Product Description

Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter (Gray)
Apple’s Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter (Gray) lets you connect a USB-C device with a Thunderbolt 2 port. The USB-C connector delivers up to 20 Gbps of bandwidth for data, audio, and video, while the Thunderbolt 2 port lets you connect any Thunderbolt 2 device. When it comes to devices, Apple is known for its innovation, but it’s the accessories that really take it to another level. Apple’s Thunderbolt 3 to Thunderbolt 2 adapter is one of those accessories, and it’s made even better by the fact that it’s made by Apple. Thunderbolt 3 is the latest generation of Apple’s Thunderbolt protocol, which is used to connect peripherals to the Mac computer, and it’s fast, capable, and user-friendly. The Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter is Thunderbolt 3-compatible, so you can connect new Thunderbolt 3 devices to your 2015 and newer Mac—and it’s backwards compatible, so you can use it with earlier Mac models as well.

Facts About Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter

Can this be used to connect a 27″ 2012 imac to a 2017 macbook pro as a second display? please!

It works for me. I I have a late 27-inch 2012 iMac (with the thin edge) and I use it as a second display for my 2016 15-inch Touch bar Macbook Pro. You need this adapter (Thunderbolt 3 (Usb-C) To Thunderbolt 2 Adapter) and an Apple Thunderbolt 2 Cable (0.5 meter or 2.0 meter). You can probably use off-brand cables too … It works for me.

Is the male end Thunderbolt 3 or Thunderbolt 2? Thanks!

The male end is Thunderbolt 3, and the female end is Thunderbolt 2. I used this adapter and a previously owned Thunderbolt cable to connect a 2014 MacBook Air to a 2017 iMac for file transfer.

Does this connector allow you to attach a new battery,backup drive,or other new components that use usb-c port/tec or just with apple product?

You can connect a hard drive that has a thunderbolt 2 port

Is this backward compatible to Thunderbolt 1 port as in MacAir mid 2011??

I purchased this adapter to connect a computer with Thunderbolt 2 (2013 Mac Pro) to a Thunderbolt 3 device. This connection does work for my situation (I needed to get a Thunderbolt cable with male connectors on both ends to complete my connections) and I believe that it will work for your situation since all documenta… I purchased this adapter to connect a computer with Thunderbolt 2 (2013 Mac Pro) to a Thunderbolt 3 device. This connection does work for my situation (I needed to get a Thunderbolt cable with male connectors on both ends to complete my connections) and I believe that it will work for your situation since all documentation that I see says that Thunderbolt 1 and Thunderbolt 2 are the same connectors and are compatible with each other. I certainly cannot guarantee you that it will work but I feel pretty confident that it will.

Does anyone know of a longer such cable from anyone?

I believe this is the only such cable available from any supplier.

Can i connect late 2015 imac 27” to a 2019 macbook pro 16”? i want the contents of the imac screen to be on the macbook pro.

Pretty sure “target display mode” (I.e. cable connection mode not airplay) only works on the iMac side of things. Target disc mode will definitely work.

Can i use this to connect my new imac (thunderbolt 3) to my old imac (thunderbolt 2) to use migration assistant to transfer all my files?

You should be able to, yes. I used it to transfer files from a 2014 MacBook Air to a 2017 iMac.

Can i use this to connect a thunderbolt 2 g-technology hhd to a usb-c 2018 macmini?

I do not see why that particular connection would not work. I suppose it would depend on what you plan to do.

I suppose it would depend on what you plan to do. If you want to transfer files from an iPad or an iPhone, you will need a cable with two male Thunderbolt ends. Otherwise, you may need a thunderbolt adapter to plug into the iPad/iPhone that converts to a female USB connector. Then, you could use a typical iPhone or iPad cable. I have used the adapter to projector from an iPad through a Mac Mini that was connected to the projector, when I did not have a mini-display adapter.

Info About Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter (Reviews From Amazon)

Hideously Expensive. It Also Works Great. But Make Sure You Need It Before Purchasing!

I have an expensive portable Western Digital RAID drive (see it at  WD 2TB My Passport Pro Portable External Hard Drive – Thunderbolt – WDBRMP0020DBK-NESN ) that uses a Thunderbolt 2 connection. When the new MacBook Pro 13 inch models came out, they had nothing but USB-C ports (running Thunderbolt 3: confused yet?). So, my portable RAID drive instantly became useless, because there was no way to connect that existing drive to the new MacBook Pro.

