Mavericks Screen Flicker Fix

At some point during my software updates and installs last week, I managed to get the video system on my MacBook Pro Mid-2014  to “get wonky”.   That is a technical term, in case you are wondering.

“get wonky” – the point when something stops working correctly but is still almost functional.   AKA “FUBAR Light”.

The issue only appeared on my external monitors on the displayport connections.   The HDMI external monitor never had the flicker or “ants” issue.

After a couple of quick chat sessions with Apple Support the problem was resolved.   I’m not sure what the source of the problem was but it was definitely software related.  The software tests had passed and the problem did not exists for the first 48 hours that I owned the laptop.

I am fairly certain an SMC reset on the MacBook fixed the issue, but the 3 steps that were performed to get there are listed below.  Hopefully this helps with your Mavericks video issues including both flicker (screen goes black as if turned off then back on) and “ants”, which apparently is  Mac-community term for video pixelation artifacts that appear briefly as horizontal or vertical bars that quickly appear and disappear at random intervals.   If you squint a bit while looking at your screen I guess it does sort of look like ants marching down the screen.  Drinking a fifth of vodka before doing the squinty-eye technical assessment helps as well.

Here are the steps I used to fix my Mavericks video issue on the MacBook Pro:

Reset Pram

Shut down the laptop.

Power on the laptop.

IMMEDIATELY press and hold the following keys, you must do this before the first gray screen appears:

Option + Command (⌘) + P + R

Reset SMC

On the  MacBook Pro Mid-2014 running Mavericks you reset the SMC by holding down these keys ON THE LAPTOP (not a USB keyboard) simultaneously for approximately 5 seconds:

Left-Shift + Control + Opt + Power Button

Login / Full Shutdown

When I powered on the laptop after doing these steps the video issue appeared to be WORSE.

Log in to your main admin user account, then shut down.

On reboot my problem was fixed.

Hopefully yours will be too.

MacBook Honeymoon Over, Apple Still Shines

Welcome To Apple Support

Day 4 of being a new Mac user and so far it is going well, considering.

My Hidden Talent

For people that don’t know me very well my “hidden talent” is the ability to break ANYTHING related to technology  with astounding efficiency.   All of my seasoned developers at the software consulting business I ran a few years back knew it well.    Whenever someone felt their project was ready for the customer one of my lead tech guys would say “let Lance play with it, if he doesn’t break it in less than 3 minutes you are close”.     Suffice to say that I don’t recall a single project that passed “the Lance test” on the first go.  Or second for that matter.

My favorite anecdote and my crowning achievement to date was breaking a regular ATM machine, and I’m not talking a 30-year old one build on Windows ME but a modern nearly-new ATM, within 30 seconds.  Pull up to the drive-up ATM, put in card, withdraw…wait…no… check balance (while withdraw screen is rendering)… POOF… system crash.   A BSOD on an ATM machine.  Sweet!

Sad Technology
Windows 8 Frowney-Face. Yup, that about sums it up.

I give that background because it applies to my MacBook experience for a few reasons.  First, I have become VERY familiar with technical support lines with every type and size of technology company on the planet.    Second, I have  also learned that there is NO technology I cannot break, even without trying, no matter how solid the platform may be.    My high-end HP laptop, less than 24 hours.   My teched-out 2014 BMW?  Less than 6 hours.    If something lasts more than a day under my full-fledge “run this thing at full throttle abuse” that is impressive.

Macs Are Not Lance-Proof

My MacBook Pro?   Lasted just over 48 hours.   That is somewhat impressive given the fact that I want from vanilla MacBook Pro setup to upgrading the packages software, adding proprietary Logitech unity wireless drivers, proprietary Wacom table wireless drivers, 3 external monitors on 2 display port adapters and a HDMI connection, a 5-year old inkjet, added a pro backup service, 3 virtual box machines, a security dongle, an Android phone, and installed several developer-heavy software packages in that time.     The MacBook survived all of that, ALMOST.

It Worked Great, At First

The AMAZING part is all that stuff worked exactly as I expected with minimal fuss.    Getting 3 external monitors (2 display port and 1 HDMI) on an HP notebook with a docking station SPECIFICALLY DESIGNED to run “5 monitors (sales lie, it really can only do 3)” took over a month including a BIOS update, video driver update, and 3 days of level 2 technical support on how to configure and hook everything up.   MacBook?  Plugin in all 3 monitors and BOOM… they are all up and running including a FOURTH if you included the laptop display.  Sweet.

