It's pretty much your only option if you want video and pass-through charging. It works well enough for me.

what does 'well enough" mean? it works perfectly all the time, or sometimes? it's sporadic? or perfect every time. i just read a long bunch of one star reviews filled with complaints. there are some brand new ones on ebay a lot cheaper than apple. but it could be a pain returning. these are genuine, full apple warranty.

Well enough means that it does exactly what it's advertised to do. It's not perfect because the cable could be a bit longer or even detachable, and with numerous peripherals attached, it's possible to run out of power and your external drives might dismount unless you use a powered USB hub. But it does exactly what it's supposed to do which is charge the Macbook while providing video and usb outputs. There isn't another device available anywhere that can do that.

As for the 1-star reviews, I'm fairly certain it's sour grapes from people who have too much time on their hands. Look at the reviews for the stock usb-c charger which works flawlessly - heck - it does an 80% charge in about an hour! Yet there are still a ton of 1 star reviews for it as well.

Works perfectly fine on mine. I connect a HooToo USB 3.0 3-port adapter with Gigabit Ethernet for expansion.

I think people get pissy because of the cost and the "yet another dongle" stigma. Either that or its android users wanting to troll again :). I had an HDMI one that I used without any issues as well.

Depends on the hardware you're using it with. For example, due to limitations with the monitor, it won't work with Dell U2711 at full res. So make sure you check your situation before springing for an expensive adapter! I think I'm going to wind up buying a new monitor.

That's hardly the Macbook or the adapters fault. Dell sold a monitor with 2560x1440 resolution that can only accept 1920x1080 through the HDMI port!!

True, a lot of monitors during that timeframe used HDMI versions that only went up to 1920x1080. I believe that the Apple HDMI adapter does support the newer versions of HDMI that would allow for 2560x1440... there was someone on here who tested the adapter on a newer monitor and it worked at 2560x1440 over HDMI. I'll see if I can find the link.

I'm looking forward to someone who makes a mini-displayport version of this adapter w/ power and an extra USB port.

The Apple adapter is capable of 3840 x 2160 at 30Hz and 4096 x 2160 at 24Hz. I've used it with my 4k monitor at 30hz.

I think it is kind of worthless to run at those refresh rates unless you are going to watch a movie, but that is just my opinion. 2560x1440 at 60 Hz is much better if you can't get 60 Hz on the 4k side of things.

A couple of confirmations that 2560x1440 at 60 Hz is feasible:

I wish Apple would just tell you what version of HDMI the adapter supports instead of waiting for someone to beta test it...

To me the stigma is the fact that the darn thing costs $79.00. Base model sets you back around $1300, throw in $80 dongle and other accessories and this machine is approaching refurbished 15" macbook pro retina levels. But the point of this machine is its portability. FWIW I picked up this dongle at BestBuy open box for $59.99, so there is that...

I have the hdmi and the vga dongle from Apple and they both work fine all the time. Have used the hdmi dongle for over five months.

I have this adapter (HDMI/USB) and it works without an issues. I connect it to my 24" Dell monitor at work and use the USB port sometimes for portable drives. I haven't had an issue in the three weeks I've been using it. I don't connect many peripherals wired though so I don't have any experience with connecting a hub and a bunch of stuff to it. Most of the time it's just power and HDMI as my mouse and keyboard are bluetooth. Works great for me so far though. But yes, it is a bit expensive. Oh well, right now it seems its that or nothing.

Yes, it's a monitor limitation, not a problem with the adapter. Has anybody tried the adapter + HDMI to displayport adapter with the U2711? I really want to avoid buying a new monitor, but can't look at a 1080p screen any more.

Mine work perfectly fine. No issue at all. Hook up to a dell s2440L display as secondary screen.

Been using my adapter everyday since April 2015, no issues.

I use an HDMI->DVI cable to get the 1440p resolution, and it works fine. You might want to test it on your U2711. I have the U2713HM.

So this is sort of reassuring... I'd read reviews, and it sounded like this barely functioned.

I've heard a lot of people saying the 2015 Macbook has problems using external drives, that they randomly disconnect, but from this thread it sounds like that might actually be a power issue, that they need to use this adapter, then connect a regular powered USB hub to the adapter, and then everything should work?

The reason I'm potentially interested in a 2015 Macbook is my main system for work is an Alienware M17x-R4, which I love, but sometimes I could really use a second system when I'm doing stuff full screen on the Alienware, to like just have my email up on the second system... I was thinking the Macbook seems like it would be good enough for some basic stuff when I'm doing heavy-duty stuff on the Alienware, and I could just sort of sit it on my main notebook's keyboard lol.

I do need Ethernet though, and to have it keep charging, so need this adapter to work!
