OS X :: Macbook Having Kernel Panics And Dropping Wireless Connection?
Sep 4, 2009
I'm running OS X version 10.4.11 (Tiger). It's a 13" Macbook, two years old, from August 2007. I've recently been having a bunch of problems with it.
First, it drops its wireless connection a lot. Most of the time this happens while I'm playing World of Warcraft, but I've seen it happen even when I'm not. Everyone else connected to the wireless will have absolutely no problem with it, but my Airport icon in the upper righthand corner of my screen will go grey and then connect again, then go grey, connect, etc. I also experience a lot of latency in my connection when others don't (example with WoW... someone else will have 98ms latency, and mine will shoot up to 2500ms or so). Most of the time when this happens my entire computer seizes up. My game skips, my iTunes skips, my mouse skips or won't even move, I can't type or click, etc. Additionally, I've had it happen even when I'm connected to the internet with an ethernet cable with Airport turned off, and my internet connection will die completely until I restart my computer.
I've had problems with this computer in the past as well. About two months after I bought it, it wouldn't boot up and I had to reinstall the operating system. Then a year after I bought it, my motherboard crashed, and they couldn't really tell me why it might've happened.
Second, I've had two kernel panics in the past two months. The first one was July 18th, 2009, and the second one happened just about half an hour ago today (Sept 4th). The panic.log is as follows (both dates are included):
Is there something wrong with my computer?? Some special update that I don't know about?? this is so annoying!! I'm running Leopard 10.5.8 but this happened also on 10.5.7 and I am using an early macbook pro model - about 3 years old. I will be connected to the wireless fine all day then like right now it drops the signal and i have to hook my computer up to an ethernet cable. I can restart modem, router, and computer but I haven't found a solution except to try again in a couple of hours and it will work fine. I know it's a problem with the computer itself and my apple care just expired so i hope it's not a hardware issue. Anyone know anything? I've tried changing the password protection on the router but still same result. Just pissed off that my $3000 computer can't hold a wireless signal.
I have a MacBook Pro running OS X (10.6.8) and I have a Netgear DGN1000 wireless modem router. My laptop wireless connection keeps dropping out lately but the internet connection itself is okay - my provider tested and no dropouts show up so it is just the wireless connect from my laptop thats dropping out.
Two days ago I got a 'new' refurbished 13" MBP from Apple to replace my aging 2006 MB. It's ok, but not quite as nice as I expected. One major thing I've noticed is that the wireless reception is much worse than my old MacBook. They're both connected to a Netgear WGR614 v9, but the MB is getting about 2/4 bars, while the MBP is constantly dropping the connection. In fact, right now I have the MB booted in Win7 and it's running Connectify, in order to share the connection with the MBP. I'm downloading the latest software updates right now, and then I'll see if any firmware is available, but I doubt that will make much of a difference. Is this because the new MBP is made from aluminum?
I just bought a MBP 13 inch in August '09 and Ive been experiencing consistent dropped internet connections wherever I go. I'm in college right now, and I have wireless internet at my dorm and my connection keeps dropping randomly and the only way I can reconnect is by turning on and off Airport. I just went home today and Im experiencing the same scenario with my Home Wireless Network connection. Anyone know whats going on or how I can fix this?
My iMac has been connected wirelessly to my D-Link DI-604 802.11g router for near 4 months now.
About 3 days ago, the iMac started to exhibit strange problems.
Every 3-4 minutes, the connection drops.
The airport icon at the top shows full bars (and the router is about 2 feet from the iMac) but the internet does not work anymore.
Also, if I deconnect and try to reconnect, at first it gives me an error ("there was an error connecting to network XXX"), then my network disappears from the list for 1-2minutes and then I can connect.
I think it has to do with an authentication problem but the password is correct etc.
After upgrading to Leopard my Mac Book Pro continuously drops the connection to our wireless connection. After many attempts the only method I found to correct the situation is to perform a restart. Before the OS upgrade the wireless connection worked perfectly.
