Macbook Pro Early 2011 having issues

Hi all
I hope this message finds you all well.
Sorry that my first post is one begging for help but with a gig 3 weeks away i am bricking it due to the fact that my macbook pro, early 2011 has been playing up of late. It first started having problems when the L shift key became stuck, not physically but after some investigation on here I used Karabiner software to ascertain the issue and disable the key. However since then the computer hasnt run properly at all.
I have tried disk repair and so forth, also run Avast virus check but the issues still persist.
I run Traktor DJ software and for no reason the macbook has started glitching, spinning wheel of doom comes and everything slows down. I can't run simultaneous programmes and certainly can't run my Arkaos Grand VJ software at all which isn't good when we have a big gig in 3 weeks time.
I have run the Etrecheck as shown below but I dont know what to make of it?!
Can someone please give me some advice as I am stuck and cant rely on the laptop for the gig which will throw a real spanner in the works.
Problem description:
Runs slow, spinning wheel frequently, cannot run arkaos software, tractor software glitches regularly, L shift is stuck on (presently disabled using Karabiner software
EtreCheck version: 2.0.4 (89)

You have Avast installed which could be causing some problems for your Mac's operation. Use the Avast uninstaller and get rid of it.
Boot into Recovery mode by holding down the Command and R keys together and use Disk Utility there to Repair your hard drive and repair disk permissions.
Hope that helps.
As for the shift key, you should take the computer to the Apple Genius Bar and have them look at it.

MacBook Pro (Early 2011) Battery Issue

Purchased my new MacBook Pro earlier this month on the 6th. Works great & all except for 1 thing. At times or after a restart (with the MagSafe plugged in) and the battery at 100% the level suddenly goes down from 100% to 99% while the icon remains as the charged icon. I've read online a suggestion to leave it unplugged until it reaches 94% then to plug it back in & it will work (and it does) but obviously this shouldn't be happening to begin with.
Any reports of Apple knowing of this issue and or looking into it? This also happens with my iPhone 4 at times, which I got in July last year.
Thanks.

Well actually since I posted this 10.6.7 came out, which I am fairly sure had nothing concerning this situation but either just by chance or cause of installing that the thing is I haven't seen that issue occur since I made my initial post. It did happen to my iPhone 4 over night about 2 nights ago through. Was at 100 when I went to sleep, woke up the next morning to see it at 92% with the charged icon next to it.
Continuing to monitor the issue but so far, nothing on it, since the posting.
I do have a concern about the fans & the temperatures this MacBook runs at though. Compared to my old HP Pavilion DV6426US, for some, what I wouldn't consider 'power' processes, the fan kicks in, where on the HP they wouldn't. For example running 2 pages of Flash content or 1 Flash page with a game. For a while the HP ran like that, but I sprayed the fans & vents with compressed air & it hasn't since. For what its worth the Pavilion came with 1GB of RAM which I upgraded to 2GB vs the new MacBook Pro which of course comes with 4GB.

Macbook Pro Early 2011 Display issue

Hi all,
After reading the replacement program that has been extended to MBP for 15" and 17", is there going to be any news with regards to the 13"?
The reason why I'm asking is that while I'm not sure if mine is an isolated issue or widespread/common occurrence, I have had my logic board replaced last year due to a display issue, and currently still unable to run external display, despite reading up on discussion that is going on.
The symptoms mirror that of the 15"/17", just that the 13" does not have a dedicated GPU.
Hope to get more suggestions/ solutions/ news to potential replacement program from here.
Thanks all!
Regards,
Ziang

Welcome to Apple Support Communities
Early 2011 15 and 17-inch MacBooks Pro have had several GPU issues that causes graphic corruption, and it was an issue that showed in most MacBooks Pro. However, this does not apply to the 13-inch MacBook Pro, so I think it is just an issue that has appeared on your Mac but there is not a reason for a replacement program.

MacBook Pro (Early 2011) battery issues?

So I updated to Lion the day it came out, and everything was great, until today, when I clicked on my battery indicator on my status bar, it said Service Battery.
Which is weird, considering yesterday I checked and that little row that tells you your battery's health wasn't even there.
Actually, I think it appeared when I ran my battery all the way down to "empty", and I plugged it in to my power adaptor.
And that's not all, yesterday I checked my Magic Mouse battery in System Preferences>Mouse, it was 100%, and now its 81%.
And I know other people are experiencing this problem too.
I've already resetted my PRAM/NVRAM and the SMC. I downloaded iStat and it said Battery Health: 76%.

