IMac white screen after sleep since latest update

Ever since I updated our iMac to 10.8.3, we get a blank white screen when we wake it from sleep. We can "wipe away" the white to reveal the desktop by dragging the mouse across the screen. It appears to be a video memory issue.

I have the same problem ever since I updated to 1.8.3.
Have any of you heard about a possible way to fix this?

27" 2009 iMac is stuck on white screen after OS X Maverick update

27" 2009 iMac is stuck on white screen after OS X Maverick update. How do I get past this White Screen? I have tried to use the PRAM reset, holding down Shift,Command, R, and P after turning off computer then when I turn it on, having those pressed until I see the apple symbol. I only hear one chime. Never get to a second chime. Thank you.

IPod frozen white screen after cancelled wifi system update

My iPod Touch 4g has a frozen white screen after cancelling wifi update to ios 5.1. My update bar was frozen middle way through when doing wifi update to ios 5.1. So i reset ipod and it displayed an apple logo which faded into a white screen. not jailbroken.

I let battery drain, plugged into computer but when it booted up it booted to an apple logo with lines across the screen. It is frozen. iTunes did not recognise, it never showed up on iTunes. It is fading into a white screen.

Help! Stuck on white screen after sleep mode and won't start again!

Bought the iMac last week, updated to 10.5.1. Worked well until this morning after I did a security update. Then put it in sleep mode - and basta! After I wanted to work on it again - it didn't restart. So, I had to switch off using power button, but it never started again and always got stuck on the white screen with the Apple logo and the rotating loop. Tried to repair permissions - cannot do it, as it says there is an error. Tried to re-install from DVD the Leopard while archiving the previous information - can't do either - says error. Now trying to re-install it again with an erase option. But this is not a good option, people! This is pretty very much disappointing, Apple!
Can anyone help, please!

Boy that is way too bad.
Could you tell us what the error message was?
While sometimes the error messages are not very informative, other times they are. That might be a clue as to what is going on.
When you restart from the DVD you have the option to access Apple's Disk Utility and repair the disk.
You might want to try that, skip repairing permissions at this point.
You can also reset the computer by unplugging all cables including the power cable for at least 15 seconds and then plug in the power cable and keyboard and restart.
You can reset the PRAM by holding down the command-option - p - r keys simultaneously during restart and waiting for the startup chime then releasing those keys after the second chime to allow the start to continue.

White screen after sleep using 10.8.3

Ever since I upgraded to 10.8.3 using the Combo update, whenever my computer wakes from sleep, I get an all-white screen. I can "select" parts of the screen using the mouse and the regular wallpaper comes into view. At that point I can use the computer just fine. I have re-installed the combo updtae and restarted the computer but the "white-outs" keep happeneing. Any thoughts as to why this is happening and what I can do to fix it? Thanks.

Try resetting the PRAM and SMC.
Restart the computer holding down the command - option/alt - P - R keys before the grey screen appears. Continue to hold until you hear the startup chime for the second time.
Reset NVRAM/PRAM
Try an SMC reset. The article covers when this is required, but doing this will not affect anything.
Reset SMC
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

Black screen after sleep Mavericks security update 2014-002

I get a black screen for about 10-20 seconds on waking from computer sleep/display sleep after installing security update 2014-002 for Mavericks. The computer is awake, because I can click and change windows, pointer/cursor placement, etc., from before the time the computer went to sleep. Never had this problem before this latest update.

If the resets don't help try the following in order as necessary:
1 - boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and repair both the disk and disk permissions. Reboot normally and check for improvements.
2 - boot into the Recovery volume (boot with the Command + R keys held down) and reinstall the system.

My ipod is stuck on a white screen after i tried to update IOS and turns on and off by itself :/

ok so last night im textin my sis with this app and i thought she was done texting me so i decided to update my ipod to IOS 6 and it took FOREVER just to download it idk why but anyways it said i needed a power source or a battery level over 50% so i just charged it with my wire nd wall charger. but the thing is about the wire is tht it teeds to have a problem charging it has to be in ceartain postions or shape for it to charge so when i plugged it in it had the charging icon at the top so i clicked install nd when i clicked install it said verifying update or something like that but after a couple seconds when i clicked it my sis sent me a text and i acciedently clicked lauched but eventually it shutdown to countine the update. so i waited for about 5 mins or less and i find that the little bar at the bottom froze so i shut the ipod off using the home and the power button. but then when i pressed then power button to turn it back on it showed me the apple logo then the screen dims just a little bit then the screen goes to a light blue and im like ***? so i shut if off again the same way i did the first but this time it turned on by itself and repeated the cycle untill i shut it off. so when ever i shut it off, i turns on BY ITSELF shows the logo for like 5 sec dims, then goes to a blue screen. but i tried repeating the cycle this one time nd at first it faded to white. then again i tried this time it when to blue then it changed to black very qucikly. but now i just left it on a white screen because it was the most common color of frozzen screens when i looked at gogle for answers. and now im soo ****** cuz i had just deleted alot of pics and some apps for the IOS 6 update -___-

but when u restore it doesnt that whipe everything out?
You may have to do the following
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.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

White screen after 10.6.7 update

I have just updated our 24" and 27" iMacs via software update. Immediately both suffer a white screen on startup.
In resolving the startup problem, I found removing usb cables on startup solves the problem temporarily, but consistently returns when cables are plugged back in and doing a cold boot.
On the 27" I have zapped PRAM, downloaded and reinstalled combo update (with usb cables removed), safebooted.
Any one else had this problem and solved? Any suggestions?