Adding the 4-port USB monitor hub on these HP monitors to the MacBook?  No problem?   Cascade them with monitor 1 USB into monitor 2 into monitor 3?   No problem.   It shouldn’t be.  USB buses, when powered like these HP monitors are, should be able to daisy chain up to 128 units on a single USB chain.      With the HP?   It rarely could find devices on the first 4-port monitor hub.   Daisy chain them?  NO WAY.  NOTHING would be found and the system would crash corrupting files along the way.   The MacBook handled it with aplomb and to put the icing on the cake it recognized a 5-year old inkjet printer, installed it with the right drivers, and was printing through the 3rd hub on the 3rd external monitor in less than 30 seconds after connection.    Under Windows it was a bitch just to get the thing to print in under 10 minutes and only with a direct printer-to-laptop USB connection. Anything else was futile.

Overall I am impressed.

Breaking A MacBook Pro

But I DID break the MacBook Pro.

Somewhere along the way one of the software updates or installs (I’m fairly certain it is software related) caused my external monitors connected to the display port connects on the MacBook started to “flicker”.   By flicker I mean go completely black for 1 or 2 seconds then turn back on.  Sometimes this would happen once every hour.   Sometimes it would happen once every 5 seconds for 5 minutes straight.       When that didn’t happen I got what the Apple community has coined as “video ants”.   “Ants” are horizontal or vertical bands of pixel artifacts that are similar to “snow” you would find on analog TV years ago (for the young kids that don’t know what analog TV or “snow” is, go look it up… I’m sure YouTube has a video).     Needless to say, these issues made it impossible to use my external monitors and get anything accomplished.

Apple’s Stellar Support

What I found was that Apple Support, thus far, outshines Microsoft and just about EVERY vendor in the Microsoft-centric hardware space that I have ever used.    I’ve purchased top-of-the-line equipment from Sony, Dell, Toshiba, HP, Asus, Acer, and Lenovo.   Few can compare to the general engineering finesse of Apple but NONE can come anywhere CLOSE to Apple in regards to customer service.   NOT EVEN THE SAME PLANET.

I did some homework and tried various online remedies.  Nothing worked.    I decided to take advantage of Apple Support that comes FREE for the first 90 days with any Apple computer purchase.     I got online and opened a chat session.     This is where Apple starts to blow away the rest of the market when it comes to support.    Just getting started with support was painless.      Because I took literally 30 seconds to sign up for an Apple ID when booting my laptop I only had to enter my email and password for that ID and Apple could start building my support case.

It only took a minute and involved 3 simple questions before I had someone on  live chat.   The questions start with “your Apple serial number”.   This is easily found from an on-screen menu in the OS.  No flipper over the laptop, or looking under a desk at the back of a tower, or rebooting to the BIOS.  Just go to the main menu and look at System Preference/More Info.   There it is plain as day.  Now THAT is an novel idea… ANYONE in the Windows world paying attention?   The other questions? Your name and a brief description of your problem.

Support Personnel Using English?

So I have someone on chat.  Guess what?   They actually READ AND WRITE PERFECT ENGLISH.  Holy cow, does Apple actually employ Americans for support?    Maybe.    If not they do a GREAT job training people how to communicate in perfect English for the American users like myself.    Not that I’m a xenophobe but I just cannot stand reading blatantly horrid streams of grammatical and syntactically incorrect English for an entire 20 minute chat session.     I cannot tell you how refreshing it is to not be reading or listening to “Yoda-speak”.   I had ENOUGH of that with Microsoft premium customer support for their cloud services last night.   “If you press now please button on computer” or “Hold now down the control button, you shall.”   Really?

And Can Use Their Brain?

