Q: OSX Lion + 2011 iMac 27'' + Video = Freeze

Hello.

 

Got a brand new 27'' iMac, installed Lion. The machine freezes randomly when starting to play videos, either on Youtube, Quicktime, iTunes.

 

When it freezes, the mouse still works, but the machine doesn't respond to any command, requiring me to hit the power button and restart the computer.

 

Searched on kernel.log and system.log, and found no crash/error/message.

 

Anyone suffering from the same problem? The machine is pretty solid, been running some OpenCL kernels too and they are ok. It's only video decoding (possible on the GPU) that seems to freeze randomly.

iMac, Mac OS X (10.7)

    @joeygillis  Yes, Thanks. At least this is a positive step to pursue. I'll take it, even that given a past effort at the Genius Bar at an Apple Store didn't work out for me. Things were starting to get a little too negatively cyncial on this and some threads -- though I certainly can understand why.

     

    It certainly can't hurt to have the diagnostic test at the genius bar--at least you will learn where your mac stands with that. But, when I went to the  Genius Bar, they did the test (It is a type of hardware stress test of your machine) and my machine passed with flying colors. I can also say that after that test, my mac performed fairly well for a few days.  . . . then back to the old routine . . .

     

    I will contact them tomorrow.

     

    I hope you will keep contact here to let all know how you fare.

    Already been done multiple times. I don't think it does anything to be honest with you. If Apple knew what the issue was, they would fix it; I don't think they have an idea as it is hardware related. Plus, walk into any given Apple Store, go up to any iMac and try to recreate the crashes. You can and those iMacs are ghost images every morning as a clean install. They don't even care to hide that fact the iMac has issues. Show the geniuses, which aren't, and they will act like its no big deal, that it happens on every computer. It's a joke, one big joke man. I tried to stay positive but I just gave up; sadly this is no solution or help to be offered.

    To whomever at Apple reads this thread,

     

    I will not add more to the general miscontent about the iMac/Lion issue.

    But just for you to know, I am one more fellow among the angry crowd. I am using Apple personal computers since 1984, I have worked on almost every Mac Apple has put on the market since that date. Last October I bought the new iMac 27 full features with Thunderbolt (that was the catch) leaving my former iMac working like a bliss under SL.

    Today, after fighting so long to make Lion work correctly since it's release (dropping extensions I needed, spending hours reading, scrutinizing the console logs etc), I am back to SL. What a liberation ! I spent the day recovering the needed apps, redownloading the SL versions for those needed, but what a release not to restart every now and then (with 10.7.3 increasing the problems it seems) not losing the work developped for 20 or 30mn. When you are in the creative realm, a lot can happen in 10mn. When it's lost, it's a good incentive to come up with something new, but today, as I have a time frame to respect, I am tired and I give up. I give up the re-creating, the "think different" reconducted. 

    But unless you do something about this issue guys, people will really start to think differently about Apple.

     

    Thanks for the attention.

    thevzitor: Very well put, I was under Apple Care since June 2011 for my iMac, in August/September/October and November 4 months of h e l l of loosing data and constant freezes and hardware failures I had enough. When my local Apple Store called me in Nov. and told me my new iMac was undrepairable I was relieved, basically told me they reloaded my credit on a nice shinny new Apple card and said buy whatever you want. Well, I wanted another iMac decked out machine with speed and grace, but I did not want any headaches or to deal with this BS anymore so I settled for a decent Mac Mini loaded and a new Apple Display and even picked up my wife a new Macbook Pro. Well so far zero issues, but I make sure no updates get loaded on for now till they get this sorted out, this has gone on way too long and I know people that are waiting to get a new Mac but they will most likely pick up a PC because they don't want to deal with this. Apple needs to get a new software version out soon and disregard Lion(Vista) and come up with some thing that was rock solid as Lepoard, which I greatly miss.  I think I might even look for used Machines that don't have Lion on them if they don't get this fixed soon.

    the viztor:  kudos . .. well said; and your words capture very well the sentiment, emotions and feelings of many of us.  Further, as ardent Apple devotees, to some very great extent, we are beginning to wonder whether we might have even been somehow betrayed and forgotten.

     

    I would venture to say to you also that I have had simlar trouble in SL 10.6.8, less frequently in 10.6.7,and  rarely in 10.6.6. I record no problems in 10.6.5 and earlier. And, since others have recently mentioned it, I also have had no problems whatsoever in the Leopard 10.5 series.

