Late 2011 macbook pro will not perform AHT

Hi All -
I have a late 2011 Macbook pro (A1278) running 10.6.8.
I've tried running AHT by holding D down while powering up as well as trying D+Option. Neither method is working. I've been sure to hold these buttons down before pressing the power key and continued to hold them down but nothing happens. The computer just boots up as normal. Suggestions?

Late 2011 Macbook pro will not detect HDMI

I recently purchased a MDP to HDMI adpater for my late 2011 macbook pro (I have OS X 10.7.5). I hooked it up to my television and tried to use it as a monitor but my macbook pro refused to detect display. Heck the screen didn't even turn blue when I hooked the adapter up. I wanted to make sure my port was working and hooked up my MDP to VGA and it worked like a charm the screen turned blue and my cintiq was detected immediately. I was wondering if anyone else had this problem as well?
Ther is a possiblity that it is the actual adapter because I bought a floor model in an effort to save some bucks. So I'm going to take it back for an exchange later on today and see if that works. But if that isn't the case does anyone know how to resolve this issue.

Did you click the "Detect Displays" button in System Preferences > Displays?:

My 13" late 2011 MacBook Pro will not turn on..

My MacBook Pro only displays one blinking dot on the battery indicator and the MagSafe charger does not display and lights once plugged in and the computer does to respond when pushing the power button
Please help

Run an Apple Hardware Test:
http://support.apple.com/kb/ht1509
It may pick up some information that might give you a clue as to the unusual behavior.
Note: An error free AHT is not always definitive.
I still would go to an Apple store genius bar and have the MBP examined. It will be done for FREE regardless of warranty status.
Ciao.

How do I uninstall Yosemite please ? Since I upgraded my 2011 MacBook Pro will not boot up

My 2011 MacBook Pro will not boot up following my upgrade to Yosemite. How do I uninstall or downgrade back to the previous version of OS please ?

You can't downgrade or uninstall unless you first erase the drive. Try the following:
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X

Windows 7 install on late 2011 MacBook Pro without bootcamp (performance issues)

Hey guys I'm hoping I can get this issue resolved. I have purchased a late 2011 MacBook Pro (radeon 6750m 1gig). I installed a fresh copy of windows 7 without bootcamp. Having real issues with game performance like world of Warcraft. I have done this with an older unibody Mac and it ran great (for any non believer)... But now this time around I'm getting horrible fps in game. I'm thinking it may be driver related it buy I am having trouble finding the right drivers to see if that's then issue. Any help on this would be greatly appreciated.

That is completely false. There is no real need to leave OS X on the Mac if you don't want to, especially with Win 7 or 8. That may of been true with Windows XP but not anymore.
The problem with leaving OS X installed is then you are really limited with what you can do with the drive. You can only have one Windows partition and if you fool with it at all Windows will no longer boot. you can't even change the OS X partition otherwise Windows would boot
Windows 7 will install all by itself. No need for any Boot loaders or Hack Boot system. Pop the Win 7 DVD in the DVD drive and restart. Windows will be installed all by itself. But you do need the Apple support files.
In the end if you are going to run Windows on a computer by itself then you really should not buy a Mac. The hardware is the same and as to the OPs perceived better built quality I personally do not see it. And if you actually read some of the posts on this and other Mac forums you will see that perceived build quality is just a bunch of hype, in my opinion.
To the OP. You aren't missing anything.
If you had carefully read what I wrote, I merely said that doing the install on a blank drive wasn't a good idea. That's because it can create issues the OP is having. A Mac's hardware is no different than a comparable Windows machine, but the EFI/BIOS/Firmware is. Macs are in something of a no-man's land in this regard, as they have neither an old-school BIOS or modern UEFI of recent Windows-based notebooks. I'm willing to bet that the performance problems the OP is having relates to the fact that a straight EFI install on a modern MBP "enables" (for lack of a better word) automatic graphic switching. The capability manifests, but the functionality is not there. Enterprising individuals have been trying to get graphic switching in Windows to work as it does on the OS X side ever since MacBooks debuted with this abliity but with zero success.
Using Boot Camp bypasses this, as the discreet GPU is enabled full-time in Windows. Thus, you will realize proper performance.
As far as perceived build quality, Apple machines are at the high end of the consumer notebook spectrum. They're certainly better than most of the other machines you can pick up at your local Best Buy, but they fall short of business-class machines such as the Dell Latitude/Precision, HP ProBook/EliteBook, and Lenovo ThinkPad.

