Macbook pro 15" late 2011 Kernel panics

I started receiving this Kernel panic code yesterday. The backstory is that my macbook became slower and slower and I had to hard reset a few times just to tbe able to use it. I removed the hard drive and used disk utility on my minimac and a USB connection to try and fix the flashing file folder I had just booted to. I didnt have original installation media and my disk warrior dvd wasn't available either so I thought this was my best option. After the repair "completed", I began to receive this error every time I started the computer. I can't boot to anything at all now. Help!!

Macbook Pro 15'' Late 2013 Kernel Panics

I am now on my third machine (model 11,3) in two weeks. I did a clean installation of OS X to rule out a bad OS X image. Hardware diagnostics at home and in store passed on all three. No third party drivers or software associated with the panics. The panic can usually be reproduced by toggling Airplay mirroring to my Apple TV when playing an mp4 video via quicktime/iTunes fullscreen.
I submitted a RADAR report- they have accepted the ticket and are waiting for me to perform a kernel core dump to follow-up (I can't get the server side machine to cooperate though!) I have been responding to multiple threads regarding this model and this issue >>> ( Kernel Panics in brand new Retina MBP running Mavericks). Over all three machines, I noticed the following trends:
1) The panic is almost always related to sending/receiving large amts. data over a network - whether streaming via Airplay, or importing a high resolution scan from my wireless printer. In the former case, it is reproducable.
2) The backtrace is almost always related to the IOAcceleratorFamily2 bundle of drivers
3) The corresponding thread is inconsistent
4) The panic type is usually type 13 general protection, but sometimes type 14 page fault (indicating the system is trying to access an invalid memory address). Never any other type.
5) Never any screen artifacts. Always a hard panic and system shutdown.
If anyone else has this issue, please respond and share your experience. If anyone has suggestions, or further insight, it would be greatly appreciated. What could possibly being causing this given the details outlined above? A bug in OSX itself seems to be the only plausible answer...
Help with setting up the server side machine for the kernel core dump would be great (I have read the tech note and followed those instructions)-if this is too broad, I will make a different question out of it because I want the focus to be on the panics themselves.
Thank you in advance!
Here is the latest of my panics:

I contributed myself a couple of log dumps there. I suspect it's software related.

I have a macbook pro 13' (late 2011) 2.8Ghz Intel i7 memory 4GB 1333 MHz DDR3 and have upgraded my OS X Lion to Mavericks. Everything has slowed down. How do I go back to the older OS X Lion? Or should I improve speed differently?

I have a macbook pro 13’ (late 2011) 2.8Ghz Intel i7 memory 4GB 1333 MHz DDR3 and have upgraded my OS X Lion to Mavericks 10.9.5. Everything has slowed down and the battery lasts a bit earlier. How do I go back to the older OS X Lion? Or should I improve speed differently? Would improving memory to 8GB help?

What is the max memory allowed on a macbook pro 15" (late 2011), and what speed is the max speed allowed?

Hello,
I own a Macbook Pro 15" (late 2011) and I would like to upgrade the memory. I want to go with two 8gb sticks but if the motherboard only supports 8gb then I will have to stick with 8gb. Also, the ram that I have in currently, which is the 4gb that came with the mac, is 1333 Mz. Would I be able to upgrade to 1600 Mz on this laptop?

Max is 16 GBs. Do not attempt to use memory with specs that differ from those required by your hardware.
Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM

MacBook Pro 15" Late 2011 Problems with iMac 27" Late 2009 TDM

Hi,
I just got problems with my iMac 27" Late 2009 (Mini-DisplayPort) and my MacBook Pro 15" Late 2011 (Thunderbolt).
When I try to use my iMac as external monitor for my MacBook, there are massive glitches and graphical bugs on my second screen.
I bought a MDP-to-MDP wire from Belkin which works perfect on other computers.
I tried these things:
- Disconnected MagSafe from MacBook + unplugged all USB devices + switched graphics to discrete.
- Shut down all computers ... then booted MBP, iMac and triggered CMD+F2
- SMC, PRAM reset on both devices
The cable works, because:
17" MacBook Pro Late 2011 works perfectly on my iMac screen with my Belkin wire!
I connected my MacBook Pro 15" to a 27" Cinema Display and it works flawless.
After that I plugged it out and tested it again with my iMac screen -> suddenly it works.
Retriggering CMD+F2 or replugging breaks it again with massive bugs.
The MacBook Pro 17" is on 10.7.2, 15" is on 10.7.3, but I also tried to trigger dual screen in 10.7.0 setup with the same issue.
Maybe its a problem with the internal 6750M of my MacBook Pro 15"?
The 6770M of the 17" is working well.
Sample Video:

