White Screen after recent update

I was updating my ipod in the locked mode when the ipod screen, still connected to the computer, went to the "apple" screen, then white. I've tried to reset my ipod by toggling the lock button (hold button) back and forth, then pushing the center button and the menu key to reset. I get three chimes, then the screen turns immediately white again and bypasses the "apple" screen.
I have Mac OS X 10.3.9. I own an older version of the iMac.

Welcome to Apple Discussions!
You need to first put the iPod in Disk Mode...

Mac stuck on white screen after software update

I updated to snow leopard and then then to 10.6.8. After the updates had installed, my computer restarted and now it's stuck on a white screen. No key shortcuts work at all, I've tried. None of them work. Every time I try to turn it on it's just frozen on a blank white screen. Twice it's gone to the apple logo and been able to start up after 20 or so minutes of being on the white screen but each time it froze. I don't know what to do.

There have been problems with the Apple servers not linking to support articles, so some links may not load the first time.

IMac has white screen after last update!

I am running maverick on my iMac. After this last update installed I am getting the white screen. It was working fine before. I have tried unplugging everything and restarting and that did not work. I have downloaded and reinstalled maverick and that didn't work. I have ran the disk utilities and the disk and permissions are good. When I am in the disk utility screen there are fuzzy about 1 inch lines running up and down the screen about 2 inches apart. And when I enter the disk utility start up the screen that is gray with the apple logo is all fuzzy. I have a time machine backup but it is a month or so old and I have a couple of files I really need to save if I can.

I Have gotten in using the left shift key forcing safe mode. There are still verticle lines up and down the screen.

Lots of crashing, freezing, and strange lines on screen after recent update

I dutifully update the software when asked and suddenly I have all the following symptoms. Any advice? Thanks!
AD
1. A small line appears in some windows; it's multi-colored and about 3 pixels high. It goes away when I resize or play with the window.
2. My computer crashes more often when being woken up from sleeping by pressing the mouse button; I will press my mouse to wake up the computer and it just shuts off. This has happened for the past year but happens much more frequently this week after the recent update. I took it in to the apple store months ago and they could not repeat it. It happened 3x today.
3. A few programs have frozen / stopped responding, way too more frequently than normal.
Thanks!

Hi again Andy, I don't make it over here to Leo very often.
Here's what I'd try...
Safe Boot, (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
Leo clears a lot more caches than Tiger does in Safe boot.

White screen after system update

imac white cover, purchased 2005, Snow Lepoard oprating Sysytem
imac System was operating with out any problems
It had been a while since I had updated the imac. I updated system with system update and resatrted as instructed. The script to finish installing the updates stopped and stalled out for over an hour.
Turned off the system and I got a white screen. I have tried several restarts and it still gives me white screen
If you have a solution to try or do I need to bring computer in the Genius bar
Thank you

Try a 'Safe Boot': restart holding down the Shift key until you see a grey progress bar. Once booted restart as normal from the Apple menu.
If that doesn't help try booting using the grey restore disk that came with the Mac and running Disk Utility to verify/repair the hard disk.
A few other suggestions here if you still have problems: http://support.apple.com/kb/TS2570

Sudden blank monitor screen after recent update ... Why?

I'm the lucky owner of two ATV2s ... I use one on our regular Sony TV. I works just fine. The other one has been hooked up in an uncommon setup with a 24" cheap Samsung PC monitor. I then use AirPlay to stream audio to a good AirPlay speaker. It has been working so sweet until today when I decided to update the ATV software.
After the update the ATV refused to forward a signal to my monitor. Is there a particular reason why this happen? Should we expect a major move from Apple on TV's or are we not supposed to use Samsung gear in conjunction with Apple gear ;-)
Kind Regards,
Christian

Need a guru to help me out please.

Thin white line acroos the top of my screen after software update. Can NPRAM reset help to solve this or is it a permanent pixel problem?

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.

HT3775 Quicktime no longer plays wmv files after recent update

after recent update, quicktime will not open wmv files. had no problem opening them up in the past. reinstalled flip4mac codec and nothing. don't want to use quicklime player 7 b/c need to use fast forward option that will not work with QT7. Any help is appreciated.
thank you,
Damian

I ended up on the phone with an Apple iPhoto expert after scheduling an appointment online (go to Apple support). He spent an hour or so diagnosing my particular problem and was able to fix it. I can once again view all my mov files in iPhoto. Since every computer is different, you might want to try that route. He was able to view my computer screen and direct me to do different things.

[Solved] White screen after KDE 4.11.1 upgrade

Hi!
I updated the system going from KDE 4.11.0 to KDE 4.11.1. On reboot I got the correct loading of KDM, but upon arrival on the desktop the latter is presented fully white with big red button with an "X" in them. Thinking it was the configuration of kde, I deleted .kde4 with the effect that the next time I always white screen (that is only the red buttons have disappeared).
I try to remove completely kde with:
pacman -Rsnc kde
and seeing that reinstalling I get the same result, I also tried to clean up the cache pacman packages listed by the command:
ls kde*4.11.1*
so I redownload and reinstalled with:
pacman -Syu kde
without solution. I also tried to do what is recommended in the wiki, that is in addition to eliminating .kde4, I run:
$ rm ~/.config/Trolltech.conf
$ kbuildsycoca4 --noincremental
without solution.
Thinking then it might be the partition / almost full, I checked with:
df
but the partition is not filled even for half of the 30gb that is available.
I checked some logs and these are the outputs:

Thanks Thaodan! I deleted /var/tmp/kdecache-$USER and I solve the problem! I also restore .kde4_backup and at the moment have no issue.
Small question: I noticed that there are also kdecache-kdm and kdecache-root. I should remove it or doesn't matter?
Thanks for the help!
THANKS, my White Screen was caused by a combination of issues but this solution worked for me.
My Problem -
I am not sure exactly what caused my white screen, I was playing around with /etc/profile & /etc/sudoers
What I changed -
sudoers - I added my user group to sudoers and allowed sudo to execute applications using xauth in home dir
profile - changed umask to 133 ( I hate execute bit ) and default text editor to nano
What Happened -
Tried to reload via source but no changes where taking effect so I rebooted.
Upon reboot I could not login to KDE, it would keep looping back to the KDM after I entered by password for my user, however it would let me login as root ( after I enabled root login ).
I figured this was a permission issue so I changed umask back to 022 in /etc/profile, I was then greeted with the White Screen after login. I read numerous posts about how to fix this, most said to reinstall kde and delete /tmp, none of this worked.
I deleted /var/tmp/kdecache-$USER and now I am back in business ( I had to re set the widgets, i.e. panel ).
I was so excited that I had to write a post about it!
Thanks again!

My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!

My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

I expect that you mean some version of iPad.
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.
