    This adapter screwed me bigly.

    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

    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

    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

    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.

    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.

    Works like a champ....

    Seeing a lot of negative reviews. It is one direction. Your main device must have USB-C port. It will not work if you are going reverse with a Thunderbolt 2 cable to the adapter and then to USB-C external drive.

    It works as intended with my G-Tech ev All-Terrain Case with Thunderbolt. I attach the USB-C end to my latest Macbook Pro and then attach the other end to my external drive. It powers it up and i am able to mount it.

    Worked like a champ

    I saw all the reviews saying the adapter didn't work, and I was leery about buying it. I went to the Apple store, took my laptop(MBP 2014), and my Lacie 6TB Thunderbolt 3 hard drive, and setup the config with the adapter. I plugged the Thunderbolt 3 male end into the Lacie drive, plugged Thunderbolt 2 cable to the female end of adapter and to my laptop. Drive appeared on my MBP within seconds. Data transfer is flowing much faster now :) I'd post a pic of the setup, but I don't see that option.

    Works for data connection to Promise Pegasus R4

    I used this adapter to successfully connect my new 27" iMac (usb-c) to my Promise Pegasus R4 (thunderbolt 2). I upgraded the R4 with new drives, but not using them as a RAID array. On startup each of the external R4 drives shows up on Finder and works as expected. Incidentally, I also daisy-chained another G-Technology 4TB external drive into the open Pegasus Thunderbolt 2 port and it too showed up on Finder without any issues going through this adapter.

    I rate this as 4 stars.. it's a little pricey for 5 stars, folks.

    Only works one way :(

    Older devices -> 2018 Macbook Pro = ok
    Newer (usb-c) devices -> 2013 Mac Pro = nope!

    Maybe this works fine connecting thunderbolt 2 devices to a new macbook pro. But if you were wanting to use it to connect new devices to a computer with legacy ports (re: any computer other than the newest macbook pros) than you're SOL.

    $50 spent, and I still can't connect a usb-c hard drive to my Mac Pro tower.

    Worthless! A Waste!

    Apple might have hundreds of billions saved up...but they are not investing in keeping products useful. I bought one of these worthless devices. Worthless? Well, how do you connect a USB-C drive to an older MacBook Pro with Thunderport-2 outlets? With this very adapter of course. EXCEPT...it will NOT pass any power to the device! A total brick! Useless! What is the use in selling it, except to fleece us! What was Apple thinking we would use these for--decoration! Very, very very, very disappointing. The modern management, it seems, is becoming more greedy, and less helpful as time passes. Beautiful headquarters? Yes, but it won't help me use my hardware, or even retrieve data! They seem to be spending more time on fluff, and less on meat. Like more powerful computers, and peripherals that work. I would give it ZERO if it were possible.

    Works Great with Apple Thunderbolt Display to 2016 MacBook Pro w/USB-C

    Look carefully at negative reviews. If you are an Apple user, using Apple products, such as Thunderbolt Display to a 2016 MacBook Pro with USB-C ports, this works perfectly.

    Most useless dongle ever; don't waste your money

    I have yet to make it work with any external display no matter what combination of cables/adapters I try. This is a useless product. Don't waste your money.

    Complete garbage

    Will not purchase another apple product again. The dongle joke was funny at first but now I am infuriated!

    Has been working perfectly for nearly a year, 100% satisfied

    I have a 2017 macbook pro 13" no Touch Bar and use this adaptor for my Thunderbolt Display. Works just as well as it did on my air with absolutely no faults, and has been every since July, 2017 when I bought it along with my new pro.

    I use the three USB ports and the ethernet port on the back of the display constantly to 100% satisfaction, though I have never used it to daisy chain multiple displays.

    No ability to support Display Port

    It's documented, but so sad. I have a $1000 display that is rendered useless by Apple.

    I have a new MacBook Pro that is only USB-C. The only reason I've done this is because nobody makes new Thunderbolt 2 external drives at a reasonable cost any more, and I need a new external drive, so I figured I'd deal with only USB-C. So then I purchased this adapter.

    This is turning into a major headache. This adapter does not work. My external hard drive won't connect and my external monitor won't connect. I didn't have these issues on my older MacBooks. I'm thinking of just returning this MacBook and getting a windows machine at this point. This new MBP has been nothing but a pain to deal with since they removed all connectivity that people actually use.

    It doesn't work with Samsung's 4K display

    4K display that worked fine with a Thunderbolt (to DisplayPort) port on a 2013 Macbook DOES NOT WORK AT ALL with this Thunderbolt adapter. No signal, nothing.

    Now I have an expensive dongle, an expensive monitor and an expensive laptop — all useless. Thanks, Apple.
