Macbook Pro 2011 clamshell mode broken by latest software update?

After installing the latest MacBook Pro software update and EFI update through Software Update in the evening May 4, I am unable to enter clamshell mode any more. It used to work before. After waking up in the clamshell mode, the machine promptly goes back to sleep. On subsequent attempts to wake up the system, the laptop itself appears to wake up (at least the sleep light stops blinking) but the display does not even wake up. I can still work with external dsisplay with the lid open but this is highly annoying. I have reset the PRAM with no effect. The machine is a 2011 MBP, 15" inch, 2.2 GHz quad i7. Keyboard and mouse are wireless Microsoft desktop but the problem is also present with wired peripherals.
Does anyone else see this problem after installing the latest patch?

Okay, I'll add my frustration here as well.
I've had this problem too, and more noticable since the 1.4 update.
I posted a thread similar to this here.
But I'll just copy over what my main problem was...
Whenever I plug my computer into my Cinema Display (with the computer closed) it won't wake up fully. The status light will come on, any external hard drives will spin up, but the display won't turn on and the computer will go back to sleep.
I have to restart the computer manually to get it to work normally, and if I disconnect it while it's between the sleep and wake mode and try to open it, the backlight will come on but the screen will remain black, causing me to have to force restart it.
This is in addition to my first problem with the backlit keyboard not coming on automatically after sleep, which was temporarily fixed by resetting the SMC, but it goes back to the problem after a week or so.
What could be causing either of these problems? Could it have something to do with BootCamp since I have it installed, or is there a defect?
I would bring it back to Apple, but there's a small dent in the front right corner, and I'm afraid they would deny any problem I have.
I took my MacBook Pro (2011, i7 2.2, 17") into the Apple Store on Monday, and after about an hour of attempting to replicate the problem with a different monitor, there was only one time where there was any sort of problem.
The employee told me to see if there will be a fix, or otherwise they will replace the logic board for me.
One thing I'd like to add as a note...
It seems that the problem is more prominent when I have my computer with everything on it as usual. As in, before I took it to the Apple Store I performed a clean install of OS X, and that may be related to how bad the problem is, any opinions?
I had attempted at reinstalling OS X from a Time Machine Backup, but the problems continued shortly after completetion. In addition to this, I clean installed OS X, and manually reloaded my applications and media, hoping that the problem had stemmed from some kind of broken file system that could be repaired by a new install.
But no matter how I do it, the problem comes back despite the method. It is really something I want fixed, as I pretty much only use it in clamshell mode when home...

Hi - How do I connect an HDTV as a second monitor to Thunderbolt display with macbook pro in clamshell mode?

I have a Late 2011 Macbook Pro in clamshell mode connected to a Thunderbolt Display with the built in Thunderbolt cable. I want to then connect an HDTV via the Thunderbolt port at the back of the Thunderbolt display. I already had a cable that I thought would work which turns out to be a MiniDisplay port to HDMI cable and therefore not compatible with Thunderbolt to Thunderbolt (Mini DisplayPort not being the same technology although it uses the same port - although I'm not an expert !!) So far a web search has provided me with the only solution being using a Thunderbolt dock or storage that has multiple Thunderbolt ports and then using that to daisychain inbetween the Thunderbolt Diplay and the HDTV. The cheapest solution I can find for this would be about £250. Surely not ??!!!!
Many thanks for any comments - Nik

You could also use aThunderbolt dock with HDMI, such as:

Have an older 17 MacBook Pro, running OS 10.5.8. Software update says everyting is current. Just bought new iPhone 5S. Mac won't recognize phone, says I need newer version of iTunes. Have no problem with computer recognizing old phone or iPad.

Have an older 17 MacBook Pro, running OS 10.5.8. Software update says everyting is current. Mac doesn't have iCloud, preferences still shows MobileMe. Just bought new iPhone 5S. Mac won't recognize phone, says I need newer version of iTunes. Have no problem with computer recognizing old phone 3 or 1-1/2 year old iPad. I suspect I need to update OS, but as software update isn't telling me to do so, can I? What version would I need to go to?

Your MacBook Pro can be updated to run Mac OS X "Snow Leopard". Buy it. That will enable you to run the latest iTunes version.

Airport Disk still broken after latest software update

http://discussions.apple.com/thread.jspa?threadID=1244463
I like how the topic above was marked as 'solved' and archived. Another Airport software has come and gone and Airport disks are still broken. Mine let me copy 74GB of data to it, but refuses to show the contents via the USB port. Anyone had any luck with this after the latest software update?

