It worked!!!

Easy way to upgrade my 2015 Macbook Air. Paired it with an M.2 SSD. Easy cheap way to upgrade to 1TB! Just make sure that the sled is fully seated in the slot on your Mac. I also added some kapton tape to the end with the connections so that it doesn't foul with the grounding shield. just a precaution.

If you need a large data storage device, consider this option but be prepared to pay a little more.

Works great, and now I have blazing fast speeds on my 2015 MBA. I have a Firecuda 530 1 tb NVME ssd in it right now, which is way overkill, but it’s all I had. Once I get a pcie 3.0 x4 stick I’ll swap it out, and shouldn’t see any performance difference. Even so, getting well over 1,000 MB/s read/write on my MBA is like 10x faster.If you’re looking to upgrade a Mac and have a pcie slot to use (some SSD’s are soldered to the board), get yourself an NVME SSD M.2 drive before upgrading your RAM or CPU (if you even can). It will make the biggest impact on performance upgrade. Then upgrade RAM 2nd, and CPU 3rd. I didn’t upgrade my CPU because the next model up wasn’t much of a performance increase for the price.I recommend the Crucial P2 NVME SSD in either 1TB or 2TB for the price conscious. For a bit more $ you can’t go wrong with the Samsung 970 EVO Plus 1TB or 2TB. I’d recommend a 4TB drive, but the pricing on that size is still too high.

its not compatible at all with MacBook Pro (Retina) 15” A1398 (Mid 2013).It seems, seller, him selves doesn't know what he selling.

I used it to upgrade my 2017 MacBook Air to a Samsung Evo 970 2TB.Drive was a breeze to install into the computer. Booted with a High Sierra USB (10.13) but the drive wasn’t recognized. Tried again with a BigSur USB (11.0). Drive was recognized right away. I formatted it to APFS, clicked install and away it went. ~30 minutes later I was up and running with 2TB of storage and a significant speed increase. Old 256 gig OEM drive ran 465MB/s writes the new Evo 970 drive 1285mb/s writes.I’ve not had any sleep/shutdown issues. For the first day the fans spun up a bit. I’m attributing that to the computer re-cataloging all of the files in spotlight after I migrated the data from my TimeMachine Backup.Definitely recommend this product for upgrading your computer.PS. The listing doesn’t mention this but the adapter if for Single sided NVMEs (ex. Evo 970) only. If you have a double sided NVME you’ll need an adapter without a PCB backing board on it.

Connects and screws in perfectly. As many reviews on the web suggested this is one of the best adaptors for MacBook upgrades. I chose a 1TB Intel 660p SSD to pair with this as I've had many Intel drives and they are built well and firmware is aways compatible. While you could get the much faster Intel 760p SSD for the old 2014 MBP this was fitted to the 660P was fast enough.This adaptor worked without any issues first time and gets the full 4x PCIe if your MacBook supports it. Some older MacBooks have the 4x PCIe connectors but the original SSD doesn't support more than 2x PCIe (ie Mid 2014 MBP). So in many cases you not only get a cheap way to upgrade your storage with the M.2 drives that are common and getting cheaper, you get the bonus of up to twice the speed.The only small issue is that the MacBook connector has a metal grounding tab which is designed to press down on the original drive where there is a large grounding pad. This pad isn't on the adaptor since it needs all the space to fit the newer M.2 connector. This gets the grounding tab extremely close to the tiny wires on the M.2 connectors, if you over insert the adaptor it can short the pins. Since you fit this with the battery unplugged and MacBook off there is little risk during install. Though if the screw came loose or during a fall it may shift the 1/2 mm and short. A small bit of quality electrical tape or similar non-conductive tape over the pins is a quick fix.

***Not an employee, and this is a 100% real post**I had gotten a used Mid 2013 Macbook Air from a friend that had the hard drive fail on them. I looked for a replacement drive that was compatible and saw that they were quit expensive for such a low amount of storage space. I decided that I wasn't going to spend that amount of money on a 6 year old home lab computer for a replacement drive and looked for adapter alternatives. Most adapters I found claimed to they would only support certain brands and model NVMe PCIe drives and I wasn't going to spend the money on those name brands either. I found this adapter that didn't have a single review but claimed it just worked and I purchased it in hope that I could buy a cheaper drive and get the Mac-book up and working for a less then $50.00 US.I purchased this and a Sabrent 256GB Rocket NVMe.https://www.amazon.com/gp/product/B07KGLN3HN/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1Got me in under my budget and works great. The packaging was excellent, it arrived via Amazon Prime 2 day shipping and came with screws and a separation nut which allows for the drive and adapter to have air flow. Very happen with this combination purchase and would recommend to anyone.

This product is a great value. I had already purchased a regular M.2 drive from kingston and didn't want to have to pay for another drive (that would have been twice the price).IF YOU HAVE AN OLDER MAC THAT DID NOT COME WITH macOS High Sierra YOU CANNOT FOLLOW THE REGULAR INSTRUCTIONS TO INSTALL IT!!!But I figured out another way.So be ready to do some putsy things and jump through a few hoops.to make it work. The following instructions are how I got it to work on my machine (Macbook Pro 12,1, Early 2015). I'm sorry if it doesn't work for you.Oh, by the way, doing this voids your warrantee, so if you still have warrantee and you care about keeping it, don't do this.0. Install the hard drive in your mac following iFixit instructions and the instructions that come with the adapter.1. If you have a recent Time machine backup you can skip to step 4.2. Update your system to the latest version of macOS.3. Make a time machine backup of it.4. shut down your system and connect whatever external drive you made the backup on to your mac.5. hold down the option button and press the power key.6. You are now in the bootloader. select the green Time Machine disk icon using the arrow keys and press enter.7. wait awhile for it to boot into recovery mode. This recovery mode is different than the you may have already tried. This one comes from your High Sierra or later version you backed up.8. Click on "Disk utility" and press "continue."9. Make sure that in disk utility it recognizes your disk. Click on it and in the toolbar at the top, click erase. Select "APFS non case sensitive" from the drop down list or something like that and click erase or continue (I can't remember what it is exactly). Give the drive a name like "macOS" and press erase.10. that might take a while. Just be patient.11. Go back to the main menu and click "Install a new copy of macOS" and click "continue."12. Click the installer's continue button and accept the terms of service.13. After formatting, it should recognize your disk now as an internal hard drive. Select it and continue. It'll probably ask you if you're sure and that this will erase the drive. It might also ask you which format you want to use. Choose APFS again if it does that, otherwise click the continue button.14. go through the rest of the screens, putting in whatever other information you deem fit.15. depending on your internet connection, this might take upwards of 4 hours. I left it and went to work. I came back 4 hours later and it seemed frozen. Don't panic. leave it for another few hours. When it stays frozen for an hour, you can do a force shut down by holding the power button for a few seconds.16. detach your external drive and reboot. If it can't figure out to boot into your new macOS installation automatically, select it at the boot loader.17. This first boot up might take a while. Be patient.18. Now it should present you with the "Set up your mac" program. Now you can set up your mac how you want. At this point, you can restore from the time machine back up you made earlier if you so choose.19. Enjoy your increased storage!.I hope you found this helpful and feel free to comment any other problems you encounter.
