No Cinema display in "clamshell" mode

MacBookPro with 20" Cinema display. After a software update (about three weeks ago) my Cinema display only functions in mirror or contiguous mode. When I close my MacBookPro the display goes black. This was not the case in the past (before update) and is quite irritating. How can I get back to the way it was?

The act of closing the clamshell puts the MBP to sleep. Wait about 10-15 seconds, then press a key or the mouse. It should wake. I have my MBP set to ask for the password to login again.
There is a new firmware update that might adjust your situation. It just came out tonight. See http://www.apple.com/support/downloads/macbookproefifirmwareupdate15.html/.

External Mac 23 Cinema Display and clamshell mode

I can get my MBP to sleep and wake up with an external keyboard, mouse when connected directly to my laptop usb ports. But if I plug in the Cinema cable to the laptop and plug my keyboard and mouse into the ports on the back of my Cinema display I can't wake up the laptop to use in clamshell mode.
Is this normal?
I would like to plug in my mouse/keyboard into the Cinema ports since all the connections from the Cinema to laptop are on one side of my laptop for easy connect/disconnect.
Now I have one USB on left of laptop and one on right side.
I know this is small item.

Many thanks!
Guess I will have to look for a compatible stand alone tuner for the monitor; buy a new monitor; buy a separate TV; or keep the computer tied up to use our eyeTV device. Any other suggestions?
The stand alone tuner to monitor seemed the most efficient in terms of us not having to buy a TV (more clutter. . .), or keep the computer hooked up to watch TV when someone else might be wanting to use the computer at the same time. Also get multiple hi-res uses for our monitor.
Oh well. Look forward to any other suggestions if there are alternatives to the above. In any case, much appreciate your reply.

24" iMac and 20" Cinema display extended desktop mode ?

I got a 24" iMac and a 20" Cinema display. I wanted to know if they will work on extended desktop mode? I didnt try to hook it up yet as I am waiting for mini dvi to dvi adapter to come.
Thanks

Hi,
according to this http://developer.apple.com/documentation/Hardware/Conceptual/HWTechVideo/index.html#//appleref/doc/uid/TP40003504
you should have no problems (you must scroll a bit down the iMac 24" section)

USB to HDMI adapter for external display in clamshell mode?

Hello.
Does anyone know of a USB to HDMI (or DVI) adapter so that I can connect an external display (with an HDMI or DVI cable) to a USB port on my Macbook air?
I need to run it in clamshell mode, mirroring the Air display. The Monoprice USB to HDMI adapter (which uses DislplayLink drivers) I tried does not work properly in clamshell mode with mirroring (though it works in arrangement mode). I know I can use the Thunderbolt port, but I need to leave this free for a Firewire device.
Thanks.

Unfortunately, I have the same problem, but using USB devices and Displaylink software. I know there are issues with Displaylink software as they say the problem is with Apple. I have three external monitors with a late 2008 I Macbook Pro which gives me four screens. I was able to get two to work + the Macbook, but there were so many issues, like you described, that I have given up and I am just using the Mini Display port which gives me one external and the Macbook. Looks like we will just have to wait until Apple does something. I have found no other solutions at this point - hardware or otherwise.

Clamshell Mode With 30" Apple Cinema HD Display

Hello,
How can I use my 17" MacBook Pro with my 30" Apple Cimema HD Display in clamshell mode (with lid closed). I can only use it in clamshell mode when the AC adapter is plugged in. When I try to wake the computer from battery, it turns on but then goes right back to sleep mode.
Thanks in advance,
Edwin

That's normal behaviour… clamshell mode will not work when your MBP is running without AC power.

HT3131 Display on to apple tv in closed clamshell mode?

Hi Can anyone help me?
When I AirPlay my MacBook pro display to my apple tv, all is fine.
However when I close the lid, (clamshell ) with mains connected, my display drops out and turns off AirPlay on my MacBook pro?
Any ideas please

Yup. I have no issues using an external display in clamshell mode. It's only when I try to airplay to my apple tv while in this clamshell mode that I run into problems. So to clarify, there are 3 devices in my situation: my macbook, my external monitor, and my apple tv (which is connected to my hdtv of course, so 4 devices). Usually I just use my external monitor with my macbook closed. That works fine. But when I occasionally want to airplay to my apple tv as additional mirrored/extended monitor, I have to open up the macbook first to exit clamshell mode. Otherwise if I just go straight into airplay while still in clamshell mode, my hdtv shows a frozen image, my external monitor goes black and I have no choice but to manually turn off my macbook. Hope that makes sense. I think it would be easier if I could draw a diagram haha.

My Apple Thunderbolt Display/Apple Cinema Display is in Disk Mode. How do I get it out of Disk Mode?

I am Leo and I am 6 years old. Me and Mommy went to the Apple Store in King Of Prussia Mall for 2 Hours. And I put an Apple Thunderbolt Display/Apple Cinema Display in Disk Mode. How do you get an Apple Thunderbolt Display/Apple Cinema Display out of Disk Mode?

Power down by holding the power button until it shuts off.

Unable to use any Apple Cinema Displays with unplugged 2011 MBP

My older MBPs have worked with Apple Cinema Displays (I currently have a few year old one and a 2011 27" ACD) while unplugged. My new 15" MBP however needs to remain plugged in to allow waking (or prevent sleeping) when hooked up to the display in clamshell mode (computer is closed). Is this a bug, a problem with my configuration, or just the way it is?
Thanks for any replies.
Jeff

Jeff,
if you want your settings to be the same plugged in while not plugged in, you'll need to do so in energy saver preferences in system preferences.
once there, you can tell your computer how to act when on battery power or when plugged in. This means telling it to not sleep even when not plugged in, or visa versa.
if you're talking about using your MBP closed while using the ACD, all you need to do is close it, and move your mouse around. it'll wake up but your ACD will become the main display with your dock and toolbar.

