Keyboard Problems, Control-Option-Command Keys Don't work

Hello and thanks.
Have a iMac 2.4ghz Intel Core 2 Due with 2GB of RAM running 10.5.8 and suddenly the control-option-command keys are not working on my keyboard.
Working fine and then suddenly no keys on my last row worked, including space bar. Scoured message boards and tried all fixes. Substituted keyboard with wireless (known working) and usb (known working) with limited results.
Initially the last row of original keyboard didn't function at all and command keys seemed locked so couldn't type. Only did modifier key functions (open, close, find, et.c)
The two different keyboards, wireless and USB, typed but the control, option and command keys don't work. Space bar works and the command key no longer locked.
Things I have tried:
1. Checked Universal Access settings so no sticky keys, etc.
2. Check Speech settings, all correct.
3. Replaced user, universal access prefs from point of which keyboard worked, no change.
4. Cannot zap PRAM due to no working option or command keys.
5. Reset SMU. Caused fans to go high speed. Unplugged computer from wall. Waited 10 seconds, replugged, fan now normal.
6. Repaired permissions.
7. Tried to repair disk but operation failed in middle of scan. Won't mount from any bootable CD.
Currently the wireless keyboard works fine except I have no control-option-command key usage. Keyboard types fine and all other keys work fine.
Suggestions? I'm very frustrated.
Thanks in advance,
Annie

Upgraded to 10.6. Problems resolved.

Select multiple channels for one task - control and shift keys don't work

Hi,
Following advice from several other posts, I'm trying to select multiple physical channels from the dropdown list so that I can then use the "unflatten channel string" function later on. It looks like if I hold down either shift or cntrl I should be able to select multiple channels from the list, however, this doesn't work for me. I tried going into the "key navigations" property for the task channel control but it doesn't have any associations listed. Has anyone else come across this and found a fix? I have previously got around this by stating multiple channels with a colon (eg. ai1:3) but this doesn't work for the unflatten function.
Thanks,
Claire.
Solved!
Go to Solution.

Thanks for your reply Dennis, I see what you mean, unfortunately that doesn't solve my problem so I'm missing something else. I've attached my VIs. I expected that the output from the unflattenstring block would be an array of either the channel references or the names I had given them, and that therefore the "array size" in the 4th pane would be "9" (equal to the number of channels). Instead the output is a an "unnamed task#(some number)" when I look at it with a probe. Perhaps I'm misunderstanding how the task naming works?
THanks,
Claire.

Apple Aluminum Wireless Keyboard Pairs, but letter/number keys don't work

I just got the new Wireless keyboard and I paired it, and the Function keys work fine, and when I was pairing, the number keys worked as well(to type in pairing code). But when I try to type in any search box or type anywhere, it won't. even the numbers won't work. the Tab and Delete keys work though. Along with the function keys.
The funny thing about this is that the number keys worked when i was pairing, but not now. Also when I start up my Mac and have to type the password in, the letter keys worked. But once on the desktop its a no go.
Please help.

24 hours later, the initial fix resetting the Universal Access settings as discussed above, the keyboard proved to be so flaky, that I took it back to Apple and exchanged it for a new one. The weakness seems to be in the bluetooth communication perhaps, with the keyboard accepting the new settings and then forgetting them somehow. So if you are a user reading this thread and you aren't getting any joy from the solution above, the solution is to take/send the keyboard back to Apple for a new one. The one I have now works just fine. It paired up much more quickly and it is typing this note without any issues. So far. I also picked up a wired keyboard in case I have to throw this one against the wall if it starts screwing up like the other one. Either way, I am covered.

