Cannot Login after 10.4.11 Upgrade

I recently upgraded my G4 Quicksilver Power Mac from 10.3.9 to Tiger. The install DVD was for 10.4.6. The DVD installed fine, then I ran the system updater to get the remaining 10.4 updates. It updated Java no problem, then the Mac OS X Update Combined (PowerPC) came back with an error saying the digital signature is incorrect. I then went to the Apple Support Downloads site, and attempted to download an update with Safari. I tried the combos for 10.4.8 thru 10.4.11, and all of them failed verification after attempting to open the download. Very strange. So I went to my macbook, downloaded the 10.4.11 combo update ok, and put it on the G4 with a thumb drive. It opened the dmg file fine, I ran the update, and the system re-booted. At some point before the login screen, it hung up and I had to power it down. After restarting, it now gets to the login screen, and sits there until I move the mouse pointer into the login window. It then hangs there with the spinning beachball. I'm not able to login at all. Same problem when booting in Safe Mode. I've used the DVD to startup the system, and can access the HD using a terminal window. I ran the disk utility, and the HD is fine. I looked at the system.log and don't see anything there that I can identify as something I can fix. There is a segmentation fault at time 22:57:47. I'm including the log below, maybe someone can get something from it. I thought I'd try to re-install the 10.4.11 combo update, and haven't been able to mount the dmg file while running off the DVD. To do that I need to create a root directory on the HD, but it's read-only when running from the DVD. While in the hung login state, I cannot remotely login to the G4 using ssh from my macbook.
So at this point I'm stuck short of trying to re-install from the DVD using the option to archive the current OS before install (the installer recognizes that it is now at 10.4.11, and so it won't do a normal simple install again.) I'd really like to try to fix what is there or figure out how to re-run the 10.4.11 update, before doing the archive/install/10.4.11 update again. Don't want to do all that and end up in the same place.
I'm hoping someone can give me some ideas. Below are the system profile and the system.log. Sorry for the long post. Thanks!!

Have you tried starting in Safe Mode (hold shift key down while starting, be very patient).
[Mac OS X: Starting up in Safe Mode|http://docs.info.apple.com/article.html?artnum=107393]
[What is Safe Boot, Safe Mode? (Mac OS X)|http://support.apple.com/kb/HT1564]
[Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
[Mac OS X 10.4, 10.5 - Computer shuts down during Safe Boot|http://support.apple.com/kb/TA24054]
Safe boot mode runs a directory check command similar to that used by Disk Utility's repair. In Tiger it ignores some stored information (cache) that is normally read that speeds up the boot process, and it moves some other caches to the trash. It also uses only System fonts and disables all Startup Items, third party items, and any Login Items.

Failure: Cannot login after Lion 10.7.2 update

I cannot login after performming the update realeased today.
After boot, at the login screen, I see the user in the circles. Upon selecting a user, entering the password, the spinning circle below the Apple appears. It spins for a few mnutes, then return with a NOT symbol as the spinner contues to spin endlessly. After a while, the fan kicks into overdrive.
I tried to do the boot in recovery, start terminal, resetpassword, restart, login as root steps, but do not see an option to login as root upong restart - just the User circle icon.

I have a similar problem, but it looks like I have solved it.
I rebooted holding down ommand-R to get to the recovery-HD mode. From there I chose the options to re-install Lyon (requires internett access because it downloads a new copy).
Since I have multiple disks attached (the internal and a bootable backup drive) it asked which disk I wanted to use. When I chose the internal drive it told me it was locked and asked for the FileVault unlock code. After that things seemed to proceed properly.
I suspect that the problem is in some way tied to my use of FileVault.

