it is not working with mac , and i asked for return and no one respond

Like many people who have bought a new Apple laptop recently. The move to USB-C / Thunderbolt 3 has been extremely disruptive. I spent a fortune on new accessories. One thing I wasn't prepared to do was throw away my Belkin hubs and Apple Cinema monitors. I tried Apple's own Thunderbolt 2 - Thunderbolt 3 adapters; and they worked inconsistently. One day I would switch on my computer and the monitor or hub wouldn't work. For no reason. StarTech are a respected video brand, who used to make a well respected Thunderbolt 2 hub, so in desperation I decided to give their adaptors a chance.Let's get the negative aspects about them out of the way first. They are bulky, with the electronics coming in a case about the size of a stack of playing cards, rather than a small pack of chewing gum like Apple's own convertors. They're in a shade of dark grey only a sys.admin could love.But once you get over these cosmetic issues you get a product that just works. It is ironic that I had to go to a non-Apple supplier to get this most Apple of attributes. I can wholeheartedly recommend these convertors.

Warning!!! This is no good for plugging into the Thunderbolt 2 connector on your Mac. It only works the other way around which is not explained by the seller

Works perfectly under Linux (Ubuntu 17.10) on a Dell XPS-13-9360. Unlike the 30Hz version of this which worked for a period of time and then seems to cut off one, alternate between them, or both - I guess because it was overheating(?) - this one seems to run very smoothly. I've been using it for a day and a half already and no problems at all. I had been forced to use Windows in order to use my Dell DisplayLink dock (since DisplayLink doesn't work under Linux very well at all, if at all), but now I can stick to Linux - I've not even bothered to try this on Windows because it has been rock solid. Startech don't support Linux, but it works very well indeed - I guess they don't due to a matter of support personnel/training, rather than the device itself.BTW, even though I am using Linux, my config is dual boot, so I can test on Windows too; so I they did support me for the 30Hz version (it had the same behaviour on Windows) - and they give really good customer support.FWIW: xrandr outputScreen 0: minimum 320 x 200, current 6016 x 1440, maximum 8192 x 8192XWAYLAND0 connected 1536x864+1920+0 (normal left inverted right x axis y axis) 290mm x 170mm 1536x864 59.80*+XWAYLAND1 connected 2560x1440+3456+0 (normal left inverted right x axis y axis) 600mm x 340mm 2560x1440 59.91*+XWAYLAND2 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 500mm x 310mm 1920x1200 59.88*+

I purchased this adapter to use it in conjunction with Apple's Thunderbolt to Firewire adapter.I have an amazing Apogee Duet sound card, whose original interface is Firewire 400.Using this adapter, I can now enjoy it on my 2016 MacBook Pro.This adapter gave a new life to my Firewire audio interface!Highly recommended.It is expensive, but worth the money if you have an expensive device to adapt to USB-C.Apple's Thunderbolt 3 to Thunderbolt 2 adapter, only works for native Thunderbolt devices.Not with adapters.I have also tested it with a Firewire hard disk, which worked without problem. No driver needed.The disk was a completely plug and play experience.

This adapter works perfectly. I use it to connect my Thunderbolt 3 laptop to my Caldigit TS2 docking station. The main problem it has is the "embedded" USB-C cable. It is very short and therefore fiorces you to keep the device next to the laptop. This is not always practical. For example, if you have a laptop stand on your desk, or even a laptop arm to place your laptop, the adapter will generally hang from the laptop in the air, applying tension to the wire.I have a laptop arm which is the worst as the laptop is quite high from the desk. I used double-sided tape to attach the device under the tray of the arm and run my TB2 cable from the device through the arm down to the docking station. Even so, doing a 180 turn with the cable to insert into the laptop is very tight and I think will eventually wear the cable out.I would prefer it if I could stick (with double-sided tape) the adapter on my docking station instead, but this is not possible due to the length of the attached cable.A much better design would've been if they simply had two female ports (TB3 and TB2) so you can run your own TB3 and TB2 cables, of whatever length you need. This would've been much more versatile and reduced the cost of the device.
