Q: Macbook pro retina flicker

I got the same problem   Can you tells me if the screen remplacement really works ? Or just for a couple of time ?

Also, do you try to start on Safe Mode ? Because the computer become really slow with me

After they replaced the computer, everything works well. No flicker not thing horizontal lines when using HD 4000 intel graphic card. 

I got my MBPr 4 months ago, but I will try to have a new one.  I leave really far from an Apple store, it should cost me 120$ for the shipping. If Apple don't want to pay, they will be oblige to remplace it by a new one

I do the color sync trick (just verify-repeair) and I don't get the problem 2 day after. Do you think it will come back ?

Just chiming in, I have the flickering as well.

Have tried repairing color profiles, resetting SMC, PRAM. Nothing helps. Definitely seems hardware related, I've seen this in Windows as well.

I remember the first intel-MBP I had got a burned GPU — the screen just went black, but the computer still worked. Apple did a free repair for all those affected outside the warranty. Could this turn out to be something similar, if it's happening to a lot of computers?

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 .