I have had similar issues since upgrading to Snow Leopard. The first time, I took my MacBook to be checked and the tech said it booted up fine under another startup disk. Since it's under warranty, they just reloaded the original system (Leopard) and I needed to rely on a time machine backup. Now, after the latest software update from Apple, I had the same problem, and am restoring from the latest Time Machine backup.
Does anyone know if this is a systemic problem? Any tips on preventing a repeat the next time I need to update my system software?
Thanks.

Can running Macbook Pro in Clamshell Mode cause problems for Macbook Display?

Hi,
I recently got a new monitor (Dell U2711) and it is stunning when running at full resolution through a mini displayport to displayport adapter. However, i ran my MBP in Clamshell Mode and after rebooting (without the display this time) i had horrible lines across my screen. It was like a grid, but they were tiny, it was like i could see the individual pixels or groups of about 4. I turned it off straight away and when i came back to it (about an hour or 2 later) it was as normal.
I just want to know what is the regular behaviour of running in Clamshell? Is that to be expected? I know that Macbooks dissipate heat through the keyboard, so i wonder if it could be a heat related problem, and if that's something i should be worried about in relation to causing long term damage to my mac's display, or will it always sort itself out?
Sadly, i can't recreate the problem as i have a faulty monitor and it needs to be sent back (i will be getting the same model as a replacement though).
Does anyone have anything to say on this matter?
Thanks in advance

Is this a brand new, less then a year old, MBP? If it is then take it to a Apple care center and have them look at it.
It's a refurb late 2008 that i bought in late 2009, but i do have apple care until september 2012 i think, i guess if the problem happens again i can take it in and they can sort me out.

MBPs don't dissipate any significant amount of heat through the keyboard. No matter how often that misconception is posted, it's still a misconception.
Ok, so it shouldn't be anything to do with heat then, i know the top left corner (closest to the screen) gets pretty hot too, just above the speaker, but from Shootist007's post, it would appear that heat doesn't have anything to do with it. I mean, i wasn't running intensive tasks, i was only browsing the internet.

Wi-Fi Slow for Mid-2010 MacBook Pro in Clamshell Mode

'd like to add my experience the posts which I have see regarding slow speeds in clamshell. I have a mid-2010 Macbook Pro 13 and when I first attempted to use it with an external monitor, keyboard and mouse - I too experienced significant slowing of the wi-fi speed. About 3 months ago, we swapped our existing router (non-Apple) for an Airport Extreme. That seems to have somehow cured the problem. While this does not address the issue with a 2008 product, I'd be interested to hear if anyone else has similar experience and/or if this potentially corrects the problem for other current model (or earlier model) Unibody owners. I hope that this isn't something that might evaporate with a software update someday in the future.

Hello thedoctor8706
Reset your NVRAM and test to see if that resolves your issues. Typically that will resolve video, volume, startup disk selection, and kernel panic issues.

Macbook Pro 15" - clamshell mode doesn't work after installing Mavericks

So I've upgraded to Mavericks, but my late 2011 MBP 15" has stopped working in clamshell mode (closed lid with external display on) – display just does not detect an input after closing the lid. Anyone experienced this?

This was het same problem as in upgrade to Mountain Lion before... Apparently the NVRAM reset should fix this (PRAM-reset for non-intel based macs)
>>>
OK, after upgrading to 10.8.2 and then doing a PRAM reset gives me clamshell mode back!

Macbook Pro 7.1 not booting up after Software update

Hello everyone,
I have a problem, but first some context?
I recently got my mom's old Macbook Pro(7.1) with Intel's 2.4 Ghz C2D and Nvidia 320M graphics. A small upgrade from my 2009 MBP(5.5) but is in much better shape than my old machine. In that unit(5.5) I used a 40 GB SSD as a boot drive and a 640 GB Platter drive for general storage, and removed the optical drive, as I did not use it very often.
Well, now I transplanted both drives into the 7.1 MBP, but the system will get stuck at the grey screen. I then proceeded to backup all my data, and wipe both drives multiple times and tried to installs on a clean system.
I replaced the aftermarket ram I had with the factory sticks, put the factory drive and the Super Drive back in. Loaded up Snow Leopard via DVD on an empty drive.
It boots and runs just fine. So I put in the SSD to try it out. It loads OSX Snow Leopard just fine again. I go do a software update to 10.6.8, and on reboot to finalize, I get stuck again at the grey screen. The progress wheel freezes, and I am stuck until I do a forced shut-down.
Safe mode gets me nowhere, AHT does not work, Verbose mode freezes after 10 seconds or so and I have also reset the SMC and the NV/PRAM multiple times.
I am at a loss. I have a nearly pristine MBP that for some odd reason will not work for me in the slightest, despite my best efforts at attempting to diagnose the problem.
Note that all componenents that I listed,(SSD, Larger HDD, Upgraded Ram etc.) All worked flawlessly in my previous MacBook Pro.
Does one hardware generation make that much of a difference for an OS and for upgrades that clearly work in other Apple devices?