    I understand everyone's frustration.  Like I said, Apple does not have an answer right now.  However, if a solution becomes immediately available and you have logged your complaint with them, they will be able to inform you directly.  It also allows you to rule out hardware issues if you haven't gone to Genius already.  Whether you go or not is your business, but making a complaint with Apple is still important because it forces them to recognize the complaint (as opposed to ignoring it here) and pay attention to how many people actually have a problem.

     

    As it is, I got fed up before and decided to boot into Snow Leopard.  It's taken a while but I've started to degrade performance here as well.  I installed Firefox but didn't import anything from the other partition.  I was playing a flash game in Facebook which started to tie things up.  I don't know if it's the video itself, or the number of tabs open in Firefox, or iTunes, or what.  But I'm honestly only running FF with a few tabs open, one of which is a game, YouTube, Twitter app, iTunes (open but not playing anything), and Yahoo messenger.  On a clean Snow Leopard.  That never behaved like this before.

    Well I thought I was in the clear after a couple of weeks since getting my iMac back from Apple (see my post page 101).  FVD: my stress test passed as well and everything worked flawlessly...until tonight.

     

    I see that there are 2 updates available (Airport Utility 6.0 and OS X Combined 10.7.3).  I'm afraid to introduce any new variables at this point.  My iMac wasn't doing anything but it was in sleep mode for a couple of hours.  I came back and launched a game and within a few minutes the screen blacked out.  Hard shutdown.  Started back up again and before I even got the chance to launch anything, the screen went flickering with gray screen and vertical stripes.  Ugh!!

     

    I am now back in it and it hasn't freaked out yet so I'm quickly posting to this thread before I lose it again.  From past experience, once it occurs it is now in full terror mode and will shut/kill/spaz out my screen at any give point!!  I don't live near near an Apple store so I have to travel a long ways to see support again and I'm sure they'll stress test this thing and come out flawless and I'll be hauling it home again.  *** seriously!  I got AppleCare but calling them will just waste an hour of my time because I already know their full routine.

    Rentu: I had Apple Care on my June 2011 iMac, I played that cat and mouse game with them for 4 months and finally said enough of this BS, you guys know there is some thing going on with the software that is causing hardware issues, if you can't repair it correctly then give me instore credit, so far no issues with my Mac Mini but I "Refuse" to update it. I will not do the 10.7.3 as I have read it causes more issues then what it is worth, I feel like I am in Vistaland all over again. Best to luck, tell them to talk to a senior customer care rep, and tell them you want a replacement or credit!

    I can't even get the imac to boot anymore. White screen and sits there at least 5 minutes. On hold with Apple right now waiting for Sr. tech. This is crazy. I had the whole imac unplugged from power and devices for 30 min to go shower. Now I have a brick.

    Typing this on iphone. Apple disconnected the call. Fantastic. They took my callback # so hopefully they call back. I got a life to get back to.

    Spent the last 2 hours troubleshooting. Got nowhere of course. IMac is even crashing during login screen. Spent the entire time working with support and them pointing fingers at software, games, peripherals and I am not getting the black screen of death before I even do a thing. Guess I won't be working from home tomorrow.

    Rentu: The exact thing happen to my iMac down to a tee, I would demand a new unit or better yet to save yourself "time and money" get some thing else. I had the most decked out iMac you could buy, the computer was lightning fast after SL latest updates and then when I went to Lion, my computer became a Brick. I took mine in 3 times with several hardware failures over a 3 week period, I finally said to Apple give me some thing that works that isn't an iMac right now.  I am still p i s s e d as I really could use a Quad Core i7 with a much better video card, but for now my Mac Mini Dual Core i7 will have to do. Some thing isn't working right with Lion and there hardware with the iMac, ironically so far my Macbook Pro and Mac Mini seem fine with Lion so far.

    Hey folks... Been out of town for family emergency... <.sigh..>.

     

    I see nothing has changed.  Surprise.

     

    Joey, I couldn't even open up my application folder before a freeze/crash.  Went back to Leopard.  When and if Apple

    Decides to stop making software for my iMac, I'll decide then if I stay with Mac, or do something different.  I'm done.  Right now I've got to get back to work.  It's been over 3 months of hel l. 

     

    I have registered my issue with Apple.. And I'm glad I did!!  They hadn't heard of any issues with Lion or and updates.

    I'm sure they'll get right on it!

    2rodee,

     

    I am sure Apple is aware of this issue as it is spreading like Cancer. Total BS as I dealt with it for 3 months, lost a bunch of data trying to do a forced backup on Time Machine.  Very hard to do when your machine keeps on shutting down and freezing up.  I registerd my issues a few months ago, there are plenty of other threads on here with very similar issues. I wish I could go to Lepoard with my new Mac Mini, I was told I can't, if they don't get this fixed I will look for a used machine with Leopard on it.
