OS X V10.7 Lion :: 10.7.4 Freezes On Login Screen?
Jun 29, 2012
I have a mid-2010 MacBook Pro and I've noticed several freezes on the login screen: it gets on the login screen and the multicolored spinning ball appears and you are not able to authenticate.. The only thing you can do is to force a shutdown with the power button. I always see this messages before the forced shutdown:
29/06/12 21:53:05,000 kernel NVDA(OpenGL): Channel exception! exception type = 0x6 = Fifo: Parse Error
29/06/12 21:53:05,000 kernel IOVendorGLContext::ReportGPURestart

Today my imac done something wierd. When powering on it got to the blue screen before the password login and it just froze on the blue screen. I done a hard restart and rebooted a few times. Didn't do it any more after that.
Should I be worried? It's only a few months old.

I just bought a LaCie 3TB external. When i turn my computer on and I'm at the login screen my trackpad and keyboard are frozen. When I unplug the LaCie (i know really bad) my mouse and keyboard start working again. Is the LaCie trying to work as my primary drive? Is that why it freezes my mouse and keyboard? How do I work around this (besides unplugging it from the computer)??

My iMac started freezing at the login screen. I power up, the apple logo comes up (sometimes the blinking globe comes up for some reason) and then the apple logo flashes as if it restarted or something, and the loading indicator shows up for a few seconds. Then at the login screen everything looks normal (my picture is there and correct name of account is shown) when I type the incorrect password, the text box shakes appropriately. When I type the correct password, the loading indicator appears, the mouse turns into a beach ball, and it hangs until I hard shutdown.
I know it's not a hardware issue because I just booted from the recovery partition and was able to view all my files in terminal. I would rather not reformat the hard drive. Is there a specific file that may be corrupted that I could delete and mavericks would automatically rebuild it?

I have a Mid-2007 Mac Mini and I've noticed every couple days, when I log out of the secondary account, it takes a relatively long time to return to the login screen. The blue screen sits there for maybe 30 - 40 seconds, but then when it returns to the main screen the whole machine freezes. The only thing I can move is the mouse, I can't click any of the buttons such as restart, sleep or get back into my account. I always have to do a hard shutdown.

I've been experiencing this for over a month now. Basically, occasionally when logging into a website (i.e. google, designers.mx, amazon, etc. -- really doesn't matter what site it seems), Lion will entirely freeze up for seconds to up to minutes. More specifically it occurs when tabbing from the username to the password field. This will happen both in Chrome and Firefox. I had thought it was related to maybe firefox add-ons (i.e. I have 1password, but i've disabled them and have had it still happen. I do use firebug, but wouldn't think it was related to this issue..I've already verified there are no issues in the keychain access as well.I can sometimes unfreeze momentarily it by pressing the power button briefly.

Notebooks affected by this troubleshoot:Macbook Pro 15" 6,2 Mid 2010 (OS 10.7.3) with all Apple updates installed - 2,66Ghz Core i7 - Apple SSD 128GBMacbook Pro 15" Late 2011 (OS 10.7.2) - 2,4Ghz Core i7 - standard specs Troubleshoot : At startup, Lion freezes before the user is able to type his login/password. We see the login prompt interface of Lion, but can't even move mouse cursor.Keyboard's inactive too because system is frozen.So you must force a shutdown.And it's a loop-freezes. You'll try several times to boot your laptop before it will succeed to open. (it's a 5-times boot to succeed - average) I've tried several times: P-Ram reset, repair the permissions of Macintosh HD with latest Lion recovery & from an external boot too.None of this has solved this issue. I'm sure I'm not the only one who saw that issue. Have to boot 5 or 10 times his Macbook Pro to succeed a boot is not a normal use

After waking up my computer from sleep I find that the screen saver always locks/freezes and becomes pixelated. I move my mouse around and it sort of "erases" the saver to reveal the login page underneath. This happens on my new iMac (2011) and now is starting to happen on my MacBook Air.

Installed Lion. Upgraded all 30,000 of my photos as per screen prompts. Now unable to use my Mac ANY time screen saver activates. It freezes, hangs, crashes. NEVER had any of these problems with 10.6 and, because I've "upgraded" my entire iPhoto Library (as per screen prompts) I am STUCK with this new OS!!
How can I "de-upgrade" my iPhoto library so I can revert to a system that functions?

From time to time, as I am composing a message using Gmail in Safari, the email screen "freezes." I cannot continue to type, copy or paste, or do anything else to manipulate the screen; it is as if the page has become an image. I speculate that this is due to some inadvertant "gesture" on my part, as at other times my Safari screen will sometimes zoom in and out unaccountably, presumably because my track pad senses two fingers pinching instead of scrolling. This latter problem is very annoying, but I attribute it to my own clumsiness. The former problem of the screen freeze is more than annoying, as it requires me to completely redo a sometimes lengthy email. Is there a gesture that causes a screen to be captured as an image?

I recently found out you can create custom login screen pictures and remove the apple logo and so on.A part I also loved was the login message. How to alter it so it could be made larger, text change and have new line capabilities (rather than having to space bar of to the end?)

It looks like the most recent revison to OS X, that being 10.7.4 moved, or otherwise changed the way the system displays the background image for the login screen. I use a custom image file for mine, and now that same file does not display in 10.7.4 The file (my coustom image) is still there, but it looks like OS X does not use that file anymore.This is the file name:[URL] how to customize the login screen background in the new build?

