    Seems to be fixed!

    I have both a LG UltraFine 5K and an LG UltraFine 4K. The 4K worked for me out of the box, except for the chronic wake from sleep issues that have been heavily discussed here. I simply unplug the USB C cable, wake and then replug in. A pain, but not a deal breaker.
    In setting up the 5K I got screen flashes, black screens, kernel panics, locked Apple MacBook (late 2016) 15 inch issues. It was unusable. I put it back in the box, and was going to return. BUT - Sierra updated to 10.12.3 - and I decided to retry.
    Note: I also updated Magnet (an App Store screen real estate management app) which I suspect may have been part of the problem.
    Result: The 5K and the 4K are working now for 2 days straight with no issues (except intermittent sleep to wake). I did have to plug in the USB-C cable first, then the Thunderbolt 3 cable. Doing it in reverse order, does not allow the Mac to recognize the 4K.
    For me, for now, all is working. 4 stars for sleep to wake and the fact that it's only been 2 days, and I'm not sure this "working" streak will be sustained.

    Monitor DO

    The 27" 5K LG monitor arrived DOA (for 2016 15" MacBook Pro). I chose this monitor as I assumed Apple had thoroughly tested it with the new MacBook Pro and it would function better than its competition. However, to my disappointment, I found that the Mac wouldn't recognize it. After speaking with Apple Geniuses (they first said they didn't know anything about the monitor - it's really LG's problem), I was able to get a replacement monitor ordered. When it arrived it was recognized, but it could not be selected to run at native resolution (only lower resolutions using Scale mode in System Preferences). It also has the well-documented awakening from sleep non-responsive bugs that are still present in MacOS 10.12.3. I expect more from Apple and Tim Cook. Don't buy this until Apple and LG can work through the bugs. Also, Apple needs to accurately calculate the "Average Review" score for this monitor as it is overstated.

    Useful and Cool, but Not Perfect

    Look, this monitor is a LOT better than the 1 and 2 star reviews suggest. I actually like the sleek black look. Plus, it's EXTREMELY useful if you have the MacBook Pro. It expands its functionality to full desktop level with the extra USB-C ports on the back, and it looks beautiful with its high-resolution display and easy setup with your computer. It is a great size, is weighted well, and better yet you can plug two of these in if you want two displays, which I do (I do a lot of creative app use with both music and video.)

    Now, the bad: it doesn't function well with anything BUT the MacBook, thus ruining my dream of playing PlayStation 3 on one screen while monitoring my session on another (call me glib, but I have my creature comforts.) So you can't run it with an HDMI device. Also, the webcam on it is really, REALLY bad looking. I was really disappointed in this because it was one of the main reasons I bought it, I was hoping the camera and mic quality was at least almost on par with the pixel quality. And this is a bit nitpicky, but USB-C requires a lot of adaptors still so you'll need a bunch of Apple branded cables that connect one to another, which is kind of annoying right now.

    But honestly, the camera isn't enough to make me dislike the monitor. If you have the new MacBook Pro, it is a dream. If not, I definitely would not recommend this because it doesn't work well with anything else.

    Does not work, flickers

    Monitor arrived today and the picture flickered on or off when using with a brand new 2016 15" MBP! Could not get a picture for more than 20-30 seconds. I called LG support and they said the following:

    1. Monitor will not work near a WiFi router!
    2. MacBook must be positioned to the left or front of the monitor. Seriously?
    3. I might have a defective cable; they are sending a new one but I'm probably going to return this because they said it could take 10 business days to arrive.

    Sound and charging do work, but the volume is uncontrollable. It is extremely loud on even the lowest volume settings.

    Unbelievable issues for a nearly $1,000 display that was touted as designed for the new MacBook Pro.

    This is not what I paid for

    Yes, the quality of the display is excellent....when it works.

    Like many others, I have numerous problems making it work with the new MacBook Pro 2016 13" with Touch Bar:

    1. Computer crashes 100% of the times I disconnect the display with the lid closed.
    2. Occasionally the image of the mouse gets stuck on the screen, it does not go away unless I reboot.
    3. Flickering and some odd lines appear in the display at random times.
    4. The display blinks (it turns black for a millisecond) every 2 to 3 minutes.

    For a while I thought that my unit was defective until I read all the other reviews.

    This is the first time in many years that I have had so many issues with an external display. Very disappointing.

