OS X Mavericks :: Screen With Blue Background While Boot For Nearly 1 Second
Jun 26, 2014
Display flatters for up to one second while doing the regular boot.Means it gets blue with Apple logo bright - like a negative of original screen.Was not observed with Mavericks first releases .1, .2.iMac Late 2013, 27 inch, NVIDIA GeForce GT 755M 1024 MB.Again possibly a problem with SMC and it's reset as first solution candidate,or rather graphics?
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.
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.
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.
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...
Macbook Pro 13" (2011) Upon startup, displays a grey screen, then after a few seconds, the logon screen, I would logon, then it would show the Apple White boot screen, then it would ask me to log on again (sometimes)
After installing an app ('Detour') I was asked to (or it was suggested that I should) restart my computer. I did so, and now my 1.33GHz iBook G4 turns on - but it will not go any further than a blank blue screen (after the initial grey screen that appears.) Thankfully, all my data is on an external drive. I keep my music and footage which I have shot on there amongst other things. I also have a backup on my external via Time Machine of all my data which I keep on the iBook drive, so nothing should be lost.
I hardly ever turn off my Macbook unless i need to - I just close it and use it whenever i need to. I let the battery run dry as Apple suggests to do every now and again, and turned it on the next day. It started to boot and took a little longer to get past the grey apple logo and loading circle and then froze on the blue screen. I can control the mouse, but every few seconds it changes to a darker blue, cursor disappears but returns after a second or two. I've tried:
- Booting into safe mode (Same thing happens) - Booting from CD and repairing permissions (Said everything was ok, same thing happens when I booted) - Single user mode (used some commands from an Apple page and restarted)
I can however boot into windows perfectly fine, which leads me to suspect it's a corrupt log in item. I'd like to know for sure it's not a hardware problem so I don't have to take it into an Apple Store.
I have a fifteen inch 800 MHZ 768 MB ram iMac G4 and for some reason it won't boot up. The apple screen shows up, goes away and then the screen is apple-blue with the cursor you can move around. I left it on overnight and it didn't get past the apple-blue screen. What do I do?
Mbp had a kernel error and would not boot so I took it to Apple store and they said it needed new harddrive. I installed a new hard drive and 8gb of ram while i was at it.When trying to install the OS on the new hd, it would stall at random points every time, so I made another appointment at the Apple store.The morning of my appointment I managed to get the OS to install but then it froze in the setup stage so I went ahead and went to my appointment.This time they suggested it was the hd cable, so I got that replaced and the mbp was working fine when the guy brought it back out to me.When i got home i tried to install Snow Leapord, it froze, and now I cant do anything.Now when it boots I get the apple logo screen with a loading circle underneath for about 1 minute, and then it goes to alternating between blue screens, one with a loading circle and one without.I've tried all the basic bs stuff and nothing has changed?
I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this? I am using 10.6.4.
My imac will not boot past the blue screen. It crashed whilst loading a new application which I downloaded from the mac website, had to force a shutdown as it wasn't responding, and now it will not boot no matter what I try. I have searched for answers on the forums but my mac will not respond to any keyboard commands even with the installation dvd inserted. I don't get the startup chime anymore either.
I was given an ibook g4 a1133 but when i boot it all i get is the blue screen with acursor on it which i can move and nothing else.It gets past the loading osx then thats when i see the blue screen, have tried ti install linux but do not seem to be able to boot from the cd using the c key nothing happens .As I am new to macs I need some help if that is possible, so any advice would be appreciated I have no discs with it so am unable see what os version is installed or any information at all, that so far I have been able to get.
I am trying to reformat an iBook for a friend. Everything was running, but, there was no chime on boot. I logged into the machine, and was checking files and folders when it locked up. It actyally locked up while trying to run Microsoft Word. It now boots to a grey screen the the little "spinning" thing, and then, instead of going to the login screen, it just turns blue. It will NOT boot into Safe Mode, it will NOT boot to the iBook Install CD, I just get the same blue screen using both methods. I used Command-Option-P-R without success. I booted to Open Firmware and typed reset-nvram without success. I don't know what else to try. I am copying her files right now by booting into Target Disk mode, but, once I get that done, I still won't be able to boot the install disc to get the system wiped and reinstalled. What else can I do to correct this?
Last week my macbook pro started have gray or blue screen problem, it won't boot all the time I turn on, instead I will turn into gray or blue screen and won't do anything else, the OS is to the latest version, and if it start normally it goes blue or gray screen everytime I use final cut pro, I mainly use this mac for editing videos, I try everything like safe mode, I even format the hard drive but the problem still there...
I have been getting blue screen which flashes about a second (once) at the start-up apple screen, but it is not stucked, it jumped to log-in screen immedaitely or rather normally. However I do understand that it should not be a normal start-up because when I just bring this mac home I do not have this problem before.

