Apple wired keyboard stopped working after Mac Pro SMC Firmware Update 2.0

After the update, my MacPro will not deetect/accept the keyboard. My old keyboard (White plastic) works, my new (approx 6 months) aluminum wired keyboard don't. Keyboard tested on other Macs - no problem there.
Anybody know why/how to fix/have a solution?

SMC Reset and PRAM Reset are the conventional ways to deal with such problems.

Apple wired keyboard stops working after iTunes sync

I have an imac running snow leopard. When I sync old ipad, iphone 3gs or iphone 4, the wired keyboard stops working. The only solution seems to be to turn the IMac off and turn on again. Have tried resetting permissions with no success. Any ideas?

Try resetting the NVRAM

Try another BK. Maybe a KB problem.
Try booting to Recovery and see if it works OK. Maybe a software problem with Yosemite

"The SMC Firmware Update adjusts fan behavior in Mac Pro. The updater application will be installed in the /Applications/Utilities folder and will launch automatically. Please follow the instructions in the updater application to complete the process."
-----THIS IS WHAT HAPPEND TO ME----I try this morning to install and this is what I got:

Are you booting from RAID? even though it warns that you can't be booting from RAID, some people still run the update.
Any problem with your system?
While it only says that you need to quit any and all open programs, sometimes it helps to reboot (and boot into Safe Mode) just to begin the process.
When there was an SMC Firmware update before (last fall) some people also had trouble.
We aren't mind readers, and to say it failed doesn't give those of us reading this (and non of us are Apple tech support) a lot to go on.
+Please follow the instructions in the updater application to complete the process.+
+To update the SMC firmware on your Mac Pro:+
+Your computer’s power cord must be connected and plugged into a working power source.+

Mac Pro SMC Firmware Update 1.1 keeps repeating

Recently I had my MacPro motherboard replaced by an Authorized Repair Center, and for the most part, everything has been working great since. That said, as I've been performing my regular software updates, I've noticed that the "Mac Pro SMC Firmware Update 1.1" keeps appearing as new update. I've installed this update multiple times now (or it seemed as though I did), but it keeps appearing with each new update.
Is there some way I can complete the update? Is it possible that there is some serial number conflict between my old/new motherboard that is preventing this? Do I need to return my machine to the repair center?
Thanks for any help.

Did you actually run the update from your Utilities folder (where I believe it ends up)? You'll go through a process of rebooting and hearing the long tone / seeing grey screen and progress bar. Until it's actually run properly, you'll keep seeing reminders.

Apple (wired) keyboard stopped working

Hi everyone,
I bought a 2.8 GHz Quad-Core Intel Xeon "Nehalem" processor Mac Pro (model MC560LL/A) in April, 2011.
1 year and one month later (after the warranty expired, natch), the apple wired keyboard (MB110LL/B) that came with the computer stopped working. No stuck keys or repeating characters, just stopped working altogether.
I didn't drop the keyboard, or spill anything on it. As a matter of fact, I kept the keyboard clean with a cover. I tried the keyboard in every USB port, no dice. I've rebuilt permissions and zapped the PRAM, still no dice. I'm stuck using the clickety-clackety black keyboard from my G4.
Has anyone else had this problem?
Since it's been one month (and 2 weeks) out of warranty, should I still try to get Apple to replace it?
Thanks in advance for any help.
p.s.- OS 10.6.8

OK, it looks like Christmas came early.
I called Apple (and spoke to a WONDERFUL service agent named Hannah), and she agreed to send me a replacement keyboard at no charge, even though the warranty on my non-working keyboard expired 38 days prior.
I was wanting to replace the wired keyboard that I have with another wired keyboard, because of the numeric pad. Unfortunately, Hannah informed me that Apple no longer sells the wired ones and that I would be getting a wireless keyboard as replacement. Bummer.
I ended up buying a new wired one, because I really need the numeric pad. I'll have to send the wireless one back. I feel awful that the good will was wasted. At least I left a glowing review for her and suggested that she get a raise!

After upgrading to 10.8.3 my Apple USB keyboard stops working after about 3 hours

Mac Pro 3,1
OS X 10.8.3 Server
32GB RAM
Apple USB Keyboard works fine after reboot (typing on it now), stops responding after about 3 hours.
I see nothing in Console that looks like the culprit. Here is everything around the last time it happened - between 11:28 and 11:30 they keyboard just stopped working. Unplugging and re-plugging doesn't bring it back. Changing USB ports doesn't bring it back. Rebooting is the only thing that seems to work. Bluetooth keyboard works before and after.

Everything worked fine in 10.8.2.

Hey Doug,
Thanks for your post, and welcome to the Apple Support Communities.
I understand that your keyboard backlight is not working upon startup, the following may resolve your issue:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
After performing normal troubleshooting, these symptoms may indicate that an SMC reset may be necessary:
Lights
The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
You may also want to reset your computer's PRAM:

Note: Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.

IPod Nano stops working after 1.0.2 firmware update

I just updated the firmware of my ipod nano last night to 1.0.2. I was using thru out the day when it suddenly stops playing the next music in my playlist. My ipod shows the play icon but there is no sound and the play track is not moving. Tried to play a different music and videos but the same problem occurs. Tried to reset is several times but doesn't fix the problem will try to reset the firmware later when I get home.

