so i got my 3 week old mbp 15 (which i dropped and dented) replaced today due to kernel panic/ram failure/apple store only had 1 memory stick in stock...
my question is, what causes ram failure? i dont want it to happen again, i didnt install any 3rd party ram.
This occurs on my MBAir and my MBP 2.5 I would click on the video camera on the AIM Buddy List>Preferences>Messages>My Balloon Color>then a crash report Kernel Protection Failure>iChat shuts down...
Been on the phone off/on with AppleCare Techs, but no definitive answer or a fix that would resolve the issue...
Long story short, I accidentally deleted my iChat and reinstalled it from my leopard boot disk but now iChat wont work. Whenever I click on someones name in my buddy list or if i go into my preferences and click on the messages tab, iChat just freezes and crashes. I've tried deleting the com.apple.iChat.plist, reinstalling, repairing disk permissions, etc... I really don't know what else to do. Any ideas?
View 7 Replies View RelatedYesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

Macbook Pro won't boot. Symptoms preceding failure included failure to open Firefox. When trying to cold boot I can get as far as the start-up sound, the Apple logo, and the spinning whieel (spins for a bit but not for very long) and then major failure. Not running Liom.

Sleep seems to have stopped working all of a sudden on my recently upgraded iMac. The only thing I remember doing was repairing disk permissions and changing a few iChat preferences.
The console shows the following;
kernel Sleep failure code 0x00000000 0x11000000
A reboot does not clear the condition
Yes you read that right. Your brand spanking new MBP will use a 32-bit kernel as default.
You can force 64-bit kernel but some of your hardware will not be working.
So all that marketing crap about the benefits of 64-bit etc are all B.S.
I don't want a million threads about how this will not effect the running of 64 bit apps, etc. because it will. Your 64-bit app will run but it will not be able to address more than 4Gb of RAM.
There are also many more advantages to having a 64-bit kernel.
I've recently attempted to install 2 sticks of 2GB RAM into my MacBook Pro, but unfortunately had jammed one stick in the lower RAM compartment (Apparently I forgot to enter it at 45�) and had a rough time getting it out.
The RAM stick is busted and had to replace it, but I'm quite sure the slot might suffered a bit.
What are the signs of RAM failure?
After trying several times to upgrade to Snow Leopard and finding out, per a post here to the community, that my MacBook had a CD reader instead instead of a CD/DVD reader (you can see the whole drama here [url]..
'AmazonBasics USB 2.0 8x DVD Writer External Optical Drive (Black)' by AmazonBasics USB 2.0 External Slim DVD Writer
and tried to upgrade to Snow Leopard from that.Everything was going great - until the two minute mark. And then the external DVD reader kept spitting out the DVD. I kept putting it back in and trying it again.
After about 10 minutes of this, I restarted the computer. It started and got the flashing question mark sign. I started the DVD reader again, and after probably 20 minutes, it started installing SNow Leopard again. And probably at the two minute mark, I got the error message "An error occurred while installing Mac OS X."Everything is siting silently now. There's an error message and a spinning wheel on my screen. The reader is silent.
I'm convinced this is a power issue - the DVD reader/player is drawing power from the Mac, but obviously, it's not enough. A search of the house has found no power adapter that works with this DVD player. I'll be going to Radio Shack tomorrow and hoping against hope they have something. And I have an appointment at the genius bar at the Apple STar on Saturday.

My 2.33GHz C2D MacBook Pro running 10.6.3 has suddenly decided it doesn't have an optical drive installed!
If I put a CD or DVD in the drive it will pull it in, spin but fail to recognise the disc. It is impossible to eject the inserted disc by any means - except by using a piece of cardboard to stop it spinning after a restart. I have tried data, audio and video CDs/DVDs.
System Profiler says I only have a hard drive attached to Serial-ATA and have no Disc Burning devices installed.
Has the optical drive failed? If so why does it still spin up if the computer doesn't know the drive is there? Does the fault lie elsewhere?
while enjoying a beautiful, sunny day here I was outside with my MBA surfing the web. I had a few other apps open at the same time like iTunes, QuickTime and Mail. Safari all of a sudden beach balls and I wait a bit until I try doing a force quit on it. After a while I still have no response and I cannot close it. So, I hold my breath while forcing a shutdown with the power button. To make a long story short, I ended up with the flashing question mark on the gray screen. Now I'm doing a remote reinstall from my MBP!
View 24 Replies View RelatedSnow Leopard says service battery, and for the 3rd time the battery has dissolved into failure in exactly the same way. Stays high for a month (99%), drops to 8x%, climbs to 9x% and then finally dies... Now, this would be my fourth (yes 4th!) battery, and the 3rd time the Laptop will have to go into an Apple store, as the power circuitry in here must have something wrong. So... new MBP time I think [Applecare for 3 years, 26 months into my 36 month warranty!]
View 12 Replies View RelatedJust experienced a hard drive failure right now on my MacBook (2007). Everything had froze and I shut it down. When I started it again, the screen was dimmed and the Apple jingle went on a louder sound then before. Is this a sure sign of a MacBook hard drive failure or would it be related to something else, for example, the logic board?
Also, what should I do now? Last full backup was 3 weeks ago and I had worked on lots of things between that period of time and now.
I have a late 2008 MacBook Pro 2.4GHz with 2GB of RAM. I can't say it's ever been magnificently fast, but I always blamed it on the memory. I've always intended on upgrading it, just never got around to it. I've also been away for 6 months, so haven't been using my computer.
But today I've been trying to use Photoshop & it's hideously slow! Even the simplest task such as a desaturate command can take as long as 2 minutes! Admittedly on a large size document.
I have iStat in the menu bar. When performing these tasks I would assume it would display some sort of indication it's processing in the CPU. But it displays Photoshop only using at much as 16% CPU & the memory having 500MB of inactive memory? My brother had been using my computer away & was constantly complaining of the speed of it. He suspects it could be a CPU issue. Am I correct in thinking Photoshop should be using more CPU when processing a task?
I click on a video it simply says plug in failure, if im lucky 5 seconds of advert!? im currently runnin Lion 10.7.3 and have tried uninstalling adobe flash and reinstalling but still no joy!?
View 8 Replies View RelatedMy laptop is MBP 13" early 2011, after using a usb bluetooth adapter( built-in bluetooth had compatiblity problem with my mobile phone) and unplug it, and then found the built-in bluetooth is not working any more, it can search devices, but it won't establish connections or pair with other devices. At firs I thought it was the bluetooth driver or configuration problem, I try to reset factory setting using the develper tool Bluetooth Explorer, then reset kext file, even tried installing a new lion, but the problem remains. So I think it's not driver/configuration problem now, it's hardware failure, but wait.. just caused by using other usb bluetooth adapter? I really can't understand why apple will let such thing happen....