There do seem to be a lot of reports of battery problems. Don't know if there are a bunch of defective batteries or if there is some other problem. You are under warranty, so Apple should replace your battery for you since your Mac is relatively new and you are below 80% health. If you have access to an Apple Store, you can make an appointment at the genius bar and have your battery stress tested. If the battery fails the stress test, they will likely replace it on the spot.
It wouldn't hurt to calibrate the battery like leroydouglas says. The battery health percentage will be more accurate after you do that.
Good luck!

Permissions Issue on my MacBook Pro (early) 2011

I am having the following issue on my MacBook Pro (early) 2011 -
Verifying permissions for “Macintosh HD”
ACL found but not expected on “private/var/db/launchd.db/com.apple.launchd”
Permissions verification complete
Repairing permissions for “Macintosh HD”
ACL found but not expected on “private/var/db/launchd.db/com.apple.launchd”
Repaired “private/var/db/launchd.db/com.apple.launchd”
Permissions repair complete
Verifying permissions for “Macintosh HD”
ACL found but not expected on “private/var/db/launchd.db/com.apple.launchd”
Permissions verification complete
- As you can see I have Verified the Permissions and attempted to repair them; only to see the same issue pop up again.
Does anyone know how to fix this situation?
Thanks

Ignore them; they don't represent problems, and running repair permissions more than once per incident is a waste of time.

I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. What can I do?

I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. This happened once before and it was due to a buldging battery pressing on the track pad. I checked the battery and it appears to be fine. What can I do?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

I have a Macbook Pro Early 2011 from the USA. After installing Mavericks, Adobe CS6 crashes whenever it is plugged into a 27inch cinema display I purchased from the apple store in China (We moved to China). It works when not plugged into 27inch display.

I have a Macbook Pro Early 2011 from the USA. It is now running Mavericks. I connect it to a 27" Cinema Display that I bought in China after we moved to China. Before I installed Mavericks, I could run all of the Adobe CS6 and Adobe CS5.5 applications on my Macbook Pro while connected to the cinema display. Now that I have Mavericks installed, whenever I am connected to my 27" CInema display my Adobe applications crash upon opening. I know this is a rare scenario, but does anyone have any ideas how to fix this problem? Is there a new driver that needs installed? I'd appreciate any help.

I am also having a similar issue. I used Adobe Lightroom and my whole display goes black. Even my laptop screen and the lights on the keyboard go black. I can still hear the fan running, so I assume it is just the display. This is my first Mac and I have had nothing but issues. I think I am going back to Windows after this.

Macbook Pro early-2011 crashing/locking-up

Hello,
My MacBook Pro (early-2011 model 15") has been locking up and crashing lately. It was recently upgraded to Mavericks OSX.This has happened only a handful of randomn times over the past two months. I don't think it has to do with the OS version because it did this a couple months ago as stated when I had Lion, and also ML. However, in the past 24 hours i have locked up around 5 times and crashed at 3 times. I've attached the crash report below from the latest crash this morning. I use one usb port to connect to a Dell monitor using DisplayLink adapter, and the other usb port goes to a 4-port usb hub that has my wired keyboard, mouse, and phones that I test with plugged into. The mini displayport goes to another Dell monitor. Can anyone help me determine the issue? Does it look to you like the RAM has been corrupted and needs replacing perhaps? Or maybe it is this usb hub causing memory crashes from having so much stuff plugged into it? Log below:

Hi Will-H,
Thanks for using Apple Support Communities. It sounds like more isolation might be needed to rule some things out. I would recommend this article:

Disconnect any peripheral devices you just connected (for example, a printer). They may not be compatible with your version of OS X.
Uninstall any app plug-ins or enhancements from other manufacturers.If you recently updated the app or OS X, a plug-in or enhancement you installed may no longer be compatible.
Use Apple Diagnostics or Apple Hardware Test. These tools can tell you if hardware you installed, such as additional memory, is incompatible, improperly installed, or defective.Use Apple Diagnostics or Apple Hardware Test

My MacBook Pro (Early 2011) will constantly loose it's internet connection.

