Macbook Pro Early 2011 13" RAM Issues

Hello everyone,
About a month ago I realized that my computer was running extremely slow. After further inspection, I found out that somehow 1 of the 2 RAM sticks had come loose. I'm not quite sure how because I have never dropped my Macbook. Anyways, after getting this fixed at the computer store at my university, I realized that everything was working fine. However, today I noticed that there is another issue. As you can tell by the attached picture, it says that there is 4 GB of RAM installed even though it says that one of the slots is empty... I'm not quite sure what to do about this besides taking it to the Apple Store, but I would definitely prefer to not have to do this since my warranty has expired. I've been planning on upgrading to 8 or 16 GB of RAM, so if there's no other fix to this problem then I may have to go ahead and do the upgrade sooner than I thought.
If anyone has seen this before and knows a solution that would be great! Thanks!

I would run the Apple hardware test (use the extended test) to see if it identifies any hardware issue.

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

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.

Maximum RAM for a Macbook Pro early 2011 15 inch?

What is the maximam amount of RAM for a MAcbook PRo Early 2011 15 inch?
I have 8GB now, but I wanted to go up to 16GB. SOme have said not possible, others maybe.??

You can check for yourself
OWC your other best bet http://eshop.macsales.com/shop/apple/memory/

Will Windows 7 Pro run with 16GB of Ram in Macbook Pro Early 2011 13-inch?

Will Windows 7 Pro run with 16GB of Ram in Macbook Pro Early 2011 13-inch?, Does the brand of the Ram matter ?
I installed Crucial 16 gb and the Mac runs just fine but Windows won't start. It gets to the login screen then it turns white.

I decided to make another try today after some reading and googling the internet.
I started windows with my old 4GB memory and changed the bootconfiguration with msconfig. I typed manually in max memory tp 16384 MB and saved the settings. Then I turned it off and inserted the 16GB ram again. Then it started really but when looking at the properties of my computer it says 16 GB installed but I can only use 2,16GB. So I opened msconfig again and changed the settings once more and restarted. Now it says 16GB installed but I can use 14,2GB so I guess it is ok now for some strange reason. I suppose the lost 1,8GB is for the system ?? Do I dare to turn it off again :-) what will it say next time ?
I am so happy and greatful for all your help, I really really appreciate it and I hope my solution will come to use for someone else with same problem.
Thank You all :-)

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.

Upgrading ram on macbook pro Early 2011

I have a 13in macbook pro early 2011 and need to upgrade my ram from 4gb (2gbx2) to 8gb (4gbx2). I have been looking online and found a lot of bad reviews for recommend brands and wanted to know if anyone had any suggestions.

AriMack13,
RAM from Crucial and OWC have good reputations with Macs. I’ve used OWC RAM myself, which comes with a lifetime advanced replacement warranty.

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 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:
OS X Mavericks: If an app freezes or quits unexpectedly
http://support.apple.com/kb/PH13975
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
Restart your Mac in safe mode.Start up in safe mode
Use Disk Utility to repair your computer’s internal disk.

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.

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.

Will a Macbook pro early 2011 installation disc work on a 2007 or 2008 Macbook pro 15

My collegue's 2007 or 2008 Macbook pro 15 inch keeps getting stuck on the apple load up screen everytime he hits the power button. He doesnt know what version it is and I forgot to write down the model number of it(Ill update May 16 at 10am PST). I tried safe mode, it worked but after the loading bar gets close to 1/2 it freezes up. He can not find his installation disc that came with the computer. I have mine but its for Model # A1278 I think its snow leopard. Will the installation disc and application disc run successfully on my collegue's 2007 or 2008 Macbook pro?
I apologize if there's a similar thread out there, I couldnt find one. -

Will a MacBook Pro Early 2011 installation disc work on a 2007 or 2008 MacBook Pro 15?
No it will not.
Machine specific gray/back disks are for one model of Mac only as they only contain hardware drivers for that model, not previous ones.
The 10.6.3 white Snow Leopard retail disk will work and it's available from Apple online for a small charge.

This is indicative of a problem with the boot drive and the file structure retaining data on the drive.
The progress bar progressing and stopping means the fsck drive repair is failing, likley the drive incurred head shock damage at that point.
The boot drive itself is likely fine and the problem can be resolved but the disks are going to be required if it's running Snow Leopard.
First get the disks, then attempt Disk Utility > Repair Disk and check the SMART status if the drive is still good.
If there is no backup of data, get that off the machine using a external boot drive.
To fix that problem of a bad sectors, unfortutly the entire drive will need to be Zero Erased (security option > zero all data) using Disk Uility while c or option/alt key booted from the 10.6 disks (using a wired or built in keyboard), it's the only way.
This means all programs, files (remaining) and OS X will be removed in the process. You could replace the drive also.

Installing RAM in a 2011-2012 MacBook Pro
There is really only one way to install RAM into a 2011-2012 MacBook Pro and while there are hundreds of DIY videos online, I just like this one, found on YouTube, by “macmixing”.
Note that there is a difference in the RAM that should be used in 2011 and 2012 models.
2011 models must use:
•204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
And 2012 models must use:
•204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM
So here's the video:
Remember that the 13", 15" and 17" 2011 models (early or late) and the 13" and 15" mid-2012 non-Retina models can handle 4GB, 8GB or (unofficially, but, believe me, it works) 16GB of RAM. There are, in my opinion, only two 100% Mac-compatible vendors out there: Crucial and OWC. I really can't recommend any other brands, even though it may work, as these are the only brands that I've personally used in quite a while. Also remember to stay away from any RAM that is a “value” brand - Macs are picky about RAM and often these value RAM modules just don’t work very well.
Good luck,
Clinton
