Macbook 2016 HDMI output flickering

Does anyone have any new development? Do we think this will be fixed with a software update?

Another sufferer here. Am living in a land of multiple daily reboots as I go about my business, something I thought was a thing of the long distant past 😟

Do we know whether this is a problem for all 2016 MacBooks or whether some of them don't flicker?

How do you install that driver kenofstephen? I can only find windows drivers online.

I have the same issue, and also issues connecting to a LG 27UD88-W external monitor via USB-C.

Here's my experience:

- Purchased a MacBook in May 2016

- Started experiencing screen flickering, screen blacking out for a few seconds, and kernel panics related to graphics when using a Multiport Adaptor

- Returned to an Apple Store in August 2016 and replaced for a brand new MacBook

- Still experienced issues with the Multiport Adaptor

- Purchased an LG 27UD88-W display which connects directly over USB-C in the hope this would fix the issue

- Now have problems with the screen blacking out constantly, or display signal being dropped completely. The setup is pretty much unusable :-(

My colleague has the same set up (MacBook 2016 + LG 27UD88-W) and has exactly the same issues.

With the discontinuation of the Thunderbolt Display it really feels like MacBook customers have been left stranded without an a viable option for external displays... here's hoping Apple fixes this situation soon.

I believe he's using the MacBook with BootCamp for a significant portion of the day...

I'm pretty much in the same boat - bought a 2016 MacBook in May, tried a "cheap" monitor adapter and worked my way up to the Apple Multiport, as that was the only one that was even remotely reliable connected to my monitor (Acer K272HUL). Of course, because I don't have AppleCare, I don't have any support other than to drive an hour to the nearest Apple Store. I thought at one point that blowing dust out of the USB-C connector was helping, but in truth, it wasn't actually solving the problem. Pretty much just reboot it every morning now, as that seems to be the only way to keep the thing from constantly blacking out on me. If this isn't a problem with every m7 2016 MacBook, it's got to be pretty close...

Gotcha. But others are having this issue with just straight Mac OS right? I am.

I *only* use Mac OS and I have this same problem.

Yes, I only run macOS (Sierra Public Beta/GM and El Capitan both have the issue).

Been chatting with a lot of advisers at Apple. They have all told me they are unaware of an issue or any sort of fix. The next step is for me to take it into the Genius Bar and they're going to run diagnostics...

Saddening 😟

So, have you made any further progress with Apple support? Have they asked you to perform any other tests? I'm long since out of the 30 day support period, so I can't even file an issue - only recourse would be to drive to an Apple store and hope the problem would manifest.

Apple won't be able to fix anything over the phone. The advisors I spoke with were very patient but they didn't seem overly convinced about the issue. I don't blame them -- I can't even reproduce the problem on certain displays...

I will take my Mac to the genius bar this weekend and keep you all posted on what the tests they run.

I have been told by multiple advisors, however, that they have no information about this sort of error. It took them all by surprise.

I mentioned this thread and I was told that sometimes multiple people can have the same symptom but doesn't necessarily mean we all have the same problem.

What I told the advisors:

a. HDMI output display cuts out periodically anywhere from every 5 minutes to every hour.

b. Soft rebooting the OS solves the problem, until the computer goes to sleep again.

c. I've tried third party adapters and the official Apple adaptor. I've also tried multiple HDMI cables. I cannot reproduce the problem on my TV at home (Toshiba); however, my display at work (Sharp) has the issue.

d. I've tried resetting the SMC and PRAM and reinstalling OS. None of these have helped.

If they say they are unaware of the issue, ask them to look up Apple Care Case # 1184045304

I've been working for over a month with them do diagnose / debug. I've sent countless logs, screenshots and even photographs/videos. I've re-imaged the device, I've reset PRAM/SMC, I've tried all sorts of different cables/adapters/monitors. As they say... "NOT IN OUR HEADS" ... this is a real issue.
