MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

MacBook Pro won't stay awake with external display AND power connected

I've been using my MacBook Pro with an external 23" Apple display for several months, always with the lid closed and with no problems. Suddenly, I can no longer keep the MacBook awake when its lid is closed. *The AC power IS connected.* I plug in the display, close the lid, wake the system with my external keyboard, but then it will quickly go to sleep again after a few seconds. No matter what I've tried I get the same behavior.
Perhaps coincidence, perhaps not, I installed the Leopard graphics update a few weeks ago. Could this be a cause?

Apple did actually acknowledge this as a known issue with people running 10.5.2 with the graphics update, and are investigating it. There's some further discussion at this thread:
http://discussions.apple.com/thread.jspa?threadID=1394449&tstart=0
Anyway, what worked for me was powering down, connecting my external display, keyboard, etc., powering up, and immediately closing the lid. It seems to behave better now, though I haven't rebooted since, although I have switched back and forth between running with the external display, and running without it, without any problems.

Outfitting 13" MacBook Pro to Use at Desk with External Monitor

Hello, I have decided to throw out my 2007 Dell Dimension laptop and go with a 13" MacBook Pro. I would like to use the new laptop both at my desk, connected to an external keyboard and possibly mouse, plus an external monitor, and at times just as a simple laptop outside the office. I heard that you can configure it so that there would be an extended desktop, consisting of the MacBook Pro's screen plus the external monitor.
I am looking to compile a list of hardware accessories I would need to do this and for recommendations about the best hardware to get. (I suppose that the most important piece of hardware would be the monitor itself.) (I am assuming that everything would be plug and play and that no additional software would be necessary)
Any advice would be greatly appreciated.
many thanks

Steve
Do you really need 2560 x 1600?
Your MBP will deal with up to 1920 x 1200 which is pretty good on an external (say 23" monitor)
So to set up - DVI out to your monitor. Mains power in to the MBP and you can have it screen off while you work away. With no power adapter both screens will be on.
Go to System Prefs / Displays to set up your res and screen layout. You can have mirrored or extended.
Your MBP will get hot and its best left with the lid open for heat to get out. Open the lid once its woken from sleep. Startup will be with screen open. Then put MBP to sleep - close lid - wake up from the keyboard.
Hope thats what you needed!

MacBook Pro won't stay asleep, treats shutdown as restart

My MacBookPro 13" in Snow Leopard 10.6.8 will not stay asleep. In the console, I see 10/17/11 6:09:28 AM kernel Wake reason = RTC, then all the networking comes up, a few other things, and it tries to go back to sleep again - writes out to the safesleep hibernation, then, boom. Awake again:
10/17/11 6:09:49 AM kernel Wake reason = RTC
Yes, 21 seconds later.
All night long. If it's not plugged in, it's dead by morning.
Yes, I've zapped PRAM and reset SMC.
It's not always like this, but when it is, and I attempt to shutdown, as soon as it turns off, it turns back on again. In my mind, that stinks of hardware.
Anyone?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.

My labeled files on my macbook pro won't stay colored

my labeled files on my macbook pro won't stay colored

Ok, in theory you cannot lock the hard drive, so, run Disk Utlities, First Aid, Repair Hard Drive again. It should come back with a message that all is OK. Then run Repair Permissions. That often returns a lot of messages that are not actually problems, just grumbling by the system.
Then try a normal restart by clicking the apple left side of the menu bar, Restart. If you restart normally all is fine.
If not, then restart on the recovery HD again and try an Install Mac OS X and see if that succeeds this time.

New Mac Pro won't stay asleep

Hi everyone. I took delivery of my new Mac Pro a few days ago. It's the highest spec model (12 core, 64gb memory, 2 x 6gb graphics and 1TB SSD). It's connected to two 30" screens and networked to a Windows storage server.
The problem I have is that it won't stay asleep. Basically after being asleep for a couple of minutes the screens suddenly come back on and the login window appears as though somebody has pressed a key. After a minute or so it goes back to sleep and then it wakes up again and continues in a cycle.
I have tried making sure all programs are closed and nothing is running at all but it still happens.
I just wonder if anyone else has had this issue or might know a solution?

