    Similar to most reviewers, I too have been plagued with problems

    • Written by Nathan T from Exton

    I bought this with the intent of connecting the USB-C / Thunderbolt end to why 2017 MBP and, along with an OEM thunderbolt 2 cable from Apple (I own a short and a long one, which were expensive when they were the current standard and rarely used AKA: like new) was planning to connect to my 2013 MBP's thunderbolt 2 port. My idea was to bypass wifi/Air Drop for maximum data transfer speeds. Was I successful? Of course not - if I had been, you'd see more stars on my review.

    Each OEM adapter/component cost around $50 when I purchased brand new (around $150 total). No need to detail the cost of the laptops themselves, but suffice to say, I expect my overpriced adapters and cords to work without exception - in a closed technological ecosystem such as the one Apple has created, I don't think this is too much to ask. The sad part is I also have really old and battered 2012 MacBook pro with a single thunderbolt 2 port on it. I was able to connect to that laptop without issue which means that there's either an issue with my MBP2013 thunderbolt port (both of them?) or there's something wrong with the adapter. Maybe there's some compatibility issue with my MBP2013's thunderbolt firmware, but where would I go to find out more info on this? I'm so frustrated by the fact that my 2017 MBP needs dongles and adapters for literally everything I want to do with it, standard functions on older machines, and when I shell out the money, I still have problems.

    Bottom line: Buy yourself a used 2015 MacBook Pro with a standard set of ports, don't buy this awful adapter because it clearly wasn't tested properly, and save yourself time, money, and headaches.

    Useless to connect TB2 Mac to SSD Drives that get power from thunderbolt 3

    • Written by Robert B from Saratoga

    Bought this because it says its bidirectional and should connect a thunderbolt 2 Mac (Late 2015 iMac in my case) to thunderbolt 3 peripherals.

    Unfortunately nowhere on the box or the website does it say it doesn't transmit power between the ports. Most of the SSD drives expect to get power from Thunderbolt 3.

    Now I have to return everything and I can't use a modern SSD Thunderbolt 3 drive on my iMac.

    Apple needs to put this directly in the title of the product, because it's a pretty huge issue. I purchased this because I was using a mini dp display with my old MBP, once I switched to the new one I thought I would just purchase this to make my existing setup work, which was wrong. This will NOT work with mini DP monitors so now it's a useless $50 dongle I can't return

    Works using iMac as a display but no audio passed through

    • Written by Ryan R from Inverurie

    Poor show from Apple. This works ok with an 2012 iMac hooked up as an external display (as long as I'm logged out of that Mac, go figure) but audio cannot be played via the iMac even though it's a output option in theb menu bar.

    • Written by Bert M from Sedona

    i bought this to use a usb 3C drive with 2011 iMac thunderbolt 2 . turns out it doesn't pass power to the drive and is rendered useless. Cant find a powered ssd enclosure. So it looks like usb2 device and is very slow.

    I wanted to connect Evlvr to old 2013 macbook pro 15". It stated it was bi-directional and expected it to work. The SSD does not light up nor connect with the rmbp.

    Buyer beware

    • Written by Terry M from San Francisco

    "As a BIDIRECTIONAL adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port and macOS Sierra"

    Except it doesn't. Not on a late 2015 iMac's thunderbolt 2 port connecting to a LaCie D2 USB C port on MacOS 10.12.6. Must connect using LaCie's USB 3 cable at USB 3 speeds. Buyer beware.

    Works great for use with TB audio interfaces.

    • Written by John M from Lisburn

    I use this to convert a TB2 cable for use with a TB3 port on my Win10 PC and 2018 Mac Mini. No issues. Build quality seems fine. Rated 4 our of 5 instead of 5 solely because it seems a bit overpriced.

    Works with FireWire adapter, not work with Mini DisplayPort to DVI adapter

    • Written by Jasper R from Conway

    I bought it mainly to use with my old FireWire adapter and thankfully it works with my ThunderBolt FireWire adapter, albeit with a few hiccups. I was hoping it would also work with my DVI display. I have tried a few different DVI monitors with this and a Mini DisplayPort to DVI adapter and it does not work at all. I may end up having to get a USB-C to DVI adapter, which Apple does not sell.

    I feel so screwed over.

    • Written by Jeroen H from Amsterdam

    Of all the overpriced Apple cables that I own (and I have A LOT of them), this is the most useless one. It doesn't work if both devices you're trying to connect don't have their own power source. Which means it won't work on most external harddrives. Since that's the only thing I needed it for, I'm feel cheated. There should at least be a big red sticker on the package stating how this thing doesn't provide power. I can't believe I paid 55 euro's for this. I know it's been a long long time since Apple actually cared about its customers. But this a whole new level of disrespecting people. It makes me want to quite Apple products altogether.

    Adapters are garbage and should be pulled/discontinued

    • Written by Erica H from North VANCOUVER

    I have x2 of these, one purchased last week and another purchased a year ago. Neither of these will connect my G-RAID storage device to my mac pro 2013 (Sierra). The USB-C connects it fine to my macbook pro, the USB connects to both computers, but using these adapters to go from USB-C/Thunderbolt 3 to Thunderbolt 2 does not work. Garbage! I decided to purchase a thunderbolt 3 device over a thunderbolt 2 because of the existence of this adapter. Thanks apple!! My loyalty was already waining... I can't keep up the charade any longer. You guys have really abandoned any common sense here.

