My wired keyboard has stopped working on my admin account on imac but works on another created account. Help?

Hi there.
I have been using my wired keyboard [not apple] for a while now and just yesterday it was unresponsive on my Admin User Account. You literally have to punch the keys for it to type a letter. I created another user account and it works absolutely fine. Please help?

Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

Yahoo business mail stopped being pushed to both of my iMacs, but working fine on iPhone.

I recently updated to 10.9.2. And I can see the messages on the server, but why can't I see them in mail??
I've tried deleting the account from my preferences, and adding it back in but still nothing. My normal yahoo mail still is working fine.
For business mail, I pay for POP forwarding.
Any help is greatly appreciated.

I'm SO frustrated with this Yahoo! email integration... I'm seeing the same issues as you:
1) PUSH email stops pushing
2) "Sent" email messages ("whoosh" sound implies all is well) via Yahoo! are not actually being sent.
This would be bad enough if when sending email the client actually told me there was a failure... but it turns out it's been a completely transparent problem. All appears well, but isn't.
The only solution I seem to have found is to delete the Yahoo mail account in the Settings/Mail area, and then re-add it through the Settings/Mail UI. After doing this I find that Push notifications and the ability to send email via Yahoo! mail returns.
.... The problem is that - based on previous experience - it won't be long before the client, or Yahoo (I have no idea where the problem really lies) will quietly stop functioning again.
I'm also a Yahoo! Plus email subscriber, if this has anything to do with the issue. Any non-plus users out there running into this issue?
Apple / Yahoo / AT&T... PLEASE fix this!

My iPhone 4 screen has stopped functioning normally, the screen is just blank but everything else is fine. Help!

I can receive calls and messages but cannot see them unless I do a screen shot then load it onto my computer. I have tried turning it off then on and also resetting it without success. It seems to be fully functioning apart from the screen being off. Can anyone help?

Hey NJF7,
Thanks for the question. After reviewing your post, it sounds like the screen is black. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.
iPhone: Hardware troubleshooting
Display has no backlight or dark screen
Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
Try turning iPhone off and then on again.
While connected to the iPhone charger, try to reset the iPhone.
If the low-battery screen appears, charge the iPhone.
Thanks for using Apple Support Communities.
Have a nice day,

The "enter" key on the numeric keypad of my external mac keyboard has stopped working. Help!

The "enter" key on the numeric keypad of my external mac keyboard has stopped working with my Macbook pro. If I plug the keyboard into any other computer, that entier key works fine. I'm using a standard Mac wired keyboard, & it's worked fine for 2 years now. Help!
This is the keyboard I am using: http://store.apple.com/us/product/MB110LL/B/apple-keyboard-with-numeric-keypad
Not sure what I might have accidentily done to disable the enter key. (The normal enter key works fine, just the one on the numeric keypad.)
Thank you for your help.

Hi there,
Do you have any resolution to this problem in the end? Because it happened to me an exact same thing.
Please share if you have found a solution to your problem. I also cannot think of what I did wrong to disable the Enter key.
Best Regards,
Jeffri

My Mac USB keyboard has stopped working

Hi,
I have a less than 6 month old fully loaded iMac 3.4 ghz i7. Overnight my USB (alphanumeric keyboard has stopped working. Had to dig out a wireless keyboard from another mac to login. The tried unplugging and moving the USB. ( All USB ports works and are powered up with other devices ) No change. Tried full system reset with power cord removed for 5 minutes, no change. Tried it all twice, no cahnge.
Typing this on wireless keyboard and hoping someone can confirm if Mac has pushed an update that forgets about the keyboard or if there is known issues with the usb wired keyboard that means they have suddenly got a life of less than 6 months?

Not any updates I know of, but if there were Software Update would offer them. Have you tried and SMC and PRAM reset - sometimes sorts out odd issues?

My keyboard has stopped working. How do I fix it?

Hello!
Today I got back to work after my summer vacation and for some reason my keyboard has stopped working.
I tried with my collegues keyboard but that didn't work either.
The keyboard works if I give my virtual machine in Parallels direct access to it, but not in OSX so it's probably not a hardware issue. (This is how I am writing this)
The caps-lock light works even when connected to osx. Mouse works perfectly in osx.
I am running 10.6.8 on a Mac Pro 2x2.8ghz xeon 12gb RAM.
Any ideas?
Thanks a bunch!
/Hannes

I upgraded to Mountainlion and the problem not only persisted, but also worsened.
Any button I pressed, it restarted.
I have removed a couple of apps I had installed, for example Double Command which I think might have been the culprit, and now the computer works fine again.
Big relief!

HT2452 my imac keyboard has stopped working? help!!!

my imac keyboard has stopped working??? help!!!!!

My keyboard just stopped working out of the clear. One minuet OK next it was dead. No little green light at all. New batteries did not help.
FIXED THE PROBLEM! I took a small piece of aluminum, made a little ball out of it and dropped it down the tube where the batteries go. Replaced the batteries I had just used......little green light comes on and the the keyboard functions like always.
My guess is after a few years the contacts oxidize a bit and don't make contact with the batteries on the bottom of the tube. Give it a try.

My keyboard has stopped working on my iMac I bought a new keyboard and still not working any ideas?

MY keyboard has stopped working on my iMac I bought a brand new one and the keys work but the volume buttons do not operate the volume I've changed it twice now and the same thing is still happening

What is the make & model number of the keyboard?
You could get a keyboard remapping program & map someother key to the volumn key.
There is a list of them in this thread.

The top row of my iPhone 3GS keyboard has stopped working.

The top row of my iPhone 3GS keyboard has stopped working. I've already done a soft reset, hard reset, and restored it to a new device. What else can I do?

