True Tone Problem Since Update to 10.14.6

From what I have experienced since this post was launched confirm what all the contributors said :

nothing seems to solve this problem : reboot, PRAM/VRAM reset, power controller reset, reinstall ...

I did note something though : It happens mainly when you have direct light on the screen.

At the moment I am in front of my window, the light is bright, and since hours I have zero flickering.

While when the light is hitting directly the screen (and then the sensor) it seems to provoke this crazy behavior from blueish to normal.

Same issue here with MBP 15" i7 2018... Although it only started happening after my display was replaced due to appearance of vertical stripes. Seems like a vicious circle, heh.

PRAM/VRAM reset and reinstall didn't help either, I'll probably take it to a repair shop.

Same problem.

I'm have been working with Apple support for this problem, even send information from my notebook to them, send videos showing the problem.

But at the end, they said this is related with software and closed the issue.

I'm currently waiting for Catalina, maybe that will fix the problem.

I agree that this is releated with software, but they are suggesting that this is releated with 3rd party software that I'm using. They didn't accept that this is releated with operating system. At least not to me.

The True Tone glitch problem hit me after I upgraded to macOS 10.14.6 / MBP "13 2018 model almost a month ago. Very annoying!

The problem occurs occasionally and on some specific locations. When the late-afternoon day light shines directly onto the screen sensor, it usually occurs. The screen turns from warm colour to cold one several times in a second. But when the laptop is used at my home where another light condition is around, the glitch never happens.

It seems we have to remind Apple of this issue. So far all tech supports from Apple are nothing but a waste of time. The technicians guys only tell me a long list of routine check-list.

Both my laptops 2018 15" MacBook Pro at home and 2019 13" MacBook Pro at work are now having this problem.

The only thing they have in common is 10.14.6.

It's now more than a couple of month into it and nothing has been done by Apple, which is extremely annoying.

My friend is using Catalina since early betas and don't have the issue so I have hope that update will fix the issue.

They are probably working hard to fix bugs in Catalina so they don't care about us much now.

The problem is that Upgrading to Catalina will cause a lot of problems to my work because most if the apps I use will not be compatible with Catalina.

they have to fix what they did in Mojave first. I’m so frustrated of how apple deal with this issue. I called many people from apple support and all they do is wasting my time and get me more frustrated. For this issue and more!

That's why I haven't bothered calling Apple. I don't want to reset no NVRAM/PRAM, no fresh installs of macOS either, not letting them waste my time with irrelevant troubleshooting walkthroughs. This clearly started happening right after the update to 10.14.6 and can't be coincidence that ambient light sensors decided to go bad at the same time for all of us.

I'm having this problem across both of my macbooks. The issue is especially severe when I'm sitting agains a teal wall - the laptop can't decide between the warm color of the human face and the cool color of the wall and goes absolutely nuts flickering its color temperature back and forth.

True Tone is absolutely awesome when it works. I love it. But on Apple laptops it's just broken since 10.14.6, and no one at Apple has bothered fixing it so far.

Very sad.

No changes for me,

I have 2 laptops 13" and 15", 2018 and 2019 models, and when I'm sitting against a teal wall, True Tone is flickering like crazy on both of them.

The issue had started with 10.14.6 and since then never resolved. No nvram/pram reset neither upgrading one of the laptops to Catalina helped.

It's extremely annoying and Apple support is just wasting my time, no help at all.

Same issue for me on my two macbook pro 13" and 15". I have it off when working on photo editing but very annoying when on. I will not update to Catalina for software compatibility. Not happy with Apple and the lack of aknowledgement of this bug

I certainly am still having the problem. I've chatted and e-mailed Apple but get no specific response other than "any time a problem has been reported, then we are working on it." Still VERY frustrated.

This is very disappointing from apple with their so expensive product. I had enough with their products, they make me suffer and wasting my life to tackle their problems. And their staff are not aware about their problems. All they do is wasting my time and frustrate me more!

Same problem here, 15-inch 2018 MBP. Very frequent True Tone switches (multiple times / minute) and occasional screen flickering. Started right after the update to 10.14.6.
