2011 MBP kext removal question

Hi all,
When I suffered from a failed discrete GPU issue with my 2007 ATi machine, kext removal seemed to be the answer floating around on the internet to force the MBP to use the integrated graphics. This worked, with the caveat that the screen brightness was always 100%.
I have now suffered the same issue with my 2011 MBP - how can I force integrated graphics usage without losing brightness control - is this possible?

Download gfxCardStatus 2.3 and use it to disable the GPU. This is a temporary workaround until you get your motherboard replaced.

BootCamp on Late 2011 MBP Question.

I don't know where to start but here goes. I've had boot camp w/ Win7 32bit on my MBP for sometime now with the original HD. I upgraded to a SSD, and removed the optical drive and put the original HDD there. recently decided to upgrade the original HDD to 1TB and CarbonCopy Cloner does not support cloning Boot Camp partitions. So heres what I did to get BC back on my MBP. I cloned my SSD to the new HDD. Removed the SSD and reinstalled the optical drive so I can use BC to partition and install Win7 on the new 1TB HD. The reason why I did that was because my MBP does not support booting from external USB CD-ROM. Now after I got Win7 up and running I removed the optical drive, moved the 1TB HDD back over and reinstalled my SSD as the main boot disk.
Now here comes my real question. Can I wipe the OS X Partition on the 1TB disk or will it cause problems with BootCamp ?
Thanks in advance

Question regarding SSD/HDD setup in late 2011 MBP

Sorry to start a new thread about this topic but I couldn't find the information I needed.
I'm about to install a 256gb SSD in place of the standard 500gb HDD in my late 2011 MBP, replacing the optical drive with the existing HDD. I don't really want to do a clean install, so I'm planning on using carbon copy cloner.
My question is how do I clone only the necessary files (my 400gb of data won't all fit on the SSD)?
I'm planning on putting all apps, system files, both libraries and the shared folder on the SSD, with music, docs, movies, photos and downloads remaining on the HDD.
Is it as simple as:
-select all necessary folders in CCC and clone to SSD
-boot from SSD
-delete cloned files from HDD
-redirect itunes etc to new paths
Thanks in advance.

I have a MacBook Pro 2.4ghz (MacBookPro8,2) (Late 2011) .. would you be able to tell me based on these screenshots if I would be okay putting a 6G SSD in my optical drive bay? Thank you!!

I'm selling my early 2011 MBP because I just bought a iMac. Could someone please tell me how to remove all my information from it but leave the OS working. Thanks so much.

How do I securely delete data from the machine?
Erase, formatting, OS X installs on Mac's

Ram upgrade question on Early 2011 MBP 13

I upgraded my ram from 8GB to 16 GB today. I want to find out if my computer is compatible with this ram. I got a Crucial 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800). So far so good my mac has not froze at all.

Not true. It has been determined that 1600 GHz Ram will add a modest performance increase on 2011 MBPs.
Ciao.

Considering going from late 2011 MBP to MBA. Seeking advice on performance.

I currently have a late 2011 MBP with 4GB RAM, 2.4 GHz Intel Core i5 and am running into some performance issues. My main issue is that it takes time to switch between apps and sometimes to open a new tab in chrome. I have a lot of apps open for work purposes and I'm thinking the slowness could be due to not having enough RAM. When I look at Activity Monitor>System Memory, I see that I have about 1GB in Inactive, 1 GB in Active, and 2 GB in Wired. Then I'm seeing 5.62GB of swap used (that doesn't seem good).
I like how compact the MBAs are and am thinking of getting either the i5 or i7 with 8GB of RAM. I'm thinking that the increase in RAM as well as the flash storage would help with the type of slowness I'm seeing, but would hate to buy it only to have the same problems.
I would love to get some advice on this.

I HAD the same 2011 MBP you have, and HAVE the current Macbook AIR,....theres almost no comparison between the two. You should possibly go use one for a bit at the Apple store etc, however regarding your question "will it be a difference/ big upgrade" the answer is of course yes,....definately so.

