housing the cable passes over.  I laid down a few pieces of electrical tape on the inner housing where the cable contacts the housing and changed to this cable...  That seemed to do the trick.  I haven't had any problems since.  Hope this helps.

**Q: Is this compatible with a mid 2013 macbook air 13”?**
A: No. It is not.

### ⭐⭐⭐⭐⭐ Fix For Sudden Slow SSD Read / Write Speed
*by M***. on January 21, 2020*

I purchased a 1TB Samsung QVO SSD for my MacBook Pro A1278 Mid-2012. Computer was running smoothly for about a month or so, then one day after waking up my computer from sleep (as I never turn it off) I noticed I would get random slow downs for little-to-no processing activity. Ran disk utility, fresh OS install, nothing worked. Strangely enough when I plugged back in my 7200rpm HDD internally it ran BETTER than the SSD. I would also get no slowdown when I would plug the SSD to a USB enclosure and booted from there.Did some Apple Support forum searching, and found that the issue was either because TRIM was turned off, or the internal HDD cable went bad and cannot keep up the read & write speed of the new SSD. After enabling TRIM and no noticeable change, I purchased this as a last ditch effort before calling the SSD a lemon.Install took about 5 minutes. The included screwdrivers worked well. After connecting and booting I am back to normal! I wish I would have bought this before wiping my drive. The only reason why I didn't buy sooner was that I am diligent with HD backups, so I didn't lose anything for trying before buying.Definitely recommend purchasing and installing from the beginning if thinking of upgrading to SSD. With the cable being relatively inexpensive and easy to install, it's worth the swap while conducting the upgrade itself to avoid potential issues down the road.

### ⭐⭐⭐⭐⭐ Working perfectly
*by C***S on April 1, 2024*

My brother's 13-inch mid-2012 MacBook Pro was exhibiting extremely long boot times, slow & failing file copying, and long periods of beach-balling. I was fortunate to have the same laptop myself to troubleshoot with. After swapping RAM, the hard drive, and the hard drive ribbon cable, I concluded that the cable was the problem. I later learned this is a fairly common issue with these MacBook Pros.I left my working ribbon cable in my brother's laptop so he could take it home. I then purchased this cable to replace the failing one. Although I didn't use them (I have my own took kit), this kit provides screw drivers and spudgers to access and replace the ribbon cable. I appreciate the reinforcement eyelets around the part where the ribbon cable bends and gets screwed to the motherboard. This bit of additional structure gives me better sense of protection around where the screws might have the potential to damage the cable. Replacing the cable only took only about ten minutes and is quite easy. My computer is back to being fully functional. I wouldn't hesitate to buy another one of these cables.

### ⭐⭐⭐⭐⭐ Great Product, Great Price!
*by G***E on September 11, 2019*

I thought my HDD died but later figured out its the cable. I didnt care bc i use my optical bay for an SSD, but decided to finally get this fixed so I can prolong my SSDs lifespan by not writing to it anymore. This product is great and they also include the tools to get the job done! One thing i really appreciated was that the tutorial i watched, the instructor will have you remove the small ribbon by the white piece and replace it, but by buying this product they already included a new part with that assembled already so that made made installation quicker and easier. I finally have 2 drives in my 2012 mbp again. Thanks!
