This symbol means you need to connect your phone to your computer's iTunes via the USB cable and restore the phone.

Brand new MacBookPro 13" , Stuck at White Screen with gray apple and spinning gear.

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.

White screen with gray Apple logo.

Could anybody help me? i bought my MacBook, about 3 months ago and never had any problems with it, 3 days ago i want to restart it after i tried to make an actuallitation... so when i did it just appears a white screen with gray apple logo, and no timer going... i look for help here in the apple discussions, and some guy seem to have the same problem... i did just what the other user recomended, i insert the original cd, while press the C key, and went to disk utilities on the bar on top, and clik on Repair Disk. When i did it appears a list of things that says:
Verify and Repair volumen “Macintosh HD”
Checkin Journaled HFS Plus volume
Checkin Extents Overflow file
Checkin Catalog file.
Checkin multi-linked files.
Checkin Catalog hierarchy
Checkin Extended Attributes file
Checkin volume bitmap
Checkin volume information
The volume Macintosh HD appears to be OK. (Font in green)
Then i didnt know what to do so i restarted and after that it appears the same White screen with gray Apple logo.
If somebody can help me, i will apreciate it, Thanks.

Your system info shows you are using OS 10.1. How is that possible if your Macbook is only 3 months old? You will need to correct the information if incorrect & insert the correct information.
After disconnecting all periperals try Resetting your Mac's PRAM and NVRAM. If that does not work try Apple Portables: Resetting the System Management Controller (SMC)
Since you are still under warranty, you can contact Apple about the problem if the solutions do not work.

Help! White screen with gray folder with question mark

Help, my macbook always shows this white screen with gray folder with question mark after turning it on.

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
With 10.4, 10.5 or 10.6 put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion or 10.8 Mountain Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 or 10.8 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

All I have on my I pod touch is a white screen with multicolored lines going across screen. What do I need to do. I can't use I tunes because it says I have to have passcode and can't get screen to come up. I have already tried holding both keys down.

- See if placing the iPod in Recovery mode will allow a restore.. It bypasses the passcode (and erases the iPod)
- Next try DFU mode

My 1st generation Ipod touch won't turn on at all and whenever I press the buttons to reset it all I get is a white screen, or a white screen with black lines across.

You can work through the five 5 R's of troubleshooting to rule out the possibility of corrupted software.

It might also be a good idea to let the iPod's battery fully drain. Then charge it back up and restore it once more in iTunes.
Otherwise, it's likely a hardware issue with the iPod's LCD display, meaning you'll need to take or send your iPod in for service either via Apple or a third party repair service. Here is Apple's repair pricing.
http://www.apple.com/support/ipod/service/prices/
Note that they don't actually repair the device, but exchange it for one of the same generation, model, and capacity. A third party service will actually replace the damaged part for a little less. Google "iPod screen repair" and you should get a number of results to work with.

Bescobar23,
which model MacBook do you have, and which version of OS X is installed on it?

Iphone 3gs shutdowns random, it fails to turn on, it displays a white screen with colors lines

I have an iPhone 3GS. It It shutdowns random, it fails to turn on, it displays a white screen with colors lines.

I have the 3GS and it recently started the RSD. At first I thought it was just the batter not holding a charge and being lower than what the display showed. However, even when fully charged the RSD's occur mostly when loading either Apps or web pages in Safari.
I have not experienced the white screen and colored line, yet apparently. Is this the logic board like in the MacBook's?

Boot with your install disc, launch Disk Utility, and repair the boot volume.

Mac OS 10.8.2 failed to update. Can only see white screen with spinning lines. Help?!

I have just updated my Macbook Pro (Mid 2010) to Mac OS X 10.8.2. My computer restarted and now it won't load back up again. All I see is a bright white screen with a spinning/flashing lines that you get when Safari loads a new page. I've left it on for 20 minutes and still the white screen remains. Does this mean I have to book an appointment with the Genius Bar?

Same problem. My Mac Pro 2008 stops booting at the white Apple screen. I reinstalled after booting into Revocery, and have the same problem. I'm going to try reinstalling an earlier version. Wish I coipuld bill Apple for the missed work today... And tomorrow if tha doesn't work.

White screen with vertical lines when opening.

My laptop has recently started showing a white screen with different colored vertical lines across it when opening the lid. It doesn't happen all the time but often enough to be concerning. If you close the lid and open again 95% of the time everything is good - with another try or two we can always get it back. There aren't any flickers or anything like that while using it. It sounds to me like a potential connection or short in the wiring. Am I on the right track? Thanks Donny

well i went to the apple store and went to the genius bar, they didn't tell me what caused my problem or what happened but they replaced my iphone! hopefully this doesn't happen again

HT201412 My I phone five isn't responding and when I turn it on, I get a white screen with black lines and I can't get into my phone. What is happening?

My iPhone five decided to go crazy and give me a white screen with black stripes and I can't get into my phone. I can only use Siri! What's happening?

You posted in the iPad forum instead of the iPhone forum. To get answers to your question, next time post in the proper forum. See https://discussions.apple.com/index.jspa I'll request that Apple relocate your post.

My iPhone 3G (8G) has the White screen with Grey lines, how do I fix it?

Hello!, am a new iphone user I bought an iPhone off my friend and put my sim card in the iPhone.
I've had my iPhone for 2 months nearly, when I got the iPhone it was in Great condition still is...BUT... I have the 'white screen of death' but with grey lines down the screen, I thought it was only tempory because when I smacked the phone against something it would work again, but now the problem is Permanant!!
I've been on youtube and typed in my problem and people have suggested:
- Holding the home screen and lock at the same time (it did nothing)
- Holding the home screen and lock and the up volume key (it did nothing)
- Restoring and updating the phone (it just came up with errors 4,9 and 21)
I really have no idea what to do, can I replace the whole screen? would that work?
or am I utterly screwed?
I really can't live with out having my iPhone! Help!

sounds like your LCD is broken. Replacing it would fix your problem. If you're handy with mechanical things you can replace it yourself, there are plenty of video's online who show you how. Order the parts and do it yourself, or you can pay roughly $50-75 to have it replaced.

I have a iPod touch 5th generation and when i turn on the device, its white screen with black lines and different colors

I can turn off the device naturally. But when i turn it on it shows all white with black lines and different colors. Is my LCD screen broken? If it is, can apple fix it?

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
Apple Retail Store - Genius Bar
If not covered by warranty
Apple will exchange your iPod for a refurbished one for $99 for 16 GB 5G and $149 for the other 5Gs. They do not fix yours.