Okay thanks for all the help guys, I've discovered what the problem is but not how to fix it.
I unplugged everything but the bare minimum and the computer stayed asleep just fine. I then plugged everything in one thing at a time and tested. The culprit was one of my screens! I have an NEC Spectraview Reference 301 screen. It worked just fine on my old Mac Pro but when this screen is powered up the new Mac Pro will not stay asleep for more than 1 minute. My other screen is an Apple Cinema display and this works just fine on its own.
The solution for now is that I have to remember to hit the power button on the NEC screen before I leave the computer. This is fine but I'd love to find out what's causing this issue so I don't have to remember every time! I'm thinking maybe the NEC has some built in power settings so I'm going to fiddle with them now. If anyone else has any further ideas I'd love to hear them!

How to get new Macbook Pro Retina (late 2013) to detect external monitor via HDMI?

Hi everyone, this is my first Mac and for the most part it's been really, really wonderful.
This is my first major glitch: I cannot get it to detect my external display: It is an ASUS PA248Q, manufactured Aug 2012.
The HDMI cable according to my Amazon history is at least 1.3c from 2010, "Fanatic Digital Imperial Series Gold-Plated HDMI Cable (6 feet)".
It works with perfectly connecting an AmazonTV box to an old Samsung TV, with vivid clarity, unlike our cableTV signal.
Just in case, I have a new HDMI cable on order, which claims to be of newest standards.
The Macbook Pro Retina (late 2013) has the standard Intel Iris from the Haswell chips, as well as Nvidia GT 750M, the latter which I don't think has been used yet.
The ASUS display says: HDMI NO SIGNAL.
I have tried shutting them down and replugging the cable. I don't know what the ideal order is. The Macbook Pro is plugged into AC power, as suggested.
In System Preferences>Display, I press the Option key to select "Detect Displays" option (seriously unintuitive).
I have also tried resetting the NVRAM:
I shut the machine down. Pressed the power button, then quickly held the quadruplet: Option-Command-P-R (a double handful) and waited for the machine to chime a 2nd time. Tried to detect external display no luck.
Next, I reset the SMC:
I shut the machine down. Then I pressed Shift-Control-Option-Power for about 5 to 10s. Then I turned on the machine normally.
NVRAM & SMC steps were from an old youtube video, as the instructions I had did not explain how to do so clearly.
Please let me know if I"m doing something wrong.
Seems so exorbitant to pay $350 for Apple Care; that's a the cost for a whole new cheap laptop.
I will search the forums again. If anyone answers this, thank so much!

Hello there, willr314.
It sounds like you've covered most of the practical steps found in this Knowledge Base article:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573#1
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
The article does offer some additional links and recommendations as well:
These articles may offer additional assistance and information about displays and video adapters:
Apple Portables: How to use your computer in closed lid mode with an external display
Apple Cinema Display (30-inch DVI) has 1280 x 800 as the maximum available resolution
Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
For assistance with Retina displays, please see Frequently asked questions about using a Retina display.
If you tried all of these steps for your display and the video issues persist, contact Apple technical support or take your Apple computer to the nearest Apple Store or Apple Authorized Service Provider (AASP) for diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).

My MacBook pro won't click even with an external mouse... What do I do?

On my MacBook pro I can move the mouse pointer around with the trackpad, but I can't click or tap to click. The same is true even with an external usb mouse. Can move but no click.

The question is, what model macbook do you have, year, and OS.
Some signifigant OS upgrades from older machines have encountered the no-click occurance that you mention.
Further information is required on your model and OS you both CAME from and are currently ON.

Macbook pro(2008 later) can not recognise external monitor(NEC UXI2090) with mini-DP to DVI adapter with 9600GT

I bought mini-DP to DVI frome Apple several monthes ago and it worked well in that time until yesterday the external monitor show me no signal sign. Other PCs were connected with the same cable and monitor and they are fine. I am wondering there is something wrong in the adaptor or macbook pro. Furthermore I found the external monitor can display nornally when I switched to 9400 graphic card and used mini-DP to VGA adapter. If I switch to 9600GT no signal again. If I switch 9400 using mini-DVI, it is shown on the external screening: Out of range... In a word, In the mode of 9600GT, mac can not recognise external monitor(I can not detect it in the systerm preference even I press detect display buttun) and 9400 works in VGA mode. However when I connect adapter to mac, the screen showed blue flash.
I reseted SMC, no use; I created a new account or enter mac to safe mode, no use; so far I did not reseted PRAM beacuse of something wrong of my system. I am downlaoding Mountain Lion OS and will install it. Then I will reset PRAM and try again.
I do not know whether I shoud change the adapter or the single-link DVI cable to dual-link. Someone said it is useful in their condition. I tried some methods from BBS, such as connected when devices were off and then open, and so on. I failed.
Any suggestion for this problem?
Addition: OS: 10.7.4(Lion)

