Login Screen Freezes

I have a Mac Pro currently running Mac OS X Server 10.4.10
Twice in the last week, when I have gone to log in as "Admin" the server freezes up right after I type in my password and click login...
We keep the server on all the time because our website is hosted on it, we just keep it logged out...
The only way I have figured out how to get out, is to hard reset the server sigh (which i did only once because it was absolutely necessary!)... Even thought the machine seems frozen, people can still access files and use mail service...
Any thoughts on why it might be freezing like this?

You do need to make sure your "server" is not set to sleep.
An Xserve won't (not under any normal circumstances), nor should any hardware you dedicate as a server.
As for the login issue, it could be an added login item or a bad preference for that (Admin) user account. It could even be a badly compromised item on that user account's Desktop.
You should enable ssh access as then you can (potentially) log in and safely restart or shutdown the unit.
Be sure
http://www.bombich.com/mactips/rsync.html - see "Before you start: Security Briefing" and the 2 sections that follow that.
Look into your logs for information about what was happening (or not) during the login hang. See ~/Library/Logs
as well as /var/log - both can be easily viewed via /Applications/Utilities/Console.app
While directly aimed at "10.3.9 and earlier" , judicious use of some info from the following article might help:
http://docs.info.apple.com/article.html?artnum=106464
First things I'd put aside (via ssh login) are:
/Library/Preferences/com.apple.loginwindow.plist
/Users/admin/Library/Preferences/com.apple.loginwindow.plist

[SOLVED] GNOME login screen freezes after 3 seconds

Hello,
today I installed Arch-Linux the first time. I had some issues during the installation (following https://wiki.archlinux.de/title/Anleitu … Einsteiger (its the german version, seems to differ a little from the english version)), but everything went good until I installed GNOME. Now the login screen freezes everytime after quite exactly 3 seconds, unless I press [strg]+[alt]+[f2] fast enough to switch in tty2. Then the screen will only freeze when I switch back to tty1. Once the screen is frozen, I can't switch to tty2 anymore.
I think the problem has something to do with my nvidia hybrid graphic system. During the installation I installed the packages bumblebee, bbswitch and primus, but uninstalled them because I thought they could be the problem. But although I uninstalled the packages, the "Stamina-Mode" status led is turned on after the system has started and the "Speed-Mode" status led not. I think that's a little bit strange, because I can't imagine which process is controlling these leds.
So I ran just
pacman -S xorg-drivers
and I had to create the xinitrc-file (because I could not find this file in /etc/skel). Now the default GUI appeared after I ran
startx
(I saw some windows and a clock). After that I installed gnome, changed the xinitrc-file in my userhome and got the freeze after a reboot.
I don't know if it has anything to do with my problem, but I get the following error-messages everytime I boot:
[drm:ibx_irq_handler] *ERROR* PCH transcoder A FIFO underrun
[drm:intel_dp_start_link_train] *ERROR* too many full retries, give up
[drm:ilk_display_irq_handler] *ERROR* Pipe A FIFO underrun
interl ips 0000:00:1f.6: thermal reporting for required devices not enabled, aborting
Hoeman
P.S.: Because I'm a total beginner at linux I probably missed the most important informations, but I can give you more if you tell me how

Ok, I could solve the problem myself by installing the latest nvidia driver. Now I guess the intel grahic card is not used anymore, but I don't really know...

After upgrading to yosemit login screen freeze upon waking up

After upgrade to Yosemite, my MacBook Air (1.3 GHz Intel Core i5, 8GB 1600 MHz DDR3, Intel HD Graphics 5000 1536 MB) sometimes freeze upon waking up, at login screen. With a white Apple logo on the top left corner of the screen, my login user name in the center, Cancel button at the bottom of the screen, and the usual login password text box is not available. I don't have control of the mouse or keyboard. This usually happens after extended sleep. The only way out of this situation is to hold down the power button to restart.
The only application I'm running at the time of sleep (closing the lid of my macbook air) is Parallel 9, with Windows 7 and Microsoft Outlook running inside the virtual machine. After rebooting the system, and relaunching Parallel, Windows 7 reports that it was shutdown unexpectedly.
Has any one run into this? Will upgrading Parallel 10 fix this problem?