    Horrible handoff

    Chances are, like mine, that your macbook is gonna crash when you plug/unplug this thing.

    Crashed computer every time computer tried to wake from sleep

    I would give this monitor 5 starts because it's great in every way except for one horrible issue. This thing crashes my 15" touch bar MacBook Pro every time it goes to sleep and tries to wake up. I lose any unsaved work and it is very frustrating. In my 10 year history of using Mac I probably get one crash per 6 months, but now with this monitor it happens multiple times a day. I am running the latest Mac OS 10.12.2. It is disappointing that Apple puts their name behind a product that basically doesn't work at all. If anyone at Apple tested this product for more than 1 day this issue would be readily apparent to them.

    Only works some of the time

    My Mac now constantly crashes, reboots and has strange issues connecting to the new LG 5K monitor.

    When it works, it's fantastic...problem is that is rarely the case.

    Beautiful Picture, When It Works...

    I have to main issues. 1) Sometimes my MacBook (late 2016 15") turns psychedelic. Like, tons of random very bright colors and extremely difficult to see content on the screen. 2) Often, when I plug the monitor into the laptop, the monitor starts out on the dimmest setting, no matter what the setting was the last time the screen was plugged in. This seems to happen inconsistently, but typically multiple times per day.

    Enough is enough, crashing 10+ times a day

    The title of this review says it all.

    I purchased the LG UltraFine 5K Display alongside the 13" MacBook Pro (Late 2016). Sadly, from day one my experience has been nothing disappointment. This is no exaggeration, when my MacBook is woken from sleep mode more often than not it will crash, rebooting the machine. This has happened well over 100 times in the last 3-4 weeks. I have put up with the display in vain hoping that there would be some magical software update that would fix everything but am running out of hope.

    There are other issues. Music controls don't work when using Magic Keyboard i.e. Play/Pause. Sound is also an issue, just way off, too loud.

    To be fair, the display is beautiful and I like the fact that I can charge my MacBook via USB-C. Adjusting the monitor height up and down, angle tilt forward/backward is also nice.

    I wish Apple had kept producing the Apple brand display in-house, same feel as external features as the iMac for a side-by-side experience.

    If you are considering on buying this display, sorry Apple, I wouldn't recommend it.

    Poor Handoff with 15" MacBook Pro (Late 2016)

    I like the display of the monitor, and the single cable for power and video, but...

    When you unplug the monitor, especially when a 15" MacBook Pro (Late 2016)'s cover is closed, there is a 99.9% chance it will crash the 15" MacBook Pro (Late 2016)!

    It didn't crash once; just after I upgraded to macOS Sierra 10.12.3 (16D32).

    Also the Belkin USB-C to Ethernet adapter that Apple sells, when plugged in to the monitor, will sometimes not initialize when the monitor is plugged into a 15" MacBook Pro (Late 2016).

    Like others, I expected this to work as well as the Thunderbolt Display that it replaces.

    Trash. Do not buy.

    These monitors are trash. I have one. Regret replacing my Thunderbolt Display with it.

    Things I have experienced while using this monitor with my Late 2016 13" MBP (with Touch Bar):

    1. Kernel Panics when connecting monitor or on boot with the panel connected.
    2. The monitor cable is loose at the back of the monitor - wiggling it very gently will cause it to disconnect and occasionally cause cocos kernel panics.
    3. Waking my Mac from sleep has about a 50% chance of not turning on the external monitor.
    4. Video display corruption on the built in laptop panel when connecting the LG.
    5. Enormous mouse pointers left on external screen - I end up with two mouse pointers. One giant one and the normal one. I have to disconnect and reconnect the monitor to get rid of the giant rogue mouse pointer.
    6. Connecting the monitor causes my built in laptop LCD panel to "forget" its brightness settings (and thus I have to constantly tweak my brightness settings when connecting the monitor).
    7. If I connect the LG monitor but already have headphones plugged in to my Laptop, the LG hijacks the audio and starts playing audio out its built in speakers (often very loudly) - not good in an office setting.
    8. External USB devices connected to the monitor sometimes don't work. Eg, Apple USB 101 key keyboard doesn't respond or USB external HDD not detected or mounted.

    Also, the stand is very bad and the monitor is very wobbly. There is also no cable management which is terrible when you have to have so many dongles connected and the display cable is so loose and temperamental.

    Avoid this product like the plague. Apple should be very ashamed of itself for endorsing this pile of ****.

