Macbook pro retina flicker

I can't right click the files. Can you explain a little more in depth please?

Sure. I just tried again and i have no issues with righ clicking. Maybe your trackpad is not set for right clicking or secondary clicking. Look in system preferences/trackpad/secondary click and check what gesture you have selected. Also make sure you are logged as the admisntrator.

1. Once you are able to right click the file, click on Get Info,
2. go to the bottom of the pop up screen
3. and in the area of sharing and permissions click on the padlock and then enter your admin password
4. ensure the three types of permission are set to 'read and write'
5. then run color utility and click on verify and then repair. then that should fix those files.
6. Dont forget to go back and change the settings as you found them.

This is the 5th day and have tested the laptop through and through and no flickeing. I hope this solves the issue for you too.

Good luck.

I have a late 2012 MBP Retina and I'm getting the flickering. It seems to affect the lower half of the screen and consists of brief displays of window title bars that should be at the top of the screen. I have changed the permissions on the files as described above, but I'm not hopeful about that. When the problem comes I can stop it by angling the screen back a bit further, or by pressing on the black plastic part of the hinge under the screen. It's got to be a cable pinch.

You're right and sadly Apple still as yet has not acknowledged the issue or done a recall for a widely known defect. I for one can't be without mine long enough to get it fixed. I'm sure others are in the same boat.

My Macbook Retina Pro 13" has started flickering and it was getting worse. I read the 12/15/2012 post by showerkv and oddly enough I had the exact same two files causing error messages. I followed the advice and was able to repair the files. It is early yet to be certain but the flickering that was happening every couple seconds has now completely stopped. I hope that this really fixes the problem in a permanent way. But at least for now... so far so good.

Thank you for the advice!

You are a genius. Thanks!!!! 😍

This seems to have worked for me as well.

Could you please explain to me how to locate the ability to change these files to be unlocked--I do not know how to change the files rights as the solution tells us to do. I have those same files and problems but I can't figure out how to change the rights/

anyone-- can you explain that to me?

thanks!

I've seen a couple of posts in the support community regarding this issue. I first noticed my display flickering on a very infrequent basis about 6-9 months ago. My MBP 15" is one of the first ones made - ordered it when it was released. Before that time, I never had any issues with display quality. In the last month or so, I've noticed a marked increase in the frequency of the display flickering. I'm in the military and currently deployed. So, my setup here is much different than at home. At home, it was connected to a TB display, as well as a bunch of other peripherals. Here, I only have it connected to an external HD.

I tried the above solution; however, the display is still flickering and seems to be getting progressivly worse. If you watch the flicker very closely, you will see a title bar pop up momentarily on the lower 1/3 of the screen - seems the flickering happens about every 2-3 seconds now.

If anyone has any other ideas and/or solutions, I would really appreciate it. My MBP is outside of the warranty period right now. I sure would be disappointed though if my $3K laptop craps out before it hits 15 months old. 😠

Someone earlier in this thread mentons WiFi as the source of the problem. I finally read carefully - and then started experimenting. What I soon noticed was that:

1. I only had flicker at home
2. I only had flicker when an active download was going on

I switched by home WiFi channel around and after a few tries, picked channel 1.

Flicker gone!!!! OMG - !

beren 🙂

Wow! I turned off the wifi and the flickering stopped.

Anyone know if Apple is going to address this fault? I'm unable to find a setting to mitigate this flickering with the display. I wonder why this has progressively gotten worse?

My computer is outside the original warranty period of course...not sure if there is anything they could do to fix it anyway.

I had this problem a while ago, and I brought it into the Apple Store. They just reset the clamshell. It has to do with a wire being pinched, you really need to ask for the best person at this because its very easy to pinch. Anyway... they will most likely do a recall in 3-5 years on our model. It's a flaw in the design of the clamshell and body. But it's nothing more than that, very simple fix but could take a couple tries.

I haven't had flickering in 10 months since the fix.

Thanks for the help, I'll give them a call and see what they can do for me. I'm currently overseas on a military deployment, so it should be interesting.

Try the wifi fix first.

Hey everyone,

I updated to Mavericks and the flicker completely stopped. I can't explain why it returned in Mountain Lion, but if you're having trouble, try that as a fix.
