    Hey all, I just received my new MBP, its awesome and I love it. However I'm trying to connect it to my late 2009 iMac 27" using the Belkin mini display port > Thunderbolt 2 > USB-C. The cable worked great with my 2011 MBP as soon as it was plugged in it went into Target Display Mode and was able to use as a second monitor. It will currently not work on the 2016 MBP. Does anyone know if this is possible on the new machine? Has anyone else encountered this?

    Perhaps it is the Mini DP > Thunderbolt. I found a Mini DP direct to USB-C on amazon I was thinking of trying.

    Yeah, i think the problem is that you are using the thunderbolt adapter. Thunderbolt 1/2 and mini display port are the same shape, but not the same signal. Previous macbook pros supported display port and thunderbolt on the same ports. I think you want to go from usb c to display port.

    See here:

    "The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter doesn't support connections to these devices:

    • Apple DisplayPort display
    • DisplayPort devices or accessories, such as Mini DisplayPort to HDMI or Mini DisplayPort to VGA adapters
    • 4K Mini DisplayPort displays that don’t have Thunderbolt"

    Yes it did! Apologies for the delay, the item was in and out of stock and I wanted the grey so it took a little while to arrive. I plugged everything in and pressed CMD + F4 on the iMac keyboard, got a black screen while they connected and was in business. Thanks for your help @wlossw !!

    Just a quick update... the Monoprice adapter worked for me.