This situation may never be a problem for you, unless you, like me, are attempting to connect a Thunderbolt 2 drive to one of the new Thunderbolt 3/USB 3 ports like those found on the new MacBookPros. But if you are, you’ll need this adapter, which facilitates such a connection. It’s one of the few of its type on the market, but if you need it, you NEED it. It is well-built, and I’ve had no trouble with it on multiple Thunderbolt 2 drives I have been using. It’s physically larger than most dongle-style connectors, with a large, rounded plastic body on one end, undoubtedly where the circuitry and microchips reside to perform the data stream conversion between Thunderbolt 2 and 3. (It also very likely accounts for the high price of the connector, because of the requirement to use controller chips to make the Thunderbolt 2 to Thunderbolt 3 connection possible).

So, I recommend it highly because it works so well, and is built with very high quality. But it is quite expensive. However, if you need it, I would go with this model than some third-party brand that might show up, because Thunderbolt (either 2 or 3) is a modern, high-speed transfer format, and you want to ensure maximum transfer speed with uncorrupted data transfer.

Note:
This entire subject discussion becomes even more complicated because, with the “old” Thunderbolt 2 standard, the physical plug is exactly the same as the “Mini Display Port” connector type. Who dreamed up that bright idea? One (Thunderbolt) transfers DATA AND VIDEO, and the other (MiniDisplayPort), VIDEO ONLY, but they are physically exactly the same! Now, to confuse us further, throw in Thunderbolt 3, and a simultaneous upgrade to USB in the form of USB 3, followed by the decision to make USB 3 and Thunderbolt 3 intra-compatible, you’re sitting there, scratching your head sometimes. Do a web search for C|Net’s Article on Thunderbolt 3 and USB 3, and they lay it out in all it’s intertwined (no pun intended) glory. But, in spite of all the ways you can get confused, if you have a true Thunderbolt 3 connection with a Thunderbolt 3 drive, wow, is it fast (shockingly, up to 40 Gbps). This is the future of connections, so be ready for it. But the thing to note is that USB 3 is a description of a PHYSICAL CONNECTOR. That USB 3 connector might be running Thunderbolt 2, Thunderbolt 3, DisplayPort, and/or USB 3.1 (!). Thunderbolt, DisplayPort, USB 3.1, etc. are examples of PROTOCOLS, and each can run on the physical connector USB 3, but you have to determine what protocol your device and computer support whenever you are using USB 3. The cable may physically fit, but the devices on both ends (plus the cable itself) must all support the same protocol for them to work. Whew.

Solid Solution for Computers with TB2 Ports

This TB3 > TB2 adapter is bidirectional, unlike most others here on Amazon. This means that it can be used to connect TB3 devices to an older computer with only a TB2 port, such as my 2013 Macbook Pro (as well as connect TB2 devices to a computer with a TB3 port). Works like a charm! Solid Apple quality, and the price is very reasonable compared to other similar adapters.

Works perfectly in ‘reverse’ mode with OWC device

When I first hooked this up it didn’t work at all, but that was due to my use of the wrong type of SSD. With the right type it works flawlessly.

My challenge was to connect an OWC Express 4M2 enclosure with four M.2 SSDs to my MacBook Pro Retina 15-inch, Mid 2015. The OWC stated unequivocally that this combination would work: “The OWC Express 4M2 is fully backward compatible with Thunderbolt and Thunderbolt 2….Add a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter along with the appropriate Thunderbolt cable, and you’re all set.” So, despite all the one-star pans by other reviewers I put my faith in OWC.

I purchased four Crucial 1TB SSDs, installed them in the 4M2, and plugged the Thunderbolt Adapter into the enclosure. I connected the computer to the adapter with a Thunderbolt 2 cable. I fired it up, and….nothing. The drives did not show up in the Finder, SoftRAID, or Disk Utility. I contacted OWC support and learned that the 4M2 is designed for NVMe and not SATA drives. I exchanged the Crucial drives for Samsung 970 EVO SSDs (about 50% more expensive but many times faster). The moment I fired it up with the proper SSDs it worked immediately.

The bottom line is that in the right situations this adapter does work properly. If you find it’s not working it might be due to a compatibility issue with other components in your configuration.

Essential for 2018 MacBook Pro

I have a ton of Thunderbolt 2 RAIDs and other older Thunderbolt peripherals. This is essential for me and works great.

Works with external drives

Hi, It’s important to know that these modern cable and connector schemes have small IC’s or integrated circuits, embedded in them to do their hi speed magic. Buying from vendors that are fully licensed and development partners is the way to go despite the extra cost. Apple and Intel have worked hand in hand on the Thunderbolt tech which Intel developed. Despite some bad reviews from folks who may not know what they are doing, or are perhaps using cheaper no name devices, this adapter works perfectly for me. I have drive chassis with a thunderbolt 2 interface that came from the G drive company, a hi end hard drive manufacturer. I installed an SSD drive in it to do fast time machine backups of my Macs for me and clients that I have used for many years. It now works perfectly with my early 2020 13″ MacBook Air. This Apple adapter also works great for my Apple thunderbolt 2 ethernet / RJ-45 adapter and I’m sure it will serve for any other needs. I’ve been an electrical/computer engineer for 40 years now fixing computers to the chip level since the Apple 1…

Does what it’s supposed to. Can’t ask for much more.