I spilled on my 2011 macbook pro, will not charge

I spilled hot chocolate on my 2011 macbook pro, and it only got along the bottom front left edge of the computer, and not into any ports or on my charger. Charger was plugged in at the time. Computer shut off a couple of minutes after, so I restarted it,and the fan was running very loudly. \the trackpad was a little bit messed up, so I did an SMP reset and the computer is now fine. However, my charger will not work. When plugged into the laptop, it doesn't charge and the light doesn't come on, though it has no visible damage. Is the problem with the laptop or charger? Could the computer have damaged he charger at the time of the spill? Could the hot chocolate have seeped into the seam on the bottom of my computer? It was only wet for about 15 seconds.

Normally, if electronic device suffers from the accident of liquid spill, you should shut down them and plug off power supply immediately to avoid possible electricity broken. In fact, it is not easy to detect visible damage by visual look. In regard to your example, i mean hot chocolate actually penetratres electronic component inside your computer and cause the fault for hardware system. What you need to do is remove the computer case and try to dry internal electrical circuit out. If this method doesn't work, you should bring to repair service. Good luck !

Late 2011 Macbook Pro Wont Boot into AHT

My brand new MacBook Pro use to boot into the Apple Hardware Test.
Recently I was having software problems so I restored my mac from the lion restore partition, now I can’t boot into the Apple Hardware Test. I don’t have restore disks or software disks because my MacBook Pro did not come with them Any Ideas?
Thanks Kyler

First off, some other forum members have reported having to hold down Command-D instead of just D to get the AHT to load.
If that don't fix it, as per this article ( http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh35727.html ) it can be loaded from a USB disk. Since your Mac came with a factory-installed Recovery partition, you can concoct a bootable USB startup disk (hopefully containing the AHT) as per these instructions: http://support.apple.com/kb/DL1433
Hope this gets you the AHT back.

Late 2011 Macbook Pro - worse graphics performance than early 2011?

As per Apple.com:
Apple's Late 2011 MBP 15" claim 2X graphics performance as per Apple's tests from the last Nvidia based MBPs.
Apple's Early 2011 MBP 15" claimed 3X graphics performance as per Apple's (seemingly identical) tests from the last Nvidia based MBPs.
http://imgur.com/lAvek
Can anyone at Apple or otherwise comment on this?
Specifically, It seems the Half Life 2 test drop sfrom X3 to X2 on the Late 2011 model, even though it has the 6770 AMD card in it.
-Did Lion kill performance?
-Did Apple downclock the chips after reveiwers (anandtech??) found that while using discreet graphics battery performance dropped to roughly 2.5 hours?

It's likely the Half Life test is not compatible with Lion, nor is older 3D games.
If you want to use a test, use a more neutral test like Cinebench, GeekBench etc.
Or simply visit Barefeats and they will tell you

Remember programs are always in a state of having to be updated for the newer hardware and operating systems.

Late 2008 Macbook Pro will not start if left unplugged overnight

Hello,
I've been having the following problem on a Late 2008 MBP, only owner and this just started a couple weeks ago (along the cold weather perhaps?):
Every morning it's very hard to start the MBP, I press the power button and get nothing, not even LED light. I already did SMC & PRAM reset with no apparent improvement on the issue. This happens even when the battery is fully charged, which was replaced for a new one two years ago.
I manage to start the machine after several combinations of removing the battery, plugging the AC adapter in it, butting the battery back in, etc. yet I haven't found a way that actually works.
If the machine is left plugged to the AC adapter overnight, it will boot without any hassle the next day! Somehow is leaving it on battery only that bricks the thing.
Is this a problem with the motherboard? Once it starts I can turn it on, off, send it to sleep and be on battery like the machine is brand new! HELP!
OS: 10.9.5
AC Adapter: 85W replaced around 2010
Battery: Health 96%, Cycles 143 (funny, yesterday was 97% and not long ago 99% or even 100%)
Additional peripherals: Expresscard USB3 (has been removed for testing)
Mods: 8GB RAM & Samsung 256GB SSD