Apple Aluminum Wired Keyboard: Special Keys Don't Work

The keyboard has function keys that are programmed to perform special operations. The Apple website explicitly states:
“The extended layout has a full complement of keys, including document navigation controls, a numeric keypad, and special function keys for Mac features such as brightness, volume, eject, play/pause, Exposé, and more.”
Unfortunately, two of these keys don’t work, even after a special software update is installed:
http://www.apple.com/support/downloads/keyboardsoftwareupdate11.html
The manual that comes with the keyboard provides instructions on how to program the keyboard, but those instructions either don’t work or are incorrect.
I've posted more about this and other keyboard issues here:
http://web.mac.com/resourcesforlife/journal/writings/Entries/2007/8/21Apple_Aluminum_WiredKeyboard.html

I am using a PowerMac Dual 2.5 GHz G5 system and had trouble with the F3 and F4 function keys. The various suggestions and instructions as provided on several of the discussion threads didn't work for me.
Here's what worked for me to resolve the problem:
1. Go here and download the Pacifist utility which helps in exploring installation packages:
http://www.versiontracker.com/dyn/moreinfo/macosx/12743
2. Go here and download the Apple OSX update for PowerPC:
http://www.apple.com/support/downloads/macosx10410comboupdateppc.html
OR... get the version for Intel found here:
http://www.apple.com/support/downloads/macosx10410comboupdatev11intel.html
3. Using the Pacifist utility, open the OSX Update dmg file you just downloaded. You will be able to navigate to /System/Library/Core Services. Click on Dock.app and click the install button. When it's uncompressed, it will ask if you would like to update or replace. Click replace. There is an option to repeat this response for all files. Complete the process and then exit the Pacifist utility program.
4. Go here and download the Apple Keyboard Software Update:
http://www.apple.com/downloads/macosx/apple/firmware_hardware/keyboardsoftwareup date11.html
5. Install the Keyboard update and all functions should automatically work.
If the above steps resolve the problem for you, please click on the "Solved" button above. Thanks.

Freaky Gigabit Ethernet Powerbook C T OPTION keys don't work

OSX 10.3.9 installed here...(1) to mount as a Firewire drive, holding the "t" key has no effect - goes to Finder (2) to boot from CD/DVD, holding the "c" key has no effect - goes to Finder, and (3) to try to run Apple Hardware Test before sending this unit to AppleCare, holding the "option" key has no effect, nor does the "commandoption+shiftdelete" key combination with a USB keyboard - goes to Finder. Going into AppleCare because certain keys don't work at all (Zero, hyphen, Delete, Return), but c, t, option, command, shift keys do. Any ideas? AppleCare demands that Apple Hardware Test be run on this unit...

Tom: You say you've tried Command-Option-Shift-Delete to boot to the AHT CD using a USB keyboard, without the desired result. Have you tried the same key combination using the built-in keyboard? I'm not sure whether you're supposed to be able to use a USB KB to control the startup process, and it may matter what USB keyboard you use.
Once you've booted to the HD with the USB keyboard connected, can you use it to type the characters that don't work on the built-in KB, including c, t, Option, Delete, zero, hyphen, Return and any others that seem to be broken on the PB's KB? If so, your built-in KB may be bad, or it may not be securely connected to the logic board. Have you disconnected and reconnected the KB cable (it's right under the KB)?

My mac seems to be frozen on an internet page. I cant force quit. I can't control+options+command+esc. I can't access my activity monitor. I can see my mouse moving but when I click on anything, it doesn't seem to engage or recognize it. Fix?

Thank you. There is a bigger issue. It is not the web page that is the problem. It is that I can see my mouse moving and can move it along the bottom toolbar and the options will highlight but I can't click on anything. I can see the apple icon to get to force quit but cant click on it.
I used your suggestion and force quit came up but I can't select the option to force quit... not even with my arrows and enter/return key. Any other thoughts?
Thank you.

[Solved]Keyboard layout screwed up and some keys don't work

After I reinstalled xorg-server 1.5.3-1 and installed xf86-input-evdev 2.0.1-1 and xf86-input-keyboard 1.3.1-1 some of my keys don't work and keyboard layout screwed up. I had finnish (fi) layout, but now it's "us". Arrows, insert- delete- home- end- pg up- pg down- print screen- scroll lock- pause- keys don't work. All characters behind Alt Gr + "" don't work either.
How to fix this?

I really need help because i've tried everything but I havent been able to make my keyboard work right, I have a MacbookPro fron the lates 2012 runing Mavericks.