Okay, so I have wireless internet service which works great. I have an android smartphone, an HP laptop and a MacBook Pro (early 2011). My android smartphone and my hp computer both connect perfectly to the wireless network. On the other hand, my Mac connects at times but it rapidly looses connection. All of the wifi bars on the mac appear as if the computer was connected, but there is no connection. Does anyone know how to fix this? It's getting very annoying because I have to turn my wifi (on the mac) on and off to get internet connection again. I would really like to receive uninterrupted internet coverage on all my devices, including my mac. PLEASE HELP!

I am having the same issue. My macbook pro is one of the models from late last year. Within the past few weeks I have been getting disconnected from my wifi for no reason. It still shows that I am connected but nothing will load. When I dissconect and reconnect it loads up fine and everything works again, though in another 10 minutes it will crash again.

MacBook Pro Early 2011 - Airplay Mirroring only sends audio to Apple TV 2nd Gen

Ok, I'm stumped by this one. I have a 15" MBP Early 2011 edition and an Apple TV 2nd Gen. Airplay Mirroring from my MBP to Apple TV only transmits the audio -- the MBP will resize the screen like it's connected to a 16:9 device, and Apple TV will show a black screen like it's about to pick up the video signal, but no video transmits. A couple of times, video started transmitting, but it was about 30 seconds delayed (?!) and extremely choppy. Both devices are connected wirelessly to a Linksys router with 5 GHz (wireless N) capabilities. The router has been configured to Apple's recommendations for Airplay Mirroring.
A little more about my MacBook Pro:
Early 2011 Model ID: MacBookPro8,2
OS: 10.8.2 Mountain Lion
CPU: Intel Core i7
Processor Speed:          2 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          6 MB
Memory: 4 GB
GPU: AMD Radeon HD 6490M, VRAM 256 MB Total
This problem is driving me crazy! Airplay works flawlessly between my iPhone 5 and Apple TV, but not with a much more powerful laptop. Also, I tried Mirroring from a friend's 13" MacBook Pro, and it did the same thing.
Any suggestions, tips, ideas, etc. to get this working is appreciated!

your macbook dont support airplay mirror
He has an Early-2011 MacBook Pro, which does meet the requirements. The issue is that it is running OS X 10.7.5 and needs to be upgraded to Mountain Lion to use mirroring.

Connecting my MacBook Pro (early 2011) to my Sony LCD TV (KDL-46XBR6) and listening to Multichannel surround sound.

Dear all,
I am attempting to connect my MacBook Pro (early 2011) to my Sony LCD TV (KDL-46XBR6) via the Mini DisplayPort to HDMI. I have successfully connected the two devices and can select "SONY TV XV" in the sound preference pane. I can see and hear what I'd like, however, I can only monitor the sound in 2 channel stereo. I have my TV connected to a Sony 7.1 audio receiver via an optical cable and can monitor 7.1 sound via other sources (Blu-ray, broadcast, etc). When I go into the Audio Midi Setup utility, I am unable to configure my speakers to be anything but 2 channel stereo. I am given the options for "2ch-16bit", "2ch-20bit", "2ch-24bit" and "Encoded Digital Audio". When I select "Encoded Digital Audio", my output automatically changes to Built-in Output. Has anyone been able to successfully resolve this issue? Thanks for all your help!

You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

I have tested it with the Moshi (http://store.apple.com/us/product/H1824ZM/A/moshi-mini-dp-to-hdmi-adapter-with-a udio-support) and Belkin (http://store.apple.com/us/product/HA342ZM/A/belkin-mini-displayport-to-hdmi-adap ter) adapters, both purchased from the Apple Store with no such luck. Have you or anyone else had success with any other third-party adapters?

15in Macbook Pro early 2011 won't shutoff nor can I run disk utilities. Any suggestions?

Situation:
I have a 15in Macbook Pro early 2011 that I can not shutdown nor can I run disk utility to repair any issues. I recently had it serviced to replace a failing hard drive.
Known issues:
     - Disk Utility: Will not respond. A couple days ago I had to run it to repair some damage to harddrive. When I try to open it, it is frozen with the rainbow ball.
     - Shutdown: I can not shutdown or restart my computer as it freezes during shutdown with grey screen. I can manually turn it on and off by holding down the      power button.
     - Disc Drive: This may not be related but I can not eject DVD in the disc drive.
Any thoughts or advice would be greatly appreciated. I currently live overseas (for school) so just going to an Apple store is not really a realistic option for me at this time. Thanks

Take it back to where you had it serviced, there is usually a ~90 day guarantee
you can force a shutdown by holding the power button for longer than usual.