I haven't found or seen a permanent solution. A temporary solution from another user is to change the screen resolution to the next lower. It solves the problem for now, at least for him. One other disbled their screen saver and increased the time period before sleep mode kicks in. Otherwise, the obvious is to disabled the sleep mode entirely for the time being. These are from people with different hardware. These may or may not help. If I run across a real fix I'll let you know. Appreciate, if you can do the same.

Problems with Login screen freeze and Bootcamp

Since installing Lion my MacbookPro very often freezes when i start it..When it reaches the login screen it just does nothing when i enter the Password......
In addition to that It takes a very long time when i try to boot under Windows....I press alt during the booting and before lion the partitions showed up very quickly...now it takes ages to do that....
Comeon Apple, fix this!

Meg,
I sent it to my exchange family in Chile. It was packaged so well, tons of bubble wrap, it couldn't have been damaged.
I worked for a professional camera company in Chicago. Our test for how well a sensitive camera part was packed was to take it to the 3rd floor and toss it out the window. Now that sounds rather radical but I've seen packages drop off the loading belt of a 747 straight down to the tarmac. The midline of that plane is about 31'. So once you see that happen our test was not so unreasonable.
I made sure the post office knew it was fragile, etc...
Well not to be cynical but those machines that do handling can be pretty uncaring.
I sent it to my exchange family in Chile.
I've tried to send a lot of cameras and parts to Uruguay. Only about half make it, the rest disappear.
They got the computer, plugged it in, and now they say the screen is acting all weird, turning different colors and freezing from time to time.
So that sounds like the BGA detachment problem. They could try the shim repair. It's easy to do on the G3 since the the GPU is on the bottom.
A reball is $79 here in the States plus shipping.
There's also the possibility that the chip itself has failed. The ATI Radeon Mobility 9200 had a known failure rate in Dells, Sonys, IBMs etc.
It the shim repair fixes the problem it can work for a long time.

Login Screen freezes after Lion 10.7.2 upgrade - needs 3 hard reboots

Just upgraded my 21.5" late 2009 iMac to OS X Lion 10.7.2.
0. Power up from cold start: login screen appears, and mouse works, but clicking on users does not bring up the password box. No option except for hard reboot.
1. Hold down power button until it shuts down. Power up, still no respponse (see 0.).
2. Hold down power button until it shuts down. Power up, still no respponse (see 0.).
3. Hold down power button until it shuts down. Power up, responds normally, can login (or start computing if login screen is bypassed).
I saw messages (mostly for MacBook Pros) dating back to July/August 2011 with similar problems. But none for 10.7.2, and none where it consistently takes 3 hard reboots to get a response. I tried all of the suggestions that applied: SMC reset, repair disk permissions, change password, bypass login screen. If I use automatic login, it boots up into my desktop and all the services seem to start. The mouse works, but nothing responds when I click on it (see 0.).
Any ideas?
thanks,
david

Thanks lynque. It turns out I did need a keychain repair, but that didn't fix the problem. I probably should have done this earlier, but I ended up unplugging all peripherals (2 firewire + 3 USB) then powered up without issue.
So I shut down, plugged in one at a time, and ran into the problem again after plugging in an external hard drive (WD My Book Essential). I repaired with disk utility, but the problem remained.
I then rebuilt the partitions with Disk Warrior, and now everything seems to work....

Login screen freezes after the Lion 10.7.1 update

After updating to 10.7.1 (the first Lion update) & restarting the system, it's not logging me in. As I give my password and press return it stays on the same login screen. I could move the mouse but there is no rotating wheel, just the same login screen. I tried starting Mac in safe mode but same thing.

Force a restart and at the chime hold down the SHIFT key. You will see a gray progress bar appear. When the login screen appears, reboot again WITHOUT holding down the SHIFT key. Then try logging in again.

After upgrading to Yosemite cannot load past login screen (FREEZE w/IMG)

I JUST updated to Yosemite, that went fine on my 2012 iMac. However I kept getting this MLB..... type plugin notification that would not go away. Even if i press more information or "ok" it would pop back up again every 10 seconds and kept it as an active window every time. I got very annoyed and started a purge of plugins and extensions that I read online that would relate to it.
So I guess somehow in my successful purge I deleted an essential start up extension/plugin. Because I can login successfully, but then when it attempts to load my account I get a freeze on this screen.
Yes I attempted to start in safe mode, it kept giving errors that start up failed to start properly
I attempted also disk repair. I repaired and verifyed disk through cmd + r and it said everything was fine. Rebooted, still got crazy start up screen
I also attempted D for a start up command, gave me an archaic verifying for hardware. Again it said nothing was wrong. I did the quick version, currently doing the more through version which takes up to 1+hrs and nothing so far.
I am asking can I put a start up disk, or some file on a USB start there and try to put back a correct set of start up files? All while trying to preserve my current files?
Thorough and general help is greatly appreciated!
Cheers,
Natalie

When my IMac awakes from sleep mode, the password login screen freezes and no cursor appears.