AMD Radeon HD 6750M, Early 2011 MBP, 10.9.4 Problems

Hello,
Ever since 10.9.3 update I have a serious problem with my Early 2011 MBP with AMD Radeon HD 6750M card.
First my configuration:
MBP 2.2 GHz Intel Core i7 (Macbook Pro 8,2)
16 GB RAM
512 GB Sandisk SSD and 750 Stock HDD
AMD Radeon HD 6750M and Intel HD Graphics 3000
OS X 10.9.4
I'm usually using my MBP with external display with a resolution of 1920x1080. The display is connected via DVI to Mini Display Port adapter. When I connect the external display, my MBP switches to the AMD card. Here's where the problems begin. If I'm using Davinci Resolve, Capture One Pro or any other software (that I use regularly) that uses the GPU extensively, the cpu usage will rise, the computer will start to feel sluggish and my productivity almost becomes none because even the simplest tasks such as opening another tab in firefox or safari takes anywhere between 1-3 sec. When the computer starts doing that, I cannot play a simple HD video at native fps and the whole machine basically becomes too expensive paper weight. The strange thing is that even after I quit all programs, the system cpu usage continues to be high, around 50% with kernel_task being the star using all this cpu and it keeps using all of this cpu forever, at least until i shut it down or disconnect the external display and manage to make it switch to the internal Intel gpu.
The problem started after istalling the 10.9.3 update and it's still there with the 10.9.4 update. I even formatted the computer and reinstalled everything but the problem still persists.
I haven't experienced anything like this on 10.9.2 and the machine was actually quite fast before that. Now, I have too expensive paper weight on my desk.
Since the problem is very specific, I doubt many users will complain and I doubt Apple will ever do anything to fix it, at least until hopefully the new drivers in 10.10 fix the issue hopefully.
My question is:
1. Has anyone else experienced this and managed to solve the problem?
2. How can I downgrade to 10.9.2? I don't have time machine backup but i have bootable usb with 10.9.2. Will it help?
All best,
Goran

New MBP retina migration question

If I buy the new MBP I prefer to use the new thunderbolt - firewire dongle for migration assistant in target disk mode since they have eliminated the firewire port. However, this dongle is not yet available and a search shows MB air owners have been waiting for over a year for Sonnet's Allegro dongle to come to market. Sonnet puit out it's first Marketing release on this product April 11 ,2011, over a year ago! I think it is optomistic to expect it to appear anytime soon.
So option 2 is to get the thunderbolt - ethernet dongle and use migration assitant from my Time Capsule to my new MBP. The question is how much longer would it take to move 120 GB of data using ethernet versus firewire and are there any difficulties using this method? I have had really good luck using target disk mode in past times and am hesitant about going from the time capsule.

AMD Radeon HD 6750M in 2011 MBP-Graphics Issues-Second Life

Since there were no responses to my question, I have re-worded it. Second Life runs fine on my late 2009 iMac i7 with it's ATI Radeon HD 4850 graphics card. SL freezes at boot up on my new 2011 MBP with it's more powerful graphics card. Message is that "Your system contains a graphics card that is unknown at this time. This is often the case with hardware we haven't had a chance to test. Second Life will most likely run properly but you may need to adjust your graphics settings to something more appropriate..." Nope...I have to Option Command, Esc to force quit. Feedback on this minor issue appreciated.

