Gut white screen with flashing apple and circle/warning sign on white screen when i turn on the computer

When i turn on my computer, i get only a white screen with a gray apples in the middle, flashing, alternating with a ghostbuster-type warning. Never get to the galaxy screen. Just happened today.

Did you setup a lock code? I have done this operation via iCloud just few minutes ago and it's booted with 4 numbers lock code just fine. When you lock your Mac, it's restarts automaticly and then loads with lock screen and you are only able to enter password of 4 numbers to unlock it.

What do I do when I start my iMac I get a white screen with an apple and a moving circle?

All I get when my iMac is turned on is a white screen with an apple and a moving circle. What should I do to get the iMac to boot?

Do you have reliable backup you can restore from, as an erase and re-install may be required?
Before you got down that route, it's possible that it might get fixed if you try again. Not sure about that particular error, but I have had errors in the past that Disk Utility wouldn't fix on the first attempt but then subsequently did.
It's also possible that the (around $99, I think) Disk Warrior might resolve it - but not guaranteed.
However, I just found this thread: https://discussions.apple.com/thread/3862376?start=15&tstart=0 have a look at Nirvi's post at the end - there may be hope (I've not tried this, although it seems to have helped a few, although not everybody - so at your own risk and I wouldn't try it if I didn't have backup).

Brand new MacBookPro 13" , Stuck at White Screen with gray apple and spinning gear.
This MBP apparently didn't come with a DVD and safe mode ( holding shift at boot up ) isn't working.
Any ideas would be most appreciated.

Call AppleCare. You should not be having problems with a brand-new machine.

Bescobar23,

Blue screen with flashing folder and question mark on startup

Hello.
I need help with my Macbook Pro. I get a blue screen with a flashing folder and a question mark at start up. To date I have tried the following:
Apple Hardware (Extensive) Test (Results: "No Trouble Found")
Safe Boot
Reset NVRAM
Reinstall OS X via the internet (I received no discs when I purchased it). I select the StartUp Disk to reinstall. When reinstalling via the internet I get to a point of reinstalling Mountain Lion but it asks me to choose a drive - yet there are no drive options to choose from. Then a window comes up asking me to "Select the system you want to use to start up your computer" but no options appear. When I choose "Restart" a note pops up saying "You can't change the startup disk to the selected disk. Startup Disk could not gather enough information on the selected disk."
The only option is "Restart" from the Apple menu. When I choose that it goes back to the original "Blue screen with flashing folder and question mark on startup."
I have no Time Machine
I can't access the disc utility.
Are there any ideas as to what might be the problem?

Your hard drive has likely failed and needs replaced. That would explain why the system does not display it when you attempt to reinstall the OS via Internet Recovery.

TS1363 while updating my IOS to IOS 6 the updating process couldn't be completed for unknown reason and my iphone has nothing but a black screen with an apple and a meter that shows no progess. it completely froze!

When updating my IOS 5.1.1 to IOS 6 and after the download completed the updating of the iphone couldn't be completed for unknown error and the device froze and all i have now is a black screen with an apple and a meter that shows no progress I can't switch off my iphone or do anything!!!

Hi,
I had a similar problem last week with my nice shiny 3 week old iPhone 6. I noticed the Apple logo was on the screen, but it did not progress like a normal boot up. I restarted the phone, and it showed the Apple logo, then a red screen then cycled back to the logo and kept looping. I got the phone to the iTunes connection stage by keeping hold of the power button and the home button until the apple logo appeared then kept holding the home button. iTunes recognised the phone, and wanted to restore, but this was unsuccessful because the phone would keep looping to the red screen and iTunes failed. After loads of Apple support, I was told it was a hardware failure, and like you I live more than an hour away from the store. None the less, I made an appointment with the Genius bods, and they replaced the phone. They said they had never heard of the problem, but really, take a look at these forums and you will see that it is a common problem and I suspect they are keeping it under wraps...
My issue is that as a disappointed customer with faulty goods, why should i have to stick to an appointment to get it replaced? What other store would you have to do this?
The "Genius" didn't even want to see the phone powered up before offering a replacement... Oh, and it turned out they didn't have the exact same model as a replacement so they were going to send me out of the store empty handed.... I kicked off BIG time, and they very reluctantly gave me a phone from the sales stock, rather than the repairs stock..
Not a happy Apple customer anymore, and I feel the more people who know about the lack of service and customer care the better. They need to get off there high horse and join the real world!

Hold down the home button and the power button for about 25 seconds or until you see the apple logo. Thats a hard reset and it should restart the phone and bring it back to the slide to unlock.

Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Leopard - This will install a "fresh" copy Leopard without archiving old system files but leaves the rest of your files in place.
If you still want to restore your computer to factory level...
Start up from your install disc, go to Disk Utility and select the disk and click erase - to securely erase data click Security Options and Erase Free Space which will entirely wipe your disk, overwriting it with zeros so that no data is recoverable.
To restore read the instructions in the Mac OS X v10.5 Leopard - Installation and Setup Guide PDF

Please a simple problem but I don't know how to solve it. After installing 16 gb of ram all is good but when I turn on the computer it is a window signaling that all is correct. How is possible to delete once and for all that window? Thank you

Well then maybe you could take a screenshot because the appearance of such a window is news to me.
Also post your OS X version and what model Mac you have. The more detail, the better. Thanks.
To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot on your Desktop.
If you can't find it on your Desktop look in your Documents or Downloads folder.
When you post your response, click the "camera" icon above the text field:
This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button.
⌘ Shift 4 and then pressing the space bar captures the frontmost window.
⌘ Shift 3 captures the entire screen.
Drag the screenshot to the Trash after you post your reply.

Hold down the alt key immediately after power-up, select which OS you want to boot, holding ctrl when you select an OS makes it the default.

I have a white screen with an apple and nothing will work?

Turned my mac on and have a plain screen with an apple logo. Nothing will work?

Hi,
Some kernel extension or driver isn't loading properly, it seems. Try booting in Safe Mode by holding the Shift key down on startup until you reach the grey Apple backdrop with the spinning cogwheel and a progress bar. As soon as the progress bar shows up, you can let go of the Shift key.
Booting in Safe Mode takes a lo-ooong time, so be patient and don't interrupt (the computer booting, not me talking...). Once you've reached a workable Desktop, reboot in normal mode and tell us if it solved your problem.

Installer stopped at 95% and won't let me force quit, restart or turn off the computer

The flash player install manager stopped at 95% on my Mac and has been like that for a couple of days now. I can't end the installer, I can't even force quit. The installer doesn't allow me to restart or turn off the computer, because it's "still installing".
How can I solve this problem? Please help me!

Hello,
Did you tried Flash Player 11.2, Flash Player Archived : http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
Use Flash Player uinstaller (http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html) to clean any instance for Flash Player.