Macbook pro (early 2011) won't boot after sleep. Black screen with chime

I put my macbook pro early 2011 (Quad, 8 Gb RAM, 2 x SSD-disks, external 27" LED-screen) into sleep mode a couple of days ago. Everything was fine then.
However, the morning after it wouldn't wake up - this is the bootup process:
- Black screen
- Chime
- Still black screen, nothing happens.
So I've tried resetting NVRAM, SMC etc - no luck. Even tried the "Powerbutton" + "S" + Enter but to no avail.So I immediately began dd:ing my SSD-disk before trying anything else, figured it might be some preboot-corruption of some sort since I'm running FileVault2 with full AES-encryption.
Now, the problem (after some troubleshooting) doesn't seem to be disk-oriented. Remember the black screen? I've tried pulling the SATA-cables one by one on the motherboard of the Macbook pro and discovered that when I pulled the cable which reaches over the optical device (just above the SATA-cable for the optical device) then I get a white screen and I'm able to get as far as boot-option, or even disk repair (if I run my SSD-disk over USB and without any cables (three of them) attacked to the motherboard).
So since nothing works when I have disks connected or that third cable (some kind of logic board bridge? Reaches through the screen over to the other side of the mother board).
Also worth noting is that I was running out of free disk-space on my system disk. The disk is 250 Gb and free space was about 5-10 Gb (less than 5%). I also make the macbook pro dump contents of memory to disk (since my disk is encrypted it resides safely there).
So, my fear is that Apple hasn't used A-grade controllers for the disk drives (I've had drive corruption before, a Crucial 6 GB/s drive trashed less than a week before a presentation) and doesn't handle "unexpected events" nor signal/noise ratio very well. Maybe free space on disk was less than the 8 Gb needed to dump RAM (shouldn't have needed the full 8 Gb though) and this caused some kind of panic overwrite which trashed the controller?
Anyways, I've attached an image of the motherboard and I am wondering - what does the top cable which reaches over the optical drive do? Is it connected to the logic-board?

Looks to me like a fatal error on the hard disk. IMHO, the only solution is to boot from an external device, reformat the hard drive, and restore from backup. If you don't have a backup, you're in trouble. Boot from the external device, try to mount the int'l drive, and, if successful, back up as much as possible. Also, try running Disk Utility—it may be possible to fix it while booted from a different device, thought I wouldn't bank on it. At any rate, make sure to run an AHT afterwards, to check for possible hardware issues with the drive.
If the machine is still covered by AppleCare, take it to the store by all means. But they won't try to recover anything from the int'l drive, just check it, erase it if they don't find hardware issues, and re-install a fresh copy of the OS.
That's why you should always have at least 1 up-to-date backup (2, with one kept off-site, is better).

Macbook Pro(Early 2011) not turning on; Flashing Orange Light on Charger

So yesterday, I did a teardown of my Macbook pro (early 2011) in an effort to clean the keyboard because some keys weren't working. I used rubbing alcohol and As I was putting the keyboard and trackpad connectors back in, I heard the computer making a startup/shut down noise so; I realized I neglected to unplug the battery - out of fear of shock and impulse, I unplugged the battery quickly. The computer shut off and, ever since then, my computer won't turn on. When I plug in the charger; it initially gives me a very faint green light, and when I hold on the power button it changes into a very dim orange blinking light.
I've tried:
1) Resetting the SMC (No such luck)
2) Unplugging the battery; letting the charger charge the motherboard overnight (No luck)
I'd really appreciate some fresh ideas; just to reitterate, it only stopped working the second I impulsively unplugged the charger. So, can a battery die from something like that? Short circuit? Any advice would be really appreciated as I'm in the middle of finals week and really need it.

My only issue with that is that there weren't any hardware issues before i decided to open it up. I know the apple people will be very eager to charge me for something in not convinced is a hardware issue. I just get the feeling i screwed something up while I was putting it back together. I'll post a picture of my logic board soon to see if there's something obvious I'm missing