2011 MBP with 8GB of RAM, generally slow under Lion, possibly thrashing

I have a 17" 2011 MBP with 8GB of RAM and the fastest CPU available at the time. It came with Snow Leopard, and it was really fast with basically everything I threw at it.
Since the upgrade to Lion, it has a general tendency to get really unresponsive. My workload hasn't fundamentally changed. Rather than just hope it's bugs in Lion that will get fixed, I'd like to see if anyone can advise me on things I might investigate, either to fix things myself, or to be more intelligent about identifying bugs I can report.
One thing I notice is that Time Machine backups will bring the system to its knees. Everything will be going along just fine, and then TM will kick on, and all my apps will stop responding. Once TM has finished, things will slowly come back to normal. There's a lot of disk activity, which I have assumed was swapping. Another thing that causes trouble is that mds (and a whole bunch of mdsworkers) will frequently kick on, and will slow down the system.
CPU load is always quite low, but free memory is always very low. (However, in some OS's Free Memory is misleading, because a lot of disk blocks are cached in RAM, so it's not really "used" either..)
What I can't really distinguish for sure is if the system is slow because of swapping/thrashing (which is what I assume) or if it's slowed down for some other reason related to disk activity.
Here are the apps I typically run:
- NetBeans (which is a pig, taking up over 1GB or real memory)
- Safari (which is also a pig, often taking up more than 1GB between the main Safari process and the Web Content process)
- Sometimes Parallels (2GB for the VM, and probably another 1GB for other stuff, because it's also a pig)
- kernel_task typically reports taking up over 1GB of real memory
- WindowServer also reports using 280MB
- various other small apps like Mail, NetNewsWire, Preview, Terminal, Adium, Smultron, Colloquy, none of which use much memory
I got the 8GB, because I knew I was going to use a lot of memory for stuff, and it was great under Snow Leopard. But with Lion, it just doesn't seem to be enough. Even with all of those huge processes, I can't believe that their working sets are really as big as their virtual and physical memory footprints seem to be. I mean it's not unusual for a process to have 2GB of virtual space but only a few 100MB of real memory, and some of that is shared object libraries, where the same physical memory is mapped into multiple processes. (Have shared object libraries stopped being physically shared under Lion?)
Are other people having similar trouble? Any suggested remedies? Any suggestions on how to investigate so I can see if there are any actual bugs?
I would like to understand why my system went from zippy to slow after I upgraded to Lion. Actually, quite a few things have broken. Time Machine has become a pig, bluetooth doesn't work reliably anymore, airport doesn't connect reliably anymore, and lots of little annoying bugs. But this is common for early point releases of new OS's, so I can't complain too much. But for Lion to have really regressed in memory management is definitely not good.

Safari, for what ever reason, has become a huge memory
pig. The longer you are using it the more memory it
gobbles up.
In Activity Monitor, check the Page outs and Swapped used.
This will tell you how much memory swapping is going on.
As for Time Machine, you may want to set your Parallels
HD image not to get backed up by Time Machine. May
help since it is a huge collection of files. But there have been
issues reported with Time Machine and Lion. I don't
use it myself and opt for the cloning methodology and
seperate data backup strategy. Also, in Spotlight
preferences under the Privacy Tab, I have added
my Windows VM folders, for same reason. Unless you really
need to find something on the windows VM volumes when you
don't have the Windows VM active, it just eats up alot
of disk access time.
For solving airport issues check this article:
http://reviews.cnet.com/8301-13727_7-20117247-263/fixing-airport-problems-in-os- x/?tag=mncol;txt
For Bluetooth devices, try removing them, and have them rediscovered if you
can.
Hopefully, this gives you a start on cleaning things up.

MBP 2012 (not retina) replace HD with 2011 MBP SSD?

I have an early 2011 MBP 13in with an Intel SSD running Lion. Wonderful computer. SSD runs like a champ. However, I just bought the 2012 15in (NOT RETINA) MBP, and I want to replace the HD in the 2012 MBP with the SSD from my 2011 MBP. Can I remove the HD from the 2012 MBP, put the SSD from the 2011 MBP into the new 2012 MBP and it will simply work? If it's not quite that simple, what steps must I take to get the SSD from the 2011 MBP working in the 2012 (NOT RETINA) MBP?
(Oh, and for those that are curious...I am not interested in the retina MBP because the RAM and SSD are soldered into the board. No thanks.)

and as most unbelievable things its not true, you can still replace the SSD on both the retina and non retina macbooks. Ram in the only thing you cant replace because of it being soldered (on the retina only).
The ssd in the retina is proprietary so we have to wait for someone to release a compatable module, but it does infact unscrew and come out.
The non-retina macbooks should be as upgradable (hdd and ram wise) as much as the 2011 edition.

2011 MBP throwing Kernel Panics

Hello all,
User is complaining of spontaneous system freezings. I just upgraded the RAM in a 2011 MBP model. Now running 16GB Crucial memory. Ran AST MRI and system passed. Trying to run the cooling system test and the computer is continually throwing a kernel panic at me?
If you could help that would be great -- thank you!