All updates/firmware updates of iMac and MacBook Pro are installed.
Any solutions?
Greets,
Kai

Macbook Pro 13" (Late 2011) - High Definition Audio Device - Code 10

Hi, i installed Windows 7 Ultimate 64 Bit via Boot Camp on my new Macbook Pro 13" (Late 2011). Driver Disk was installed, but the "High Definition Audio Device" couldn't be started. Status is Code 10. Normal Cirrus Logic Audio is working. Any advice, how this could be fixed? Would be nice, to have audio over the Mini-Displayport HDMI Adapter on Windows as well (Works perfectly with Lion).
Thanks,
Thorsten

I have the new macbook pro from late 2011. when i try plugging my cannon gl2 into the mac via firewire 800 it does not show up in iMovie as an option to import from. i even have gone into my settings on the camera and changed it to vcr.

I have the new MacBook Pro from late 2011. "the one before the new ritina display" i have a cannon gl2 video camera which is mini dv. when i plug it into my mac via firwire 800 it does not show up in the iMovie. i have set the settings on the camera to vcr mode and changed it to av->dv out. when i click on the import from camera on imovie it doesnt even show my camera in it. it just gives me the option to import video from my facetime camera. the camera is turned on the wires are connected i know for fact that its a firewire and not a usb. i know what they each look like. i bought the firewire cable and it was marked down cause it was an opened and used item. would it be possible that it could be deffected and if that is not the reason what other options do i have?

I would say that odds are high that you have a bad cable. Maybe that is why they returned it.
I would suggest trying a different firewire cable.
You can find Firewire cables inexpensively at monoprice.com. You need a 4 pin to 9 pin firewire cable.
Here is a link.

Other things to check:
Is your camera plugged in to wall power (not to batteries only). Must be hooked to an AC power source to import.

Macbook Pro 17 Late 2011 vs Macbook Pro 13 2012

Hey
I have a Macbook Pro 17 Late 2011 model, its works like charm but my onyl problem with it , its too big for me , i travel a lot and its not really good for portability. I use this mac mainly for coding and developing and playing WoW (in BootCamp) but i play nothing else. So my friend said he is willing to buy from me and i decide to get a new macbook pro but the 13" for portability and its also fair enough for coding but im afraid thats its not enough for playing WoW. My friend pay me 1800€ and i found a brand new Macbook Pro for 1050€ + 300€ (for 256gb ssd and 16gb ram) so its gonna be a fast machine but maybe still not enough for WoW. What should i do?

The 17" model is one of the last that supports Express/34.
Thunderbolt does offer more expansion options, but at additional cost.
Make sure the 13" model you get has built-in optical drive unless you don't use it.
Make sure any games you develop for support the graphics card of the machine you end up getting. If they don't, don't expect them to magically work on your machine.
I typically have found the recommended graphics card is the only one that works. Minimum graphics card may at random not work, unless you do no multitasking with many games.

How long to boot MacBook pro 13" late 2011?

It takes 1 minute 30 seconds to startup my macbook pro 13" late 2011 (2.4ghz i5 processor, 4GB RAM)
This seems like a long time? I have Microsoft Office and Photoshop installed, will this slow it down?
Thanks!

if you have a normal hard drive installed - it usually takes a minute to desktop when you power up.
check your login items to see what's loading when you first power up your Macbook.
you can also go to disk utility and verify your disk permissions - repair them if errors are found then restart your Macbook.
see if that helps your booting time.
good luck

Because your MBP does not require it.