MBP Battery Maintenance Using Cinema Display

When using MBP in clamshell mode I read many report no easy way to discharge the battery monthly to preserve it as recommded.
I find without the power supply connected I use my 2011 MBP & Cinema Display in mirror mode with the MBP cover ajar. If wanted the MBP screen brightness can be turned down also.
Using the MBP & Cinema Display in mirror mode without the power supply connected will run down the battery in not so many hours.

NO, youre NOT supposed to do that!
There is no calibration of current Apple portable Macbooks with built-in batteries.
http://support.apple.com/kb/ht1490
There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.
Portables with built-in batteries
Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure
MacBook (13-inch, Late 2009) and later
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

Horizontal shifting bars on MBP 15 after disconnecting 24" LED cinema display and waking up from clamshell mode.

I use my MBP 15 (late 2011) with 24" Apple LED Cinema display in a clamshell mode. After disconnecting external display, and opening display, it shows horizontal shifted bars, so it becomes completely unusable. Have to hard reset laptop. Any hints on how to resolve this? Thanks.

Ok, more information for anyone that might care. The wake-up seems to be the familiar dark wake in order to go into hibernate mode. Except now, it's a death wake. Looking at the logs, I see that it happens exactly 70 minutes after sleeping, even though hibernatemode = 0 (which shouldn't hibernate at all!)
So my power settings look like this:
Currently in use:
standbydelay         4200
standby              1
halfdim              1
hibernatefile        /var/vm/sleepimage
darkwakes            0
gpuswitch            2
disksleep            10
sleep                10
autopoweroffdelay    14400
hibernatemode        0
autopoweroff         1
ttyskeepawake        1
displaysleep         2
acwake               0
lidwake              1
standbymode is 70 minutes, what a coincidence. I'm going to try setting it to 0 and see what that does.

Clamshell mode - Cinema display

I have a 20" Apple Cinema display. Can anyone confirm that plugging the mouse/keyboard into the USB ports on the display is compatible with operating the MacBook in "clamshell" mode?
Thanks-

Hi,
Do you have to set any preference in your MacBook to make this work? I had my MB connected to Gateway FPD 2200, keyboard and a mouse connected to MB through a USB port. But I could never get the Clamshell mode to work.
When I close the lid, the MB goes into the sleep mode, so I just click a mouse button to wake it up. My MB seems to be coming out of the sleep mode because it asks me to type in my password, but as soon as I type the password, the external display goes black and I see the sleep indicator on my MB blink, meaning it is in the sleep mode.
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.

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.

MacBook Pro Retina 15" mid-2012 won't boot in clamshell mode with an external display attached

I have a 15" MBPr mid-2012 running OS X 10.10.1. The system won't boot in clamshell mode (power is connected, lid shut) with an external display attached via an Apple Thunderbolt->DVI adapter. it boots fine if the lid is open. It isn't the adapter or the display since my 15" MBPr mid-2014 boots up just fine connected to the same adapter and monitor. And this system used to boot like this just fine some while ago (probably before it was upgraded to Yosemite). I've reset the NVRAM (twice) to no avail.
Has anyone encounter this? Anyone have a solution? Should I try an SMC reset (always a bit nervous about that)? Might it be a driver issue in Yosemite?
Thanks.

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:

How to keep display on Macbook Pro instead of Clamshell Mode

I have an extended desktop through a Mini-Display Port-to-VGA connection from my Macbook Pro (OSX Mountain Lion) to an external monitor. I have the Macbook Pro screen set up as the "main screen" (with the display bar on top). But everytime I close my macbook pro, the computer goes into clamshell mode and sets the extended desktop as my "main screen" which switches my display bar. Is there anyway to tell OSX ML to always keep the Macbook Pro screen as the default and not go into clamshell mode?
This also creates a problem when I want to physically close my computer to allow to sleep, but instead goes into clamshell mode and extends the desktop to my external display. Any ideas?

Re: MacBook doesn't sleep when closing lid with external monitor attached with Lion Oct 14, 2011 7:01 PM (in response to admgtz)
I would like to offer this solution. I have a MacBook Pro with an external monitor, and, for a year and a half both displays slept when I closed the MBPS. This behavior stopped when I installed Lion. They would sleep when I removed the power cord, but what a pain that would be. The command "pmset -g assertions" gave no indication of which process ought be preventing sleep.
I contacted Apple support, and after some searching, the guy working with me found this thread, which was flagged as an Apple-approved solution:

Correct AnswerRe: How do I tell Lion to disable the LCD screen even when the lid is open?
Aug 31, 2011 9:56 AM (in response to Bob_viking)
Here's the command to make your laptop behave like it did Pre-Lion (courtesy of my friend):
sudo nvram boot-args="iog=0x0"
Works perfectly for me. If it screws up your system, just zap the PRAM next boot (cmd-opt-p-r) and you'll be back to the default Lion state. Or if you can still get into terminal, this command will get you back to Lion's default state as well:
sudo nvram -d boot-args
Enjoy!
One snag was that I had to run it with the external monitor disabled, but it worked great!
