Rating: 5/5 Hard drive 'failing'? Maybe, maybe not...... January 17, 2019 Hi Fellow MBP fans! I have an early 2011 Macbook Pro (MBP), 13". Through the system status pages found under the apple menu I discovered that the hard drive was listed as "failing". Okay, sounds reasonable the computer was running slow and would occasionally quit, so get a new hard drive. Did some research and decided to go with an SSD and up the space, 1TB. Came across a comment that you should replace the ribbon cable at the same time, but didn't want to just throw parts at the MBP thought I'd try the hard drive first. Mistake. Installed the new hard drive and started the time machine restore. 10 days, yes, 10 days later the time machine restore was complete. I had a couple of failed starts, my fault. First time I was curious what would happen if I removed the charging cable, the battery was showing full charge. The MBP went blank, start time machine restore again! Next time, two days in, I came across the comment that if you started with the time machine back up plugged into your usb port it would transfer data at the slowest rate. I couldn't remember, so I restarted it hoping it would be faster. No, it was not. 3rd time I figured if it was 'working' I'd just let it go and see how long it took. I had also read the time estimates can be "wildly off". Well 10 days later I had a complete time machine restore. Now to use the MBP! Nearly unusable, very slow, wouldn't shut down, pinwheels on every click, very slow restarts, disconnect the power and it went blank, and more. The time machine restore had worked, but obviously there were still problems. Ordered the cable, installed it and yea! Now my MBP is back and faster than ever. I also installed max RAM (16g) since I was in there. Oh btw, I bought an empty hard drive enclosure from OWC as well and put the old hard drive in it, it works! Now I have a spare back-up drive. So, all along I had a bad cable. Always learning!

Rating: 5/5 Perfection March 4, 2018 Was in search of a hard drive comm cable for my 2012 MBP. This site came highly recommended. As soon as it arrived, I was pleasantly surprise to find it came in a proper sized box so as not to bend or fold the new cable. This was a concern as I had found other sites ship the cable folded in half, possibly compromising it from the start. Within a few minutes, I had my Mac back up and running.

Thank you for helping to get my MBP back up and running so quickly!

Rating: 5/5 Try this before HDD replacement!!! March 1, 2018 So I recently put in a new SSD in my MacBook Pro 13' (Mid-2012) and it worked great. However, after about a month, i noticed it starting to slow down. Then it finally couldn't recognize the drive for extended periods of time and when it did boot, it had a large lag. So, I decided to give this a try before buying a new computer. This install is easy and works great. My computer works like new.

Rating: 5/5 fixed macbook pro problem! July 26, 2017 After spending 3 days, tearing my hair out, trying to diagnose the problem with my son's 2012 13" MacBook pro (A 1278 unibody), I stumbled across a forum that said that the original HDD connector was a bad design.

I had been attacking the problem, as if it was a hard drive issue, corrupt OS, resetting PRAM, resetting SMC etc etc etc. I even tried 3 other working hard drives out. One hard drive (a 320 GB HDD booted up every time, whereas, all of the other hard drives and an SSD drive weren't even recognized! Then, after finding the forum where the people identified the problem as being a faulty end on the original ribbon connector, it all made sense. The 320 GB drive had a slightly different design on the connection that made the pins fit tighter on to the connection. When I installed the new ($12) replacement connector from OWC It was a much firmer connection making all of the drives recognized by the laptop.

It is a real shame that Apple didn't bother to notify owners of this model about this defect and/or offer to replace the bad part.

Rating: 5/5 Thank you MacSales.com July 25, 2017 After installing my SSD a month later I get a folder with a question mark in it. I find out its either the Hard drive went bad (Doubt that since it was only a month old or the cable. After chatting with Mac sales. We decide to get the cable. Priced right cable is in NY in 2 days. Replace cable. Boom! All is working properly. Thank You Mac Sales.

Rating: 5/5 OWC saved me over $1000! July 23, 2017 A recent previous order of a replacement internal hard drive for my old MacBook Pro didn't fix the problem. I replaced the hard drive with an OWC SSD and, alas, the old MBP still wouldn't work. I called OWC/MacSales and explained my problem and the representative quickly replied: "Oh, your HD cable is defective." I never would have suspected that. Seems it's a common problem, so common in fact, that OWC sells a replacement cable and for only $15! The final upshot is that this cable saved my MacBook Pro from recycling AND the laptop is running much faster now due to the new SSD. THANK YOU OWC! And thank you for the wonderful installation videos on your web page.

Rating: 5/5 SSD working now! January 30, 2017 I had installed a new SSD into my mid 2012 MBP and was having a hard time getting it to run, I actually went through two SSDs thinking the first one was defective. I went through every troubleshooting step and it still ran very very slow. Purchasing this cable was a last resort to get it to run and it worked! My computer is now faster then it was brand new 5 years ago!!! Thank you MacSales.com for your' amazing customer service. I will definitely be purchasing through you in the future.