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

Macbook Pro won't connect to Maxtor external Hard drive

I have a 2009 MacBook Pro curently running 10.5.8. I am about to update to 10.6 (about time... I know). I have a Maxtor external HD that I had time machine set up on. Last time I backed up was a long time ago (I've moved a couple times, so the HD got burried in boxes). Now, I can't get my computer to recognize the disk at all plugged into my USB (don't have a firewire cable). It won;t recognize it in Time Machine even though it had been backed up many times before, and it won't show up at all in Disk Utility.
I need to update to 10.6 but I really don't want to lose EVERYTHING in some sort of freak accident during the switch. My own fault for not updating more often, but it doesn't quite matter if the computer won't recognize the disk

does it show up in disk utility at all?
Did you have a second NON time machine copy of vital data as should be the case?

MacBook pro won't boot up with the screen after Yosemite

since updating to Yosemite my Mac book hasn't woken up from sleep
i can hear it turn on when I hit the power button but no screen or keyboard lights up
really need some help please
my Mac book pro is only 2-3 years old

Hi Bizzlewood,
Welcome to the Apple Support Communities!
I know it can be both frustrating and concerning when your computer doesn’t seem to wake from sleep. There may be a few different troubleshooting steps I would suggest in this situation. Please refer to the attached article for troubleshooting information.
OS X: When your Mac doesn't sleep or wake
Your computer cannot wake from sleep
Make sure your computer isn't powered off by pressing the power key for one second.
If you're using an external display, make sure your display is not powered off or unplugged.
If you are using a Mac notebook:
Make sure the computer's battery is charged. Try connecting the power adapter to the computer, then press the power button for one second to see if the computer powers on.
Make sure the AC power cord is connected securely to the power outlet, and that the outlet it is working correctly. Confirm the power adapter or cable is attached firmly.
If your computer is plugged into a power strip, make sure the power strip is not turned off. Check to make sure other items connected to the power strip are receiving power.
Confirm the right power adapter is connected on Mac notebook computers. If a lower wattage power adapter is used than the one that came with your Mac, it may not provide enough power to charge the battery while the computer is powered on. Make sure there is no debris in the MagSafe port that might prevent charging. When your MagSafe cable is connected properly, you should see a green or orange light on the connector.
If the issue is still not resolved after verifying the above information, please be sure to follow the steps listed at the bottom of the article in the Additional troubleshooting section.
Cheers,
Joe

My Macbook pro won't stay closed, battery drains ...

As you all know the previous generation Macbook Pro latch system is not so good unlike the new models that come with a magnetic latch, is there any way I can add a magnetic latch system to my macbook pro? I know it would be a third party part, does anybody have any idea???

I am surmising that the computer is not off, but asleep; in which case the computer would wake up if the case became ajar.

New Macbook pro won't connect to older external hard drive

My old MacBook suddently died after seven years. It contained a lot of data that I had backed up on an external hard drive using TimeMachine and transferring files to it. When I hooked it up to my new MacBook Pro (released mid-2012 I think), I couldn't seem to connect. Any ideas why?

does it show up in disk utility at all?

MacBook Pro won't startup - Folder with question mark appears

I have tried multiple times to startup my macbook pro (I am not sure if I have lion or not) and it will only come to a white screen. Sometimes an icon appears that is a folder with a question mark in the middle. I have an external hard drive, but everything is not backed up.
What is going on and what are some steps I can take to remedy this problem.
I have tried Command + R as well as Shift while starting up.

Calendar on my MacBook Pro won't sync events with my iOS devices via iCloud.

I have a MacBook Pro 13" (non-retina) running OS X Mountain Lion, and an iPad 3 and iPhone 4S running iOS 6.1.3.
I recently created some events in Calendar on my Mac, and later wanted to edit them on my iPad.
The event didn't show up on my iPad, so I tried my iPhone.
Neither worked out, and I assumed it was my Internet connection.
Later, my iOS devices still wouldn't get the events from my MacBook.
I made sure all my devices were logged into iCloud with the same account and the calendar synchronization was enabled.
Still nothing worked!
How can I get my events to sync?

Be sure that the calendar on the mac is in the "icloud" group and not "on my mac". Calendars "on my mac" do not sync with icloud.
