White Screen and Shadows

When I have a totally white window on my 30" cinema display and I move it across the desktop, I tend to notice some light shadows that quickly disappear. Do others have this with there monitor? I noticed it happens on my Dell flat screen at work as well. However, some monitors seem worse than others. Is this something that is considered a problem? Or is it normal?

This is the liquid crystal response time. It is normal. There is a molecule that has to twist and untwist in response to appled voltage in order to shutter the backlight to create different perceived levels of color and brightness. The twisting action has a finite speed measured in milliseconds. This is what you are seeing. Your eye is faster than the response time of the LC twist. You are right that some displays are better than others in this regard. Also normal and to be expected.

Help! When I select "Phone" it tries to open and gives me a white screen and closes. I cannot view my missed calls or voicemails.

If anyone knows anything about this...
When I select "Phone" on my home screen the iPhone attempts to open it, brings up a white screen and then will shut back down. I have 8 missed calls or voicemails yesterday and I couldn't check any of them. Does this happen to anyone else?
Also, when I receive a call and I answer it does not give me the ability to end call or any of my options (sources, keypad,etc.) during the call.
Basically, I can't do anything with my contacts, favorites, missed calls or voicemails.
Can someone please help?

I have tried that multiple times. I have also made sure that I have the latest updates. Would haveing 27,000+ contacts have anything to do with it?
Sometimes it works and sometimes it doesn't

This is my first mac, it is a macbook pro. i restarted it but when it started back up i saw a white screen and then it prompted me to insert the reboot disk. anyone else have this problem?

I recently bought a Macbook Pro, this is my first Mac. I restarted it, but when it started back there was a plain white screen and then it prompted me to insert the reboot disk. Has anyone else had this problem and is there a way to do this manually like with PC's?

The new Mac's came with OS X Lion 10.7 and there are no boot disks.
Since it's so new, take it back to the Apple Store and let them deal with it.
If not you can hold Command and r (as in rotten) keys down and boot the computer.
You'll be presented with a several options, including one to reinstall OS X Lion provided you have a Apple ID, which means you have to use Safari in there to set one up. To do that you need to set up a email account with Google or Yahoo. Once you get the ID, then you can download Lion and reinstall it.
It's so stupid not having a copy of the OS on hand to perform your own repairs.
Of course Apple will be happy to sell you a $69 Lion USB stick.
Like I said, take it back to the store, and try to get your money back, that will force them to think about just giving you a replacement machine that works.
Lion doesn't work really but it can be acceptable until the patches get released.

My Macbook Pro is frozen on the login page with a white screen and only my login picture. How do I fix this? I can't turn it off and I closed it and let it charge but it's still not working.

My Macbook Pro is frozen on the login page with a white screen and only my login picture. How do I fix this? I can't turn it off and I closed it and let it charge but it's still not working. It's only 3 months old and was working perfectly fine 30min before this happened.

Hello Kierasully,
I would start your troubleshooting with the article below for issues of not being able to log in to your Mac. Start with booting up in to Safe Boot as well as resetting PRAM on your Mac. If that does not work, then verify the hard drive with booting to the Recover HD and go to Disk Utility to verify it.

This can also be a problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
You will have to redo App Tabs and Tab Groups after deleting sessionstore.js.

My new Mac mini (3 month) didn't start up, all that appeared was a white screen and a flashing folder with a question mark inside it.
I followed by recommendations from 'Everything Mac': "shut it down by pressing and holding the power button for about 5 seconds.
Then hold down the Option key and press the power button again to start up the Mac mini. Keep holding down the Option key until
the Mac mini starts up."
But I got a Wi-Fi button only to chose and connect the local network. I connected to my network and I can't use this connection
becouse no icons.
Could you please help me?

Your Mini (running 10.6.4) should have come with grey-colored install disks. Now is the time to put them into service. Turn on your computer so that there is power to accept disk #1 into the optical drive. Once the disk is in the drive, shut off the computer by holding the start button down until it powers off. Then turn it on this time holding down the "C" key to make the computer boot from the disk. The question mark that you saw indicates that the computer cannot find a bootable volume. This can happen due to corrupted system files or an improper shutdown etc. Once you are in the "Installer" you can choose Disk Utility from the Utilities Menu in the menu bar. Use it to repair the disk and to see if that can solve your trouble.