Macbook pro 13 late 2011 turns on but no display and light

Hi i have got macbook pro 13" late 2011 which turns on and i can hear the chime but there is no display and ligh in the screen its completely blank. Anyone had this problem and how did u solve this ?

Have you tried booting into the Recovery HD and running Disk Utility and checking to see if the HD needs repairs?
Restart holding Command + r and at the recovery screen select Disk Utility. Then select Macintosh HD and click on 'repair disk'. If anything gets altered click on repair disk again until you get a clean pass. Restart as normal from the Apple menu. More info here about the Recovery HD:

Macbook Pro 13" (Late 2011) Bottom Plate Bulging

Hello there,
I own a Macbook Pro 13" (Late 2011). I have had it for sometime now.
I noticed that the bottom plate (the piece of aluminum that can be removed) is slightly loose in the front. There is a slight retreat when I press down on it. This is not happening to my newer Late 2013 15" Macbook Pro.
I heard that this can be caused by a swelling battery?! My battery has around 350 cycles on it.
Should I be concerned? Is it necessary to take it to an Apple Store and have them take a look at it??
Thanks for your answers in advance.

That could be the case. It wouldn't hurt to have them evaluate it at an Apple Store as the appointment is free.

Macbook Pro 13" Late 2011 hard drive fails, how to replace hard drive?

Hi!
I have a Macbook Pro 13" Late 2011 (OS X Mountain Lion v 1.3.18 (352.4). I tried to install OS X Mavericks but it showed this error message:
"This disk has S.M.A.R.T. errors. This disk has a hardware problem that can't be repaired. Back up as soon much data as possible and replace the disk."
The laptop was still doing fine so I didn't do anything. Then it started to act funny: iPhoto stopped working, hangs when I watch video streaming, and it started to run really slow. I only use the laptop's basic features- internet, watching movies, editing using iMovies so it's really strange for me that the hard drive failed all of a sudden.
I called Apple support and a kind fellow tried to troubleshoot it, thinking it was only a software problem. In the end, he said I need to bring my macbook to the service center and have the hard drive replaced. I know it will cost a lot so I want to replace the it myself.
Here are my questions:
1) Can this problem really be solved by just replacing the hard drive?
2) Can I use SSD this time so my Macbook can run faster?
3) What SSD is recommended for my late 2011 Macbook 13"?
4) I don't have the installation disk, can I still install the OS X Mountain Lion? How?
I am looking for other sites as well but I hope this community could share some tips too.
Thanks a lot!

I've switched out the hard drive on my Late 2011 model several times and I've never disconnected the battery cable.
In my "Opinion" it is not necessary to do that. Not sure if it is or not recommended by Apple.
EDIT:
I just looked at my User Manual, PDF I downloaded from Apple, and there is no mention of disconnecting the battery.
Here's a link to the manual for my model.

MacBook Pro 13" Late 2011, 16GB RAM and Apple Premium Service Center

Hello all,
My dad has a MacBook Pro 13" Late 2011, it came with a 4GB RAM. When he got Parallels and installed Windows 8, 4GB RAM were not enough to even deal with Safari so he had to buy 16GB RAM from Cruical. Today when he went to Apple Premium Service Center here in Qatar (51 East) they refused to install the x2 8GB RAM and only installed one of them. They kept warning my dad that installing the whole 16GB can cause issues with the MacBook Pro HDD and can make it go faulty. I wanted to ask if installing RAMs can pose the HDD life to any danger. Because my dad uses his Mac for work and wouldn't like to lose any of his files against small additional speed.
Thanks.

its very easy to do, here are step by step instructions with photos

MacBook Pro 13'' late 2011 battery health problem!!! HELP!!!

I have a MacBook Pro 13'' late 2011.
It's this normal? How do I increase my battery health?
Can I change my battery?

When did you buy it?
Do you run it down to near zero % before recharging? Which is a bad thing to do.
Do you charge it to 100% before you take it off the charger?
Do you always disconnect the charger once it reaches 100% even if you are right next to an AC outlet. Which is a bad idea.
Batteries only last so long. Over use it and it will go bad sooner.