darkrider92,
I have the same model MacBook Pro as the one that you got from your mom. Were you able to install the 10.6.8 update successfully onto the factory drive? Were you using the factory RAM when you tried to install the 10.6.8 update on the SSD?
Have you checked the Web site of the SSD’s manufacturer, to see if there’s a firmware update available for the SSD?
You can download the 10.6.8 update outside of Software Update from Apple here; in case you need to try to install this update several times, running it from your local disk would be more convenient than waiting for it to download again.

Macbook pro (snow leopard) will not boot after software update

I helped my mom buy a Macbook Pro for herself for Christmas. Today, I connected it to her old eMac and used the migration assistant to transfer files over. It was unable to estimate migration time on the only user (after 45 minutes) so I didn't migrate the user. Then I tried to pair her macbook to her new bluetooth keyboard, but no magic happened, so I tried to use the bluetooth setup assistant, which crashed. So I ran a software update, hoping that this would fix whatever the bluetooth problem is. Despite having updated on the 23rd, there were 4 updates. None seemed applicable but I installed them anyway. Now the computer won't boot at all.
Software update said that I had to restart for the updates to take effect, so I restarted. The harddrive went whirrrrrr and the grey screen with the apple logo and the spinning circle displayed. Then the harddrive stopped going whirrrr and 10 minutes later, I started looking on the support site for what to do. I found this:
http://discussions.apple.com/thread.jspa?messageID=10564149&#10564149
Per the instructions in the last post, I fscked the drive (although -f, in accordance with the fsck help). This found no problems. The next suggestion was to boot from the OSX install disk. Only one problem-- there was a disk in the disk drive when the problem occurred and the disk eject button apparently only works while in the gui. I can't install from disk if I can't get the existing disk out of the drive.
So, any other ideas on what I can do to get this machine to boot?

Hi Jen:
Since it's new, you're entitled to 90 days of phone support (3 years if you buy AppleCare). It sounds to me like you may have some hardware issue(s) going on - you should not have the sorts of issues you're having with a new Mac. Apple will probably be much better and faster about getting you fixed than this board may be able to if that is the case.

My MacBook Pro 2011 13" is running slow after ML update

My MBP 2011 13" (4 GB RAM, i5, 320 GB HD) had been a fast machine from the day I bought it till the day I upgraded it to ML from SL. The booting takes ages, the shutting down brings in the "background task" logo and most of the apps take a long while to come up. This is really affecting my productivity with the machine. Above all, my battery standby time has also reduced by approx. 2 hours. Would really like some help to overcome these problems. Kindly help!

MacBook Pro 2011 and latest Kingston KHX1600C9S3K2/8GX

Hey guys,
As the RAM is pretty expensive when bought off Apple I decided to go with 4Gb for my MacBook Pro 2011 (some days ago).
However if anyone tries to install the latest 2x4Gb Kingston modules (KHX1600C9S3K2/8GX) 1600Mhz I'd be more than happy to know if it's a success because I might need to upgrade to 8Gb in some months.
Thanks a lot!

If you´d like to update with 3rd party Kingston´s i suggest to use KTA-MB1333/4GB
If have them running since one week without any problems
The MB within the partnumber says that they´ve been tested against Mac Books.
As you are from Switzerland here´s the link in german :

Macbook pro 2011 13" i5 slowed down, any help would be much appreciated (detailed info).