RAM and hard drive/SSD are 2 totally separate peices of hardware. HDD/SSD store data that is read by the system to load the OS and programs and put that data into Memory so it can be displayed on the screen and interacted with.
If the HDD/SSD is not supplying the correct, read that as corrupted, data to the memory that can cause panics. If the HDD/SSD is supplying non corrupted data to memory and you are getting KP then the RAM is faulty and corrupting it.
KPs can be caused by many different things. Faulty HDD/SSD, bad RAM, bad files on the HDD/SSD or some other faulty peice of hardware in the system.
Since you stated you just changed the RAM and you never said it had KPs before the RAM change that is the first place I would start trouble shooting. You never mentioned changing the drive to a SSD so if the SSD worked fine with the old RAM the SSD is fine.

Which kind of SSD hard discs do support with earlier 2011 MBP ?

Which kind of SSD hard discs do support with earlier 2011 MBP ?
I'm using 15 inch earlier 2011 MBP. I would like to replace hard disc to a new SSD hard disc to improve performance. But I don't know which kind of SSD works fine for it. Does anyone work fine? Could you give me some successful experience? Thanks a lot.
BTW, Can I use SATA3 SSD? And any problems here?
Thanks a lot!

is it a hard questions?

External display locked to 640x480 after Windows 8.1 upgrade on 2011 MBP 17 in

I just upgraded to 8.1 from Windows 8 in Bootcamp on my 2011 MBP 17in. Windows 8 ran fine and I was able to connect my Mac to an external display just fine.
After the upgrade to 8.1 when I connect my external display it will only support a resolution of 640x480 and only shows a resolution 640x480 as the is the maximum res it can go. I have also loaded the Windows display driver to the Dell E228WFP to no avail. Any external display I try only shows a resolution of 640x480.
I have removed the AMD Radeon HD7400M from device manager and re-installed the drivers from boot camp 5 but this doesn't resolve the issue.
Any others havng this issue?
Thanks.

Hi,
I ran into the same problem but I found out a solution for my early 2011 15-inch MBP.
Basically, with the 8.1 upgrade, the OS mistook my graphics card for another. More specifically, it saw my Radeon HD6490M as one from the 7400M series.
What I did to solve my problem was go to the Device manager, find my graphics card, right-click to get to the 'Properties' panel, and revert to the previous driver (the option should be available). Thanks to this, it reverted to the driver that was used when I was running Windows 8, and my external monitor is working great now.
I hope this will help you!

2011 MBP only boots in safe mode after yosemite update

After attempting to update to yosemite, 2011 MBP (16GB Ram, 1TB HD) will only boot into safe mode. If I reboot without holding the shift key, I get the Apple logo and progress bar ......... that never goes away, just hangs about half way through. Any help?
Dan

Hey there Danielrbjo,
It sounds like you are unable to boot your mac without using Safe Boot. I would use the other troubleshooting from the following article, named:
Mac OS X: Gray screen appears during startup
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Reset the NVRAM / PRAM
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Reset the NVRAM / PRAM.
If the gray screen issue persists, go to the next section.
Remove third-party RAM and internal hardware
Remove any non-Apple RAM or other third-party hardware upgrades (such as expansion cards or third-party optical drives or hard drives, if present) to help isolate the issue. This is necessary to get as close as possible to the original factory hardware configuration of your Mac.
If you are not sure which RAM modules or other hardware is Apple or third-party, or if you are not comfortable performing these steps, or if you have a Mac mini, consider contacting an Apple Authorized Service Provider for assistance. Otherwise, perform these steps before going to the next section.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Open your Mac to access the memory slots. Refer to the User Guide that came with your Mac, or search Apple Support Manuals for a PDF copy of your Mac's User Guide.
Remove any third-party RAM that has been installed.
Reinstall the Apple RAM that came with the computer if available. Note that Mac OS X 10.5 requires 512 MB or more of RAM; Mac OS X 10.4 requires 256 MB or more of RAM.
If your Mac starts up with only Apple RAM installed, contact the vendor of your third-party RAM.
If you have installed a third-party drive, ensure it is running the latest firmware. Otherwise, reinstall the Apple drive that came with the computer if available.
Thank you for using Apple Support Communities.
All the best,
Sterling
