No mouse or keyboard at login screen

My Mac Pro has been running just fine until now....I JUST updated the latest security update today and when I restarted my computer, the mouse pointed won't respond nor will the keyboard respond to any actions so I'm unable to login.
The laser mouse has power to it via USB but the mouse pointer won't move.
I am able to use Screen Share from my laptop and control the computer pointer that way and login but after I login, the mouse is still inactive via the USB mouse that's plugged into the Mac Pro.
After about 5 minutes, it started to work again so I repaired permissions, verified the Hard Drive and ran some other standard things and then I restarted and the same problem came up again.
I'm stumped. Anyone have any suggestions?

PS,
when i reboot, the mouse pointer will always return to the top left corner. Same position. Every time.
I shutdown, then unplugged every USB connection, booted up ... then plugged back in my USB hub containing my keyboard and mouse ... the mouse was active but moving at a SLOW rate of speed (definitely not the tracking speed I have in set in my mouse preferences). Maybe this is a preferences issue?
Also, login is taking forever! I'm thinking there's some sort of issue behind the scenes? Can someone PLEASE help me out here. I'm under a deadline for work and this needs to get resolved but I'm unsure where to start even after doing searches. Most searches turn up "bluetooth" mouses but since I'm wired USB ... I'm stumped.

No bluetooth mouse or keyboard on login on MacBook

Dear experts,
Over the weekend I made a fresh SL install (plus update to 10.6.1) onto a new harddisk on my white MacBook2,1. Imported my old users from the old 10.5.8 harddisk. So far things have been fine except for one:
At the login screen my bluetooth Mighty Mouse and Apple bluetooth keyboard do not work. I have to use the MacBook's built-in trackpad and keyboard. After login both bluetooth keyboard and mouse will work fine. Over time it is annoying as I normally work with an external HD display and the MacBook is positioned across the desk.
I have already tried enabling and disabling the "wake from sleep" and "open assistant if no bt mouse/keyboard is found at startup" options in the bleuthooth preferences. No assistant will come up. As stated above, once I log in the bluetooth devices will work after a few seconds.
Under Leopard 10.5.8 the bluetooth peripherals worked for login as well.
It seems like the bt driver is only loaded after login. Is this a "feature" in SL or can it be helped?
Your help and advice is appreciated.

Yes, I already tried re-pairing twice: Once using the bluetooth assistant and the second time the options provided in the mouse and keyboard preferences (configure bluetooth mouse). Neither did solve the problem. I should have written that in my initial post, sorry.
When I searched the discussions for my problem before posting I did see that some users have bt problems. But my devices work fine, they do not "disappear" in normal operation. They are only not reacting at the login screen.
Is maybe anybody else using a portable Mac together with bt mouse & kb? I was already thinking that if Snow Leopard detects the internal trackpad and keyboard it does not try to connect the bt ones (as you only need one strictly speaking). But then once I log in they work both and also in parallel (internal and bt) as they did in Leopard (sans Snow).

Keys broken, need to enter Password? How to open onscreen keyboard from login screen?

I have a macbook (just the original white one...I want to say it's a 2008). I haven't used it in a while because my keyboard is broken. I had to have some work done on it (other than replacing the ketboard which I will do later), and when I got it back and cut it on, it came to the login screen where I need to enter my password. My password contains some of the letters on my keyboard that are broken. How do you open the on screen keyboard (where I can use my mouse to type it in) from the login screen? There's no options or anything that I can click on other than where I enter my password. Thanks in advance for any help!!!

I do not have an external keyboard...well I do, but I can't find it at the moment. So if there's any other way around it, that would be helpful

please help!
thanks in advance

1. I have tried copying the Keyboard/Trackpad/Mouse drivers to the $WinPEDriver$ directory with mixed success on a 2012 MBP.
2. My experience is based on a 2013 rMBP. You may be able to use an Apple USB Keypad/Mouse to better success.
3. See http://www.macworld.com/article/2460820/macbook-pro-mid-2014-review-minor-update -offers-slightly-better-cpu-performance.html for HW differences between the two machines.
4. If you have access to a 2013 rMBP, I can suggest trying to build the USB on that and working with the USB to see if you can make it install Windows. the rMBP 2014 and rMBP 2013 have the same HW, except some CPU changes. You can also try building the USB at the nearest Apple store, if possible.
5. There is a section in AutoUnattend.xml, which is supposed to install all drivers in $WinPEDriver$ (see this http://support.microsoft.com/kb/2686316 )