I am connecting through a Linksys router with a Time Warner cable connection.
So the problem that I'm having is that at random times I lose connection. At the same time the PC-s that are connected to the same network have connection, plus the ISP said that everything seems to be fine on their side. So there seems to be an issue with the WiFi on the MB. It just loses the connection and can't find it for about a minute and some times it takes about 5 minutes for it to reconnect to the network. And the problem isn't limited to only one network, but actually happens in different networks. It started as a minor inconvenience, but now it's starting to really bug me. And it seems that I'm not even making it up: [URL]
im fairly new to macs and im loving my macbook pro i got a few months ago. Only issue that's been happening is the wireless connection seems to be dropping every once in a while. Its gotten to the point where its pretty annoying. I dont have any issues with my buffalo routerand im not far from it as well. Im running snow leopard 10.6.3. I will be in the middle of working so its not like the laptop is in sleep mode where i know the wireless will drop which is understandable. If you need any more inf please ask, i havent had issues with my old dell and the same wireless router. Oh, after the connection drops, it will scan and find it(the router), then ask me to put my password in again, thats about it.
I have a three month old unibody MacBook, and up until yesterday, AirPort seemed to be working just fine, but over the past 15 hours or so, it has lost its wireless connection to the router four times. Two of the times, AirPort reconnected to the router on its own within a matter of seconds. One of the other times, AirPort said that it was enabled but not connected to any networks, and I had to manually reselect my router in the drop-down to reconnect. Now this morning, AirPort lost its connection to the router yet still showed that it was properly connected, but I couldn't access my network or the Internet at all. As soon as I disabled and re-enabled AirPort, everything was fine.
On top of this, I also got my first kernel panic yesterday for seemingly no reason while I was submitting a post to a forum, and I've submitted dozens of posts to that forum before without problem, so the forum can't be to blame. Normally one random disconnect from my router wouldn't be alarming, but four disconnects in the last 15 hours combined with a kernel panic that may or may not be related certainly has me searching for answers. I'm certainly quite confounded, especially considering that I haven't modified anything with my system, nor have I installed any programs in a long time. Should I be alarmed, or could this all be some coincidence?
I have had the Macbook air 11.6 for five weeks now and it has been rock solid except for a couple of kernel panics. Once when I first got it I got a kernel panic in Safari. I only use google browser now. I got a kernel panic two days ago. I went to open the lid and it did not come on. I found out there was a kernel panic. I am afraid if I take it to the genius bar they will have me reinstall the OS and add one app back at a time to see what is causing it but since they are so infrequent this is obviously not convenient. Also I have had my IMac 24 for three years and have tons more junk on it and have never got one panic.
I am currently planning to upgrade my 2gb RAM and I heard that my model supports up to 6GB of RAM, hence I am planning to upgrade to that size cause Aperture uses lots of memory and I use Aperture a lot. I am planning to get it from here: OWC 6GB PC5300 DDR2 667MHz DIMM Upgrade Kit. Everything is cool and all until I find out that some users are having kernel panics on OSX 10.6 with 6GB RAM (which is what I am using). It is now 10.6.3, so anyone care to report if it is safe to use 6GB or the problem still exist?
