Monitor is flickering after upgrading to Mavericks

Hi Gabriele

I have a macbook pro 13" mid 2012 i7 2,9HGz 8GB.

I'm having the same vibrations/flickerings on both internal and external monitor. When a come onto the dock or leave it, it flickers. When I open a screen that was in the dock eg safari, it twists open like before, but with flickerings while doing it.

Kind regards

Bart

Hi Gabriele,

I have exactly the same issue with iMac (no external monitor): flicker when I move the mouse over the dock, when I move the cursor over a Safari webpage, when I scroll.... I guess it must be something related to the graphics card... I also have more issues (crashes and no sound), so I hope Apple would find a fix for it quite soon.

Regards,

Mugabi.

Just upgraded to Mavericks now on my mid 2012 15" Retina MBP and am having the exact problems that you are describing 😟

same here - flickering takes place in the dock area mostly, not only when scrolling, but also when moving windows or viewing a video - here's one where you see this errro: http://www.youtube.com/watch?v=-nNPUizjz2Y&feature=youtu.be

Iv upgraded to maverick and not at all happy... first off my thunderbolt does not work any more....

And now the apple monitor im using with my laptop (macbook pro I7 2.2ghz / 8gb ram / AMD Radeon HD 6750M 512 MB) via mini dvi flash's to a black screen every now and then...

Im not sure about the monitor flickers you guys are getting? Im literally getting the monitor display a black screen as if the apple screen is switching off and on again because of loss of signal?

Really anoying when trying to right code and design!

APPLE FIX THIS PLEASE! before i download adobe suite for my windows 8 partition!! and yes i just said that! >_<

I also have the issue of external Apple display randomly going black for a second or two. MacBook Pro 2.2 GHz i7 via thunderbolt to Apple 27" external display.

Same issues here: Mac Air Mid 2013. Flickering in Chrome, Safari and every other application; dock Flickering and very slow mission control animation. I'm afraid there's something wrong with the graphic card.
I was scared after my Mac became very hot yesterday after I put it in stop status but I see thos flickering problems are common issues...

Same Issues!

After having upgraded my OS to Mac's new Maverick OS, I noticed flickering in Google Chrome Browser and in my dock. These bugs must be fixed but i dont know how. Help needed!

Same here. It is obviously a general problem. Extremely irritating.

The flickering is in columns of horizontal black bars covering all or part of the screen and is continuous.

I use SwitchResX to get the correct resolution of the external monitor. I thought it may be that so I uninstalled it but no difference. I have repaired permissions, run DiskWarrior, reset the PRAM, etc. etc.

I have a Henge dock which in one go connects my MacBook pro to the external monitor and to my desktop G4 Mac, router, power supply, USB scanner, printers, etc. I use a bluetooth mouse and keyboard and it makes life a lot easier when I am working at home. Looking back it appears that the same problem arose after previous upgrades of OSX so I assume that eventually Apple will get round to sorting it out. Until then I will just have to put up with the inconvenience of using the MacBook open on the desk and making any connections as needed.

I'm experiencing start up flickering using a Henge dock with an external monitor and bluetooth keyboard and mouse after upgrading to 10.9 last week. I find that I have to do a total restart to resolve the external monitor display flickering issue. Surprisingly if I invoke the screen saver mode it stops flickering but starts up again after I log back in if I don't do a restart. This is a very irritating issue that needs to get resolved soon.

Do you also have issues while watching videos? I noticed on my (Early 2013) rMBP flickers a lot while watching anything on Hulu, Netflix or YouTube.

I have found a cure to my flickering monitor problem. If I start up my MacBookPro completely before putting it in the dock - NO FLICKER!!!!

Previously I would turn it on and then insert it in the dock when the grey screen and the revolving cursor appeared. So my suggestion is do not plug into your external monitor until MacBook has fully booted up.

Terryap,

This does cure the flickering on startup issue-thank you! I have mixed results getting the monitor to come out of sleep mode sometimes but this works.

Yet another way to fix it (thus far)...

System Preferences > Energy Saver > Automatic graphics switching (Deselect the checkbox).

I have a MacBook Pro 15" Retina, running OS X 10.9, that is exactly 1 month old. As of today it began experiencing a flicker issue. The step above is from a 2011 post. It solved the problem after a shutdown and a 2 minute wait to start up again: https://discussions.apple.com/thread/3186094

Originally, my desktop screen would flicker about every 2-4 minutes. It's been 1 full hour and no flicker after working with a range of applications. However, just in case, there were a few other steps that I noted while attempting to fix the issue...

My initial reaction was that iCloud was the cause of the issue, and I decided to sign out and then quit Adobe Creative Cloud. I don't believe either made a difference—both have been reactivated since. I also ran Disk Utility > Repair Disk Permission, since there happened to be issues with permissions that I was unaware of.