Thanks for taking time to respond to my post, I understand it's old hardware but hey, if there are Macintoshes still running in the wild, why can't I have this MBP run for another decade!
I did what you suggested; cloned the SSD to the original HDD and replaced the RAM with the old Samsung memory – got the exact same result.
In fact it was harder for me to start the machine this morning. I couldn't do it with the old HDD and RAM so replaced them with the new ones AND still struggled to boot. I even reviewed all connectors where properly in place within the motherboard, no dust or anything strange inside the machine. I removed and re-inserted the RAM, did SMC reset and that seemed to do the trick (this time the machine booted only with the battery inside).
I read somewhere there's a thermal sensor involved in the booting process, could this be temperature related? Maybe moving things around just happens to warm up the parts. Are there any other type of tests I can perform on the RAM/Power Management to rule out any other problems? Is there an internal battery that might need to be replaced? I haven't suffered from clock reset or anything like that. I've had other computers not boot at all, both Mac & PC, and it's usually GPU related, this machine doesn't behave like that at all but could that be the problem?
Like I said, if I keep the machine in sleep mode or plug it in to charge before turning it off, there's no problem booting the morning after. Once the machine starts, I can turn it off and on even if the battery is removed and have never experienced a malfunction while on. It seems the lack of power is what bricks the machine regardless of the SSD/RAM or peripherals connected to it. Battery is charging to 100% again.
Any other suggestions are welcome! Will try not to leave the machine off or disconnected in the meantime.
Thanks again!

2011 Macbook Pro will not detect Sony Barvia

I have a 15 inch 2011 Mac Book Pro 10.7.4 and am trying to hook it up to a 55 inch Sony Bravia KDL55HX729. I am using a rocketfish mini displayport to HDMI adapter. The problem I am having is that the computer can not detect the TV. There is no arrangements tab when I went into displays through system preferences. If anybody has any tips it would be appreciated.

Did you click the "Detect Displays" button in System Preferences > Displays?:

Putting a SSD in the optical drive bay of a late 2011 MacBook Pro.

I want to put a large Solid State Drive in the optical drive bay of my late 2011 (Model ID 8,2, 2.4 GHZ quad i7, 8 Gigs RAM, SSD boot drive) using the carrier and drive from Other World Computing. The "About This Mac" box shows that the optical drive is 6G so I'm thinking that it should be OK putting a 6G drive in that bay, but OWC says that MacBook Pros have only a 3G optical drive capability. I know this was true on earlier models, but my bay says 6G.   The 6 G SSD's are faster and have a longer warranty. I do pro audio work and want to record to the new drive with speed and reliability. Is there any way to prove that my MBPro will handle 6G? I was told by someone at OWC who looked up my my serial number that it would work, but another tech guy at OWC said they didn't recommend it. I'm thinking that they just issue a blanket "no" answer to cover themselves against people ordering a 6G drive for a machine that wouldn't handle it. Before I order a 6G drive is there a way I can know for sure if it will work?
Many thanks,
Robert

If the computer is correctly identified as 15-inch Late 2011 MacBook Pro, and not an Early 2011 build series,
according to MacTracker database (http://mactracker.ca download application) optical drive interface supports
the same spec as the hard disk drive...
Hard Drive Interface    6.0 Gbps Serial ATA (SATA)
Optical Drive Interface    6.0 Gbps Serial ATA (SATA)
So should there be an error in identification, that would make a difference. Some Early 2011 models may
have the 3.0 Gbps or 6.0Gbps data rate in the optical drive. All Late 2011 models should be 6.0 Gbps.
Good luck & happy computing!

What external drives work well with a late 2011 MacBook Pro? I ask because I just found out the hard way that a Samsung EVO 840 does not. Also should I avail myself of something that works with Thunderbolt or Firewire?