Folio Builder - cannot login after changing password

Hi all,
I changed my password at acrobat.com, now I cannot login with the new password from the Folio Builder panel in InDesign CS5.5. I'm on Mac OSX 10.6.8. Basically, the panel shows "Signing in..." and the endlessly spinning wheel, which means it's hanging and doesn't let me re-enter my login credentials.
I have tried uninstalling and reinstalling the Folio Builder and Overlay Creator tools, and am running the latest versions of each.I've also tried trashing the INDD preferences. No luck. I'd like to avoid uninstalling/reinstalling InDesign CS5.5, but if that's the only solution, I'll do it.
I did create a new user on my machine and that worked — I was able to login successfully with my new login credentials. But moving my production files and recreating all my settings from my account to this new one would take a while, so I wanted to see if there was another solution.
Thanks in advance for any help!
Jason

Hi John,
Yes, I can login successfully there. The problem also appears to be with the CS Review and Access CS Live panels in InDesign.
When I initially open the Folio Builder, I get the error dialog "Sign In had failed. [svr.InvalidLogin]". The CS Review and Access CS Live panels also report an internal error.
This happens in both InDesign CS5 and CS5.5 (both installed on the same computer). Could the CS5.5 and CS5 panels be sharing that info? I haven't uninstalled/reinstalled the panels from CS5, just from CS5.5, which might explain the error, if I need to also uninstall the CS5 panels/extensions.
Thanks,
Jason

Cannot login after upgrade

Seems to have been covered elsewhere, but not quite the same issue.
Updated to latest verison of Snow Leopard on my MacBook Pro and Mac Pro in preparation for installing Lion.
Installed Lion on MBP which all went perfectly and been using it for a week without problem. So, time to install on the Mac Pro.
First, installed it on a blank external disk connected to Mac Pro, as an emergency disk. At the end the MP would boot from that drive and I could log in with the single admin account that I had created. Looking good so far.
Rebooted into SL and installed Lion again, but on the main disc. No errors and was finally presented with the login screen, listing all the correct users. Selected a mobile user account (account is on local SL server) and I was able to type in the password, but then when pressing return (or clicking arrow on RHS of text box) the arrow is replaced with a spinning daisy wheel which spins forever.
Logged in remotely (which works fine) and rebooted machine. Tried to login with a local admin account, but same problem. I can however login in with the Guest account, but if I try to switch users to another more useful account, it's just a big grey blank screen.
So there is something up with Lion being able to log in to those existing accounts.
I tried to boot into safe mode (from the main HD), I get the progress bar which seems to be Lion's way of saying it's starting in safe mode, but then a while after the progress bar completes and vanishes, it reboots all by itself. If i just let it boot and try and login, I'm stuck again (it's obviously NOT in safe mode) and if I hold down shift again while rebooting, I get the progress bar and eventually another auto reboot and so on. IOW, it is NOT possible to fully safe boot.
Since the MBP contained the exact same accounts and it was bouind to the same server when it was upgraded, I cannot understand why it's such a problem on the MP, yet working perfectly on the MBP. Anyone shed any light on this?

Since my original post, I've re-installed Lion, but no improvement. I then clered out the caches as indicated elsewhere - no change. I then noticed that the Little Snitch utility was exiting and respawning continually so I moved out all LauchAgents and LaunchDaemons except for an Apple one for disc repair that also exists on my MacBook Pro on which I can login perfectly. The others did not exist on the MBP so I'm thinking they are the cause.
Even though I now don't have the error messages in /var/log/system.log about Little Snitch, it still gets stuck in the same place with the following entries:
Aug 8 19:08:17 macpros SecurityAgent[118]: Login Window login proceeding

Cannot login after upgrading to Apex 3.1.2

I have installed the oracle-xe-10.2.1-1.0.i386.rpm onto a RedHat server using
]# rpm -ivh oracle-xe-10.2.0.1-1.0.i386.rpm
Then I configure the database
]# /etc/init.d/oracle-xe configure
Then I enable remote access
EXEC DBMS_XDB.SETLISTENERLOCALACCESS (FALSE);
This appears to work properly and I can log into the Apex page at http://server:8080/apex/apex_admin
After this install I'm attempting to upgrade to Apex 3.1.2 and have attempted this several times. Each time, the result is that I can bring up the web page, but cannot authenticate. All that I see is "error on page" at the bottom left of the window. (IE6 or Firefox).
To complete the upgrade I do the following.
]$ sqlplus /nolog
SQL> @apexins SYSAUX SYSAUX TEMP /i/
After the install runs the last few lines are
Upgrade completed successfully no errors encountered.

After all of this appearing to run successfully, I cannot log into either the basic apex screen or the apex admin screen.
When it has failed, I have uninstalled the RPM and deleted the remanant folder.
Then re-installed from scratch.
I'm new to oracle, and any assistance would be appreciated.

