Macbook pro retina flicker

I have had the same issue: My MacBook Pro Retina 15inch screen has been flickering whenever I used WiFi. The flickering goes away when I turn off the WiFi. After bringing in my MBP to the apple store twice, they told me it may be due to the WiFi antenna embedded behind (inside?) the monitor that is causing the flicker. Since the flickering showed up within one year from purchase they replaced the screen for free, and now the flicker does not show up at all. So in summary, the problem (at least for my case) seems to have been a hardware problem with the screen. Hope this helps anybody.

For me, it happen randomly. They will remplace the clamshell

The guy at the apple store want to change the logic board. He will do some test after the replacement, but if he detect nothing, he will not change the screen

My Mac will stay to the apple store all the time the screen will not be changed. I will not accept that shi*

Resetting the PRAM fixed it for me

I have a mid 2012 MacBook Pro Retina and a couple months ago I had the same screen flickering issue on my computer. It had never happened to me before, it starting happening in the middle of a game I was playing. The screen started to flickered in random ~15 sec intervals.

Somewhat similar to this.

After around 30mins it got worse... Instead of just flickering the screen would go almost completely dark in ~10 sec intervals.

At that point I had enough and the first thing I did was restart my computer. I tested if that fixed the problem, it did not. I then went on to reset the PRAM (CMD+OPT+P+R on restart) and that did the trick. A couple months have gone by and thankfully I have yet to see the issue pop up again. I'll keep you guys posted.

I've had a strange split second flicker since receiving my macbook pro 15" retina in 2012. It only happened once an hour or less but it drove me nuts since i knew it was probably a hardware issue. It happened very randomly and once i found you're thread i called apple and they told me to reset the pram and other boot stuff which never eliminated the problem (came back after a while). I finally was redirected to an apple store. I explained the problem and they were very courteous. I never was able to duplicate the problem in store nor film it. They first did diagnostic which reveiled nothing was wrong and was a litlle bit dissapointed since i knew the problem would come back which it did. I came back the day after and they took in the computer to replace the screen. I am happy that they took my word for it since i am having no problem with the flicker since the replacement of the clamshell. thanks apple!

I fixed the problem changing the WIFI channel on my router settings to "1 - 2.412 Ghz", from "6 - 2.437 Ghz" and now my Mac never flickers. Seems like the wifi signal intereferes with some component on the Mac. Try it and see if it works.

I used the fix proposed by showerkv, and it seems to have worked. It's been about an hour with no flickering. I hope that I don't have to wind up back at the apple store, can't imagine what I'd do without my MBPr for a day, much less a week.

Strange behavior returned after I updated to 10.8.5 today. I am bummed, it was SO nice not to have the flicker. The same fix that was referenced by showerkv didn't work this time around 😟.

MusicallyCursed's solution worked for me. Seems the WI-FI channel/frequency did affect the screen

I am having the exact same problem of screen flicker. The flicker comes and goes, but seems to be coming more frequently.

Some have said it is related to WiFi interference. But I have tried turning the WiFi off on the lap top completely and I still get the screen flicker.

This Macbook Pro Retina is an almost $5,000 machine! Amazing to me that Apple does not atleast have strict quality controls on lap tops that are this expensive.

If they really cared about their customers more than they do about the hedge funds that hold their shares lately, they would do a recall on these Macbook Pro Retina lap tops. I suspect the only way to get their attention is to do a class action law suit. Of course, that's not something I want to get mixed up in, I just want my $5,000 lap top to work properly. It is less than a year old.

Well the place to get satisfaction is with Apple. Feedback to them and than sending it or taking it back to Apple to fix it. These are just user forums.

Feeback, sure. I bought a top of the line lap top precisely because sending it back for repairs is not an option. Try doing that when you travel 40 weeks per year - it doesn't work. Checking the forums and commenting because I am hoping someone has a fix.

I have counted on Apple's quality for 10 years. Just disappointed they dropped the ball with the Macbook Pro Retina.

Even though I am extremelly disappointed about the fact that my Macbook Retina flickers, I understand that there isn't a company out there who makes the perfect product. A product that is in perfect working condition 100% of the time, even though it might be brand new, is just fantasy. We are the 1-5% or whatever that range is, and it *****. What I do agree with is that the company should compensate accordingly when things break while the product is under warranty.

I also had the same issue. I searched high and low to find the sollution, and i thought maybe i could be a hardware problem.. but then i ran Color Sync with the tool "verify".. And it found 2 software problems..

The file is locked. Could not be fixed.

This problem cannot be fixed unless you change the files rights and sharing.

If you locate those icc-files, right click on them, and choose "show info" you can change the rights on the specified files. Change them all to "read and write". Do this on both files. Then run "Repair" in Color Sync.

This fixed the problem for me (no flickering for 30 minutes, before i did this the screen flickered every 2 minutes)..

Remember to change back to "read only" in both files..

Hope this will fix your issue!"

Thanks for sharing this. I repaired the files and the flickering on my 2012 Macbook Pro 13 Retina has disappeared.