I have a Early 2008 Mac Pro running Lion. Its been running well but then last night it froze while I was on the internet. Pretty rare that this happens so I held the power off button and turned it off. Turned it back on and it made the chime noise, apple logo came up, a grey spinning wheel came up for about 30 seconds and then it stopped spinning and the computer froze there.
I tried a bunch of different things. I tried rebooting in safe mode, Recovery mode, From time machine external hard drive, Tried booting in the Windows partition that I have (its on the same as the boot drive I'm trying to boot in Lion off of).

when I tried to launch the macosx lion, after display the login window, the whole window become black.
Then I inject the U-Disk that has MacOSX Lion Installer in it, after the white screen, it become black too. So I can not re-install macosx.
Then I tried press `shift` at login. It also didn't solve the problem. At last I tried the single user mode. It appears some problems:
... USBF ... The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 4 of Hub at 0X24000000)
no interval found for . Using 8000000

A machine we have has 4-5 user accounts on it. The login screen GUI just has one user visible and I can't figure out how to log with my user ID and password. There aren't many places to click & I've tried pretty much every thing I can think of to log in as a different user. Am I missing anything obvious? Is there a chance that only certain accounts are enabled for logging in after a reboot?

I just noticed that my User Account Picture does not appear on my Login Screen in OS X 10.7.4 Lion. It never has and I just noticed on another Screen shot of someone else's login screen that their login picture is showing. I kind of like it. Can anyone tell me how to get it to display there? My computer was originally set to autologin when I first got it but I set it to require name and password.

my macbook pro today started to freeze at logo scrren. I tried to start it up in both safe and recovery modes but it doesn't work either. I got the system to start in safe mode only once and the scrren looked like in the attached image.When I tried printing the screen instead of taking a photo with my mobile, the image appeared to be normal (without those noisy rectangles), but it wasnt. Then itried restarting but it's been impossible. As i said i tried booting on safe and recovery modes but the circle below the apple logo appèars and then it freezes again. I read about aproblem with the graphic card similar to mine in earlier models, I don`t know if it is the same problem.

I just noticed that on my login screen, "Guest" appears even though it is disabled. I have not tried to run it, but when I do click on it I get the message that the computer will reboot into the "Guest" mode. I stopped at that point. This can't be normal.

Is there a way to disable or hide the sleep button at the login screen? I am trying to send updates and/or commands from ARD.... But the end users are putting the computers to sleep by pressing the sleep button. This is causing the ARD updates/commands to fail. The computers and severs are all Lion OSX. If I can disable the sleep button at login then I can send the updates/commands. I normally only do the updates/commands when there is no user logged in.So I am not concerned with the case where the user is already logged in and puts the computer to sleep. I have already setup an MCX in WGM for the Energy Saver.

I recently updated my MB to OSX Lion 10.7.4. I had to re-apply my custom menu bar and icons (as usual), but the first thing I noticed was that the login window was back to that disgusting linen texture.I thought the update just replaced the file, (didn't happen before), so I went to /System/Library/Frameworks/Appkit.framework/Versions/C/Resources/NsTexturedFull ScreenBackgroundColor.png. And then the file was the same, my previous login window.
So the question is: Where is the new login screen texture stored? I can change the mission control background, but no amount of goolging or anything provides accurate and working information to replace the login screen on 10.7.4.Why would Apple break this all of a sudden? The worse case scenario would be that Apple decided to troll and draw the login screen programmatically. Which should never be the case...

Hi! Im new to the forums but i really need help with something and i was hoping someone here could help me out. So I just installed Tech Tool Deluxe onto my macbook and then shut it down later. I went back to use it again and when i turned it on a login screen appeared asking me to put in my password. I did that and the screen turned blue (looking like it was loading) and then went back to the login screen. Every time i put in my password it just takes me back to the login screen. I have had my mac for a while and i dont want my hardrive to get wiped out so what do i do? Thank you for looking

I have a my iMac set to require login after it sits idle for a period of time. When I return and move the mouse or hit a button on the keyboard the login screen is simply black with the login field in the center. Q: Is there a way to change the color or set a background image for this screen? It is not the same screen that appears if I log out...the one with the gray linen with Apple logo. It is just plain black.

I just literally updated my macbook pro to the latest version of Lion, today 4/3/12 and now it's just stuck on the main log in page for lion. As in, I type in my password, it thinks for two seconds, goes black, and has the log in page again. It just loops. No end in site.I've rebooted in safe mode, run disk utitily, and repaired the disk... but no dice, still. It repairs the disk, fine right? When I reboot in regular mode, it just goes back to the password/login screen loop.

Apple writes in its OS X Lion screen sharing description that: "You can remotely log in to a Mac with any user account on that computer and control it, without interrupting someone else who might be using the computer under a different login."
Unfortunately, this is not true in my case: When other users are using my 2011 iMac for webbrowsing or DVD watching and I log in on my own acount from my macbook pro, video will stop playing, the spinning wheel sometime appears. The system does not really crash, but wil respond very slowly and in fact is not useable until I as remote user stop my activities or log out. This is not how it should be, especially as the iMac's CPU, memory and network load are very low according to activity monitor's information.

This is the first time I've encountered this. Upon cold booting the machine it went directly to the legacy Mac OS X Server login screen from before the upgrade to Mavericks. It would not let me login with current credentials. I had no choice but to hard power off. It returned to normal operation on restart.
It could be a possible bug.
