IMac goes to blank white screen while using have to unplug

For the second time now my iMac 2.8 ghz Core 2 Duo has gone to a blank white screen right in the middle of doing work. The machine sounds the same but the only way to get it back is to unplug it. I've searched around and found booting issues but that is not my problem. It just goes blank white right in the middle of using it.

What "restore icon"?
If you have the Mac OS X install disc in the drive, switch on your Mac, and hold the Option (⌥) key.
You will see a grey screen, with Macintosh HD & after a few seconds, a CD with Mac OS X Install DVD.
Click on the DVD and then the arrow underneath it. This will start up the Mac OS X installer.
From here, you need to choose your language and then from the Utilities menu, choose Disk Utility.
Then choose Macintosh HD from the left, and choose "Verify Disk" not permissions

I am trying to get into my Game Center app but every time I tap on the app it opens too a blank white screen. I have tried several times to reset my phone but I get the same result.

Hello there Sweebs44,
It sounds like you are tapping the Game Center app to open it, but the screen is blank. I recommend signing out of your account:
Go to Settings > Game Center, where you can:
Sign out (tap your Apple ID)
From: iPhone User Guide
http://help.apple.com/iphone/7/#/iph6c493cac
Then close all the running apps:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that restart the phone sign back into your account and try again:

HT1758 Can i connect my non apple laptop to my iMac and use the iMac as an extra/dual screen while using my laptop?

Got a new laptop from work, no choice on the type, but want to plug it's docking station into my iMac so I can use dual screens while using the laptop. Can I use the Ethernet port for this?

Welcome to Apple Support Communities
Target Display mode only supports Late 2009 and Mid 2010 27-inch iMacs, and Mid 2011 and newer iMacs to use them as external displays, but it only works over Mini DisplayPort or Thunderbolt, not Ethernet.
Your PC needs Mini DisplayPort or Thunderbolt (depending on your iMac) to be able to use your iMac as an external display, so it is probably that you cannot use the iMac as an external display. Instead, look for information in the Internet about VNC viewers that allow you to do that

My iMac goes to the white screen and stops

My mac was acting really poorly, I thought for sure I had a virus or spy ware and I inserted my reinstall disk and double clicked the restore icon. My screen gave me a question to restart and reinstall the OS X system. I clicked the OK button. The computer restarted came up to the white screen and now is frozen there. I have tried restarting several times with the same result. Is my mac now toast or what.

My ipod has a blank white screen. I have tried pressing home and power button at same time and a restore and its still the same. Can anyone help please

Can anyone help me please? My ipod has a white screen that i cant get rid off. I have tried pressing home and power button at same time. I have tried a restore from itunes and its still the same. I cant even turn it off. Please someone help me.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HT201210 why is my phone not turning on or anything it is sitting on a blank white screen and i have restored it and it is still doing the samething

i was on my phone on facebook and then my phone went all black and wouldnt let me turn it back on, and then i plugged it into the laptop and it told me i had to restore and i did , now my phone is staying as a white screen and wont let me do anything on it, why is this?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the issue continues, take the device to Apple for evaluation and possible replacement.

After installing Yosemite my Imac just goes to a white screen and freezes, it has been there for almost 36 hours any ideas as to why it is taking so long?

I have downloaded Yosemite from the App store and I attempted to upgrade from OS X 10.9.5. It is stuck on a white screen with a moveable mouse pointer but that is it. I can't get Command + L to work, so I can see any progress that is being made and I have tried to force boot it twice. Each time I force boot the machine I get a progress bar that goes about half way across and then just a blank white screen. I have read on some blogs that patience is the best procedure for this freeze but I have been waiting for almost 36 hours now and nothing is happening. One thing I want to mention is I have VMWare installed with a virtual machine of 300gigs, could this be the cause of the hangup? My 27inch IMAC is about 3 or 4 years old with a terabyte hard drive and 32gigs of ram. I have unplugged everything from the back except the network cable. Is about 36 hours reasonable for an upgrade? Is there a way to cut my losses and revert back to OS X 10.9.5?

