Blank Screen With Apple Logo Problem
While watching a movie (.AVI, ~400MB, Normal Resolution) with OPlayer,
i got a black screen with the apple logo.
I pressed the round button on my ipad2 several times.
After 30-40 second i saw my "desktop" (not to the oplayer).
This happened 2 times.
Any idea????
Thanks.
Try restarting your device or do a hard reset ie hold the power and home buttons simultaneously until the Apple logo appears — a restart is always the first option if anything goes wrong.

MacBook will not start. I have restarted with original CD. I have used Utilities and "no problem" with hard drive. I have reset PRAM. I have tried safe boot. Nothing is work. Gray screen with Apple logo and rotating wheel. Thanks for any suggestions!
Snow Leopard is a Mac OS X version. You say that it's the version you have in your Mac (10.6.8). Do a back up of your files, format the hard drive (using Disk Utility) and reinstall again

i upgraded to yosemite last week, now my computer wont start. it stops at white screen with apple logo. what do i do?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -

White screen with Apple logo/ not booting
I recently tried to install the software for the "Flip" video camcorder and upon restarting my computer after installation, my computer is stuck on the white screen with Apple Logo, 'thinking" wheel spinning, and fans going full blast. I tried forcing a stop with turning computer off by holding power button in the back until system powered off. When I started the computer back up, it did the same thing.
What is the likely problem and how do I fix this. I bought the computer used and do not have the OS X software that comes with the computer originally.You really need those discs. You can either buy a BLACK retail version of Leopard and use that or you can call Apple at 800-767-2775 and for a nominal fee they will send you the proper discs for your model. You will need the serial number, which you can find on the bottom of the foot of your computer. Do not buy any grey discs, they are machine specific and will not work on yours. In the meantime, try starting by resetting the PRAM and the SMU
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.
You need to make sure also, that the software that comes with your Flip is compatible with the OS version you are running.
Let us know how you make out, -
Computer doesn't boot, stuck in white screen with Apple logo
I got a friend that has a MacBook 2.0GHz, Black. The computer had some sort of problem so he took out the HD and placed it into another computer (MacBook 2.2GHz, Black). For some reason whenever the computer boots, it gets stuck in the white screen with the gray Apple logo, and shows up a bar, as if it's loading some sort of firmware update. It never advances, and it doesn't go thru.
If he takes the same HD and puts it into an enclosure, first it would take a while to mount in another computer, and afterwards it would give some errors, but now it doesn't even load.
Before he had the issue with his original computer everything was working fine, and there was no update going on when the computer got broken. The problem that that computer has isn't related to the HD.If you have physically removed the drive and connected it to another computer and it "took a while to mount" then it sounds like the drive itself is failing. Hopefully he maintains backups.
Boot the MacBook in "verbose" mode (press and hold down option+v while powering up)
http://support.apple.com/kb/HT1492
In this mode you will see all the boot messages scroll by instead of the typical white screen with Apple logo. You will likely be able to see messages indicating what the computer is trying to do -- for example messages indicating that having failures or retrying to read the hard drive.
The access arms on hard drives have to be precisely located above the "tracks" on the disk in order to read data. As the drive ages & wears, the accuracy of the arms can become sloppy, causing the read/write head to no longer be precisely located over a track. This results in failure to read correctly. Most drives have a useful life of about 5 years -- after which the failure rate will go up substantially. Fortunately, replacement hard drives are cheap. -
Grey Screen with Apple Logo - HELP
First of all: I know there is another topic for this, but this is a different problem (i think?)
I was installing snow leopard... it came up with that green tick with restart below it. It shut down and when it booted up it went to the grey screen with apple logo and it hung there for 6 hours until I turned it off. The disc is still stuck in there (tried holding in the mouse button) and it won't come out. I also held in the C button which made the disc drive make a lot of noise.
Any help would be appreciated.Here there is a lot of topic about that subject.
By any change, have you completed all upgrade that your mac asked you before installing 10.6?
If yes, you're in this situation: http://support.apple.com/kb/TS2990 , you can try to install it again. Some people said that it took them 3 times to make it works. -
Computer won't start, grey screen with Apple logo only. Ideas?
Last night my wife's G5 froze. It is a G5 2.0 running OS X 10.4.11. I shut it down (had to use the power button) and tried to restart. No luck, just made it to the grey screen with Apple logo and spinning wheel. After a few seconds the Apple logo disappeared and a black box took its place, then the wheel stopped spinning. It was late, decided top wait until morning before trying again.
This morning I tried to start up again. This time got a warning(?) in upper left that a Firmtek item had already started. I'm sorry I didn't write this all down at the time, so I don't remember the entire message. Since there is a Firmtek card installed in one of the PCI slots I thought that might be the problem, and I pulled the card, as well as another Adaptec card that was also installed. Tried to start again, got to grey screen with Apple but this time no spinning wheel.
Opened media slot manually and inserted Diskwarrior. Tried to start with Diskwarrior but again only reached grey screen. Let run for ~5 minutes, until fans started to run and were begining to get noisy.
Next I reset the PRAM. No luck, still stuck on grey screen. Tried Diskwarrior again, this time got another message in upper left. Here is most of it -
System Failure : cpu=1; code=60000009 (Invalid pmap)
Lateset crash info for cpu1;
Exception state (sv=0x609bb280)
PC=0x000a4ad0; MSR=0x02003000 followed by more similar strings, then
backtrace terminated - unaligned frame address; 0xfc088891
So what's the diagnosis? I've had various issues with my G5s in the past, but have never had one refuse to boot with Diskwarrior before.
Thanks in advance for any help!Whew, could be many things, from RAM, (or RAM slots/solder issue), to CPU #1 being bad, (CPU#1 is actually the second one.
Does it boot into any of these modes?

