OS X :: Blue Screen With Dual Monitor / MBP Updated From 10.5.2 To 10.5.4
Jul 6, 2008
My MBP was updated from 10.5.2 to 10.5.4 (combined update) this morning and, after the installation finished, it rebooted into a blue screen. I restarted it several times and always went into blue screen.
Now, the interesting part is that this is not the "blue screen after install" problem others are experiencing. If I disconnect the external monitor during restart and wait for OS X to start everything works fine. After OS X starts properly I can even reconnect the external monitor and it works fine. In fact I am writing this post from my MBP using the external monitor right now.
Since some document on the Apple Support website was suggesting to remove the file ApplicationEnhancer.bundle in System/Library/SystemConfiguration when experiencing blue screens after the install of 10.5.4, I did look in that folder for that file but it's not there...

just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.
I've tried holding shift during startup - no effect.
I've tried rebooting NVRAM - no effect.

I have just updated my iMac G5 to 10.5.6. When I restart, it hangs on the blue screen before log in. I have restarted in Safe Mode (no problem there) and removed the APE files in the library folder, as suggested on support.apple.com. I have also repaired permissions and verified the drive. Still no luck.
Is it really possible that the computer needs hours to restart after the update? And would it be better for me to restore using Time Machine or do an Archive & Install with the Leopard discs? The computer was acting a little funky before I updated to 10.5.6 (iTunes was sluggish), but I never had a problem rebooting.

I recently updated to snow leopard and now I get blue screen on start-up.
I manage to get to enter my password and then to my desktop for a few seconds before it flicks back to my login.
I tried using disk utility from the install disc and it said HD appears to be ok. But it hasn't solved the problem.
Info:
MacBook Pro, Mac OS X (10.6.7)

I just hooked up a 2nd monitor to my early '08 Mac Pro and when in OSX the screens start to go blank/blue for about 1 second intervals. They flash together sometimes, and other times sort of independantly to each other. When the desktop comes back on it fades in like its animated rather than like its cutting in and out.
It seems fine when I disconnect one monitor.Running 10.5.2 all updates 8 core 2.8ghz with 10gb ram and 8800GT

I have a 13" MBP and it won't detect my external display. It works fine on my sister's whitebook using, but won't detect at all on the MBP. I've went to "detect displays" under system preferences, played around with the cable, and made sure the monitor is on. It work's flawlessly on my sisters. What's wrong? Any suggestion on what I should do? I'm losing my mind right now. The screen on the MBP goes blue for a sec when the external display is connected, but then just goes back to it's original desktop.

I know this is a pretty elementary question, but this is my first time using a dual monitor setup. What I would like to do is be able to browse on one monitor while watching video files full screen on another monitor. Is this possible? If so what do I need to do to make it so the smaller monitor doesn't go black once I enter full screen on the larger monitor?

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.

My dual screens are flashing, sometimes fading in and out of blue. Sometimes when they flash back to my normal desktop from the blue, everything is frozen, I can't move the mouse or do anything. What is going on with this? I have a Mac Pro Tower, OS X 10.5.4, 2 x 2.8 GHz Quad-Core intel Xeon processing, 6 GB 800MHz DDR2 FB-DIMM RAM. I use this machine to run a recording studio. It is used primarily with a Pro Tools HD3 rig.

I am looking at my 24 inch LED and wondering how one might configure a dual monitor setup with two of these. The single cable is too short for any arrangement but CPU directly behind the monitors. Not enough length to get both to the floor under my desk or with the CPU to the side of one.

Since installing SL last Friday, every time I restart my computer, SL thinks it sees a dual monitor set up. I only have one monitor. It's really getting annoying because I lose my mouse pointer in empty space where SL thinks there is a second monitor. I'm not sure how to remedy this situation.

I noticed that almost every letter has a red or blue tint on my external monitor, like behind it, as a shadow. I am connected to dvi. If I use the dvi to vga converter. It gets reduced. I even tried on a new dell monitor and it does the same thing! Is this normal? Could it be my videocard that is beginning to be defective?

