2011 MacBook pro erratic behaviour

Over the last 6 months or so, my Mac has, from time to time, decided not to properly display content. I recently upgraded to Mavericks with the hope of sovling the issue. However the problem persists.
Here is an example of the behaviour:

Hello Joshua,
Thank you for the details of the issue you are experiencing on your MacBook Pro. It looks like you are occasionally getting some image distortion.
I found an article with steps to troubleshoot issues with displays. This article is for internal and external displays, so you can skip any steps referring to an external display. I recommend reviewing the section titled "No video or no signal, image distortion, 'snow,' or flickering", but this step specifically stands out to me for the issue you described:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the full article here:

Thank you for posting in the Apple Support Communities.
Best,

15 inch 2011 Macbook Pro crashing under mild stress

I've been encountering numerous hardware problems with my 15inch 2011 Macbook Pro for the last year. Problems such as the laptop overheating before going into sleep mode when I close the lid (which caused my hard drive to corrupt). My laptop has also become extremely sensitive to being bumped. A slight bump while the machine is in use and it'll give me a ram failure 3 beep code. I've used 3 different sets of ram and it still suffers. And now within the last 2 months my computer seems unable to handle any mild processing. The system will start to slow down significantly when I open more then one tab in my web browser at a time. The system also runs extremely hot under these circumstances with the fans running at high speeds and ultimately leading to a system crash where the screen freezes and all I hear is erratic static noise from the speakers until I force shutdown. I can't even watch 1080p videos on youtube without risking a crash! I am aware of the GPU failure that is currently affecting thousands of 2011 macs that are the same model as mine. I am trying to diagnose if my computer is also encountering GPU failure. The symptoms of my computer are not the same as what others are reporting in the GPU case, but I have no idea what else could be causing it. Any help would be great!
Thanks for your time.

If your MBP is experiencing kernel panics, use these instructions and post one:
http://support.apple.com/en-us/ht2546
Without actual temperature readings, one cannot determine if you have an issue with heat. Download iStat menus:
http://bjango.com/mac/istatmenus/
Open Activity Monitor to ALL PROCESSES and set %CPU to display values from high to low. When your MBP gets hot, post images of both for review.
Ciao.

How can I connect my Early 2011" Macbook Pro 13" inch, with a generic Mini Display Port to HDMI connector, to a LG 32LD340 LCD TV, using Mountain Lion 10.8.2?

I have an Early 2011" macbook pro 13 inch (core i5 2.3ghz 4gb ram 320hdd) with Mountain Lion 10.8.2, and I want to connect it via Mini DP to HDMI connector, and a HDMI cable to a LCD TV LG 32LD340. When I had Lion OS, I had no problems at all.

If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

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

Try SMC and PRAM resets:

How do I use my mid 2010 iMac as display with mid 2011 macbook pro?

I have a mid 2010 iMac and I want to use it as a display for my mid 2011 macbook pro.
The iMac has a mini display port and the macbook has a thunderbolt port.
Does anyone know if this is possible and what I need to make it possible?
Cheers!
-Sean

If the iMac is a 21-inch model, you need to use a product such as ScreenRecycler over a network.
If the iMac is a 27-inch model, click here and follow the instructions.

LaCie Desktop Manager doesn't recognize LaCie RAID with my 2011 MacBook Pro

Hello,
I have a new MacBook Pro 17" but I am not able to use the LaCie Desktop Manager with the LaCie 4big Quadra Enterprise Class RAID. The drive is recognized by the finder via eSATA, FireWire, USB, but is not recognized by the LaCie Desktop Manager. This prevents me from encrypting the drive. The LaCie Desktop Manager could recognize the raid with my early 2008 MacBook Pro.
I'd like to know if anyone else is having the same problem with their 2011 MacBook Pro.
I have been communicating with LaCie support but he tells me that he can't check the same or similar configuration as mine.
Thanks,
Dennis

Looks like the cable is the same if you still have the 2010.