Hi Fred_Oregon,
Usually the only reason it will ask you to reboot is if there is a file that must be modified that the updater doesn't currently have access to. You should try running the Firefox program once as Administrator:
* Right-click the icon and choose ''Run as Administrator''
If that doesn't help then do a clean reinstall.
# Download a fresh copy of Firefox from the [http://www.mozilla.org/firefox/fx/ Mozilla download page] and save the file to the desktop.
# [[Uninstalling Firefox|Uninstall]] your current version of Firefox and remove the Firefox program folder before running the new installer.
# Run installer
Remember that you don't want to remove personal data when uninstalling. That way you'll still have your personal information.
Hopefully this helps!

After installing Yosemite, cannot login after wake from sleep mode

After upgrading to Yosemite this morning, I've had the problem that after the computer goes into sleep mode, I cannot log back in to use the computer because I can't enter my user password. The screen looks fine after I press a key on the keyboard or move the mouse (I see the users and where I would type my password), but mouse clicks do not allow me to activate the password box (however, I do see the mouse pointer and can move it), and any buttons pressed on the keyboard have no effect. If I shut the computer down, I can login without problem. Any thoughts on how to resolve this? I'd hate to have to turn the computer off every time I step away for 10 minutes...

MYOB cannot print after 10.4.4 upgrade

Hello ALL
I have tried various solutions to solve this (including those in another post).
Using iMac G5, MYOB Acc+ V14, OS10.4.4, HP Laserjet 2600N, Canon iP4200 inkjet.
All was OK until the upgrade, now every app will print apart from MYOB.
Tried repairing permissions, running MYOB from Desktop, removing prefs, re-installing printer drivers, re-installing MYOB and I have now given up.
Anyone?

Answering my own thread here, but in case it helps anyone here.
I have solved my problem, with the help of MYOB and this might apply to others.
Apparently in the 10.4.4 release either the location of the actual fonts that are installed have changed, seems to effect Optima and Palatino in my case. The forms I was trying to print contained these fonts, but MAC OS has changed them and my font manager did not have them active.
But, MYOB was not reporting the missing fonts, instead my print jobs were just disappearing.
So, I made sure that my font manager kept these two fonts active, even after quitting, problem solved.
Or, if you cannot do this, just experiment, with the file you are trying to print, change the font to TimesNewRoman or Arial and see if that sorts it. If it does, you are going along the right lines.

Cannot Print After Installing Latest Security Upgrade

Yesterday I downloaded and installed the new Security Upgrade from Apple. Today after restart I cannot print with my Brother HL-1440 printer. I downloaded and reinstalled the printer driver. Still doesn't work. Thank you Apple.
Any suggestions will be appreciated.

Blawrimore,
Have you had a chance to read through the support docs at the Printers website?
I found these two that may pertain somewhat to your problem that you may want to look at:
http://solutions.brother.com/Library/faq/printer/prfaq0797/prfaq0797.html
and
http://solutions.brother.com/Library/faq/printer/prfaq0796/prfaq0796.html
Looks like you are supposed to delete unnecessary printer drivers of other manufacturers and to be sure you "reselect" the printer in Print Center after downloading their drivers.
And, I'm sure you downloaded the correct driver, but certainly wouldn't hurt to double check that it is the correct driver. (that sounds like something "I" would do.....)))
Sorry if these don't help any,
littleshoulders [:-)

Cannot Login after installing Leopard

Hello,
I just installed Leopard, and after restarting I had the "blue screen" problem. I followed the instructions (removing the the "ApplicationEnhencer.bundle" file from the troubleshooting section on the Apple website), and after restarting, I was able to acces the login page.
After entering my personal password, I had the following message: "you have to restart you computer by pressing the start switch for several seconds".
The only thing I can do is to login via other users of this computer but I cannot access my own account anymore!
Can somebody help me?
Regards,
Lins.

Cannot Login After 10.4.8 Update!

