Mouse freezes in login window (reproducible)

Hi,
There are numerous "mouse freezes" topics but I didn't see this exact one. I'm using a ms usb/wireless mouse. It worked fine pre-leopard/tiger. If I continuously move my mouse after I select the "Login Window ..." (from user name of menu bar), the mouse freezes (i.e., the pointer will not move) when the login window appears.
I have to shutdown and restart the mac in order to free up the mouse.
I have a couple of questions and remarks:
1. Is there another way to unfreeze the mouse?
2. I've done a restart (command-control-power) but the mouse is still frozen.
3. I've tried resetting the PRAM and the SMC but problem persists.
tia.
rollin'

I have the exact same issue. Sometimes logging out (shiftoption+commandQ) works for me... but yeah, it's really annoying. And my mouse is a USB Apple Mighty Mouse.

Freezing at "Login Window starting"

Hello, my PB won't get past login screen. It freezes specifically when it says "Login Windows starting".
Apple Hardware Test comes out fine but I can't repair using Disk Utility (the disk or permissions). Haven't tried Disk Warrior yet. I've tried starting in Safe Mode to no avail. I tried resetting PRAM and PMU with the same result.
Is there any other possible solution to my startup woes before I concede defeat and take this bad boy in to an Apple store?

I'm sure you're ready to turn in the computer for repair or troubleshooting but I have a couple of suggestions if you haven't tried them already. First, when you open Disk Utility from your installation disc, on the bottom after selecting your hard drive, what does it say next to S.M.A.R.T. status? Does it say "Failing"? My experience is that this finds problems with hard drives better than Apple Hardware Test. If it says "Verified", have you tried to re-install your operating system, either "Archive and Install" or "Erase and Install?" I would attempt an Archive and Install first, then an Erase and Install and see how that goes. Good luck.

Keyboard and Mouse Freeze On Login Screen

Hey there,
after just turning on my macbook pro 10.5.6 i am not able to use the keyboard nor the mouse to login, they are like froze, however the system is not. the writing cursor blinks in the password field, and the only button that works is the power button which i can press but cant use the keyboard to navigate, so i have to force shutdown. i can use keyboard to get into safe mode, where the same issue is found. and when i boot into single user mode, i am not able to use the keyboard. i also have tried attaching external keyboard and mouse, also no luck. However when i boot from the mac recovery discs, i am able to use both keyboard and mouse. Please if anyone can help me, i dont want to lose my information due to a restore. Thank You So Much Merry Christmas And Happy New Year!

lol sorry about that.
ok here is what i tried:
1) using the recovery disks to repair disk and permissions.
2) remove battery, press power button for 5 seconds and returning battery (weird, i read it on google)
3) long press power button
4) resetting the pram
5) tried attaching external keyboard and mouse
6) tried to enter single user mode however keyboard does not work in it to try some commands, also tried external keyboard, same result

Skype freezes on login window

please help me

Try now to uninstall IE11 and let Windows to revert your Internet Explorer to the previous IE10 or IE9 version.
In order to uninstall IE11 you should go to Windows Control Panel -> Programs and Features -> View installed updates -> Microsoft Windows -> Internet Explorer 11.

Login Window's Name & Password dimmed & freezed when trying to log in...

This problem keeps cropping up quite frequently, especially if I logged out of a OD account and immediately logging into another OD account: the name and password entered will dim and the Login Window will just freeze. There is no problem for local accounts and I still can SSH into this "frozen" computer and reboot the system. It occurs on all my Mac computers running Mac OS X Tiger (10.4.11) whether it is PPC or x86.
Looking at that "frozen" computer log, a successful loggin in will include these lines in system.log:

What is the server (model & specs) & what are the clients ?
Fast clients with a slow server can be one problem, due to how fast OS X boots.
See
Past that, since you can ssh into a frozen client machine, set this up in advance on a couple workstations.
On the client set AFP debugging via, for example:
sudo defaults write -g com.apple.AppleShareClientCore -dict-add afpdebugsyslog -int 1
sudo defaults write -g com.apple.AppleShareClientCore -dict-add afpdebuglevel -int 6
afpdebugsyslog = 1 (turns on debugging)
afpdebuglevel = <1-8>
Then, add the following line to /etc/syslogd.conf
*.debug /var/log/debug.log
Final two steps:
issue
sudo touch /var/log/debug.log
and
sudo killall -HUP syslogd
Then, try logging out and back in with a different usernameloginwindow, and check debug.log
and system.log on that client machine.

Mouse doubleclick sometimes quits apps, opens login window?

