Overall, I've been very happy with the StarTech Dock. I must admit two points of frustration, which may or may not be caused or exacerbated by the dock, however. The first is a recurring, albeit infrequent, issue where external keyboard input will not wake the external display. I suspect this is a Mac issue, rather than a dock issue, but due to the difficulty of reproducing the issue its hard to say for sure. The second is the need to provide several keystrokes on my external keyboard and wait approximately 10 seconds for my external display to awake. I suspect this is a combined issue of the Mac and energy efficiency feature(s) of the monitor, but, once again, I haven't sufficiently troubleshot the issue to conclude for certain that the dock is not at all to blame. Be well, Aaron
