Advance apologies if this has been covered before; I didn't find it, but please point me in the right direction if I've missed it. I've also posted this on Apple's Support forums with no replies. As many folks have purchased the new MacBooks with only USB-C/Thunderbolt, I am trying to accommodate new devices/cables meant for the new MacBooks with my existing MacBook Pro Mid-2015 (last year's model). I have purchased the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter (http://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter?). I also have an Apple-branded Thunderbolt 2 cable (male<->male). This allows me to connect the adapter to my Thunderbolt 2 port, and it is stated on the Apple Store page for the adapter that "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." Yet, when connected as described, I clearly end up with a male USB-C (Thunderbolt 3) cable end. Already, I have had several folks appear with a USB-C flash drive, and others appear with a USB-C cable connected to their iPhone. Clearly, I cannot connect these devices, as I have two male USB-C ends. I went into the Apple Store, and was told "try checking Monoprice for a coupler." Not only does this not sound great, but they don't seem to carry a coupler. Furthermore, I would like such a device to support Thunderbolt, not just USB-C: I'm sure any day now someone will show up with a Thunderbolt 3 device (perhaps a display, or external HD) without a removable cable, which I'll likewise be unable to connect to. Help?