Hello! When my IMac awakens from sleep mode, my log in screen is frozen (I can't type anything) and there is no cursor.
I can turn the computer off and on again and then I have an active log in screen, but if I walk away from the computer and it goes into sleep mode and i have the same problem trying to bring it back from sleep mode.
Thoughts?

Hey Kristogirl,
I understand that when waking from sleep mode, your iMac freezes. Try executing these two troubleshooting steps:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
OS X Mountain Lion: Reset your computer’s PRAM
http://support.apple.com/kb/PH11243
If neither of those help the issue, I would follow the steps in the next article, specifically the "If the issue occurs in various applications, or in Mac OS X" section:

My Mac starts up fine in safe mode, but freezes before the login screen in normal mode.

I have the 2012 MBP, 4 GB of RAM, 500GB HD, 2.5GHz Intel i5 processor. Everything worked fine, until one day it freezes all of a sudden. I shut down and restarted. The Apple logo appears with the loading animation underneath. A few moments later, the animation disappears, and the mouse cursor appears. This is normal. What's not normal is that it stays on this screen forever. I can't get to the login screen even after waiting sooo long. Even restarting 5 times only repeats this problem. I finally boot into safe mode. I am able to login and get to the desktop in safe mode, but not normal mode. Clearing every startup item in System Prefs, and in the startupitems folders does not solve the problem. Disk utility says no problems. Resetting PRAM does nothing. Can anyone please tell me what I should do next?

Do you hear the startup chimes?
If so, then the startup disk may need repairing ...
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
Make sure to back up all important files first before using OS X Recovery.
OS X Recovery does require a broadband high speed internet connection.

I just upgraded to 10.6.7 and now my MacBook is constantly freezing, freezes even on login screen

I just upgraded my MacBook as it was not detecting external displays. Since the update it is freezing when it ha never frozen before. I have 4 gb ram and the computer froze for 20 minutes at the login screen when I started to type my password. When I finally Logged in I tried to open mail and the whole thing froze completely for another 20 minutes. I have never had this problem before and I have an assignment I need to finish tonight :( what can I do to stop the freezing? Under activity monitor it only says 8% usage yet I can't even open firefox without the computer turning into a paperweight.

Also put your install DVD into the drive and reboot.As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the optical drive.
Once it has finished booting and you are at the Install screen launch Disk Utility from the Utilities menu.
Then select the First Aid Tab and run Repair Disk and if that repairs any problems run it again until the green OK appears and then run Repair Permissions.

Both Chrome and Finder seemed to freeze, so I restarted the computer. When the restart finished, I was in recovery mode. How do I get back to my regular login screen?

Both Chrome and Finder seemed to freeze, so I restarted the computer. When the restart finished, I was in recovery mode. How do I get back to my regular login screen?
It starts up and asks for a language. After English, it goes to the OS X Utilities screen. I have gone to disk utility and verified the disks. They both say they are okay. If I click repair, it comes back with an error saying "Live file system repair is not supported." I just want my computer back to normal! Please help! I am still in Mavericks if it matters.

Do you have a backup? If so, in the Recovery Partition go to Disk Utility/Erase, select Mac OS Extended (Journaled), click Option GUID, and erase the disk. Then re-install the OS. Reboot and use Setup Assistant to recover your data.

System freezes and restart after user login screen shows up

The interesting thing is thing is that the same thing happens on the bootcamp partition. Every time I turn on MBA mid 2012, when the login screen shows up, the computer freezes and than turns off. Same problem when I boot into bootcamp partition, the computer turns on, pass through windows logo and after the login screen shows, it turns off.
...forgot to mention that it's running osx 10.9
I figure out that I can log in with Sage Mode. Every time I log in with Safe Mode, the error popup message shows up saying about the error and its log. There is the log:

Any ideas?