Ok first off let me preface with as much detailed information as possible, as i have read many many posts on problems and hopefully mine will be detailed enough to not cause all you wonderful people a headache.
Machine Details
Macbook Pro 13inch model (2011)
Core i5 4gb RAM 250gb Standard harddrive
As I am a very inexperienced I would very much appreciate a very idiot proof explaination, but any help I will be very thankfull for.
The laptop was running like a dream and much better than I remembered my last mac (Macintosh LC) ever did. Ive had minor hickups this last year (a trackpad that went bust under warranty and a broken power supply) otherwise its been a wonderfull experience. The final hiccup that might be a cause, not sure hence I will mention it is that my battery is Conditon: Replace Now for about a month now.
The laptop, as always was left ON, on its own connected to the wifi home network, when I returned the computer was working very slow. Any load on the harddrive/CPU. The cursor starts lagging (jumping), any keypresses are registered with a 2-10second delay. Any vidoes that i would try to play would suffer freezes in framerates/jams but audio remained fine. First step i was afraid that i may have contracted one of the new trojans so i downloaded an antivirus program, scanned the drive, but came out clean. Second step was to format the drive and perform a fresh install of OSX but no luck. Being inexperienced in Apple products i assumed that my harddrive (used to PCs) was on the fritz and went out and bought a 160gb Western Digital Black series 2.5inch harddrive. Having read all the guides and official knowledge bases on how to swap out the harddrive I did so with success. I placed in my installation OS 10.6 CD formatted the drive through the disk utility and performed a fresh install. Before doing any steps I went through the update cycle a couple of times till only the thunderbolt update remained (havent updated as I never used it). Sadly it hasnt solved the problems with cursor repsonse lag, video playback, and keyboard input lag under load.
On this install I have performed:
Verify Disk Permissions Many were found so I performed Repair Disk Permissions
Verify Disk Came up with "Appears to be OK"
performed a Pram reset (CMD+option +P +R)
My main problem is that I live in europe nowadays (Poland to be precise) and cant go to a genius bar as they dont exist, and sadly the support is a tad behind the US standards and any minor repair will be at least a 4 week wait, hence i would like to try to exhaust possible solutions before giving it off to professionals: being a month out of the warranty period has abit to do with it too:)
Sorry for the wall of text
Thanks guys for any help you could throw my way!

See the following:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

Apple has released Java updates for Snow Leopard and Lion users:

Flashback malware removal tool; available only for users of Lion without Java installed.
Install whichever shows up in Software Update. It removes the malware (if present), updates Java (if present) and tightens up Java settings for the future. You may download from Apple's web site instead of using Software Update, but it's important to know which one to get, because the other two won't work for you.

Display issue - My macbook pro 2011 detects my display but does not display an image

Hi, I am having a problem connecting my MacBook Pro (2011) to my HP 2511x display. I used the display all morning with my mbp connected and closed. When I came back, after the computer went to sleep, I cannot get any image on the display. The computer detects the display but no image appears.
I have tried-
Installing the latest firmware and software updates
restarting both the computer and monitor
trying all of the possible display arrangements and settings for resolution and refresh rates
Also I am connected using a minidisplay to DVI adaptor in the thunderbolt port.
Any and all suggestions appreciated.
thanks.

Hello Aminetti,
It sounds like your computer goes to sleep, and will not wake up, so you must manually restart your computer. I recommend the troubleshooting in the following article:
OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Reset SMC
Reset NVRAM/PRAM
Test with external devices disconnected
Try Safe Mode

Online video playback is severally laggy/choppy on my macbook pro 2011?

hey guys, got a bit of an issue here. I've been noticing some SEVERE lagging issues whilst viewing online (streaming) video, from various sites, including, novamov, youtube, and others. the videos rarely stop to buffer as i have a fast connection, but yet they still seem to lag wildly. what i mean by this, is the sound will continue as normal, the the picture will freeze sometimes for a good 5 seconds or so before resuming, this is happening increasingly more and more..
i am running Mac OSX Lion (latest Update) on my:
MacBook Pro
17-inch, Early 2011
Processor 2.3 GHz Intel Core i7
Memory 8 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB
Software Mac OS X Lion 10.7.3 (11D50b)
If it helps my hard drive space is:
Macintosh HD
Capacity: 664 GB
Available: 179.79 GB
The browser i am using is the latest version of Safari, although i have tried firefox and chrome and i experience the same issue.
I have Sophos anti-virus installed and run regular scans on my system (all clear)
i really can't think of anything else which could be causing an issue here. I haven't installed any additional software for a while, not in the time frame since the error started to occur.
I am quite surprised to be experiencing such issues as lagging on something as simple as a youtube video when my £3000+ computer handles heavy applications such as Final cut pro and Photoshop with ease...
i MUST be missing something here,
I really would appreciate any help i can get here.
thankyou very much for your time

Hey Carolyn,
Worked a treat, de-jaggy video for first time in months!!! Only point of clarification, I manually deleted the Flash plug-in before I uninstalled Flash. Don't know if this was why it worked for me rather than others but hey ...

Hi Ben...
I am quite surprised to be experiencing such issues as lagging on something as simple as a youtube video
Try troubleshooting the Flash plugin required for most YouTube video.
Quit all open browsers. I'm using Safari as a test.
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Now uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Make sure and uninstall the current plugin first.
Then launch Safari. From your Safari menu bar click Safari > Empty Cache
Now try a video.
BTW... if you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.