I would like to use the machine to do powerpoints at our church. I want to use the internal monitor and an external monitor (projector) to do the powerpoints. I want it to work like the my iBook with the screen spanning hack installed.
if not then i will probably end up using a g3 desktop instead.

Just ordered a 17" MBP and am looking to use a dual monitor setup with an HPw22. I've tried to do some research on my own but am still unsure about what adapter I should go with as this is my first time attempting to run a dual monitor setup. Below are the specs of the monitor for the interfaces with a link to the entire specs.
Interfaces 1 x VGA - 15 pin HD D-Sub (HD-15) , 1 x DVI-D - 24 pin digital DVI

I was just wondering what someone who is a bit more knowledgeable about this would recommend getting adapter wise. Can I go with either the Mini DisplayPort to VGA or Mini DisplayPort to DVI since my monitor has both? Is their an advantage to one over the other?

I'm working with a Mac Pro (2x3 GHz Dual-Core Intel Xeon, 4 GB RAM) and a dual 23" monitor setup. Quite recently the second monitor stopped responding, after disconnecting everything, moving, and reconnecting. (Everything was boxed lovingly in its original packaging and moved by gentle movers.)
It isn't the monitors � both work fine in the first monitor port. The computer recognizes there is a second monitor attached, allowing me to access Arrangement options under System Preferences > Displays.
The power light on the second monitor comes on, blinking in the following manner (if it were Morse Code): dot dash dot....(then it is dark for about four seconds before repeating the same blinking sequence). It appears to have some sort of meaning.
Any ideas? Is there a way to reset this?

I've got a brand new macbook pro 13inch and recently purchased two of the mini display port adapters to dvi.
Figured I would setup both my external monitors 1920x1080 and have 2 + 1 monitors for working.
Only once was I able to plug both of the monitors in and have them work. Every other time (100s) the laptop crashes.
I'm able to run one external monitor at a time, but not both.
Info:
MacBook Pro (Retina, 13-inch, Mid 2014), OS X Mavericks (10.9.4)

By using boot camp, I finally managed to install XP on my Macbook Pro. I can extend the monitor but the problem is that the extended monitor is in Black&WHite and totally jagged/off centered. I tested the adater and the cable with other machine and they work fine, so definitely issue is not the cable and the adapter. I really need to use Dual monitor for some software that I use on XP, so this is really really important to me.... My MacbookPro is 2.16ghz with 2GB of RAM, and the video card is ATI Radeon X1600. Maybe I need to install different driver for the card? If anyone has done the same please please let me know exactly how you did it

I have a client with a fairly basic Mac Pro setup. He has the standard ATI 2600 graphics card connected to two 26 inch Samsung LCDs. The main monitor is ok, but the secondary monitor has about one inch of the far right side that does not work. The desktop area itself is squished in, and not chopped off. So far we have replaced the monitor with another, he has about a dozen at his disposal, we have replaced the VGA cable, and we have switched ports on the video card and re arranged the screen locations in system preferences. No matter what configuration we use, the screen on the right has it's image squished and makes many things look distorted.
Just curious if anyone else has had this issue, and what they've done to resolve it. We've contacted Apple care and they originally blamed the monitor, which is why we replaced the screen completely. At some point in the next couple weeks we may have a chance to bring the system to the Apple store, but then we'd need two monitors to demonstrate the problem.

I'm running Mac OS 10.5.6. When I plug in the external monitor to my MacBook Pro, I setup Firefox and Entourage on my notebook monitor and Photoshop on the external. I also move the Apple menu bar to the external (since PS is my main app I like having the menu bar close by). Photoshop doesn't present a problem because I'm able to switch the layout for different workspaces (laptop alone or laptop and external), but I find that Firefox and Entourage don't remember their positions.
For example, my current setup is dual monitors as mentioned above. When I get home and power up the notebook, I'll launch all the same apps. Firefox is just barely within view hanging off the left side of the screen so I'll grab the window and drag it over so I can access the green button (not sure what this is called). Entourage displays just fine. When I get back to work the next day and plug in the external, Firefox displays on the external with the window sized to fit the notebook monitor) and I'll just drag it over. Entourage loads into the external as maximized and I'll drag it over and click the green button.