It's possible that the hardware you have connected to the usb cables need to be update to work with the update.
Try resetting the pram and smu.

IMac white screen after Lion system install

Two days ago, iMac froze with the dreaded white screen. Unplugged all external hardware. Restart with "Command R", fixed all permissions and verified the disk. Cold start locked at white screen. Reinstalled Lion. After the reinstall the system did restart on its own and everything looked normal. Shut down and did a cold restart and the white screen is back. Shut down and cold start with "Command R" very long process but Utilities finally opened. But what to do next?
This iMac has had the recalled Seagate hard drive replaced by Apple, although some years ago.
Thanks for your thoughts, Bill

Page 3,
After writing the above I went in and pressed the ON/OFF button, it went black and shut down. Waited 10 seconds and pressed the ON/OFF button and instantly my desktop and all folders were back. Everything looks normal.
Now each time I have verified permissions there has been a file that can not be fixed. A "SUID ..... " file. Have to do with anything?
I am going to shut her down one more time wait the 10 seconds and Start.... locked in white screen.
Restart with "Command R", and now it appears hung up on the Apple and spinner for a very long time and Utilities finally opened. Although it will take some time before it loads enough to make things selectable. When that happens I will do a Restart from the pull down Apple menu and see what happens.
Looks more and more like my Authorized Apple Store is about to get a visit.

IPod touch white screen after sleep?

After I put my iPod Touch to sleep, and I wake it up, I get a white screen that flickers from time to time, then just goes right back to sleep. I can sometimes coax it into coming up by sliding my finger over where the slid to unlock button would be, but that doesn't always work. I just bought it yesterday. Is this a widespread issue or should I just take it back?

Happens on my one aswell... but happens at any battery life level.
I don't know if it is me just me speculating or whatever but it seems to happen when i leave it for a few minutes on sleep... and so far it has only happened whilst listening to music.
Also, just for the record it is a week 38 model.
I might go into my local apple store on Saturday and see what i say, but sod's law says that when i try and show the genius it wont work.

HT6058 my ipad screen will not rotate since latest update

my ipad scrren will not rotate since latest update, i have done everything i can think of including wha tapple told me

What have you tried, and what did Apple tell you ?
Is there a lock symbol at the top of the screen next to the battery indicator ? If there is, then depending on what you've got Settings > General > Use Side Switch To set to (rotation lock or mute notifications), then you can lock/unlock the rotation by the switch on the right hand side of the iPad above the volume switch, or via control centre : swipe up from the bottom edge of the screen and it's the right-most of the 5 icons in the middle of it (if the icon is white then it's 'on', tap it to turn it grey and 'off'). The function that isn't on the side switch is set via control centre instead : http://support.apple.com/kb/HT4085
If there isn't a lock symbol then try a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

IMac will not boot. Stuck at white screen after chime.

I am starting a new thread this because it seems that other people with this problem are able to get their Macs working with some sort of keyboard combination on boot. I am not. Nothing is working. My computer is currently a 27 inch brick... Actually a lamp, since it is frozen on a really nice white screen.....
Installed Yosemite on my 27" iMac (early 2010, i7) when Yosemite came out a couple weeks ago. Everything was working fine but it wouldn't read my external drive, so I did a reboot. After the reboot, it freezes on the white screen after the chime. No keyboard combinations work to get it to do anything....also, if I hit the power button it shuts off immediately.
Nothing is working to get it moving. And yes, I am using a usb keyboard, not the Bluetooth, to try to hit any of the keyboard combinations posted in various discussions.
My AppleCare is expired, so I'm going to be very upset if I have to go pay to have Apple fix their problematic software. Any help you guys can give will be greatly appreciated.
Thank you,

See if you can boot into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

After installing the latest updates, my iMac will constantly crash and reboot.

After installing the latest updates for Mac OS X yesterday, my iMac constantly crashes and reboots. It will only boot properly in safe mode. Even when starting with command+R for recovery the kernel crashes. I have had this iMac for about 3 years and never had an issue until last night, when this problem started and it seems to have gotten worse over night. I already tried the <option><command><R><P>, but it seems that that made it worse as well.

Trying running this program and then copy and paste the output in a reply. Please use copy and paste as screen shots can be hard to read.

Have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!

have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!
The configure bar gets about an 1/8 full and then just does nothing. I think its lists the update as combo update? cant remember with out checking.
I have tried to do the disk verify and repair but this has made no difference.
Please let me know what i need to do, I have reformatted the mac just to start over as was clogged with a lot of useless data, I had installed lion (10.7) from the app store previously and now cant seem to find a way to re install lion. I hope I dont need to pay for it again?

If you erased your hard drive, you'll need to reinstll OS X 10.6 Snow Leopard to access the App store. You won't have to pay for OS X 10.7 Lion again. Did you try booting to the recovery partition by holding the command and r keys down? If that's still there, you can reinstall OS X 10.7 from there.
If you're looking to install the current iTunes, you need OS X 10.6.8 at a minimum.
If you're still trying to update OS X 10.5 Leopard, you can download the combo update from here. Download, use Disk Utility to repair permissions, apply the update, then repair permissions again. That will take you to OS X 10.5.8.