I just updated my Powerbook G4 Titanium to 10.4.8, and I can no longer login to my computer. My password uses normal characters, and when I enter it, the login screen disappears (as if the finder was going to load), and then it suddenly REAPPEARS, prompting me for the passoword again. I am 100% certain that my passoword is correct, because when I attempt to enter something else, it merely shakes and re-prompts me on the spot. Any ideas, anyone? I have attempted to start-up in safe-mode, single-user mode, and from a Software Restore CD, but unfortunately I cannot. Does this mean that I have open-firmware running on my system? Any and all advice appreciated,

Hi, Gideon.
1. Have you verified that the Caps Lock key is not enabled? Any symbols appearing in the right side of the password entry field?
2. You wrote: " I have attempted to start-up in safe-mode, single-user mode, and from a Software Restore CD, but unfortunately I cannot."I'm trying to put your statement here in context with the password/login problem. Are you saying that (a) you cannot log in when you start up your Mac in these other modes or (b) that you simply cannot start up your Mac in these other modes?2.1. If (a), An errant Startup Item maybe the cause. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem: focus on the testing of Startup Items.
2.2. If (b), then I suggest you:2.2.1. Run at least steps 1-3 of the Procedure outlined in my "Resolving Disk, Permission, and Cache Corruption" FAQ. You may be getting the timing a bit off in terms of holding the C key to startup from your Tiger install disc.
2.2.2. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
3. If your account is the only account on that computer, then your account is also the Admin account. See "Mac OS X 10.4 Help: Changing your administrator password."
4. re: Open Firmware: If you've enabled Open Firmware, you should see the image noted in "Setting up firmware password protection in Mac OS X 10.1 or later" when you attempt to startup from the install CD.
Good luck!

Cannot login after awaking from sleep (login screensaver sleep problem)

After awaking from sleep or returning from the screensaver, the "loginwindow" of system.login.screensaver (visible after checking "details") does not recoginze the correct password. It is not possible to login this way anymore.
Very annoying!
Fortunately, I found a workaround using the functionality to switch users. The standard OS X welcome screen recognizes my password.
Anyone experiencing the same or with a way to correct the initial problem?
PS: the user account in question is a "network user"; it works as expected for a local user

More info:
It seems to be the screen going to sleep, not the computer. When I come back and touch the mouse or the keyboard, as the screen lights up, there is a flash of the web pages I left up, then they vanish.
Yikes!!!

Can't login after 10.5.6 upgrade

Yesterday I upgraded my iMac 2 GHz to OS 10.5.6. It worked fine in the beginning, but today the Mac started to behave slow and strange (couldn't click on anything). I had to force quit. But then I couldn't login again. When the login window appears, I can't choose user or enter my password. If I force quit, the startup process comes to the same place, but not any further.

Cannot reboot after 7.1.1 upgrade...help!

I just downloaded the latest upgrade 7.1.1 to my Imac desktop. My computer restarted on its own in safe mode. After watching the 'gray bar' complete its process for 20-30 minutes, my computer shut down automatically. After several attempts, it will not reboot, just repeat the same process. I restarted in recovery mode and used my Disk Utility checking my volume using repair disk with nothing noteworthy...still no luck.
Anyone having similar issues after recent upgrade? Anyone have a solution for me??? Please!?

The iOS is for iDevices and will not run on a Mac computer.
The Mavericks OS X 10.9.2 is the latest system available to Mac.
There was a security update a few days ago, for several items.
So you must be referring to something other than the OS X.
What does 'About this Mac' say?
Did you try SafeBoot, or use OS X Utilities to run Disk Utility
and repair disk/repair disk permissions, to check/fix startup?
It may need more, depending on what is really going on.
Details are everything.
Good luck & happy computing!

10.7.2 clean install: cannot login after sleep

so after getting bricked this morning, I have done a new clean install of Lion, updated to 10.7.2 and went to work. back I come, Mac is in sleep, and it does not accept my user password anymore.
just great.
no file vault on this time.
10.7.2. is pure nightmare for me so far.
force reboot let me boot again (and log-in!).

I have the exact same issue- any help on how to fix this would be great.
In the meantime - I have found a workaround which is a bit of a pain - but allows you to keep your session going.
1) When you come out of sleep and don't have the option to use the fingerprint login and the password doesn't work click on "switch user"
2) When that screen comes up click on the arrow next to the red (shutdown) button and select "hibernate".
3) After the machine hibernates resume windows by hitting any key
4) You should now be able to sign in using your account password and resume your session.
This is not ideal - but until someone can come up with a real fix - it works and allows you not to have to restart windows and lose your session data.