Macbook pro does not respond to bluetooth keyboard and mouse at login screen

i've seen this question floating around and i don't think i've found one that has been resolved. i'm hoping someone may have an answer by now.
i do not have this issue when i boot into windows 7 (bootcamp) the macbook pro responds to keyboard input and mouse input immediately on the windows 7 login screen. when i boot into mac, there is no response from either. i've seen suggestions of waiting for 30 secods. i still get nothing after waiting for over a minute.
what i do right now is use the built-in touch pad and keyboard of the macbook pro to get past the login screen. once i'm logged in, i can see that the bluetooth devices are not yet connected (the three dots that go across the bluetooth symbol at the top right of the screen are not yet there). then after a while, maybe about half a minute, the bluetooth keyboard and mouse are connected and i can use them normally.
it is not a big deal but it is very annoying.
i am using a logitech bluetooth mouse (v740) and an adesso bluetooth keyboard (wkb-4000bm). i also tried an azio bluetooth keyboard and had the same issue. all these keyboards are made for mac.
thannks in advance.

just a correction, the keyboard and mouse don't always automatically reconnect once i'm logged in. most of the time i have to go click the bluetooth icon at the top right of my screen, select the mouse and then select "connect". i have to do the same to the keyboard.

How and why did you install that? What steps did you take in that process. I can then help with some steps to undo them.

Stuck at login screen after Yosemite Upgrade - 2013 27" imac won't recognize keyboard or mouse

I installed yosemite without issues on my 2013 macbook pro retina so decided to try it on my 2013 27" imac. Install went fine until I get to login screen. Wireless keyboard and mouse won't pair so I can't type in password. Connected generic wired keyboard and mouse and still won't recognize it.
However, when I restart it I can hold down option on keyboard and it will bring up list of hard drives to boot from (I also have windows installed with bootcamp) so I know imac pairs the key

So the iMac was purchased by my father in 2011 shortly before he died. I thought, why not check if he also purchased Applecare at the same time? Turns out he did! So after calling and trying to reset the SMC, etc. with it not working the Apple tech told me to turn it over to an authorized repair shop here in Louisiana. Hopefully they can fix it.

Keyboard locked at the login screen

Hey all,
i have a problem with my macbook pro (late 2010), since updated from Maverick to Yosemite 10.10 and few days later to 10.10.1
i while using "normally" surfing, emailing has crashed my MAIL and few moments later the SAFARI. Thinking a restart always can
help i did it. But after the restart at the login screen the keyboard is (b)locked (i can moving the mouse cursor) but i can't type in any
in the password field. (by the way, i can't not open the screen keyboard)
If i go to the guest account, there i haven't password (because never used this account) there is working the keyboard. But i haven't
any rights to change something at the system. Please, anyone can help me, and sorry for my bad english. Any solution without lost
all my documents.
Thank you very much.
Daniel

Then you are not at the initial login screen - you are waking up the mac from having put the computer or display to sleep due to inactivity.
You are already logged in. are you certain you're entering the correct password?
Do you have another computer on the same network that you could try and login to your Mac via "ssh" from this other computer. If you do, login from the other computer in a terminal type window and "ssh username@IP_Address_of_Mac" and see if that helps (substitute username and ip address of the mac for the user and IP address of the mac). You can then do a "sudo restart" and try the safe boot and reboot. This assumes you had "Remote Logins" enabled in the Sharing System Preferences though so it may not work depending on how that is set now.
So you don't see any dots appear in the password field as you type - do you? Are you sure the Caps-Lock key is not active (your password is case sensitive so if the CapsLock is on accidentally then you will never be able to login this way until you turn it off). If the CapsLock LED is not working you have no way of knowing if it's on or off, so if one attempt at loggging in does not work (and you see dots appear in the password field as you type) then press the CapsLock key once and try again.
If you don't see any "dots" appear in the password box
Good luck...
ps - in any event you can always press and hold down the power button for about 5 seconds to force a shutdown but this can cause problems and not recommended except as a last resort.

I downloaded OS X Lion on my iMac and I'm having problems with my computer waking up after hibernating. I can get to the login screen but my mouse will be frozen. The only fix's is a hard reboot. Any help would be great!

Try resetting the SMC and the PRAM.
1. SMC
Read this and follow the instructions for your kind of mac:
http://support.apple.com/kb/HT3964
2. PRAM
Follow the procedure below:
1. Power down the machine.
2. Locate the following keys on your keyboard in preparation for Step 4:
command–option–P–R
3. Press the ‘power on’ button.
4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should normally.