Jekems,
when you say that “you’ve tried everything”, does everything include having made an appointment at an Apple store to have them diagnose the problem?

Next / Previous media keys don't work on 3rd Party Keyboard, Play/Pause does work. [MAC]

Hello!
So I am using a Logitech G710+ keyboard with my Mac (running 10.9) , and the media keys (Play/Pause, Stop, Next and Previous) work perfectly fine with iTunes, even in background.
Now, when I use Spotify, I usually quit iTunes (to stop conflicts), but only the Play/Pause key seems to work.
It does work in the background, which is good, but crucially the Next / Previous keys don't work at all.
Any ideas?

So I have the exact same issue as everyone else here. I have a Logitech K750 wireless keyboard running Yosemite on my MBP. I don't necissarily think this issue resides with Spotify, but instead with Logitech. If I use the media keys on my MBP I am capable of using Next/Previous even when Spotify is in the background. On the wireless keyboard only Play/Pause and the Volume buttons work. I think the issue is with the key mapping with the Logitech. Then again, I don't know how the code is written. Maybe Spotify missed an alternative key map for the media buttons. I didn't write the code.... The logitech forum is a ghost town for this issue though. Only post I found was 5 years old. EDIT: With further reasearch I DO believe the problem lies with Spotify. A tech for Logitech explained to me that Spotify wrote some "interesting" code for the keymap functionality for its Mac client. A quick Google search shows that it is not only Logitechs experiencing this issue. It would be great if we could get someone to look into this. It isn't critical, but it sure would be nice to get fixed.

New wireless keyboard & volume keys don't work

I just replaced my wireless keyboard because a few of the keys stopped working. Now the volume keys don't work on the new one. When I push them one of them brings up my widgets and the others minimize the screen. Any Ideas?

Put truly fresh batteries in the keyboard.
Un-pair and re-pair the keyboard with the computer.
Attempt the PRAM reset again.
If you do not get the 2 boot chimes then I would suggest you reset using a USB keyboard. Any USB keyboard will do. If you don't get the 2 chimes when using a USB keyboard then either you are not holding down the keys correctly / early enough or there is something wrong with the computer itself.
If you do get the 2 boot chimes you can then go back to the wireless keyboard and re-pair it.
Take a peak at this article. It is fairly exhaustive in troubleshooting suggestions for this type of issue: http://support.apple.com/kb/TS3048
Hope that helps.

Macbook pro 13inch,mid2010 qwertyu keys don't work after upgrade os x Yosemite

macbook pro 13inch,mid2010 qwertyu keys don't work after I upgrade os x 10.10 Yosemite. but it works on keyboard viewer. I'm not sure if it's hardware or software problem, how can I fix it?

Hello there, kipolo.
Great job using the Keyboard viewer to troubleshoot your issue so far. The following Knowledge Base article provides a great checklists of steps to pinpoint the issue a bit further:
One or more keys on the keyboard do not respond - Apple Support
Some keys don't work as expected
From the Apple menu, choose System Preferences.
From the View menu, choose Speech.
Click the Text to Speech tab.
If "Speak selected text when the key is pressed" is enabled, the key or key combination set to speak text cannot be used for other purposes or used to type text--click Set Key and change it to a less-commonly used key combination (try to use modifier keys such as Shift, Command, Option, and Control). Or, disable the "Speak selected text when the key is pressed" option.
Click the Accessibilty or Universal Access pane in System Preferences, then click the Keyboard tab.
Make sure that Slow Keys is turned off. With Slow Keys on, you need to press a key for a longer period of time for it to be recognized.
In the Accessibilty or Universal Access pane, click the Mouse tab, and make sure Mouse Keys is turned off. With Mouse Keys enabled, you cannot use the Numeric Keypad to enter numbers--instead the keypad moves the pointer (cursor). (There is an option to enable Mouse Keys with five presses of the Option key; you may want to turn that option off to avoid accidentally enabling it.) If Mouse Keys is enabled and you are using a keyboard with no numeric keypad or Num Lock function, see Unable to type while Mouse Keys is enabled in Mac OS X.
If the function keys on the top row of the keyboard are not working as expected, see Mac OS X: How to change the behavior of function keys.
If the issue persists, use Keyboard Viewer to help isolate the issue:
Click the Language & Text pane (Mac OS X v10.6) or International pane (Mac OS X v10.5.8 or earlier) in System Preferences.
Click the Input Sources tab (or Input Menu tab in Mac OS X 10.5.8 or earlier).
Click the Keyboard & Character Viewer "On" checkbox to select it (click the Keyboard Viewer "On" checkbox in Mac OS X 10.5.8 or earlier).
From the Input (flag) menu, choose Show Keyboard Viewer.
If the keyboard is connected and detected by OS X, the keys you type will highlight in the Keyboard Viewer window. Open TextEdit (or any text application), and try to type something using the keys that were previously not responding to see if they highlight in Keyboard Viewer.
Start from the Mac OS X Install Disc, choose Terminal from the Utilities menu and test the keys which were previously not working. If the keys work while started from the Install disc, then the keyboard itself is working correctly. Use How to troubleshoot a software issue to isolate the software issue that may be causing the keys to not respond.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Some of my keys don't work and now I can't login

