MacBook Pro :: Not Booting Up - Blue Then Black Screen Appearing
Jun 19, 2012
I have a MacBook Pro Core 2 Duo 2.5GHz/250GB HDD/2GB RAM that won't turn on, unless I leave the power button pressed, in which case, as you all know, the computer turns off again. It started about 3 days ago. Set the computer to sleep, shut it closed, took it to another room and opened it. The MBP gave me the blue screen, then black and then... nothing. At first I thought it was the HDD, but now I'm having second thoughts. I now think it's the cpu fan.

I just installed Snow Leopard on a white MacBook. Everything was fine until I went to Update the rest of the software on the computer. I hit "Install 11 Updates", it started installing, and then it just turned off. I powered up, hit the update button again, it began downloading and then powered off again. I plugged in power and powered up and now im stuck on a blue screen with the black spinning showing up and hiding repeatedly for 5-7 seconds at a time.

Mac starts up and then a blue screen appears and nothing else happens. After waiting 10 minutes the safeboot login comes up I put in my correct password but then it takes me back to the login again.

I recently got my laptop back after the logic board was replaced and now black lines with white text keep appearing on the screen. When this happens I cannot do anything except hold the power button in to reset.

A few times now, maybe once a month, I've restarted my (first generation, 2006) Macbook and gotten nothing but a black screen, while the computer seems to be continuing to boot in the background. The boot-up sound plays, and if I leave it to finish, the screen goes from black to a dull grey, and I'm able to shut it down by hitting the power button and pressing Enter, as if the shut-down dialogue screen has appeared. The pattern so far seems to be that if I shut down down mid-boot, by holding the power button, the next boot will still have a black screen; but when I let the boot finish and shut down from 'within' Mac OS X, the next boot works normally. I restart the computer once or twice a week, and this only happens occasionally--but it has been happening repeatedly.Â

There is always a blue screen appears after the Apple logo during the booting process. And then everything is back to normal. What is this thing? Is there something wrong with my screen or something?

I'm trying to boot a relatively new intel iMac. I can boot to a blue screen, in which all that happens is the music that happens with the welcome video of mac OS X. Â
I currently have no keyboard to do diagnostics with because I don't have the wireless keyboard that came with the mac, nor a wired keyboard. I'm planning on borrowing a simple wired keyboard to use to diagnose the mac in verbose mode and safe mode etc.Â
The owner of the mac has done a complete reinstall, hence the welcome video music, and that hasn't worked, as the screen shows no sign of anything other than blue.

I have had my macbook pro for just over 2 years. About a week ago it started randomly giving me a blue striped, grey, or black screen. The fan pins up and won't stop and either the laptop shuts itself off or I have to force it off. When it restarts it is very slow and sometimes the fan kicks on and won't stop and the screen just stays white after the initial apple and spinning wheel screen, so I have force shut it down and try again. Other times it eventually loads and lets me in but everything responds slowly and takes some time to open.

My ibookG4 is loading to a blue screen. It will not boot in safemode, so I am booting in single user made and running fsck. I have run fsck about 10 times, and it keeps saying that modifications have been made, but has not yet come back clean. I have also tried several other methods. All i've gotten is blue screen.

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.

I Upgrades to Lion last year. Two months ago, suddenly the screen of the iMac went black. I tried to boot but it didn´t. After waiting one day, it worked and i made a backup and I installed Lion again but this time not updating.It worked, never happened again till yesterday. The screen went black, I still could listen to the song that was playing on iTunes but after a while it crashed at all.Hours later could start the computer doing everything i read here: SMC, PRAM reset, start with D, with shift.... and i made the backup but when i was going to install Lion again it went black again and I couldn´t restart my iMac.I´m afraid it´s the NVIDIA card, but i can´t be withouth the computer some weeks. Is there anything i can do to fix it or to boot at least?

