Screen froze, purple lines, three beeps. Help!

I was using my computer to watch a movie, when suddenly it froze and purple lines appeared on the screen. The purple lines seemed to glitch, and the sound of the movie sounded like a broken record. In a panic, I held the power button to turn it off. The screen went black, but the fan was still going, and the computer was emitting three beeps. I held the power button again, and it finally completely shut down. I did some research, and it says the three beeps are a problem with the memory, but what about the lines? What does that mean?

MacBook Pro (13-inch Mid 2012), OS X Mountain Lion (10.8.5)

****LONG TERM SOLUTION*****.


Hi everyone. I also am having these exact problems. Just for everyone's benefit, here are links to all other threads I can find with people who are also experiencing the same problems. It seems to me this is a fault that is present in many Mid 2012 macbook pros.User uploaded file

Macbook Pro screen glitches, 3 beeps, NOT THE RAM

Field of vertical lines all over Macbook Pro screen? (+ freezes, beeps)

Macbook Pro purple lines on screen?

Macbook Pro display glitches and laptop freezes

Re: Screen froze, purple lines, three beeps. Help!


I have a Mid 2012 MacBook pro and experience all of the same issues as described on all of these threads.

  • laptop will randomly freeze
  • glitches then appear on the screen, mouse stops moving, keyboard is unresponsive
  • the laptop then shuts down and won't turn on again
  • it then starts beeping 3 times while the screen remains black. I have to hold down the power button to stop the beeping
  • sometimes, after the screen freezing and glitching, it will restart
  • some days it will only happen once, other days it will literally happen 6 or 7 times
  • can happen while watching videos, just browsing on safari or it can happen while still on my home screen. It is completely random.
  • I have run system diagnostics, i have wiped the laptop and reinstalled the Operating system, I have brought it to an apple technician who didn't know what is wrong with it. I have wasted hours on the phone to apple support who have just said its out of warranty and they can't cover the costs even though I have told them that this seems to be a manufacturers fault.


The bottom line is, I bought this MB just over two years and spent a lot of money on it, I have taken perfect care of it, never dropped it or spilled anything on it and it is always kept in a protective bag. It therefore is completely unacceptable that I should be experiencing these issues with one of the most highly regarded brands around. It's not good enough and we should not have to incur costs to repair these faulty laptops.


***SO, THE LONG TERM SOLUTION***

I went to the genius bar today and had a chat with a very helpful individual who told me that apple will not recall or release a 'repro' on a line of products based on what people say on forums. Apple will only cover the costs and accept fault if they see that there is enough people experiencing the same issues on the same line of products. She said that we need to go to http://www.apple.com/feedback/ and fill out tis feedback form. If enough peole do it, Apple will see that this indeed is a fault with 2012 MacBooks!

This means they will cover the cost of people who are experiencing these problems!

I know it's not an immediate solution, but it seems to be the only way Apple will realise and hopefully the, accept the fault.

I Got the same identical problem, now my computer is in the Apple Store, trying to understand what happened,

maybe be for them is the logic board that is dying, and I ve to pay more than 500€ to mount a new one, and I don't have all these money, and I dont wanna pay for something that is not my fault.

like u suggested I send a fedback telling them the problem and I hope they start to rapair for free, because these problem happen more often on retina and they repair the reTina for free, cause they ammitted that there is an issue with the mbp.

what make me very angry is that a genius in the Apple store show me a list of computer with the same issue and there was like two model before mine (MBP mid 2012 15") and three after, one of them was a retina of the same generation. If your computer is in this list they repair it for free, I found ridiculous that the same problem of all these generations, miss one of it. There is a problem In the mBp and they have to fix it.

I'm an apple user from 7 years and I never had a problem like this.

ill switch to other brand, cause theyre starting to make bad computer, is not like before.


I'm really sorry for the bad English, but I'm not a native speakeR.

Hi :

The problem davidh_10 have described is identical to what I am experiencing with my Macbook Pro 13' from Mid 2012. You are absolutely right there is something under the left Command key and when I lift the machine from that side I see the vertical lines followed by keyboard freeze and a crash. I have always used the machine with great care and never dropped or spilled anything.

As you suggested I will fill the feedback form as well to see if Apple can help us.


Here is my screenshot -

I also have the same model (Mid-2012 13" MBP) and the same issue. Mine first happened 8 months after purchase, and they replaced the Logic Board and hard drive. Then 10 months after the first repair, the same problem occurred so they replaced the Logic Board and RAM. That didn't fix it either because 13 months later the same problem is happening. With two new Logic Boards, a new hard drive AND new RAM, obviously there is something clearly wrong with the actual manufacturing of this model rather than the individual parts. I would not bother paying $280 to replace/fix anything for the laptop as the problem will probably persist again eventually.

Hi. I was experiencing this problem after I upgrade my Mac OS X to Yosemite.

I went through all those symptoms and managed to get rid of it by downgrading Yosemite to Mountain Lion (this was my original OS when I bought my MBP).


To downgrade, wipe out all your hard drive - including the Recovery Partition. You cannot downgrade if you still have a Recovery Partition.


I am willing to upgrade to Mavericks next week and see if the problems still occurring.