Occasionally, after doubleclicking my mouse (left click of Mighty Mouse), hatch marks in a circle will appear in the center of the screen and then the login window will appear. After I log in, the applications I had open are all closed.
The last time this happened, I was using Firefox, and had clicked a browser window behind the one in front, and when it did not come to the front immediately, I clicked on it again. There was a bit of a pause between the clicks. It's happened like this before, but I can't swear to what application's window I was clicking on, or if it was the desktop.
I can't replicate the problem; it seems to occur randomly. For example, I just opened two windows in Firefox, and the first click on the window beneath the open one brought it to the front. Even if I try doubleclicking on the window underneath quickly, it only brings it to the front.
Why might this be happening, and what might the solution be?

This just gets weirder. Originally it seemed it happened sometimes with a left doubleclick. Then, still randomly, with a single left click.
Now it happened when I was scrolling down with the scroll ball. There's no rhyme or reason to it. I can scroll down with the ball now, and it doesn't happen again. This is very strange and annoying.

Login window mouse tracking speed

Hi I was just wondering if there was a way to make the tracking speed of your mouse faster on the login window. I have made the speed in my account as high as possible through terminal and was wondering if there was any way to do this for the login window. Thanks in advance.

That's a setting of the root account.
If you're familiar with the setting via terminal for your own account, you might just be able to do it via terminal but for the root account.
Otherwise, you need to enable the root account. Login to the account, adjust the setting, log out, disable root again.

MBP mouse freezes in XP pro after 2nd login

ok, MBP is working perfectly, its a great machine, but i am experiencing a weird mouse freeze whenever a 2nd user logs into my machine.
for instance, i have 2 accounts, my account and a guest account.
if i login and lock my computer and walk away, if the guest logs in, the mouse will freeze.
i need to hard reboot to get the machine back.
on restart, if guest logs in first, then locks the computer, and i try to login, mouse is frozen and i must hard restart again.
anyone experiencing this problem as well? very strange.

I have the exact same issue. Sometimes logging out (shiftoption+commandQ) works for me... but yeah, it's really annoying. And my mouse is a USB Apple Mighty Mouse.

Mouse Freezes

I have a Mac running 10.8 and my mouse freezes after a period of time. The only that I can unfreeze it is to restart the computer. Any suggestions for a fix?

If this is an Apple Mouse, that'd be my forst suspect, do you have another to test with, but...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for mouse problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Login window crashing

Hello, I'v got an odd intermittent issue.... After entering my (correct) credentials into the login window the login window appears to freeze and prevents login.
I can move the mouse just fine, but the loginwindow becomes unresponsive. Trying other accounts on the Mac yields hte same results. I can drop into a shell by logging in as >console and I can login just fine in through safemode. This had me suspecting thrid party addins, but the problem persists when all addins (that I could find..) are disabled. This problem origionally happened a month ago and the fix was to remove third party launche agents/darmons. However the problem surfaced again today with some weirder results. The loginwindow froze, I sshed in and triggerd a reboot. The next login attempt caused iCal to pop up through the frozen login window (I also opened quicktime and got a screen recording). I was able to get terminal open via spotlight. I launched Finder manually, but I couldn't get the dock to open. This problem is really annoying becuase I was using my laptop all day without issue.
Throughout, the way I've been toubleshoot this I would ssh into the mac from another Mac and grabbed the contents of system.log (below). I can see loginwondow crashing out in the log. I can also "kick it" with launchctl but I get the same result.
I've also all of Onyx's cleaning routines, manually purged Cache and Application Saved State folders, repaired permssions, and ran Daily/Weekly/Monthly tasks to no avail.
I don't really don't want to reinstall Lion if at all possible, any advise would be great. Thank you!

Oddly, I can still login just fine after re-installing fresh copies of said plugins and preferences...

Login Window starting problem

I just got a iBook G3 Dual USB for Christmas and it had 10.3.3 and i upgraded it to 10.3.9 and now all it does is boot to the loading screen and wont get past the Login Window start part, the mouse is still moving so its not freezed. I also get cant boot into safe boot because the same thing happens. I dont have the restore/install cd either.

Colton.
You need to purchase a set of Panther 10.3.x installation discs.
By using the Jaguar 10.2.x discs, or model specific discs on the iBook, you may have further compromised the system.
Tiger is available for purchase at The Apple Store (U.S.).
Panther, is no longer available directly from the Apple Online Store, as Tiger 10.4.x is the most up to date OS.
A Full Retail Version, of the Panther Install CDs, or a Full Retail Version, of the Tiger Install DVD, can also be purchased rather inexpensively, at some online Apple retailers, Amazon, eBay, AppleRescue, FastMac, etc.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Panther is only on CDs, not DVDs.
The discs must look exactly like the images in the above links.
Additional info in these links.

