OS X Mavericks :: IMac Start Up With Apple Logo And Sound But Then Screen Turn Off
Jun 2, 2014
This situation began when I put my Imac on sleep. After, the screen turned on in black whit the cursor but I couldn't do anything.
Then to rebooted the machine, the apple logo and sound began fine but the screen turned off, so moving the mouse the screen turned on in black with cursor.Â
I'd tried many ways, resetting the PRAM, SMC, repairing the disk and permission, analyzing hardware, repairing fsck files.
Suddenly, when I entered in Verbose mode, mi imac brought into user choose screen and worked fine, but when I shut down and tried to start my mac in the next day, it didn´t work again.Â
My 3-month old iMac was responding very slowly when I used the latest version of Safari. So I forced quit the program. From then on, whenever I turned on the iMac, it would get stuck at the Apple logo start up screen. I had to unplug the power since the machine is getting very hot after 15 mins.
besides leaving your computer on mute is there a way to turn off the startup noise on a mac? When i come late to class and want to bootup my computer, the apple startup noise draws attention to the fact that i am late and booting up my macbook.
When i start the computer and the grey screen comes up with the apple logo etc., a grey "loading" bar has started appearing in the bottom of the screen. Takes a few minutes for it to go away. In the meantime the computer gets very hot and the fans are up to 6000 rpm. Then the os starts up, and I cannot download anything, due to the fact that it thinks my harddrive is full, though i have more than 100 gb of free space.I cant even download the 10.6.2 now due to the harddrive appears to be full
I am stuck in my MacBook pro which shows white screen.
1- I tried hold C to Bogor from DVD to reinstall Mac os x , but it's not working . 2- I tried hold Shift and option to log to safe mode , but it's not working . 3- I tried reset ram, but its not working.
My MacBook Pro won't boot past the white startup screen with the Apple logo. After doing some trouble shooting my best guess is that the issue is either an issue with the logic board or the hard drive, but I am no expert so I may not be right. Here is what I have tried so far. I have done all these steps multiple times and the results have varied, but here are my most recent results:
1) First off, there are no peripherals connected so that is already ruled out as the cause.
2) When I try starting up in safe mode (holding shift while starting), the Apple logo, spinning wheel and progress bar appear. The progress bar fills about a third of the way then stops. I have left it for quite a long time and it still stays at a third of the way.
3) When running a safe boot (holding shift+command+v at startup) it gives me a " SATA WARNING: Enable auto-activate failed" message, and then eventually times out. Here is the full message:
4) Resetting the PRAM (holding option+command+p+r at startup) does the second chime but only results in the flashing folder icon with the question mark.
5) I tried booting up the computer in single user mode (holding command+s at startup) and running fsck -fy, it again gives me a "SATA WARNING: Enable auto-activate failed", then eventually times out. Here is the full message:
6) I tried booting in recovery mode (holding option while starting). When I do this I do not get the OSX utilities screen. Instead I get a white screen, sometimes my hard drive shows up on the screen, sometimes it does not.
If i boot in recovery mode with my osx install disc inserted the disc appears. If I select the hard drive we are just back to the apple logo and spinning wheel. If I select the install disc it goes to the apple logo/spinning wheel again, sometimes it allows me to start running the install, but then when it gets to the step where you select the hard drive to run the install on, no hard drives appear.
So that's where I'm at. I do not care about losing any data because luckily I backed up this machine right before this started happening.
when i start my imac it shows the apple logo, then the circle starts spinning and after a couple minutes it just shuts off. BTW i have windows on it as well so when i hold option it lets me open windows but not os
My Macbook Pro is not starting past the grey screen and the apple logo and the rolling circle. I have tried every method and I am desperate to do anything to start my computer even erase the entire disc. I have contacted the Apple store and they told me the cost will be equivalent to $600 to just repair it and no way I will be able to afford it. I am willing to do anything and even erase my entire disc. However, for that the instructions on the Apple page state that 'Insert your Mac OS X 10.4 or 10.5 installation disc'. However, I do not have my installation disc Is there any other way I can erase the OS system and at least reboot my Macbook?
I have had my MacBook for almost two years and the battery had just died on me. So I sent it back to Apple and got a new one. But ever since switching over to this new battery, my computer has had issues starting up. A grey screen fades into white and the Apple logo never appears. The computer will just stay like that for hours. A friend suggested turning the power off and back on, holding apple+ctrl+P+R, which worked. However, the next time I turned my computer on, the screen stayed white again, without an Apple logo. Can you tell me what the deal is? Should I bother reporting this to Apple? Is this permanent damage I'm going to have to go thru everytime I start me laptop? Any way to fix it? Thanks.
