Late 2011 MacBook Pro Audio Crackling from 3.5mm Output and USB Audio Devices.

Howdy. I don't know what's wrong with my laptop. Recently any headphone I have used with the 3.5mm output has been crackleing. I assumed the jack it's self was broke but when I set up my Audioenndine D1 amp it is still crackling from videos on YouTube, Netflix, iTunes. etc... It even crackles when there is nothing playing. If anyone has any idea what is going on I would apreaciate it.

You can try a NVRAM/PRAM reset:
Disconnect all peripherals, power off, power back on holding the following keys COMMAND OPTION P R
continue holding till you hear the start chime 2 times then release, reboot.
If it is still crackling it may be a hardware issue, you can bring it in to a Genius bar and they will disgnose it for free, and give you options.

Late 2011 Macbook Pro won't sleep!

So I purchased a late 2011 macbook pro brand new from an apple store 3 weeks ago. Everything seemed well at first (except for a wake issue I had... odd)
Anyways... I started noticing that my notebook wasnt going to sleep, so I adjusted the power settings to sleep after 1 minute...
Sometimes the laptop will sleep after 20 minutes or more... sometimes it won't sleep at all (on all night!)
I'm wondering what the heck is going on? I tried re-installing Lion and using migration assistant to bring all my files back... no dice. same symptom.
-I've re-installed Lion
-I've tried SMC and PRAM resets
-I've tried "pmset -g assertions" and see no conflicts
-I've tried "pmset -g" and see nothing odd
-I've tried clicking / unclicking all the "sharing" settings
-I've made sure ALL applications are closed
-pmset -g log returns a few "slowresponses" but nothing too crazy (200ms)
-system log returns some odd "wake for GIGE (network)" responses while im trying to make it sleep.
-I deleted all printers /ques
The system WILL sleep if i manually click "sleep" or use the power button.
The system WILL sleep if i unplug the power cable and close the lid.
I have a 2nd display using a thunderbolt to DVI adapter... but unplugging this seems to have no effect.
What am I missing? could this be a logic board issue on a brand new mac? I'm lost! any suggestsion would help!

I may have solved this -- maybe -- by reinstalling Mavericks. Two days after the re-install (which was easy), the sleep function seems to be working properly.

What cable do I need to move files from my macbook pro 1,1 (2006) to my new (late 2011) macbook pro?

I am trying to migrate everything from my macbook pro 1,1 (2006) to my new (late 2011) macbook pro?, what cable do I need? I have now bought the wrong one twice...!
Thank you!

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 stuck at spinning wheel of death after a Thunderbolt issue, HD erasing and fresh Lion install from Recovery HD. Please help me!!!

So, I think the title says it all, but to give you a little more info:
I connected my late 2011 MacBook Pro to my TV using a Thunderbolt HDMI adapter, and closed the lid. When I opened it, it wouldn't show the login screen, so I restarted using power button. Got stuck at the Apple logo with the spinning wheel. So I booted the Recovery HD and found out it was a HD problem, so I (reluctantly) erased the HD and installed Lion from scratch. When it rebooted (after DOWNLOADING the Lion components) I got some terminal commands (sorry for not being more specific, still a noob when it comes to Mac) and then the screen faded and a message appeared saying I needed to reboot the computer. So I did. 3 effing times. Then I got stuck AGAIN at the spinning wheel, and I'm currently with that on my screen. I'm trying the forums before calling Apple (my computer's still within the 90 days of warranty) because it's not yet 9 A.M. where I live

can you go back to recovery mode then open disk utility.
in disk utility, higlight the disk, the one saying the brand and size then click on repair disk under first aid tab
if it repairs fine, that's okay
if repair was not successful, go to partition and change current to 1 partition then apply
install lion again
hope this helps

13" late 2011 MacBook Pro has frozen after Yosemite installation. I can, however, boot from a clone of my MacBook Air that is on an external drive. Despite the fact that I can boot from the external, could it be the RAM that's the prob

My daughter's 13" late 2011 MacBook Pro has frozen (null sign displays) after Yosemite installation. I can, however, boot from a clone of my MacBook Air that is on an external drive. I reinstalled Yosemite on the MBP HD, but it still hangs in mid install. Despite the fact that I can boot from the external, could it be the RAM that's the problem? I'd happily put 8 GB in if it seems probable that would solve the problem. I've tried all the suggested procedures that I've seen posted here. Disk Utility, and my older version of DiskWarrior indicate the HD is OK. I have DiskWarrior 5 on order.