When you are using other applications, or just on the home screen, does that area of the screen respond to touch?
Steps to resolve issue (I understand you have done what you have but it's always good to try again):
Clean the iPhone screen with the cleaning cloth that came in the box with the iPhone.
Do not wear gloves while using the touchscreen. Do not use the touchscreen with wet hands or immediately after applying hand lotion. Moisture affects touchscreen behavior in the same manner as it affects a trackpad.
If you have a protective plastic sheet or film on the touchscreen, try removing it because it may be preventing the touchscreen from working properly.
The current application may not be responding (frozen), press and hold the Home button below the screen for a least six seconds, until the application you were using quits.
If that doesn't work, turn the iPhone off and turn it on again. Press and hold the Sleep/Wake button on the top of the iPhone for few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
If that doesn't work, reset the iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
If the steps above don't resolve your issue, please schedule a service appointment with an Apple Retail Store for evaluation and replacement, if necessary, even if your iPhone is out of warranty. If an Apple Retail store is not an option, contact Apple to find out your best service option or see the iPhone Service FAQ.
Tip: If you are going to take your iPhone into a Apple Retail Store for evaluation, follow these steps to help the Mac Genius understand where your touch screen is experiencing unresponsiveness.
Open the basic calculator application to test all but the top row of the screen. Press each button on the calculator and verify activity.
To test the area at the top of the screen, rotate the iPhone to change to the scientific calculator and press all the buttons in the left two rows. (An original iPhone must have iPhone 2.0 software installed to access the scientific calculator feature.)
To test the touchscreen function at the top of the screen of an original iPhone without the iPhone 2.0 software, press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. If the slider does slide, press and hold the Sleep/Wake button until the Apple logo appears to turn iPhone on again.

My Apple Bluetooth keyboard has stopped working. The top row of keys works but the rest of the keys do not. I was carrying this in my computer bag without turning it off and that is when this started.

My apple bluetooth keyboard has stopped working. The top row of keys works and the iPad sees the bluetooth keyboard (the bluetooth icon is active) but the other keys do not work. For the past coupld of days I have carried my keyboard in my computerbag without turning it off and I am thinking I have done something to make the letter keys to stop working. Two days in a row I did turn on the music as I carried the computer bag into work so I know that some keys were being activated.

*UPDATE*
I have been able to use the Zoom function to zoom in and the keys on the top row no longer are in the non-responsive strip of area.

pamphellion,
if you plug in a USB keyboard, does it accept input that way?

My Macbook built-in keyboard has stopped responding, (even caps lock light does not come on). What can I do as cannot even login to computer?

My Macbook built-in keyboard has stopped responding, (even caps lock light does not come on). What can I do as cannot even login to computer?
There has been no spillage and it has not been dropped.

Do you have access to a USB wired Apple (or maybe even a PC) keyboard?
That may be used to help troubleshoot the internal keyboard and on startup
be able to access (or see if you can) the System, and attempt to see about
troubleshooting. See if it will start in SafeBoot, (shift key held down just after
startup tone, if it runs in safeboot, then login to see if you can read system
logs in Console) and another idea may be to attempt to start in Recovery &
then attempt to use OS X Utilities there to see if you can verify and then to
repair the hard disk drive, and do some checks on the hardware.

Was the computer an Apple official refurbished unit bought direct from Apple?
Did you get an extended warranty from Apple - if it were directly bought there?
Usually these are online purchases from Apple Store; other companies offer
repaired or restored used computers and call them 'refurbished' or they may
have bought actual refurbished from Apple stock; these may be resold on ebay
or via amazon, and may or may not have a residual warranty of some kind.
In some cases the keyboard may fail due to some connection on the logic board
not fitting correctly, or some other loose wire; however if the battery may have
swollen, that could contribute to issues with both trackpad and keyboard.
A visit to an authorized Apple service provider is recommended, or contact the
seller you bought yours from to ask if they may offer suggestions or perhaps a
discount on diagnostic + repair if there is no warranty on the product.

Good luck & happy computing!

My iPhone 5s has stopped playing music out of the speakers. It works when I plug in my headphones but other than that there's no sound. It just randomly happened so I'm not sure if I can fix it or if I need to bring my phone in

Mac Mail Version 6.0 (1486) has stopped recieving mesages regularly and the search doesn't work

Mac Mail Version 6.0 (1486) has stopped recieving mesages regularly and the search doesn't work.
Since installing Mountain Lion, Mail seems to be very unresponsive. I have mac mail running on an iMac (which works fine) and a 2012 MacbookPro which is the one having the issues with the Mail app. Both computers are running on Mountian Lion.
When I scroll up in Mail for instance, the frame rate drops to about 5 a second.
When I click on a message it doesn't display it in the preview pane. Which is very annoying!
But I can get around the issue by double clicking on a message and it opens up the message in a new window.
When I search for a message, nothing appears in the results. Even if Im searching for something that is defiently there, eg if I type in my name, you'd think some results would come up. But when I click on something else, the results dispaly for about half a second. Bizarre. Is anyone else having this problem?

what kind of error in browser you are seeing?
is search service application never starterd or its started but cannot crawl?
did you see the timer jobs related to search services and what's their status?
so what about the search results from site collection?
also make sure this service "SharePoint Search Host Controller Service" started on all servers in the farm.
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem. ****************************************************************************************** Thanks -WS MCITP(SharePoint 2010, 2013) Blog: http://wscheema.com/blog
In the browser I receive the following error:
The search service app is running, doesn't crawl:
Yes, I can see the timer jobs related to search services, some of them are Succeded, others are Scheduled.
The service SharePoint Search Host Controller Service is started in the first server of the farm, but not in the second
one. When I try to start it, I receive the following error:
Windows could not start the Sharepoint Search Host Controller Service on Local Computer. Error 1067: The process terminated unexpectedly.
