Macbook 2016 HDMI output flickering

I've had this problem for over a month with my MacBook. Now it's happening with the new PROs and not a peep from apple. Unreal.

I forgot to mention that I upgraded to macOS Sierra Public Beta 3.

same problem here, also usb devices have problem. I will recommend all people not to go for the new macbook usb-c only line.

all my usb devices get unstable connections. hdmi as well. better cable help, pram reset helps, but don't solve the problems.

not sure if it is a firmware problem or if usb-c plug is not stable enough physicaly.

Reporting back. I downloaded and installed the beta on Nov 21 (5 days ago). I've had 2 glitches so far. It's a lot better.. but still.

share your experience in all forums and review comment section. only this way people will avoid buying and apple will have to act. all connections through apple usb-c ports are unstable and have problems, even power charging.

Hey kenofstephen I know that feeling. I've now had total radio silence from my engineer for 2 weeks. I invested a lot of time testing and reporting this, and a not insignificant amount of money buying additional adapters. I feel I'm owed as a minimum at least an update.

As it happens I'm still stable on the devices I need to display on after over a week of use. This is on the beta 3 release. It doesn't sound like it's a perfect fix for some people but the fact some people are having success points towards a software solution being viable. Which is good!

Don't give up yet! Silence + beta software which improves things (or as a minimum changes things) might be our best indicator that Apple are definitely aware of the issue and working to resolve.

Everyone - several people have stated that there are rumours of the new MBP having similar issues. I've had a google and can't find any evidence of this. Can those reporting please provide a reference URL?

I can confirm the new MBP has this issue. I have received my MBP (15 inch) on Wednesday. One of the first things I did was connect two external monitors. Within a few minutes, one monitor started going black for a second a couple times a minute. Maddening as ****, as most of you have experienced. Long story short, my research lead me here. I installed beta 3 and purchased Apple's pricey dongles. Things have been working since then.

I'm sorry for those who have not found a solution. I was contemplating returning my $3500 MBP if I couldn't get it to work. Most here don't have that option. I feel for you, Apple needs to get this figured out.

Just got my 2016 Retina MacBook back from the AppleCare repair shop. They replaced the following components (as listed on the repair receipt):

- Logic Board, FCC, 1.3GHz, 512GB (item # 605-01248)

- Display Assembly, Space Gray (item # 605-01265)

- I/O Board (item # 605-01294)

- TCON flex cable (item # 632-00651)

The issue persists. To be clear, replacing the aforementioned components did not fix the problem. It seems like this is either a hardware-wide product issue (less likely) or an OS-level issue (more likely, as we've seen improvements in the beta).

This entire experience has made one impression in my mind: Apple does not care about transparency with customers. I had a Late 2016 MacBook Pro with Touch Bar on order. I cancelled my $3500 order with Apple because of the way they've handled this issue.

Apple: you need to make things right with your customers with regards to this issue.

I have recently got LG UltraFine 4K, the problem persists, with the supplied cable. So it should not be a problem in adapter or cable.

Previously I experience the problem with the official 1-to-3 adapter and Dell P2415Q.

A shutdown-start cycle eliminates the problem mostly/completely (not sure).

Well...

seems to me if you are a software company and want free beta testers you give away beta software. But if you want to keep them working for you, you have to give something back. As I see it, two things are missing on this relationship:

- no logs of what a given beta brings/solves

- no feedback on issues that tester is trying to help

just my 2c.

My take on new MBP:

There are two main uses for laptop computers: on the move and stationary.

ON the move batttery life, size and weight are mandatory. They dropped the ball by putting too much emphasis on weight and leaving battery life behind. The space between cells could have maybe give 2 more precious hours of battery life. I would happily trade 100g of weight for that.

On stationary you want hassless PnP compatibility with displays and peripherals. Now we all know how Apple is (not) handling USB-C connections properly.

All this is an even more overpriced laptop. You can ask the price you want, as long as you deliver accordingly.

Again, my 2c.

Running Sierra 10.12.2 Beta since a few days now (without reboots but lots of sleep/wake cycles). Looks good, no more flickering so far.

Testing the macOS Sierra 10.12.2 beta 3 for almost 2 weeks now. So far no flickering with external monitors and projectors and MINIX NEO C adapter over VGA. Though few issues with the LG 27UD88 monitor over the USB-C cable. So definitive not perfect but far better then the 10.12.1.