Just got my new Macbook Pro Retina. Migrated my applications and data from my Macbook Air. Everything worked great. Apple Update advised that new updates were available. I accepted and ran the updates. Now it gets a kernal panic at boot. Can boot into Safe Mode however. I used Command R to reinstall OSX but that did not correct my problem. Same kernal panic persists.

My question is how many time does the hard drive have to go bad before i can get a new computer? If apple updates the macbook how do they determine which config i would get as a replacement? How would it affect apple care? i have registered it already.
View 10 Replies View RelatedAs I am in the process of replacing a hard drive on a Macbook Pro, I begin to notice that there are MANY posts and experiences of individuals having to replace a dead hard drive at some time or another in their Macbooks. Is this typical? Should this be something I'm prepared to endure? Would it make more sense to buy my own hard drive in addition to a new MBP?
It's ridiculous that I even have to worry about something like this on a new purchase but I'd like to be prepared.
I wanted to reformat my mbp. In doing this, I used the 'erase and install' method in my leopard restore disk then installed bundled applications dvd that was included with it. I then installed/upgraded to snow leopard then used software update to download the updates. Before this, there seemed nothing wrong with my mbp. After downloading all the available updates (~990mb), it asked for a restart to which i agreed . i watched it while it was installing the updates but for some reason before it was able to end, stated that an error occurred thus it restarted. Now i get stuck with the startup screen (the one with the apple logo in the middle with a rotating circle of lines just below it). It wouldn't stop so i hard reseted it but to no avail, still stuck with the startup screen.
View 6 Replies View Related2008 mac-book pro, started having these warning screens come up by which it states that i have to turn off/ restart ( only option as no other controls work). These became more frequent until yesterday i turned it off as per warning to then restart but now it wont turn on at all.
All that happens now is that when press the power button the fans come on for about 5-10 seconds and then it just all abruptly turns off, the screen stays blank and there is also no start up sound either.
In both Snow Leopard and Lion, I am experiencing start-up disk failures that cannot be repaired by disk utility. Does anyone know what can cause this?

I take a chainsaw to my Mid 2009 Mac Book Pro.It had been pretty faultless until recently when it started being slow to boot and generally just hanging for a short periods, and then carrying on as normal.Then I had major errors on the 500gb hard disk, which prevented the machine from booting. Using disk utilty, I decided that I needed to wipe and start again. Fortunately much of the data was backed up. I re-installed and all was well for a short while. However, about 3 weeks later I had the same issue, and so I decided to replace the hard disk, even though it did not seem to have any errors or SMART warnings.I put in a new 750Gb disk, and all was well for a few months. Last week I was working abroad in Norway. I rebooted into boot camp to run some software and then back again into OSX and then disaster struck again. (Strangely my boot camp partition has had no issues at all on either hard disk). I couldn't boot into OSX and the emergency recovery (I'm on Lion) came up. Disk Utilitiy told me that the it couldn;t repair the drive.
Now after two hard drives I am a little stuck. The incovenince is massive as I am a working all over the place and rely on the my normally trusty MBP. I am almost ready to replace the MBP, but in truth I can't really afford to do so (in these economic times).Can anyone point me as to why this may be happening. I am hoping it may be bad Ram (easier to replace than a board), but can anyone point as to how to diagnose it. The apple hardware test program I remember for the pre-OSX days doesn;t seem to available now.

My primary MacBook is suddenly now powering up - Tried the power management reset....removing battery/power and attempting restart after 12 hours and so forth. Does this sound like Logic board? Is there a chance the HD data can be retrieved if it would be installed in another MacBook or...if Logic board is repaired?

I've had my iPhone 3g 8gb since June 2008 and loved every minute of it. It's been through it all. Even dropped out of a helicopter last week. Ok it was only a fall of around 6ft but still, it sounds epic. I've recently gotten a hold of a Macbook 2.1 2ghz 13" white. It's a late 2006 model and the drive has failed. I planned on replacing the drive myself and apple have kindly sent me the recovery dvds free of charge. Tiger 10.4.11. I read on here about the extended replacement scheme for failed drives on here last night and I think I qualify, however I may still put my own drive in it. Out of my stick just to get things moving along. Once that has been done I plan on upgrading to snow leopard 10.6. I'm curious to find out what drives this machine will support and how much ram it will take and benefit from.
