Stuck on White Screen on Thunderbolt Display Update - Lion

Anyone else have this problem? After the Thunderbolt display update, I get a white screen at the login after I restart my MacBook Pro. I either have to unplug my laptop so I can see the screen again to login, or I can hit enter and then blindly put in my password while he screen is blank and then it will pop back up again. It's annoying.
I didn't have this problem running Snow Leopard and I reset the PRAM and SMC already. This is also a clean install of Lion.

I've actually just posted a similar post on the Thunderbolt thread. Is there anyway to rollback the firmware? This is so frutrating to have to wait so long before actually getting to the login screen.
If the Thunderbold display is unplugged then the MacBook has no problems and instantly goes into the login screen - on the other hand having the Thunderbolt display connected to the MacBook - same as you describe - Power on Macbook - white screen for about 1-3 minutes before the Apple logo appears and proceeds to the login screen
Hope someone can read and sort thins out soon.

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.

i can not get in to my os system. the screen just stuck in white screen and apple logo

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into 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.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

I am sorry i wrote post with same problem like https://discussions.apple.com/thread/6759865

..and solved. The secret seemed to be to follow these steps. Have no idea if they are all necessary but it worked for me.
In Display preferences hit gather window to bring the thunderbolt display preferences onto the mac screen
Uncheck Adjust brightness automatically and save
disconnect the display from the mac.
Restart the mac
Power down the display and leave for a few minutes
Power up the display
Reconnect the display to the mac
The screen returned to life. Let's see if it stays that way, I will report if it doesn't.

Thunderbolt display update 1.2 causes unresponsive display

After running the thunderbolt display update 1.2 my display now displays the very thing the update was designed was supposed to correct - a black unresponsive screen (which I have ironically never suffered fro at all ever - grrrr).
I cannot get the thunderbolt display to come back to life although the mac can see it and thinks it is there and is extending the desktop to it.
Anyone else have this issue or ideas to solve?

Apple Hardware Test Stuck with white screen

hy every one..............
i am unable to start the apple hardware test ,i've done anything ,holding d at start up with inserted installation disk,also with holding c........
also inserted application cd....
apple logo appear and after some time with spinning wheel it stuck with white screen....What that means
please help me out....
what can i do???

If you are still using Snow Leopard -
Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Snow Leopard - This will install a "fresh" copy of Snow Leopard without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.

HI,
*"I have opened disk utility top repair disk, but when I click on disc image, repair / verify disk buttons are unavailable to click and S.M.A.R.T status is not supported."*
You need to select "MacintoshHD 10.5.8 not "disc image" in order to run Disk Utility and Verify and if necessary, Repair the disk.
That's why you are seeing this dialog.
*are unavailable to click and S.M.A.R.T status is not supported.*
Also, run the Apple Hardware Test.

HT201263 iPod touch 4th gen stuck on apple screen after trying to update ios 6

iPod 4th gen stuck on apple screen after I tried updating to IOS 6. It won't turn off or reset even after updating iTunes to latest version. My iPod doesn't show up when I connect to iTunes. HELP PLEASE!

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iPod 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.

IPod touch 2G stuck on white screen

I can't get it to go back to the home screen. It has a white screen on the display, but the home button does not work. When I push the on/off button with the home button, it makes the sound of a camera shutter taking a photo. How do I get my Touch out of this mode??? Thanks in advance...

Tricky. Thanks for the assist. I ended up resetting to factory standards from iTunes and reinstalling all music and apps. Took a bit longer than pressing and holding I bet....

HT6093 Thunderbolt Display Update fail

I continue to get notices of a Thunderbolt Display update but it fails each time before loading. What should I do?

Same.
I have three thunderbolt displays connected to a Mac Pro. I got the error message, then read that no more than two displays could be connected during the update. I disconnected one of them and restarted. Then connected the other and disconnected the first and restarted again.
I'm not sure any of that worked and have no "active" notification that they were updated. I checked the firmware version following that update per the instructions and they match the version, but I'm still getting the random flicker.

I tried many times to turn it on, it turns and the same white screen appears and the update starts again and shuts down. Please Help me!

Hello!
I have a MacBook Air. I have got a software update notification couple of days ago. I've clicked on it today, and it started installing updates.
But, I have got a notification telling that not all updates were installed successfully, then I have clicked on "Restart" from the notification box. Then my Mac restarted and the white screen with Apple logo and the update progress appeared (like what always happens during updates).
The problem that while the update progress reached around half the way, my Mac shutdown. I tried many times to turn it on, it turns and the same white screen appears and the update starts again and shuts down.
Please Help me!
MacBook Air (11-inch Mid 2009)

Welcome to Apple Discussions
You did not state whether you installed the update while on battery (not mains) power. You are warned not to apply certain updates without being connected to a charger & mains power.
Also remove any attached peripherals.
Reboot in Repair mode (command-R at start) and use Disk Tools-Disk Utility-Disk First AId to repair your disk, and as long as you're there repair permissions. Next quit Disk Tools and reinstall the OS. After completing that successfully reboot, log in and do a combo update.
You must have more than enough (not just enough) empty (free) disk space for the update.

Mac stuck on white screen after booting.

My Mac boots and after the spinning wheel at apple logo vanishes it gets stuck on white screen..
I was running the following commands in terminal when my mac froze and I had to restart it.. After that it is on the white screen..
The commands I ran :
cd Applications
cd XAMPP/xamppfiles/htdocs/experiment
ls -l
sudo chmod 0644 /
And after that my Mac froze and I had to force restart by holding the power button.. After restart its stuck on white screen just before the login screen.

I am able to boot in Recovery HD.. did the repair permissions but that sudo command had affected the entire drive.. Reinstalling was the only option left..
Although I had to do
sudo chmod 0644 /Applications/XAMPP/xamppfiles/htdocs
but ended up pressing the return key just after the first "/"
Thanks for your help.