WIP: My adventures with 2011 MacBook Pro and Windows 8.1 including seconday HDD

So I've just lost about 3 days of my life trying to install Windows 8.1 (my preferred) operating system on a Late 2011 MacBook Pro.
I feel that I've learnt a lot and hopefully can share my experiences to speed a few of you along the process. This is my own experience please let me know if anything I have documented is not true and I will revise for completeness
What my initial goal was to have a dual HD set up with an SSD running both Mac OSX and Windows 8.1 (via Bootcamp) with a 2ndry HD in places of the optical (DVD) drive for shared storage.
I have tried all/some of the following:
Win 8.1 ISO from the MS site: http://windows.microsoft.com/en-GB/windows-8/create-reset-refresh-media
USB created using Rufus for Bios and EFI boot
DVD created using Windows 8.1 (can't remember how)
Yosemite USB created using: Create a bootable installer for OS X Mavericks or Yosemite - Apple Support
There are 2 main options when installing Windows:
Bios
EFI
Both have different pros and cons, which Im going to try and document here:
Bios
Full driver support via Bootcamp download
Slower (mainly boot time, not by much though)
Not quite as "native" as some may prefer
Limited number of partitions??
EFI
Fast
Native
Does not support video driver properly (no dual screen)
Audio does not work (says Failed to start device)
Here are some random facts I know
Windows DVD will only boot from optical drive when connected internally. If plugged in via external USB it stops at black screen with flashing cursor and doesnt progress
Using 5HT-2a's method on Redit (see below) and the EFI install, I get the Cx0000005 cannot find source media error and cannot install
Hacking the Bootcamp tool to create a Windows 8 ISO with all the drivers works (see link below) but when using it in EFI it crashes repeatedly during install so you never can complete the process (I think this is due to the video drivers) and therefore can't run Bootcamp assistant thus get proper trackpad support
Using lion10's method (below) for tweaking a standard Mac partitioned HD I was able to get past the cannot install Windows error ("windows cannot be installed to this disk. the selected disk is of the GPT partition style") and install Windows using EFI
Best guides/links I have found:
lion10's method:The ultimate way to install Windows 8.x in (U)EFI mode on Apple systems
5HT-2a's method: http://www.reddit.com/r/mac/comments/2fy3be/by_popular_demand_my_better_than_boo tcamp_guide/
skipsizemore's method: Can't install Windows 8 x64 on late 2013 MBP with1TB SSD
Bootcamp drivers 2 versions depending on Mac:
Older Macs: Boot Camp Support Software 5.1.5621
Newer Macs (most 2013+): Boot Camp Support Software 5.1.5640
Bootcamp Assistant Hack for USB creation on older Macs: http://forums.macrumors.com/showthread.php?t=1680652There is an additional parameter required if you are using Yosemite during code signing (-deep I think, but cant remember)

What I ended up doing (so far)
I'm not 100% sure of the state of my disk when I got to where I ended up but I had previous completed the GDisk and DISKPART methods from 5HT-2a and lion10's methods. I was using a 128gb SSD
I then decided to start from the top (as I had previous installed Win 8.1 on the original HD using DVD)
So I ran the Yosemite installer (via USB) and used the partition tab in Disk Utility to repartition the disk into 2 partitions, 1 for OSX and 1 (ExFat/NTFS) for Windows
I then booted in Bios (Windows, not EFI) using the Windows 8.1 DVD using the DVD plugged in internally (wouldnt work using USB enclosure)
Installed Windows to the partition I created (probably the 4th one)
After Windows installed, ran the Bootcamp set up program
Reran Yosemite installer and installed Yosemite
Swapped out the optical drive for a larger HD (7200rpm) and formatted it with HFS+