Guess what else?  They are ALLOWED TO USE THEIR BRAIN!   They actually are REAL PEOPLE WITH A REAL BRAIN.   I just about had a God-damned heart attack when they literally said “Can you tell me what debugging you’ve already done?  I don’t want to ask you to do things you tried already.  Your time is too valuable to be wasted.”.     HOLY FRIGGING CRAP… YOU CANNOT BE SERIOUS!  That is NOT how customer support works in 2014.   APPLE…  do you realize you are completely screwing with the customer support paradigm?   This cannot possibly be good for business!!!     That one simple interaction, that has now happened not with ONE but with TWO Apple support people in a row is one HUGE reason why I don’t think I’ll ever stray from Apple from this point forward.  Not unless they decide to be just like everyone else on the planet and go to a 100% check-the-box-while-reading-the-script support model.

I told them all the steps I had taken from swapping cables, ordering new cables, swapping monitors, uninstalling software, reboots, swapping ports, and a myriad of other options.     They read it all, and actually came up with some things I DID NOT TRY.     They did so nearly instantaneously.  Like they actually knew what the hell they were talking about.       Yes, they did have me reset PRAM which did not help.      They also had me reset SMC and run the Apple Hardware Test (AHT) which did not show any errors.      MAYBE the SMC reset did help, though at first I was not convinced because the login screen immediately showed screen flicker, but I will tell you that as soon as I powered off all 3 monitors, turned them back on after trying one more cable swap trick THE MONITORS WORKED.

What is not most impressive is the fact that my monitors are now working again as expected but the fact that I was not asked a bunch of dumb-ass questions or told to “did you reboot”, “did you power off for 30 seconds”, or other obvious options.     They could tell I know a little something about computers and went STRAIGHT to the uber-technical stuff.    They came up with some new analysis and debugging steps nearly immediately.    I was truly impressed.

Just as impressive was the team communication.     After my first contact with Apple Support I was told “this is your support ID in case you need to call back so the next person can pick up where I left off”.   True enough, the next support person after my system reboot and PRAM reset did not work picked up EXACTLY where he first person left off.     That person never needed to ask for my case ID, they looked at the history and said “is this related to the monitor issue”.  Yes.   Moving on to the next item.       That is how support should be.

Hey World – Copy This!

In my book, Apple knocked it out-of-the-park when it comes to technical support.  Why?

  • 30 seconds with a FEW simple questions to get registered for online support.
  • No more than a 2 minute wait for a LIVE support person.
  • Support people are ALLOWED TO THINK, they are not script-driven.
  • Support had a CLUE even with a less-common problem.
  • Support ALWAYS made me feel like they WANTED me to use the service.
  • Every support person said “please let us know if this doesn’t fix it, we want you to be 100% happy with you Apple experience and won’t stop working on this until you are”.
  • They actually UNDERSTOOD the problem and came up with what appears to be the right solution.

Not This!

After a month of dealing with Asurion to get my HTC phone fixed and an entire evening with Microsoft Azure support  I am absolutely blown-away by the fact that Apple has real old-fashioned technical support.

Asurion?  100% script based to the point of absurdity. “I just did a factory reset an hour before calling you, it didn’t help.   them: That doesn’t matter sir, if you DO NOT do a factory reset now I cannot help you.   If we don’t see the phone re-register we will not proceed.  me: Can you see it re-registered 90 minutes ago?   them: sir that is irrelevant, if you don’t do it again now while I am on the phone I cannot help you.”

Microsoft? 4 techs, 3 time zones and at least one guy that my disk failure problem was related to an IP address change (WTF, really?) Don’t forget this guy too: “I am not an expert in that area, I will refer you to someone that is” from the guy that I was originally referred to as an expert in that area.

Apple Fan Boy?

A month ago I thought Apple users where just zealots that had buried their heads in the sand and ignored the myriad of problems that come up on their devices.      I used to think “well they are not overly technical and just don’t push the systems like I do”, but that notion was dispelled a few years back as some of the uber-geeks I know were also raging Apple fans.      Now I’m getting a taste of the Kool-Aid.    If this support experience is any indication of what it is like being an Apple Fan Boy, I’m all in.

And just as I finish writing this… the first monitor flicker on my display port devices in over 3 hours.  Maybe this is not 100% fixed so we’ll see just how deep the Apple Kool-Aid Punch Bowl is.    But wait, it looks like it was the VirtualBox guest going into and out of sleep state while in full screen on my other monitors.    Very like just a VirtualBox bug not an OS/X or MacBook hardware issue after all.
