    Is anyone using a TB3 Dock for their new iMac? I love this machine so far, but my biggest complaint is that they only stuck two TB3 ports on the back while keeping four USB-A. The problem for me is that I have a USB-C external monitor and a small external TB2 RAID storage box. So that is both of my USB-C/TB3 ports, so no real room for future expansion, unless I replace one of those two purposes.

    So what I am looking for is a TB3 dock that supports 4k 60hz video output (via DisplayPort?) to remove that, plus a second TB3 input so I can connect the drive to that and leave me with at least one more TB port on the iMac. Having a USB port in front of the machine would also be a bonus. Anyone have one they are using for an iMac/MacBook pro that they like?

    I have this on my 2012. Even though it looks really clean I'm not 100% sure I like it.

    You put the hub in a USB port first, then maneuver it under the iMac to get it mounted. But you have to put a lot of tension on the hub--the plastic literally bends--to get it to snap into the vents on the bottom where it's retained and I'm concerned that tension potentially stresses the usb port not unlike taking a plugged in USB cable and pulling hard towards the bottom. While it's not under tension once you're done, now that it's on I'm also not sure how to take it off again without the same issue. Plus, with the possibly more aggressive venting on the 2015+ I'm not at all sure this wouldn't add to noise by being in airflow. And with all that, it's unpowered so you probably can't use all four ports at once for anything significant anyway.

    So I'm just going to leave it there when I give the 2012 to my wife and I think I'll settle for surface mounting a front-facing powered hub on the stand base instead for the new one.