My daughter's old I Mac won't start. It is not backed up. We want to get some things off of it if we can. When we turn it on, we get the Apple logo with spinning wheel for awhile, then a question mark briefly and then a sky blue blank screen. Is there any hope of getting this to work? This computer is out of warranty. Does it seem that if we reinstall the Operating System we might find old data? Â
I have Time Capsule and everything is backed up on there. My data is on a separate USB HD + Drobo, but for now I need my iMac to boot but it won't. It won't even get into the Desktop. all the guides online says double click the Install Icon this and that...I would if I can get into the Desktop !
It is just stuck on the Apple Logo screen with the spinny thing, that stops spinning!
Hoping someone can help - my imac (approx 15-18 months old , intel) won't start.
Last night on shutting down DPP (canon Digital image software) was hanging and system asked me if I wanted to force quit it...sadly I had switched off my bluetooth mouse and , as usually once mouse turned off switching it back on it never re connects - why did I buy the bletooth mouse and keyboard ?, so I could not confirm yes force quit - is there no way of selecting with keyboard like there is in windows ?
So I switched off at power switch. Tried to re switch on - grey screen came up, apple logo, the little timer circle but after a while timer circle stopped and nothing further happened.
have tried several more times and now don't even get timer.
I had been using my iMac all night, when all of a sudden the bouncing beach ball appeared and everything became unresponsive, apart from the mouse cursor itself. It might be worth noting that a few hours prior to this, I plugged in an external hard drive to burn off a DVD. This external hard drive has two partitions, the first being a restored image of Leopard; and the second, my out of date backup ("yes, I know").
I subsequently restarted my machine, enjoyed the chime, pondered the excessively long start up and looked bemused at the Leopard Setup wizard. I realised that the restored Leopard partition had booted up instead of the internal disc. So, I unplugged the external drive, pressed reset on the iMac and was immediately greeted first by the reassuring chime, then by the Apple logo and a lingering grey screen and finally by a flashing dark folder icon with a question mark in the centre for eternity.
I tried rebooting a few more times. Same. I've been frantically Googling but only found the PRAM reset and a very frightening iMac disassembly guide. I've tried plugging the external drive back it, but it refuses to boot Leopard from that now. What can I do? I feel so helpless on a Mac, on a PC I'd at least be able to open the sucker up before panicking! I've been working on a client's flash web dev project for months, and not made a back up in about half that time. The website is supposed to be going live tomorrow! Luckily I have the site uploaded, but the entire source code is potentially lost, so in the long term this is a major catastrophe!
Came home from work the other day and my iMac (20" iMac from '07 / Snow Leopard) was frozen, did a hard restart and it booted up fine without much of a problem. Everything was running very sluggish so I began to verify the disc through utilities at which point it froze again, now whenever I restart I get stuck at a white screen with apple logo and something spinning underneath it. The longest I've let it sit at that screen is about an hour or so, it gets extremely hot though so I'm hesitant to leave it any longer.
I've tried a few suggestions already, safe mode with no luck, disc target onto my macbook with no luck and I've tried "/sbin/fsck/ -fy" at the command prompt which returns something along the lines of Harddrive can not be repaired. The most important thing to me right now is being able to access some of the files on there if it is not a total loss. I've back up about 2 months ago, so it wont be a total loss, but like I said, would prefer to salvage anything I can.
IT does this every time, but when I do command and r or other such keyboard commands, it goes I the recovery pahe with no problem. Whenever I tried erasing the iMac to reset it, it said the disk was locked.

Upon start up my screen goes to normal gray w/apple logo and spinner then goes black. Cursor is visible and still is moveable but nothing else. I safe booted and bar came up also but then back to black screen.Â
Why is my Snow Leopard OSX 10.6.8 IMac screen all white when I turn it on? There is no spiral and no Apple logo and the desktop does not appear. The screen is just white. Â
Prior to this, we had a wind storm in our area with some power glitches today. After one of them, the dock items disappeared and just the wallpaper was there. The colored spinner began going around when I clicked on the mouse but nothing was happening.  I unplugged it to try to reset it, but now the screen comes up all white, there's no apple logo that appears at start up and that's it. Now what should I do?
My parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.
I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.

My sisters 1GB iPod Nano is stuck on the Apple Logo Screen and will not shut off or reset by holding the buttons down. It doesn't mount or open iTunes when plugged into a computer.
Why does the apple logo briefly turn red when I switch on my Macbook Pro before reverting to grey and starting up normally? I hadn't noticed it doing this until recently.Â
My Mac was working perfectly fine until my charger broke. I ordered a new one online that took about a week to arrive. When I got the new charger the first time I used it my Mac was so slow some apps wouldn't even open. The 3rd time I had to force shutdown and now it turns on but won't pass the apple logo. My only worries are saving the things that were on my Mac, is there any way it can save it on a hard drive even tho it won't pass the apple sign?