Boot the MBP with the OPTION key down. If successful, you should see two HDD icons, Select the recovery partition (on the right).
From the 4 option menu select Disk Utility.
Run Disk Utility>First Aid, Verify and Repair.
If the disk cannot be repaired, it will have to be replaced.
Ciao.

Late 2011 Macbook Pro suffers from screen corruption on wake up

Hi I wanted to let you know that the hard drive is bad I am meeting with the apple manager tomorrow since my laptop is no longer under warranty but I had previously brought the laptop in for the same black screen when the warranty was good.. Have any pointers on how to approach them ? I'm seriously disheartened by this especially since my 2006 white MacBook is running like a champ with no problems ever which is why I decided to buy another MacBook but one that was capable of running Lion

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!

Hi i cannot change the brightness on my late 2011 macbook pro.

Hi i cannot change the brightness on my late 2011 macbook pro. It is stuck on the lowest level in which i can't view the screen without a flash light. Please i need help how to solve this. I was on my computer when i checked the back which it was really dusty, i tried unscrewing the bottom however some screws were too tight so i took it upon myself and got a rod and startedremoving the dust off the vents and i may have clicked something as i closed the lid on the macbook i could hear the sounds still from the film but the lid was closed as i opened it back up the brightness was on low but sounds were still playing. All the buttons work , all of the F keys, apart from the brightnes keys. I can shine a tourch on the screen and see the display but the brightness will not change but i can see when i click the brightness it says it changes. I have connected it to a spare tv i have via hdmi and i really need help as this is my primary computer and i need it for work when going away. Thank you

Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

Late 2011 Macbook Pro iPhoto 9.2.2 Graphical Glitch

Please see the following video I have posted on youtube. The problem is happening on the late 2011 13"inch Macbook Pro with intel 3000 HD graphics. The problem is limited to iPhoto window. Is it a faulty GPU? or a Software problem?
https://www.youtube.com/watch?v=b9m1FD6MYs0&feature=youtu.be
Any feedback will be welcomed.
Thanks

If anyone has the same setup. Then I would love to know if you have the same problem. I have included the steps that recreate the problem. I have sent a bug report to Apple about this, but I am still not sure if this is a hardware issue or a software one.
I believe this glitch is specific to the Intel 3000 HD graphics card, as I am unable to replicate the problem on a Mid-2009 Macbook Pro or a Late 2009 iMac.
My Setup:
A) Late 2011 Macbook Pro 2.4Ghz with Intel 3000 HD graphics.
B) iPod touch 4th Gen 8GB, Original iPad 16GB, SDHC 4Gb Card
I have been able to replicate 3 times out of 5 this glitch by following these steps.
1) Connect your iPod touch or iPad or SDHC card to your Macbook Pro.
2) Wait for iPhoto to launch.
3)Once iPhoto is launched. Select iPhoto from the Menu bar and click EXIT iphoto.
4) Relaunch iPhoto since your iPod touch or iPad or SDHC card is still connected, iPhoto will show you device photos first. Deselect that by:-
5) Clicking on Photos option under Library and then hovering mouse over your Photos. The glitch should show up.
6) Quit iPhoto
7) Relaunch iPhoto
8) Deselect Device photos by clicking on Photos under Library
9) Hover mouse over Library Photos. The glitch should be still present.