i have a 2.2GHZ intel core duo 2007 MBP, which once ran Tiger and is now running 10.6.3I had the graphic card break down associated with such models, and it was replaced thanks to the extended care plan-I originally had 1Gig of ram, but 1st got an extra 2Gb of danelec ram, and finally another 2GB- it ran fine for a year or so-then I started getting these kernel panics, which seem to be ram related-on tiger- I changed the HDD, switched to snow leopard, and they continue, they're apparently RAM related, yet what is odd is that they can be reproduced with any RAM combination involving 2 sticks- the original apple 1Gb + any of the two GB ram sticks, the 2GB ram sticks together-- it's all the same, the screen goes grey and i'm told to shut down the computer
with one ram stick it works, apprently avoiding the issue-i've moved the ram around, checked the slots, reset the PRAM,yet the issue is still there.now i know that I should be using paired ram, and will do so in the next coming months when I can afford it- yet what has happened to make the make the MBP seemingly refuse two sticks of RAM when it didn't before ?I'd also need to know that this is not a logicboard issue if it's possible- the logic board was changed due to the NVDIA bug, so it's a year old or so-I'm running it on the 2GB danelec as I type, no issue, the samsung ram works as well, and so does the 1GB apple ram, in any slot, yet two slots of ram causes the kernel panic crash- the area near the ram slot also seems to get very hot
Recently got my Retina MBP and love it, but have been getting quite a few kernal panics. Not sure why. I am suspecting Chrome Canary as the culprit but I never had any issues with it on my previous Macs. Here are two of the kernal panic logs:Â
Sun Jun 17 00:00:53 2012 panic(cpu 0 caller 0xffffff80002c4794): Kernel trap at 0xffffff7f823d57b1, type 14=page fault, registers: CR0: 0x0000000080010033, CR2: 0x0000000000000010, CR3: 0x000000005db1a03e, CR4: 0x00000000001606e0
I got a new macbook pro a week ago. The first time I shut the machine down it experienced a kernel panic right after I selected to shut down the computer. Programs randomly crash while I am using the computer. The apple store said that crashes are most likely due to CS3 because it was not properly updated for the system, so they installed the CS3 updates. The next time I used the machine after installing CS3 updates, it experienced another kernel panic upon shut down. I would like to hear about known issues with the Summer 09 macbooks. I am trying to determine if this is a hardware, software, or an OS issue.
I have a 2.2Ghz Macbook Pro 15" (2007) that suddenly can't get past the startup screen and ends up with a kernel panic and the You need to restart message. Happens 100% of the time now. I had Leopard on it when it started kernel panicking. I managed to boot from an external drive and installed Snow Leopard, but it started okay once or twice, then started having the kernel panics at startup again. Tried SMC reset, but no go.
I then tried going back to Tiger, thinking it might be a problem with the RAM. Tiger actually installed okay, and after it worked okay for a bit (2-3 times, maybe half an hour), I tried to install Leopard again. And got only kernel panics. And I can't install Tiger now either.
It occasionally starts up from an external disk that I use for installs (has Leopard and Snow Leopard on it), but that's not 100%. And I can't even get thru an install now. I started up with it in Firewire Disk mode, wiped the drive and cloned a system from my iMac, but even though it seemed to go okay, when I shut it all down and tried to restart the Macbook Pro, I got another kernel panic. Any ideas? I've switched 3-4 different RAM modules, and I don't think they're ALL bad. But no go. I've changed hard drives too.
Seems weird. I mean, it doesn't seem broken, as it starts up, goes thru the startup screen, seems to pause a bit and, instead of going to login, stops with a kernel panic. I assume it's HARDWARE, not software. But hardware problems are usually the RAM, sometimes the hard disk; and if the MBPro doesn't start up at all, then the logic board is probably fried. So what else can cause these kernel panics? A bad keyboard/trackpad (top case)? Bad PRAM battery?
Regarding the black screen issues, kernel panics and occasional freezings upon wake, I'm curious. After the EFI update I still had these problems (on an already replaced 11" from the apple store). But as soon as I uninstalled flash, they disappeared.. Anyone else with this apparently "rare" issue notice this?
I am running a Rev A Macbook Air. I performed a software update today on all of my Macs and only the Air is having problems. Nothing but Kernel panics telling me to restart. I tried booting into safe mode, single user mode, reset the PRAM, tried to reinstall via remote disk. I get nothing but Kernel panics.
recently I've been getting a lot of kernel panics. They usually happen at random times when I'm browsing Safari. Most of the time I can reboot normally but once I got 3 repeating beeps when trying to start-up.
This is from the problem report:

I have just now received my purchased 13.3 inch Macbook Pro model, with BTO 4Gigs RAM, and 250 HDD.