Black Screen with Apple Logo randomly appears.
HELP! When I'm using my 60 gig 5th gen. ipod...I listen to a song, or watch a movie and after 2-5 the song/movie stops, and the black screen with apple logo appears. It almost seems like the ipod is just reseting itself or something. I don't understand the problem.
eMac Mac OS X (10.4.3)Hello!! I had the same issue. (with the 30 Gig) Eventually, my iPod went berserk, and kept reseting over and over until the battery died.
I did fix it. It's pretty simple, in fact. Warning: ALthough i hate to say it, you need to update to iPod software 1.1. There are several bugs with this update, see the thread with all the replys. However, it seems to be more annoyance than real issue, and 1.1 completely, utterly stoped the apple logo screen. The saving of my battery, and prevention of the resets, to me, outweighs the minor annoyances of glitches with the update.
Glitches i've noticed: holding the menu button no longer turns on/off the back light. Some videos no longer copy to the iPod, despite the fact that iTunes can play them, and the used to copy, and are within iPod's capabilities. They are generally converted with a program other than QuickTime. There are others people hae noticed, but that's all that i've seen so far.
Since you have Mac 10, simply do a software-update, and download all the neccessary software. Update the iPod.
Some videos are not likely going to copy to the iPod. This is due to the update. You need to re-encode them. If you don't want to pay for QT Pro, there's a free utility to covert nearly any video to iPod format. It's called iSquint. (do a search on versiontracker.com) I've used it a lot in the last few days, and it's great! The videos it converts seem perfectly suited to iPod, despite the update! Unfortunately, there seems to be no way around the error iTunes gives you about not-copying videos due to iPods's inability to play a video without a re-encode.
Hopefully, this will help you out!

My macbook pro 2011 shows grey screen with apple logo and want start
i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
Mac stuck on white screen with apple logo at startup
It's a few days i have this issue.
When i turn on my macmini (late 2009) it does the startup sound, but when the white screen with apple logo appears it stucks on that screen.
To solve this problem i have to unplug the power connector, when i restart it works normally.
This happens randomly, not at every startup.
I switched from normal HD to ssd HD (brand new one), i have the same problem with both HDs.
Since black outs are not good for computers i woult solve this problem.
Does anybody have my same issue or know what's wrong?

IMac G5 boots to gray screen with Apple logo only
iMac G5 boots to gray screen with apple logo only.
What I've tried:
Won't boot to safe mode.
Reset PRAM several times.
Won't boot to install disk with "C" depressed at startup.
Will boot to screen showing HD and arrow buttons when "alt" depressed at startup. But clicking HD icon and proceed arrow just goes back to the gray screen with apple logo. Note the HD icon has a blue "x" symbol.
With install disc in, will boot with "alt" depressed at startup to three icons, HD, install disc, and apple hardware test. Both HD and install disc icons have the blue "x" symbol and won't run. BUT the apple hardware test icon doesn't have a blue "x" and runs. Extended test says all hardware OK.
Finally, startup in single user mode with "apple-s" depressed goes to a non-gui white text (UNIX core?) which gives blocks of repetitive text starting "unresolved kernal trap (cpu0)...(lots of date)...latest crash.....backtrace:" My rough guide to the Mac gives me text to enter at that point but I can't input to the screen.
That's where I'm stuck.You're encountering a kernel panic.

These are often attributed to hardware problems though they can also be due to corruption of software. Since you're also encountering it with your DVD I'd tend more towards the former. Your computer seems to be passing the early stage POST tests for RAM. Apple Hardware Test also seems to be passing but [X-Lab: The Apple Hardware Test|http://www.thexlab.com/faqs/aht.html] document recommends using this in loop mode to test for intermittent problems.
Sometimes the crash logs (all the error messages you are seeing) contain information about the problem, but there's an art to reading those. -

Flush DNS Setting in Windows
In some cases, the DNS information you computer uses to connect to the Internet needs to be reset. Follow these instructions to flush your Windows DNS information:

On the Start menu, click Run.
In the Open field type cmd and click OK.
In the resulting window, type ipconfig /flushdns and press Return on the keyboard.
You should see a message that the DNS Resolver Cache has been successfully flushed.

On the Start menu, point to All Programs > Accessories and then right-click Command Prompt and chooseRun as Administrator from the shortcut menu. If Windows needs your permission to continue, click Continue.
In the resulting window, type ipconfig /flushdns and press Return on the keyboard.
You should see a message that the DNS Resolver Cache has been successfully flushed.
Note: If, in the command prompt, you see this message: "The requested operation requires elevation", close the command prompt and repeat steps 1 and 2 above to be sure that Administrator privileges are used to access to Command Prompt.