21" iMac getting white screen and does not boot up

Hi All!
This is my first time to post here but have been using Mac OS since 2009.
I am having issues with my Mid 2011 iMac 21". I keep getting a white screen and it does not boot up.
I am a bit technical so I have done all the necessary steps as below:
1. Powercycle the system (Shutdown, unplug for 10 seconds and replug) = No go
2. Reset NVRAM several times = No go
3. Went to Safe Boot = Vertical white stripes on blue screen appears
4. Tried booting on Recovery Disk = Vertical white stripes on blue screen appears
I'm thinking my video card is faulty now.
Any help guys? I hope my hard drive is not fried
What's worse, my 3 year extended warranty just expired last June and it's only been 3 months

First i can't send it back becuase it didnt have a warranty i purchased it on ebay. second the guy didnt send the install disks with it as he promised i have tried to follow up with him with no luck so hes been reported to ebay. and due to current buisiness expenses cant afford the new software. is there anything else i can do to at least boot the thing so i can figure out whats wrong with it. and has anybody experienced this before and if so how was the issue resolved. soooo frustrated as buisiness is at a stand still till this machine works. p.s.it has osx leopard latest version.

Recently when clicking on Safari, it refused to open saying there were some components damaged. It was suggested I backup, remove OSX and reinstall. Now all I get is white screen and apple logo when starting. What to do?l

I Have an iMac desktop purchased in 2010 with OS X 6.1.6 and Snow Leapard. Recently after starting up, I was not able to open Safari. I checked for updates and all was well. I tried again and got a message saying Safari could not be opened because some components were damaged. After using Disk utilities to try and repair, it was suggested I uninstall OS X and reinstall from the disk. I did not at the time because I wanted to backup some info to a USB drive. But now when I startup all I get is the white screen and Apple logo and the loading symbol. What happened and How can Imfix it? I am not very tech savvy and don't know where to turn!

Hi nancy mfromamity harbor,
Welcome to the Support Communities! It sounds like reinstalling the Snow Leopard operating system is your next step. This should not affect the documents and data that you currently have on your iMac. I'll include the information to show you how below.
Mac OS X 10.6: Reinstalling Mac OS X
http://support.apple.com/kb/PH6606
Under some circumstances, you may need to reinstall Mac OS X. You can reinstall Mac OS X while keeping your files and user settings intact.
Note:To reinstall Mac OS X from another computer on your network, see:
Using another computer’s DVD or CD drive
To reinstall Mac OS X:
Insert the Mac OS X installation disc and double-click the Install Mac OS X icon.
Follow the onscreen instructions. In the pane where you select a disk, select your current Mac OS X disk (in most cases, it will be the only one available).
If you want to control which parts of Mac OS X are installed, click Customize, and then select the parts you want to install.
To start the installation, click Install.
If you purchased a standalone version of Mac OS X, these installation instructions are in a PDF file located on the Mac OS X installation disc.
If you need to reinstall the version of Mac OS X that was on your computer when you purchased it, or if you need to restore all the software on your computer (including Apple software, third-party applications, and other printer drivers), refer to the documentation that came with your computer.
If you need to reinstall Mac OS X and you’ve been using Time Machine to back up your applications, files, and user settings, you can easily restore this information from your Time Machine backup disk after you’ve reinstalled Mac OS X.

My IPad Air is frozen with a white screen and Apple Logo on it.

My Ipad Air is frozen with the white screen and apple logo. I've tried resetting it several times and that doesn't help. I tried connecting to ITunes, but it isn't recognizing the device.
The battery is fully charged, at least for now, so I am not sure what else to try.

FORCE IPAD INTO RECOVERY MODE
1. Turn off iPad
2. Turn on computer and launch iTunes (make sure you have the latest version of iTune)
3. Plug USB cable into computer's USB port
4. Hold Home button down and plug the other end of cable into docking port.
DO NOT RELEASE BUTTON until you see picture of iTunes and plug
5. Release Home button.
ON COMPUTER
6. iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes.
7. Select "Restore iPad"...
Note:
1. Data will be lost if you do not have backup
2. You must follow step 1 to step 4 VERY CLOSELY.
3. Repeat the process if necessary.

Not used my G5 Powermac (late 2004) for ages. Only boots in with Installation disk, but colour dots on white screen and message comes up to reboot machine. Nothing happens.

Not used my G5 Powermac (late 2004) for about 2 years. Was going to set it up for the lads to do school work.
However it only boots in with Installation disk, but colour dots on white screen and message comes up to reboot machine. However nothing happens apart from me keep trying. Also the numerous fans get louder and louder and louder.....
Any ideas folks

Can you please provide details on the exact model?
For a start, the PRAM battery is likely dead. PRAM tells the computer which drive to start with, other basic information. Still, you can usually get the computer to start, though bad PRAM is unpredictable and could be stopping that.
Some computer models use software to control cooling fans. If there's no software commands they automatically go into high speed to prevent overheating. Your software obviously isn't loading, so runaway fans.