Software Update, Upgrade: What's The Difference?
Once Panther 10.3.x is installed, you can use the 10.3.9 Combo Update, to upgrade to the final version.
If your Mac meets the System Requirements for Tiger, you could also consider installing that.
And then use the PPC 10.4.8 Combo Update, to upgrade to the current version.

No keyboard at login window after logout

Hello all,
I'm just starting state testing and have been presented with a problem. When a student logs out of a machine in order to log into the testing account the login window won't accept input from the keyboard.
Bacground and details:
We have labs of computers using workgroup manager and open directory for management. In a normal lab the machine will boot to a login window. This is so that the preferences will be refreshed before a student logs in. The student will login as a local user (student) and procede to do whatever for the day.
We have recently started state mandated testing. I have set up an OD account which is very locked down and keeps the student on track while testing. This requires someone to log the normal user out and login as the OD user. This is where the problem arises.
About 50% of the time the keyboard will no longer funtion after logout. No keys of any sort work. The mouse still works. Even keystrokes through ARD do nothing. A end user is then required to reboot the system in order to do ANYTHING. This is not ideal for elementary kids.
From my digging in log files and poking around i noticed that the loginwindow process was hanging or crashing. If i kill the process the login window blinks and then works just fine. I'm sure i could write a logout script that drops a process into the background to kill the loginwindow process after so many seconds, but thats messy. Has anyone seen this? Any thoughts or solution? Only happens on a logout, never on an initial bootup.
I have found that 95% of these issues occur on Mac Mini's. I can consistantly replicate the issue on a mini. If i clone the mini to a macbook, i no longer have the problem (using carbon copy cloner). So either the hardware is part of the issue or the clone fixed something in the process.

In those cases there may be threads and/or processes trying to do things with windows that they don't own. In other words, some programmers may have goofed up a little bit someplace.

Login Window on Wrong Screen in Dual Monitor Setup

I have two monitors attached to my MacBook Pro running OS X 10.10. When I boot up with the lid closed, I see the start up sequence (Apple logo and progress bar) shown on the monitor that is my "primary" monitor of the two monitors. But when boot up is complete and the login window appears, it shows on the secondary monitor, not the primary. My primary monitor is connected via Thunderbolt, and the secondary monitor is attached to the HDMI port on my MacBook Pro. Any ideas how to set the login screen to show up on the primary monitor?

I have exactly this same issue on a Late 2012 Hexacore Mac pro (The last real one LOL)
My primary screen (a 24inch VGA 1080p monitor) shows the Apple boot logo (with progress bar) whilst the secondary display (32inch HDMI 1080p LCD TV) is plain white
then when the initial login box appears that comes up on the 2nd display (Even if it is turned off) meaning I have normally have to turn that screen on, log in then turn it off again
I have also noticed that the screen layout is wrong. Once logged in the 32" display is logically located above the 24" one. However for the login dialog they default to side by side. meaning movingthe mouse up to the TV to log in means going left ot right... Not very good really.
Not enough to make me revert to Mavericks from Yosemite, but still quite annoying.

IMac won't start up: No login window appears.

Hello, there, everyone. The problem I'm addressing here is that my iMac is simply refusing to start up. Two days ago I turned it off (because of irrelevant problems), and since then it just won't boot up completely. Whenever I turn it on, it loads past the blue and white loading screens and the grey Apple logo, but once it loads the default Apple wallpaper it won't go any farther. No login window appears, preventing use. I've tried various alternative ways of booting it up, but nothing seems to work. I've tried safe-booting it (Which really doesn't change anything), initiating the Apple Hardware Test (Which freezes once I choose a language), unpluggung the computer both when it is on and off and retrying the start-up sequence, but still no progress has been made.
My iMac is about four years old, which isn't exactly a short life for a computer, but it still surprises me to encounter such a major problem. If anyone would happen to have any experience with this situation, I would be very greatful for any help at all. Thank you in advance.

Three beeps usually indicates failed or no ram. Try removing and reseating all of the ram. If that doesn't help and you have access to another mac can you start the imac in Target Disk Mode? OS X Mountain Lion: Transfer files between two computers using target disk mode
You'll probably need to take it in for service, but hopefully you aren't about to learn the hard way about backing up.

Mouse freezes in login window (reproducible)