Yesterday I accidentally spilled some liquid on my keyboard. A vey small amount and generally my computer is fine. I used q tips and paper towels to clean under the keys as best I could, turned it off, and put it in rice. unfortunately a few of my keys don't work--u i j k " : m < . The rest of the keyboard is fine and when I checked my laptop was still working fine. I"ll buy condensed air, and then pop off the keys and clean it if necessary. But I figured even if it didn't fix the problem I'm not buying a new laptop right now so I would just work around the missing keys. But I decided to restart my laptop and now I'm stuck on the login screen bc my password requires some of those keys. I was hoping to use my appleId to get in but I'm never prompted for it after entering wrong passwords. I was going to create a new user and bypass the password but the commands to do that also require those keys. I don't have access to my
installation discs.
Other options?

Some keys don't work in combination with Shift

Okay so I have the Pavilion Sleekbook 15-b011nr
Serial Number: [Personal Information Removed]
Product Number: C6N92UA
and today I noticed certain keys don't work in combination with the left Shift for example, Shift+S (both left and right), Shift+M, Shift+Z, Shift +X, Shift+C don't work, shift+F does work but gives me this FV. same with j it gives me JM instead. I installed an updated bios, ran a diagnostic test using F2 and under the compenant test for the keyboard it failed and gave me this
keyboard test failed
failure Id # U375BD-6m96P5-MFPX1F-G03B03
product id # C6N92Ua#aba
now while trying to type all this I found other letters now working as well as me not being able to input the semicolon with either shift key. frustrating since I got this laptop in June so it's still under warranty. Has anyone else encountered this problem and if so how do i fix mine? I'm pretty tech savvy so feel free to let me know, or is my only option is a replacement from HP?
Thanks!

Hi hzapata, I know that it work fine, after Load preset, but why You lost the default configs?
Is this my question to Smit.

What can I do if my function keys don't work correctly?

QuestionWhat can I do if my function keys don't work correctly?
AnswerFunction keys can mean a few different things. You might be having a problem with the F-keys near the top of your keyboard (F1, F2, etc.), the secondary functions of the F-keys (toggling the wireless or touchpad, for example), or special media keys on your laptop.
There are a few steps you can take to try to resolve these issues. Try the suggestions listed below in the order presented. If a step fixes the problem, you're done! If a step doesn't fix your problem, continue to the next step.
Understand the FN key
First, ensure you understand how to use the FN key. In most newer models, the special utilities of the F-keys are used when you press the F-keys. To use the F-keys, you need to hold FN first. In older models, this was reversed. pressing the F-keys activated the F-keys. The special utilities of the F-keys are used while holding FN. If you're having trouble using your F-keys, try both with and without the FN key.
Reinstall TVAP or Toshiba Flash Cards Utility
Some models may use the Toshiba Value Added Package or the Toshiba Flash Cards Utility. Check the support site to see if these utilities are available for your model. If you see either listed, download and install it. Some models don't use these utilities; it's okay if you don't see either of them.