It does its job. I’ve used it to connect a new 2018 iMac with older Thunderbolt drives and to use a 2011 iMac as an external monitor. No issues at all. I was initially worried a bit about the weight of the adapter causing wear on the USB C plug and port, but the fit is snug and secure and running the attached cable through the hole in the IMac stand takes the weight off.

Yes, there are (much) cheaper options, but the build quality on this is quite good and there are no concerns about compatability or reliability.

Works very nicely

I use it to interface a Promise Raid device with Thunderbolt-3 connector to my existing Mac Mini that only supports Thunderbolt 2. While it does not provide full T-bolt 3 throughput, it works. Maybe someday Apple will bring out an updated Mac Mini. For now my current setup provides a large amount of RAID-5 storage that I can share with my Macs, Win 10 box and Linux system.

Does exactly what it should

There’s no getting over this adapter being overpriced if you’re buying it new, or from Apple. That said, it’s the only adapter I know of for changing the physical plug between generations of Thunderbolt. I’m running a 27” Apple Thunderbolt Display from the Thunderbolt port on my M1 Mac Mini and using the old USB ports on the back of the display for stuff that doesn’t require high speed (mouse, keyboard, external optical drive, etc.). This little dongle just greatly expanded the capacity of my new little Mini, so it was definitely worth the money.

It Works! Thunderbolt 3 to Thunderbolt 2 to Firewire 800. But You’ll Pay

The 2018 MacBook Pro only has those usb-c/Thunderbolt 3 inputs (yes, and the standard 1/8″ audio jack, thank god), so how do you get an old Firewire 800 input? I spent hours perusing the internet and buyers’ purchases here on Amazon to figure out how to get my “old” Sony miniDV Camcorder videos to import to iMovie. The older MacBook Pro from 2011 or so had many inputs, including the Firewire 800. So all I had to do was use the $10 DV out to Firewire cable and no problem. With these usb-c/Thunderbolt 3 inputs, you need to daisy-chain two adapters. And it’s a little pricey. But it is the only way under $100 that I could see to do it.

For a grand total of $94+tax, I purchased the $29 Apple FireWire to Thunderbolt adapter. But don’t stop there, because the Thunderbolt is Thunderbolt 2, and not Thunderbolt 3 (usb-c) that you will need for the new MacBook Pro. So, taking a risk of roughly $50 (not cheap), I also purchased an Apple Thunderbolt 3 to Thunderbolt 2 adapter. I figured that I would return it for my money and try some option down the road that might come up. So, the two Apple adapters and the cable I was using before with the old MacBook. But hey, it worked! Very pleased. Pricey option for two pricey adapters, but it will be worth it for the 30 to 40 miniDV tapes I have. And I will be able to import any video output through this particular Sony Camcorder DCR-TRV33.

For those interested, three adapters/cables:

For those further interested, I will post a pic or video of the configuration.

It worked!

I needed to connect an older MacBook pro with Thunderbolt 1 ports to a new Thunderbolt 3 hub for dual monitors and accessory input. The product description is clear that it will not charge Thunderbolt 1 or 2 connections but otherwise would work the same, and that is correct! My old laptop plugs in to my Thunderbolt hub and connects just like my new fancy one with Thunderbolt 3 ports does. As my hub has two Thunderbolt 3 hubs on the back but only one of them sends power to charge the laptop, I leave the Thunderbolt 3 cable plugged into the charging port and leave this one charged into other, non-charging Thunderbolt 3 port on the hub and don’t have to fiddle around with connecting and disconnecting them to the hub. If I plug both laptops in at the same time, the port that charges takes priority (the new laptop) so I make sure I disconnect that laptop before trying to use my older one via the hub. For reference, I have the CalDigit TS3 hub, am also using the Apple Thunderbolt 1/2 cable, and my old Mac is a late-2012 13″ MacBook Pro.

Conclusion

In conclusion, the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter provides a new way to connect two Thunderbolt 2 devices. Apple recommends pairing it with the USB 3.0 or 2.0 to Thunderbolt 2 Adapter (sold separately) to create a full Thunderbolt 3 daisy chain. The adapter is backwards compatible with Thunderbolt 2 devices, but the performance can be limited by legacy devices. Apple included a new Thunderbolt 3 to Thunderbolt 2 cable to connect the devices. The adapter supports video up to 4K 30 Hz at 10-bit 4:2:2 color, audio up to 384 KHz at 24-bit, and USB 3 at 5 Gbps. In addition, the adapter supports up to 20 W of power delivery over Thunderbolt 3.