Problem solved... Figure out that in Safe Mode, the bootcamp partition is unmounted. So I thought that it could be the problem, when the login screen shows up, I guess the system was trying to mount the bootcamp partition and for some reason the computer was restarting. That's why the computer was turning off when I was trying to log in into Bootcamp partition also. So I wiped my bootcamp partition and resized the OSX partition. Now I can succesfully log in my user with out a problem

Screen Sharing via iCloud on Lion Freezes at Login Screen

After updating to OSX Lion 10.7.3, screen sharing between two computers via the Internet allows me to connect to the remote computer and see the remote user's login screen, but as soon as I click on a user to login, the screen share image freezes before I can enter the user password.
Using iCloud Back to My Mac because all machines have the same Apple ID & password. Exact same setup worked before the 10.7.3 upgrade, but it could be coincidence.
Details:
Can see the remote computers in my finder,
Can click on them and connect successfully using either the Apple ID or the name and password a user that is allowed under Sharing -> Screen Sharing,
When clicking on "Screen Share," the computers connect and I'm prompted to either "Ask to Share the Display" or "Connect to Virtual Display"Since there really isn't anyone using the computer, I select "Connect to Virtual Display"
After clicking "Connect to Virtual Display" the Screen Sharing window shows the remote computer's login screen, whcih shows the user names, their icons and "Sleep" "Restart" or "Shut Down" on the bottom of the screen. One user has an orange circle with a white checkmark next to it.
Previously, I could click a user's name or icon, enter the password and control the remote Mac. Now, not amount of clicking works.
Have tried disconnecting and reconnecting as different users or using Apple ID without changes in the perofmance. Have restarted both machines.
Any help?

I'm having the same problem screen sharing to a Lion 10.7.3 machine, I get this message.
However, it works just like it used to when I screen share from a 10.7.3 machine to another Mac running 10.6.8.
Any thoughts?
Thanks!

Screen freezes after login on Lion OS X (intermittent)

Ever since upgrading my MacBook Pro (purchased Apr-10) from Leopard to Lion I'm experiencing an intermittent problem where the screen freezes once a user has logged in. The problem only occurs when the machine is started from off and doesn't occur when starting from sleep or when switching users.
This problem affects all users set up on this machine and results in a cursor that can still be moved but can't select anything and a keyboard that is unresponsive. Most times the cursor shows as the coloured wheel. I have left the machine in this state for over 30 minutes to see if it would recover but it doesn't and I have no option other than to perform a hard reset by holding down the power button. Sometimes it can take a couple of hard resets before the machine recovers.
The configuration of my machine is fairly straight forward with an Apple Time Capsule providing backup and WiFi and minimal software installed.
I have found that disabling all 'Open At Login' apps reduces the likelihood of the problem but doesn't cure it.
Has anyone else experienced this problem and can provide a solution as I want to avoid having to revert to Leopard if possible.

Accelerated Video Drivers for the 5770 and 5870 first appeared in 10.6.5, so when running 10.6, be sure to update to at least that version before drawing conclusions.
Otherwise, I think your conclusions that this is a graphics card problem are likely correct. Over a very large sample, these cards have been much more reliable than many previous cards. But you do not have a very large sample, you have one card.
The Mac Pro (65lb tower) uses Error Correcting Code memory, so this is NOT a RAM memory problem or you would be getting kernel panics with machine check, uncorrected error.
Apple hardware test is a tool that only seems to detect the grossest of errors. It is famous for false negatives.

Macbookpro freezes when i enter password at login screen

Over the weekend I had an issue with Security Update 003 and Adobe Version Cue CS2. That got resolved and I no longer had any startup issues, but now I have them again, only they are a little different. My computer froze while converting a Photoshop file to PDF so I resarted then got to the login screen and as soon as i begun typin my password the computer froze. if i am very quick i can enter the password, but then it freezes on the logging in screen with the progress bar (not the starting mac os X one, i get past that). i can use safe mode, but i really need access back to full mode. I have removed all startup items so it is not that. also, my computer doesnt pick up airport any more, since the crash today. so i cant use the internet in safe mode. it says my airport status is "No AirPort Hardware Found". I was using it literally seconds before the computer froze during the conversion to PDF?
Thanks for your help