    Crashed my MBP 2016 15" every time I plugged/unplugged it

    I really really wanted to like this monitor, but I had the same issues that so many other people seem to be having. When it worked the display was great. However, my 2016 MBP 15" would crash nearly every time that I plugged or unplugged it from this monitor. Occasionally it would work, but I could never figure out what conditions would lead to it working without crashing. It was completely unacceptable for a monitor and laptop of this price.

    It may be that the issue is entirely with Apple and not with LG, since it is my Macbook Pro crashing, but these terrible issues should have been found during basic testing of the monitor before releasing it.

    I tried resetting the SMC, NVRAM and multiple other suggestions, but none worked. Someone did suggest disabling filevault, but I didn't want to do that and it seemed like a bad solution if it really was the only way. I returned the monitor with one day remaining on my return window since I could never find a solution.

    Do not buy this monitor unless you like taking risks. Perhaps it will work for you, but it is not a well-tested product.

    works perfectly for me

    It doesn't come cheap but the display is gorgeous. Best picture i have every seen on a monitor, very crisp. I have not experienced any of the issues other users complained about. Connection with my MPB 15" (late 2016) works just perfectly, it never crashes. Monitor doesn't disconnect nor flickers. Might be they had some defective units, mine so far does what it promises.

    It's alright and the audio levels are annoying

    It's a monitor. It works, but the audio controls are awful. The step between the first bar and the 2nd bar when changing audio levels is huge, so don't expect to listen to music quietly at night. The docking experience isn't great. It's a disappointment for the money. Much like the MacBook Pro with Touch Bar, buy it if you need it, but don't expect to be delighted.

    Received two defective units - beware

    I was excited to purchase this product shortly after getting a new mac book pro. The first unit arrived and would not stay sync'd with the laptop display. It kept turning on and off. Sometime the screen would appear half orange and half black. I returned the first one and the second one was worse. The screen would not turn on at all. The laptop acknowledged it was being charged by the monitor but would not recognize the display. It never turned the display on when connected.

    The monitor itself appear flimsy (cheap plastic) and the custom cable which might have been the problem in the first unit does not fit snuggly into the monitors Thunderbolt 3 slot.

    This was clearly rushed to market without adequate quality control.

    Tried to use it with the new high-end MacBook Pro 15.
    Never got it to work: macbook would sometimes freeze while plugging in, display flickered and went black first few times I tried to plug in MacBook, then even flickering stopped, just stayed completely blank on any operation.

    Return defective unit to the Apple Store and was going to order the new one (they were out of stock for replacement), but after reading reviews decided to pass.

    Apple, shame on you, this is not the experience I payed all this money for MacBook for.

    Great monitor, terrible integration with the latest MBP 2016

    I am using the monitor with my brand new MBP 2016 15" with the AMD GPU 460. The display is fantastic. This is definitely as good as I expected it to be. But the interaction with the MBP is REALLY REALLY BAD. Even after the latest upgrade to Sierra 10.12.3 the MBP crashes every time it tries to come back from sleep mode after disconnecting and connecting the MBP via the supplied TB3 cable. In addition to that any external USB accessory (mouse, keyboard, etc.) attached to the monitor is not recognized after the MBP has been unplugged and re-pluggeed back. I am very disappointed with this solution, I hope Apple and LG will fix this via FW update very soon.

    LG 5K Disaster

    Received the monitor today and it worked great for a solid fifteen minutes. The first time the computer went to sleep that was it. I could not get the monitor to fire up again. A call to Apple support yielded not better results. Apple support wanted meet to book an appointment at the Genius Bar for mid next week. No thanks! This monitor is going to get returned. I should return my 2016 MBP 15 at the same time. It has been nothing but trouble since I received it. I've never had so much trouble with a new lap top before. Mostly with how it interacts with my Thunderbolt displays. At least I can get the Thunderbolt displays to render an image with a couple of reboots.

    Terrible purchase.

    This monitor is unusable. It worked fine for about the first hour when hooked up to a new 2016 13" Macbook pro. Then it started crashing periodically whenever HD videos were viewed in full screen mode. I also encountered the flickering, fade to black screen.
    Eventually it would crash the MBP, without fail, at least once every hour. When in clamshell mode, it would periodically fade to black, and sometimes come back. Then eventually it would crash, and actually send the MBP into recovery mode when I tried to turn it back on.
