  • MiB4 Level 1 Level 1

    We purchased 8 17" macbook pro laptops hadn't noticed this issue, use wireless all the time. We had an issue with some of the laptops freezing after ended up being Time Machine and Sophos scanning the drive. But no Kernel Panics.


    Now we have 16 21.5" iMacs. 2 of them are Kernel Panicking with this exact same message. and those are the only two that had the wireless turned on. The one is at a secretary desk the other in a wired Lab. In the lab there isn't enough wired ports so the wireless is on, the other is the secretary turned on the wireless even though she is wired. these are the two that had kernel panics.


    so is this only with iMac? i read through the thread and it seemed only iMacs.

    worth noting that almost a month after turning WiFi off, my iMac is still kernel panic-free. But come on Apple, fix the driver!

  • MiB4 Level 1 Level 1

    So the iMac in the lab that was kernel panicking we hooked up to ethernet and turned off the wireless. It has not kerneled since. We turned on the wireless on another iMac in the lab that had been wired and never kernel panicked. it has kerneled since turning on the wireless.

    This is exactly how we have had to "fix" our kernel panics.  As long as the wireless is off then the machines work perfectly.  When the wireless is on it eventually panics.  I have had to do this on 20 machines, luckily none of them require wireless to get on the network.


    Apple has been less than helpful on this and from what I am seeing it is pretty wide spread.

    i was looking how to add our "voice" to apple. i clicked on a link earlier where someone suggested going but you have to be a developer. the only good news? i wasn't crazy on what was happening, others have had it also. this has been happening for a while according to this forum with the time stamp, i guess by now i'd have thought apple would have fixed this. we had macbook pros with lion that we purchased first and don't have this problem, so it looks like it's just with iMacs...strange, but thank goodness the laptops don't have the issue.

    I have a 2007 MacBook and as soon as I installed Lion 10.7.3 I started having random kernel panics.


    I spoke with Apple Support yesterday (they gave me a "Freebie" even though I bought Lion more than 90 days ago) and we went through the OS reinstall - still kernel panics.  Next step is supposed to be for me to make the 100-mile trek to Metaire, LA, and have an Apple Genius try to do a software isolation. 


    After following this forum thread I do not think I will do that.


    Tonight I am going to hook it up via ethernet cable and leave it to run all night - it has not managed to run more than a few hours without a kernal panic, so if it runs all night without crashing it further confirms that it is an Apple-created issue.


    Of course, now I find out that my Intel GMA 950 equipped MacBook will likely not be able to run OSX Mountain Lion.  Thanks, folks.

    Some issue with my iMac.... have kernel panics when using wifi.... i ran a 40 foot long ethernet cable through the house and since then no more have existed. it is annoying how it is these minute but important things that apple tends to overlook!

  • MiB4 Level 1 Level 1

    And with Mountain Lion coming out will they ever address it.

    has anyone applied the new WiFi patch just for grins? from the description:


    This update resolves an issue that may cause an iMac to not automatically connect to a known Wi-Fi network after waking from sleep. It is recommended for all iMac (Late 2009 or newer) users running 10.7.3.


    it doesn't seem like this will help, but I'm curious. I should point out that this thread,, doesn't give me much hope though. Anyway, I'm not applying this patch for now.

  • MiB4 Level 1 Level 1

    did that come thru the software update? then yes...  i think. when did the update come out? i don't have the imac it is in a school setting but i could go look at it. so i'm not always aware of when the new updates come out.

  • Lost In Austin Level 1 Level 1

    This update popped up on my iMac yesterday (24 Feb 2012), so it is very recent.

  • MiB4 Level 1 Level 1

    ok, then no i haven't . you are going to wait on it you said? i will too as it's in a lab wired now so it's not urgent but  i do hope they fix it, a secretary has one and she is wired but during enrollment in August she moves her computer and would need wireless then. the explanation for the update doesn't fit our problem anyway right? the sleep isn't an issue with this. students are doing work and it'll kernal. an i read an earlier post that replacing that system file with a snow leopard one fixes the issue but of course makes the Air Drop not work. so i would think it has to be tied to that capablity that Apple put in with air drop.


    now on our macbook pro's we had this issue: Mac OX X Lion freeze after wake-up once i had sophos ignore the time machine backups it no longer freezees on wakeup.


    and now they have moutain lion coming out...

  • MiB4 Level 1 Level 1

    on the other post you refered to the last 5 or so say the patch fixed their issue. still not sure it'll fix our kernal issue. it seems a different issue from ours but maybe it's related.

  • Jon Land Level 1 Level 1

    I'm having the same issue you all are on my two-month-old 27" iMac. I installed the update, and now I'm getting kernel panics more than before (about twice a day).

  • OliverSzondi Level 1 Level 1

    Ive been getting kernal panics since the latest Airport update for the system update... pretty annoying indeed!