I have a 2009 2.53ghz 8gb 500gb 7200 macbook pro, running latest version of snow lep 10.6.4. It's been running fine since I got it last august, now today I started it and I get the blue screen that seems to refresh itself with a slight flicker every 10 seconds with a new blue screen with the spiraling activity dots. I tried booting from a disc, and it nothing changed. I tried booting in safe mode and it the bar would fill up, then it goes right back to bluescreen. I don't have a screwdriver on me, so I can't take the battery out.
Everything was fine until this morning when i came into work, started up my Macbook as usual from sleep mode. was able to use OS X for a little while, had to leave to go onsite so i locked my screen (i use sizzle keys and made Command + L to lock my screen to the log on prompt). as soon as the cube spins to the logon screen, BOOM, all i see is the solid light blue screen just sit there. i walk away and 5 minutes later, it's still on there, can't recover or go back to my desktop, so i force shut down (hit the power button, and attempt to reboot the OS X. then thats when it all gets bad. Everytime i boot into OS X it just sits there with the blue screen and flickers back and forth with the gray gear wheel spinning and so forth.
Ok, so next check, i go to boot into my Boot Camp partition into Vista. no problems, was able to boot in my boot camp partition without any problems (im typing this in boot camp at this moment.)
So far i've been able to boot into my Boot Camp and the OS X Restore Disc without any problems.
I booted into the OS X boot disc, and ran Disk Utility, ran the perrmissions check and the disk check and both fixed problems aparently on my OS X partition. went to boot back into OS X, blue screen.
So now i do the PRAM and NVRAM reset doing Command+Option+P+R and again booted into OS X. blue screen.
Booted into Safe Mode (Safe Boot) took awhile, but again. stuck at blue screen and if i press any keys or move the mouse, the grey gear spins for like 10 seconds and just goes back to the blue screen. and the process goes over and over again.
(later on this afternoon) I even ran FSCK to check the volume for problems. "it appears to be OK"
The good thing atleast in this situation is that i can access my OS X partition in Vista (via MacDrive) without any problems, so if having to reload my previous Time Machine backup (which stupid me forgot to back up my system over 60 days ago ) or having to just Archive my OS X and reinstall it, that will have to be my final choice. But i don't REALLY want to have to do this all over again if at all possiable.
My parents bought my younger sister a new MacBook a couple of days ago. She wanted me to install Windows on it so that she could play some games that she has.
So, I ran Boot Camp assisstant and installed Windows XP. XP itself runs fine. However, when I put in the disc from her MacBook that installs the Boot Camp drivers it gets to about Cirrus Audio (or something) and then crashes to blue screen. I tried installing the drivers a couple of times and then tried to reinstall XP and try again.
At first i get the white apple logo en the round indicator and then the screen turns blue/turcuse and it takes aprox 10min before i see the desktop. Its fast but not very fast to boot into safemode. When the computer is all booted up everything work great!
Ive tried to reinstall Snow Lion after i formated the drive but without any luck. Ive resetted SMC and PRAM. The superdrive has stopped work to, when i insert a disk i spinnsup for a min or a half then it ejects the disc.
I installed snow leopard now thru a external dvd via usb. AND! I almost forgot, the computer doesent get out of sleepmode after i closed the lid,

I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?
some reason my Macbook Pro 15' inch won't start up. It's stuck at the blue loading screen after the gray Apple. The screen switches from two blue colors every 5 seconds or so along with a loading symbol. Sometimes I can see my mouse and use it, but that's all what is happening. The last thing I did was installing the newest video driver on my Boot Camp. (Windows 7 - 32bit and Leopard 10.5 for mac) I can still start up Windows 7 without a problem on Boot Camp, so it doesn't seems a hardware issue. I already tried some stuff found on the internet, but I can't start up 10.5 in normal or safe mode.
Won't boot up past this screen, this is the first time this has happened. I am fairly certain it is related to an attempt to install SP3 (I had removed it in favor if SP2 to hopefully fix some wireless issues). I noticed when I shut it down last time that it was installing updates, which most certainly included SP3, and then I left the computer. Maybe the install failed? If so, how can I fix this? Any way around other than reverting to a backup? (I think the clone I have of it has SP3 on it)
I have a 2.0 GHz early 2005 Power Mac G5 (7,3) that won't get past the light blue screen at start-up. I've tried everything - reset the PRAM, Apple Hardware Check (on overnight loops, everything came back OK), fsck (all OK), repaired my HD and permissions on it, and then erased the drive using Target Disk Mode and another Mac, and attempted to reinstall OSX from the install disk that came with it (with OSX Tiger). I've tried switching out the RAM with no luck.
The only thing I haven't tried is a new video card (the installed one is an ATI Radeon 9600). Here's what it does: powers on with the usual chime, then moves on to the white Apple screen, the wheel spins, then it moves on to a darker blue screen, then it finally moves on to a lighter blue screen with an arrow, and it just stays there. It will boot into safe mode (pressing shift), but I can't even upgrade to Leopard in safe mode, much less figure out what's wrong.