    2017 iMac + Thunderbolt Display

    • Written by Brynnlee B from Carlisle

    There are WAY too many negative reviews on this adapter --- and most are likely nonsense. Just connected my 2017 iMac (27" Retina) with this adapter directly to my Thunderbolt Display (purchased in 2015). Works FLAWLESSLY! It recognized it, fired right up and there are no issues.

    Stop reading all the negative reviews -- if your set-up is like mine ... This cable will work. Buy it and move on!

    Worked great: Apple Firewire Thunderbolt 2 -> 2017 MBP Thunderbolt 3

    • Written by Mark E from Littleton

    I have a couple of old Sony camcorders that only have Firewire interface for pulling video off of them, and historically I have used an Apple Firewire Thunderbolt 2 "dongle" to accomplish the task. Now that I have a shiny new 2017 MacBook Pro with Thunderbolt 3, aka USB-C, I needed a way to bridge the gap between the old and the new.

    After reading the various reviews, it became apparent that this particular use case should work fine since my need is to go from legacy Thunderbolt 2 to Thunderbolt 3. So I purchased the adapter from the Apple store, plugged everything together, and like magic, Final Cut Pro recognized my old camcorder and pulled video from it just like the old days.

    This is literally the only reason I would use this adapter, but for my purposes it works perfectly. I docked a star from my rating purely because of the crazy cost -- $50 seems like a whole lot of money for a simple dongle. But it is Apple after all.... :-)

    This adapter screwed me bigly.

    • Written by Eric W from Thunder Bay

    Just bought a new LACIE 2Big Dock Thunderbolt 3 for my new MacBook Pro. Now how do I transfer all my data from my old Lacie 5Big Thunder bolt 2 drive when this adapter can't do the job? The description says it can, but it can't! I have two of these adapters and neither work! Did i just lose over a thousand dollars because of this adapter? I'm so screwed!!! What do I do now?

    They do not appear to work on older Macs

    • Written by Don L from La Habra

    Apple's documentation says that this adapter should work in both directions. That is allow a Macintosh equipped with Thunderbolt 2 ports to connect to a hard drive equipped with a Thunderbolt 3 (USB-C) port. I tried this with a new G Drive mobile USB-C drive. It would not work. I tested the drive on the same Mac via the USB 2 port it works (slowly). I test the computer's Thunderbolt 2 ports with a native Thunderbolt 2 drive. This combination work also. That leaves the 'Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter' as the failing part. I contact Apple support. After about 30 minutes of texting and testing, they recommend I return the adapter as defective. However. I actually had a second adapter I wanted to connect two new hard drives to this computer. I tested the second adapter. The same problem, no connection. It appears that this adapter does not have the level of compatability Apple claims for older Macintoshes with Thunderbolt 2 ports.

    Works as Advertised

    • Written by Guinevere M from Teague

    I was really concerned when I read all of the negative reviews of this product, but I needed it to make my old external drives work with my new MacBook Pro as well as to assist with transferring all of my files from the old MacBook Pro to the new one. This adapter worked perfectly for me. I had no trouble connecting my 2018 15" MacBook Pro to my old MacBook Pro to transfer my files. Furthermore, it works great for me to connect to my external hard drives, which are still running with Firewire 800, an adapter that converts that to a 2nd gen Thunderbolt cable, which was then plugged into this adapter. No problem with the drive mounting and being read or writing to it. This system (albeit a bit on the convoluted, too many dongles side) worked fine with external drives that have a separate power source as well as external drives (such as a LaCie Rugged Drive) that are powered through the Mac. Between the purchase of this adapter and a $40 hub, I am good to go with my new computer and my old peripherals.

    ONLY works for TB2 Connections

    • Written by Tim H from Woodinville

    Note that this adapter ONLY provides a Thunderbolt 2 connection. It does NOT duplicate the DisplayPort features of Thunderbolt 2 connectors on earlier Apple laptops, so you CANNOT use it to connect display.

    Didn't work even though Apple support says everything is the correct setup.

    • Written by Kirsten G from Philadelphia

    Very frustrated. I have been using my 2011 iMac as a backup to my mid-2015 MBP as well as a secondary monitor for a couple of years. Purchased a brand new 2018 13" MBP with touchbar. Bought this expensive adapter to continue to run the iMac as a secondary monitor. IT DOESN'T WORK. Spent 30min on the phone with support who confirmed it should work (set up was correct). All I get is a black screen (my MBP recognizes a second display in settings but nothing but black on the iMac). I absolutely need a second screen for work. I have spent way to much time searching support, googling, and now researching new monitors. Thanks Apple.

    I guess I should have heeded the other reviews that said this thing does not work. Indeed it does not. I bought this to connect a usb-c external drive to my iMac's thunderbolt port but the drive wont mount. Drive works with the usb-c to usb cable.