When you start your notebook press F8 to enter Advanced boot options.
Is Repair my computer option available?
If yes choose it and press ENTER. Follow the menu on the screen and when you will see System recovery options try to use System Restore option.
Do you have some important data saved on your notebook?
If not install OS again using HDD recovery option and after 2 hours you will have clean preinstalled OS and everything will be OK again.

Store status bar shows that it is connecting, but only blank white screen

My iTunes library is fine, but when I was trying to add new music from Store, will NOT connect. The status bar on top shows it is connecting, and I even got just a "flash" of the store on my screen, but then just goes to blank white screen, no error message at all.
Very frustrating!

I have the same problem and have been fighting with it for several days. I think the last thing that I did before this happened was to let Quicktime update itself. When I open itunes and click on store, the connecting bar gets halfway and then stops. That leaves me with the white store page, if I leave it alone for a bit, I see words as in names of singers and but no pictures.
I have ran the diagnostics and see no problems at all, no event logs in windows, no errors at all. I've un-installed itunes and re-installed but no change. I'm using Norton 360 from comcast. I have windows 7 pro 64 bit. Also, the help in itunes doesn't display.
I put in a ticket with apple and the response I got back basically told me to do what I've already done. I created a new user and have the same issue.
Any help at all will be very much appreciated. I think this started August. 8, 2011.
thanks so much for reading

Ipod touch has blank white screen

My Ipod touch has a blank white screen. I have attempted to restore and restart. I have also reset. The touch is recognized on my itunes page. It will allow me to eject the ipod. I also put earphones on to determine whether I could hear anything (desperation). I can hear something through the speakers. Not music but kind of like dead air---a little hissing----so I know something is going on. I am confused about what to do or whether that little white screen is the beginning of the end. Any insight into my problem would be much appreciated

That symptom is covered here:

I can't connect to game centre - suddenly just a blank white screen?

Please help - I've had my ipad for a few years and never an issue - all of a sudden yesterday Game Center won't open - none of my games connect so I logged directly on to the Game Center app icon and it just brings up a blank white screen. I have logged out of my apple account and logged back in again, I have switched the ipad off completely and then switched on again, I have checked that wifi is connected and I have gone into settings to open the game centre settings and again it just hangs - it has my Apple ID at the top and then a blank screen underneath. I'm at a loss what to try next ... Any ideas welcome!! Thank you.

reset all settings
settings-general-reset-reset all settings
now reconnect to wifi
settings- wifi- click network name- enter password - join
if issue persists back up and restore as new via iTunes
Peace, Clyde

Upgraded MacBook Pro to OS X Yosemite, now all I see is a blank white screen?

After more then five hours of installation, all I'm left with is a blank white screen, does anyone have any suggestions? This is supposed to be seemles, I trust apple upgrades, was I wrong to be so trusting?

Hi Daniel,
Welcome to Apple Support Communities.
It sounds like your MacBook Pro isn’t starting up normally since upgrading to OS X Yosemite. The article linked below provides a lot of information and troubleshooting suggestions that will resolve most issues like the one that you’ve described.

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.

I don't know if you've already resolved your problem, but I had the same thing, it took me 6 hours to fix it. I had the exact same as you, installed the update and then it went to a white screen. After trying start up holding down cmmd r or holding down the alt key to try to install it again, nothing worked, same result every time. Then an angel came to me here somewhere but I can't find it now to thank him. Start in safe mode, press shift once you hear the start up chime and hold it down until you hear it again. Installation completion box came up and it was working. turn off computer and start up again normally and all is well. Except my final cut pro x doesn't work with it, have to update that now too. same as when I updated to mavericks.
Hope this helps.

Hello KCC4ME,
You may try booting your Mac in Safe Boot, as it can resolve many issues that may prevent a successful login.
OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/HT1564
If a Safe Boot allows you to successfully log in, you may have issues with one or more login itmes (while the following article is labelled as a Mavericks article, it is viable for earlier versions of the Mac OS, as well).