Plugging 2011 Macbook pro into my HDMI TV

Hello all. I am about to buy a 2011 13" Macbook Pro. My first Mac. I have done some reading on the mini display port and it's computability with HDMI. From what I've read it is also known as DP++ and it passes the signal straight through as HDMI with the use of an adapter. However, the audio is only passed through if the PC supports HDMI signaling, which I believe the 2009 Macbooks didn't. I don't know if that's since changed on the new models. I have read that you have to use an adapter then plug that into a cable with DVI on one end and HDMI on the other and then use a "y" cable for the audio plugged into your amp for sound. I have seen on a Display Port web page, what looked like an adapter with display port one side and HDMI the other, does this exist as it seems better than the DVI to HDMI approach.
So in summary
1) What's the best way to connect my 2011 Macbook Pro to my HDMI TV ?
2) Can I get the audio to the TV through the Display Port without having to use a Y cable from the Macs audio out ?
Thanks

Does the MiniDisplay -> HDMI adapter work with the new MacBook Pro (early 2011) ?

Airplay mirroring on early 2011 macbook pro not mirroring

First, here's what I have:
Early 2011 macbook pro (identifier 8,3) with 2.2 Intel Core i7 processor connected over Wifi on 2.4 Ghz channel.
OSX 10.8 Mountain Lion
Apple TV 3 (fully up to date)
The stats I've read say airplay mirroring should work fine. I can connect both machines just fine. I can stream movies just fine. I can send music just fine. I just cannot mirror my desktop. I have the icons, a connection is made, but all that shows is a blank screen. I've adjusted the resolutions with no luck. I've shut down and rebooted both machines with no luck...
Any solutions or do I have to count my losses with Apple Airplay and spend more money on a 3rd party alternative (AirParrot)?

Hi eoinodonnell,
The problem was resolved, but I have the worst answer... it just started working, and has remained reliable since. I never found out exactly what fixed it, but I would try these things:
1) Try a factory reset on the Apple TV, and make sure your Macbook pro has all the latest updates.
2) Try to repair disk permissions (better to do it from disk utility from boot menu) and reboot your macbook.
3) Backup your files and do a fresh install of OSX.
I know I performed all these tasks, and possibly more, but something along the way did fix the problem.
I hope something here works! If so, please let me know what did it.

Early 2011 MacBook Pro incredibly slow after installing Mavericks

I'm really hoping someone can help me out. As per the subject line, I installed Mavericks on day one (and learned my lesson!).
Since installing Mavericks my MacBook Pro runs incredibly slow. If I open the Mail App and Safari - it almost grinds to a halt. I have the "Memory Clean" App which I now have to run constantly (it appears to help a little) and I try to only launch one app at a time where possible, but it's not really pratical.
As an aside, my MacBook ran really well with Mountain Lion, so there's little doubt to my mind that Mavericks is the culprit.
I'd be eternally grateful for any help & advice :-)
I spotted other people advise running EtreCheck, here are my results:

CleanMyMac is probably your problem.
CleanMyMac is crapware.
Crapware is anything that purports to "optimize", "clean", "accelerate", "monitor", or "protect" your Mac. These apps are unnecessary, poorly written, overpriced (if they were free, they'd still be overpriced), and harmful. The people who sell this stuff know this, but they keep selling it because people keep buying it. They can damage your OS and be difficult to uninstall.
I would try to uninstall it, but if that fails, you may have to erase your HD and do a clean install.

I have a early 2011 Macbook pro 13 inch, I'm running Lion 10.7.4, and i want to upgrade to 10.8 Mountain Lion. Is it safe for my computer or are people experiencing problems with displays and Battery life?

Do Not post stuff about how Airplay doesnt work, because i dont have Apple TV and dont need to hear about it.

If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

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.

Screen blinking when turning on my Mid 2011 MacBook Pro after recent update.

Just did the recent software update and my Mid 2011 MacBook Pro 13" when turning on the screen blinks until the computer is rebooted/restarted. Have never had a problem before. Of course, my Apple Care just expired the end of June 2014. Is anyone else having a problem?

When you have the problem, note the exact time: hour, minute, second.