Keyboard and mousse dont work on login screen, recovery failed to start

one of the best ever, im trying not to throw this laptop through the window . not because im being reasonable, but because I have shitty neighboors .
ok,
HP pavillion DV6 windows 7 , i7 core
1/ mousse and keyboard works fine before it shows the login screen.
     STOPS working both even when i connect USB keyboard and mousse on normal and safe mode
     the shortcuts on top of the keyboard still works though (screen light, volume control, wireless on/off ... etc )
2/ my recovery fail to start
3/ tried the battery thing stil mousse and keyboard NOT working
4/ I also managed to run command prompt with windows 7 DVD in french (not compatible) but helped me run
chkdsk C: /r /f
and
chkdsk D: /r /f
means hard drive is ok, but recovery still fail to start and asks to run recovery from windows CD (I dont have one, and I dont want to loose my windows license)
how to either fix recovery or keyboard/mousse
I fixed more than 500 pc in my life, I cant fix mine now

Hello zgued. I understand you're having some trouble with your keyboard and mouse.
If you were to reboot your computer and access the BIOS using the F10 button does the keyboard work there?
Which dv6 do you own? Identifying the notebook by the product number is the most helpful. This document can show you where it is located.
Have you ever taken the notebook apart? The symptoms you describe would fit with a damaged or loosened cable inside the notebook.
I feel that I should first help you troubleshoot the recovery issue. I say this because performing the recovery will rule out software issues with a 99% certainty. So, what was the problem you faced during a recovery? Do you get any errors?
I'll keep an eye out for your response. Have a great day!

Dear all professional in HP technical support team,

Then I try to boot in to Recovery mode, conduct dozens of Chkdsk command (chkdsk c: /R /X), turnout all bad sectors has been allocated and the Window finally can boot in to login screen.
However, I am unable to login to desktop since the USB HP wireless keyboard is not responsive, the USB HP wireless mouse work fine, and I am unable to activate 'On-screen Keyboard', I was manage to boot into safe mode, but it turnout the same, because the keyboard not responsive, I cannot input the password and login to both Normal and Safe mode.
I had try to attach a USB wired keyboard and USB wired mouse as well, it turnout the same, mouse is working and keyboard is not responsive.
The mouse and keyboard are working both recovery mode and BIOS environment.
Othe than Reset the PC, please advise is there anyway I can login to the desktop again, or I need to manually re-install the USB wireless keyboard driver from command prompt in Recovery mode.
Thanks for you help in advance.
Best Regard.

Hi again Bruch2168,
Thank you for the quick reply!
Since you are not able to return to a previous restore point in recovery mode, I recommend returning your system back to a previous restore point. This can be done by following the steps in this document on Using Microsoft System Restore (Windows 8).
Should the problem continue, I suggest performing a backup and recovery of your operating system. This can be done by following the steps in this resource on Backing Up Your Files (Windows 8), as well as Performing an HP system recovery (Windows 8). This should return your system back to factory defaults.
If the issue persists, please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Early 2009 MacBook Air. On startup no keyboard or mouse me to login. Neither is the USB working so I cannot use an external mouse or keyboard either.

Early 2009 MacBook Air. On startup no keyboard or mouse me to login. Neither is the USB working so I cannot use an external mouse or keyboard either. If I keep restarting the machine suddenly sometime I get mouse and keyboard control and I am able to login and work. After sometime though mouse and keyboard Control is lost again and the machine hangs.
Lately another problem has cropped up. Now the machine starts up and seems to work for longer time but I have no 0 key and USB everything else is fine.
What could be the issue

Macbook air with 10.10.1 keyboard and touchpad stop responding after login screen

Keyboard and touchpad works only at login screen.
I have tried all the PRAM and SMC. reset stuff.
Safe mode, repair etc. Creating another account is not helped either.
I am also using 10.10.1 with macbook air.
I have also called the apple tech support and no results!
And this is obviously a software bug from so called robust yosemite!
Same here!

Macbook air built-in keyboard/trackpad only work at login screen

The built-in keyboard and trackpad have become unresponsive on my 2013 refurbished macbook air. When I restart it, everything works normally at the login screen, but becomes unresponsive again once I've logged in. The computer works fine with external inputs or a shared screen.
I've recently updated to yosemite. The fact that everything works up until login makes me think this is a software problem. I've tried all the troubleshooting steps listed here, and I've reset PRAM and SMC. Does anyone know what could be causing this?

Hi,
I was able to get result from apple store after 24 days not hours days. They said it's my fault and they have found liquid inside of it and when i asked to see pictures of it they asked for COURT ORDER and repair will be cost around 400$.
I am %100 sure that my macbook air never touched with liquids.
I was using it for business and not even fluids there isn't any one scratch on it. I have been very careful.
Did they asked 400$ for you too ?
I am also using mac mini and iphone 5s. I think i will never buy an apple again.
And i will definetly go to court.

Mighty Mouse button doesn't work in Login screen.

When I boot up my Mac I can move the cursor with the mouse in the Login screen, but I can't click on anything - the buttons don't work. Once I'm logged in the mouse works normally in every way.
This only happens with the Mighty Mouse - 3rd party mice work fine in the Login screen.
I can't see any settings in the Mouse System Prefs that would affect this.
Anybody got a suggestion?

Nobody got any insights?