What external drives work well with a late 2011 MacBook Pro (I7, Lion OS) apart from my Kingston flash and USB drive, and the SD drives that I use in my cameras and recording devices? I ask because I just found out the hard way that a Samsung EVO 840 does not. Also, should I avail myself of something that works with the Thunderbolt or Firewire connections? I'm looking to back up music and video files created and/or processed in Logic Pro and the Adobe Production Premium software suite (Premier Pro, After Effects, Audition, etc).

Hmm, not sure what problems you had installing this drive. The review here gives it good marks for Mac:
http://www.amazon.com/Samsung-Electronics-EVO-Series-2-5-Inch-MZ-7TE1T0BW/produc t-reviews/B00E3W16OU
There does seem to be a lot of prep to make it work:
"1. Preparation to install your new shiny SSD
1.a You will need a migration tool (I used the Sabrent kit USB 3.0 to Sata that was suggested in these review) see link http://www.amazon.com/gp/product/B00DQJME7Y/ref=oh_details_o03_s01_i01?ie=UTF8&p sc=1
1.b You will need to download a trim enabler (mid 2012 macbooks only support native trim with apple brand ssd's) I recommend going to cindori.org and downloading trim enabler version 3.xx. You can do this step before or after the OS migration
1.c You cannot use the Samsung SSD migration software *don't worry Mac has its own imaging/migration utility*"
Also in those reviews:
" Only down side when using this product in a Mac Mini is you will be required to download and install Trim Enabler so that your drive performs optimally on your Mac device. This is an Apple issue, not Samsung, but it is an extra step you will have to take after you install the hard drive, and any time you perform an OS upgrade." He rant's on.
Personally I only deal with OWC:
http://eshop.macsales.com/shop/SSD/OWC/
They are very knowledgable and if there's a problem they will gladly take back the item. (Never happened to me yet - 8 years and counting).
Just upgraded my 13" MBP 2011 to 120 GB for $79. Adobe CS 6 opens in 3 seconds! Awesome!
When I was in Chicago I had a pro photographer for a client. She wound up with 4 internal drives in her Pro, 4 external drives and an dual array locked in a steel vault in the basement. All from OWC. OK she was a bit paranoid. Great client though.
As far as value for price:
http://eshop.macsales.com/item/OWC/MES3FH7500G/
500 GB for $130.
However as far as reliability is concerned:
http://www.rockpapershotgun.com/2014/01/30/are-ssds-reliable/
http://www.extremetech.com/computing/173887-ssd-stress-testing-finds-intel-might -be-the-only-reliable-drive-manufacturer
So sudden power loss is an issue with SSDs.
Personally I'd go with a moderate sized SSD internally and a conventional external for backup. An array would be the most reliable.

Hi, I have a late 2011 MacBook Pro but cant get the mirroring function to work with Apple TV. I've got the most recent Software 10.7.5 but cant see the mirroring icon or turn this on. I'm able to mirror from my Ipad but not my Mac, any thoughts?

Welcome to the Apple Support Communities
AirPlay Mirroring is supported on your Mac, but it needs OS X Mountain Lion (10.8). See > http://support.apple.com/kb/HT5404
You have two possibilities:
1. Make a backup, open App Store and purchase Mountain Lion to upgrade to this OS X. Then, you will find the AirPlay Mirroring icon at the top right of the display, on the menu bar, or on System Preferences > Displays.
2. Keep OS X Lion and use AirParrot > http://www.airparrot.com
Both options work properly, but I recommend AirPlay Mirroring as it doesn't need a third-party program

Late 2011 MacBook Pro (Mountain Lion 10.8.2) backlight keyboard not functioning properly?

I have a late 2011 MacBook Pro running OS X Mountain Lion 10.8.2 and for some reason, the automatic backlight keyboard will not funtion as it should. When I have the "Adjust keyboard brightness in low light" option enabled in settings, and I turn on the lights, my backlight keyboard stays at full brightness. Then, when I turn off the keyboard, then the lights, the keyboard does not turn on! Correct me if I'm wrong, but I am pretty sure that this was a feature in the MBP lines.

Try a SMC reset. Shut down the computer. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. Release all the keys and the power button at the same time. Press the power button to turn on the computer. Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