Late 2011 MacBook Pro can't boot after Yosemite install

After installing Yosemite on this late 2011 MacBook Pro it stops about a third of the way into booting up. It displays a null sign. I can boot into recovery disk, or external HD (I don't have a backup of this system, but can boot from my MacBook Air's clone) if I use option-R or just option at startup. It won't go into Safe Mode. From the ext HD I have reinstalled Yosemite on the MBP, but it still freezes mid-boot. Disk Utility repair permissions, repair HD, zap PRAM, SMC, I've tried all of these (from reading advice here, and PM from Ogelthorpe). I have copied the Etre Report below. Suggestions?

Drive Partition and Format
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Quit DU when it is finished and return to the installer. Install Snow Leopard. Download and install Mac OS X 10.6.8 Update Combo v1.1.

Late 2011 Macbook Pro green pixels on the screen where dark colors should appear.

I have a late 2011 Macbook Pro I bought it new with 4 gb of ram. About 4 months ago i purchased 8 gb of pny ram for this model and upgraded the ram. I followed all of the safety precautions and discharged my static electricity before upgrading. It increased the speed of my mac and helps with certain tasks. About 2-3 weeks i notices my mac froze and strange green black and pink bars appeared on the screen so i hold the power button to shut it down and it solves the problem this will happen about once a month but otherwise my mac works perfect. Now about a month ago I powered my mac on and low and behold The screen was covered in green pixels. I tried rebooting twice and it didn't do anything then i let it sleep for about 5 mins opened my mac and the green pixels were gone. Now my mac is still usable and everything works its just sometimes like once in a while ill get a few pixels and closing and opening my mac fixes it. I was curious if this was related to one another or is my mac just starting to die....

I have been getting green pixels/boxes the last while...
I have noticed it after waking the machine from sleep. Not 100% sure if that is the only time it happens. It goes away after a few seconds, typically.
Any idea what is going on?

Purchased a used Late 2011 Macbook Pro and cannot get find my Mac to work. What do I need to do?

So I purchased a used late 2011 Macbook Pro from a friend. I am trying to get the find my Mac app set up but it won't let me because I believe he still has it as one of his devices. I texted him a couple days ago to ask him to remove it, but it doesn't seem he has or is in any rush to do that. I was debating re-installing the entire OS to give myself a fresh start. Will this give me the ability to set my computer up on the find my Mac app or is it tied to something more than the hard drive/OS.

I actually think I will be upgrading the hard drive size. So to confirm, when I reinstall the OS on this new hard drive, I will be able to add this as my own device within the Find my Mac app?
Yes, after you zero out the drive.
Which os is installed?
Just out of curiousity, what happens on my friends end to this device?
It's your friends problem not yours. Your friend will have to get his "Find my Mac" app.

Sorry ... I read but was unfortunately distracted from your original post. You have a system that came with Lion. The Lion that is on your system is only for your computer and cannot be downloaded from the app store again because you never purchased it officially through the App Store.
Try this for making an external USB/DVD copy of Recovery on an external disk. internet is still required for reinstall, though, I believe: http://support.apple.com/kb/HT4848. But at least you have a separate Recovery Partition if you ever need a fully new and empty internal disk.
Your assumption is incorrect. Although he may not be able to download it from the App store he can download it directly for the Apple servers using the recovery partition on his original drive.
All you have to do is start the install routine and then point the install to an external hard drive. Once the download is finished the computer will reboot to start the install. At that reboot disconnect the external drive so the install can not start. Boot the computer back into the OS on the internal hard drive, which is what will happen automatically once the external drive is disconnected. Then connect the external and copy the files from it that were downloaded. Right click on that downloaded package file and select Show contents. In the contents of that package is a file called InstallESD.DMG. Copy that file out of the package and burn it down to a DVD or USB thumb drive and you now have the Full Lion Installer. I have several of them laying around on different hard drives and 2 USB thumb drives which I have used to reinstall Lion on my 15" MBP.
Sorry OP I should of just typed this out in my first post.