Just installed Windows XP using bootcamp and usually no problems switching between operation systems. Recently started using an USB modem for my wireless internet connection. Internet works on both Mac and windows through the modem. Now the problem is whenever I restart or switch on my computer, it shows a black screen if I choose windows partition to boot. No problem if I start through mac partition. If I unplug the USB modem, everything goes fine and I have to plug the modem after starting windows. Is there any solution so that I can permanently plugin the USB modem and avoid booting problem?

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

I have an iMac 21inch, Late 2009. I found after it was runing really slow that my hard drive was failing. It told me there were SMART errors on the drive. The computer is out of warranty and I'm in the middle of no where so i have no Mac store to take it to. I bought a new drive, same model, and installed it into the computer. It turns on fine, but after the Apple logo and spinning coge wheel the screen flashes, shows the blue back ground like its going to load the desktop and then goes black.Â
I've tried connecting an external monitor to it and shows up like an extended display. I've tried connecting it to another Mac, a Mini, and the Mini can boot off the iMacs hard drive just fine. If it Target Disk mode the Mini and boot the iMac I get the same flash of blue desktop then it goes black. Â
This is where it gets weird though, I'm sure your thinking, ok the screen is going bad... BUT, I boot off an Ubuntu CD, or the AHT disk and it loads fine and has no turning black. Its only when booting into the Mac OS or the installation disk. Â
One last note is that when its at the black screen and I'm sure its loaded the desktop, if I hold the power button down for about 3-4 seconds, till I hear a click. I then press the button again right away and the screen flashes on showing me the desktop and everything, for about 2 seconds... Â

My Mac froze. I tried rebooting and now it won't boot past the blue screen. I have a mouse pointer and there is a small black circle with three smaller blue dots inside of it in the upper right hand corner of the screen. Clicking on it does nothing. I tried booting in safe mode but it wouldn't boot past the galaxy screen. Again, I had a mouse pointer but nothing more. I've tried booting from the OS disc that came with the computer. It sounds like the disc is running but nothing ever happens.

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.

This only happens when I choose to boot into windows. The screen sort of hangs for about 20 seconds in a black screen with an underscore at the top left corner before even starting to boot into windows. I know its normal for this to happen for like 5 seconds tops, but this is happening for about 20 seconds and its dreadful trying to boot into Windows 7 because it takes so long. When windows is done starting up i don't even get any messages saying startup failed or something like that. This is so annoying that I even reinstalled everything but the same thing happened.

what keyboard combination did my cat inadvertently press so that I'm now seeing a black frame surrounding active areas in whatever window I'm working in. Including the text entry box that I'm typing this into? Also, various menu items are duplicated. Such as Restart Restart, Shut Down Shut Down, Log Out Log Out, etc. Where did this suddenly come from and how do I get rid of it? Tried restart. 10.5.8.

So just got my new MacBook Pro yesterday and loving it! I just got VMware Fusion and have a quick question (just don't want to mess anything up).
I have the Windows XP Black Edition image file, when I hit "Continue without Disk" on Fusion, next options are "Use installation disk image file", "Use existing virtual disk" or "Create custom virtual machine".
If I just have the .iso, what option should I go with?

My mac was being very, very slow so I turned it off, then as it it was booting it was taking ages so i restared in safe mode. While booting in safe mode the black bar at the bottom goes around 2/5 of the way across and then my macbook just switches off.Ive tried:fsckdisk utility repair/verifyreinstalling OS X LionÂ
When i tried to repair, it said i needed to erase everything and reinstall the OS. Last night when i tried to it said both drives are locked so i couldnt. And now when i just tried again, neither drivers are appearing; the box is just blank.Â
Let alone my livelyhood on the laptop, i have thousands and thousands pictures which if lost, would genuinley heartbreak me. I have much valuable data on my laptop and i really dont want to erase all data, because me being the gigantic fool that i am, i only have one time machine back up from about a year and a half ago. Â

I have a 2007 MacBookPro. shortly after installing Lion 10.7.3 and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc.When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts. Reconnecting all cables back together, I came across, what I think is the camera cable. Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem. This morning It decided to boot up. I was able to copy my essential files onto an external drive.