I opened the Macbook pro, and it worked just fine. First thing I did was to enable the WiFi, perform a software update, and update the system using Software Update with the combo update to Snow Leopard 10.6.2 (it was 10.6).
Immediately after performing the update and restarting, the computer crashed on startup 3-4 times, and still refuses to boot. It appears this is a kernel panic, with the first line saying "Panic Version mismatch between Kernel and CPU " and some other things like the version of the system and darwin, and the CPU model.
I booted from the DVD without problems, and performed a Disk Repair (which found no problems) and a repair permissions (which also found no errors).
Strange thing: When I selected the "startup disk" application I selected my internal HDD but it displayed 10.6 instead of the recently applied 10.6.2!!
Rebooting still crashes the computer, with the same kernel panic.
MacBook 2.1 Intel Core 2 Duo OSx 10.6.8 Snow Leopard
I've had my MacBook for almost 5 years, first Mac I ever purchased, and have told everybody since then how I've never had one single problem with it, virus, or anything. My desktop PC would crash about every 6 months prior to getting my MacBook & the employee at Best Buy talked me into getting a Mac. I've been extremely satisfied in every way with it until now.
I finally bought a mini-dvi to hdmi cord to hook up my 70' Sony Bravia as a secondary display, but ever since hooking it up I'm getting constant kernel panics where I'm forced to restart my computer. This happens atleast 10 times a day and sometimes as much as every 10 minutes. It's not the TV as I have the same problem connecting to my 44' Philips TV. Am I just constrained to only using the Macbook screen connected to my laptop?
I Have a MacBook Pro mid 2009 13 inch and since yesterday the computer will not start, it simply shows a white screen, then the apple sign and then after several seconds this comes up and then it repeats again and again forever with a message that says " your computer restarted because of a problem wait or press any key to continue" but then after about five or six times it comes up wit. A screen that looks like the startup screen but in the middle of the grey/white page there is a circle with a cross through it where the apple sign should be.Â
I have a 2-yr old MBP 3,1 (the first Santa Rosa line) which has recently hit a slew of problems (bad fan, new display, new hdd, new logic board) over the last 3 months. I thought all was fixed then yesterday it suddenly dies, starts kernel panicking on boot, and I can't even boot from an installer disk. I took it in to the Genius Bar today and the guy puts a stick of their RAM in and it seems to work +/- ok. He won't do any more until I put the original RAM back in (upgraded to 4 gigs a year ago). I take the laptop home, and it magically starts working. I grab a couple backups and it starts kernel panicking again so I grab my original RAM and put it in. Now it's still kernel panicking and I'm effectively completely locked out of my MacBook Pro (the RAM worked fine in my wife's 3-year-old MacBook which takes memory of the same specs).
I have a 2010 MacBook Pro running the latest iteration of Lion. Recently, the computer has experienced frequent kernel panics (three today alone) requiring the laptop to be restarted. I have noticed that these tend to occur more frequently when I wake the computer after letting the battery drain down to near or below ten percent of its capacity and subsequently plugging it in after it goes to sleep.Â
The only other clue I have is that every time the computer experiences a kernel panic and restarts, Spotlight re-indexes my hard drive (i.e., the magnifying glass icon in the upper-right-hand corner of my screen has the little blinking red dot inside of it).Â
I have read a couple of things on the internet about how this may be due to Symantec Anti-Virus, which I have installed on my computer. However, that is pure speculation on my part based on a random post on a non-Apple-sponsored discussion board somewhere.Â
Info: MacBook Pro (13-inch Mid 2010), Mac OS X (10.7.3)
The first couple kernel panics I had appeared to have been caused by Trend Safe Web Surfing for MAC i have since uninstalled that and it keeps panicing.. programs i always have open
- safari
- firefox
- skype (text chat only .. never video)
- Outlook for Mac
- Adobe CS5 Dreamweaver  Â
there is never anything consistent about when it happens