Just got the nano 3rd gen yesterday. Already had a Nano 1st gen. Running Itunes 7.x on windows 2000 os at work (1st gen nano used there). Needed new Nano in a hurry, so went to RShack and bought one. Ran home....Itunes says wont work with Nano 3rd gen. Went to download upgrade for Itunes, and find out the upgrade won't run unless running windows XP or VISTA.... Borrrowed a laptop with XP OS and got latest Itunes. Happy...happy...joy...joy, now I can get Itunes and new Nano to work together. Now gotta get music off old Nano and into new Nano usiing borrowed laptop. (Found a program on net called 'SimpleCenter' to do this.) Xferred music from old Nano to Itunes on laptop, then transferred entire library to new Nano. (Was out of reach of wireless network while doing this, so was unable to 'UPDATE NANO' when prompted by Itunes.)
Sooo...
Took laptop over to its owners home (and wirless network) and Updated the firmware to 1.0.2. When supposedly complete, the new Nano starts to Reset continuously (Apple Logo....Menu Screen......Apple Logo.....Menu Screen....Apple Logo etc. etc.) Oh 'darn' ........
So frustrating.... Disconnected new Nano from laptop during the couple seconds the main menu was showing.
For grins went to play the solitaire game that comes with new Nano, but comes up with error message saying it (the game) won't load. (Worked fine earlier, before the 'upgrade')
Oh Mannnn..... I find that there a 'ton' of other 3rd gen Nano usere having same problem with firmware upgrade 1.0.2.
I will wait for some response from Apple on this issue for a few weeks before I take the device back to dealer. I expect that this problem will be resolved by Apple in quick order in the form of a new firmware upgrade (or something similar). I really don't want to hassle the dealer at this time, and can live with the old Nano at least until the end of November, when I will be needing both Nanos for a special event.

Mac Pro SMC Firmware Update Won't Install (Mac Pro 2007)

This keeps popping up in Software Update, even though I've 'Installed' it.
I restart, progress bar goes to 100%, fans spin up...reboot. However, evry time Software Update loads...there it is agian. I've checked the Firmware/Boot ROM number, and it's not what it should be (is still the previous rev.)
I've done this 4 times now...
Is it even worth bothering with?

Why did AME stop working after the last Windows 7 update

AME suddenly stopped working after the last Windows 7 update. After the initial splash screen, I get a message saying that AME is not working and the program will be closed. Then I get the windows message that it is searching for a solution, then nothing. I am using the Production CS6. This happens whether I try to start AME directly, or queuing through Premiere Pro. I have tried reinstalling the entire package and have implemented all available updates from Adobe. I have no clue why this happened, but AME is crucial to my workflow.

Try to delete the following folders and then launch AME:
%AppData%\Adobe\Adobe Media Encoder
%AppData%\Adobe\Common
Make sure to first make a backup of those folders.

Don't know what to do or who to ask??? GPS stopped working after 4.4.2 Kitkat update.

Don't know what to do or who to ask??? GPS stopped working after 4.4.2 Kitkat update.
I have been on the phone multiple times with Verizon, visited multiple stores and still getting different answers with every different person I talk to...
Since the 4.4.2 update, my phone and my wife's phone (14 or 15 month old SIII's) that worked perfect a couple weeks ago no longer know where they are 95% percent of the time... Location cannot be found and GPS satellites cannot be seen (sometimes after searching for 10 - 20 minutes they will lock on).
And it's not just Google maps, it is all apps that need location (ie. gps status and toolbox, weather channel, etc...)
Google maps has us in the right location 50% of the time but i think that has more to do with 4g and wifi (although i always know the weather and traffic conditions in the next town over now).
Navigation will set up fine in Google maps until you actual move the car. Then it updates location every couple minutes, but usually a couple streets over from where I actually am. Maybe 1 out of every four or five times I try it, it will start working about 15 minutes after I started it (then work flawlessly, so it can actually work sometimes). But if you end the process and start over to see if it really "works", back to square one with it not knowing its location all over again...
I obviously did all the normal trouble shooting fixes with the battery and sim card removals and even did a "recommended factory data reset" on my phone with no luck. After this didn't work I stopped by another verizon store yesterday that has "tech services" that I was told could run some sort of diagnostics on my phone. After I showed the tech all the screen shots i have taken of what was happening while driving, he said it is a software problem and a very common one at that.
I was told I should either buy new phones or switch to the edge program where i can get a new phones. These don't seem like very fair solutions to me considering before the 4.4.2 update our phones worked perfect and they are both in almost perfect condition after 14 or 15 months...
Will there be a fix to this??? Is it a Samsung problem??? Should I be contacting them???

If it is 3GS, you can update it to iOS 5 and it will work.

MacBook Pro SMC Firmware Update 1.3 update freezes mouse pointer

After installing the update released today 5/28 (MacBook Pro SMC Firmware Update 1.3) my mouse pointer stalls, freezes on occasion. Very annoying. Anyone seeing the same. Fixes ... ?

After applying the SMC Firmware update a few days ago, my keyboard and trackpad were acting erratic (freezing, hanging). It was immediately after the update and I had not had any problems with it before.
I have also had random crashes, inability to use the keyboard/trackpad ever since.
Today my keyboard and trackpad are completely unusable, external mouse works fine.
I will take it to an Apple store tomorrow, hopefully my firmware can be reverted.
Sounds like a lot of other people are having problems with this update. http://discussions.apple.com/thread.jspa?messageID=9549034&tstart=0#9549034

Apple usb wired keyboard not working for MBP pro w/ 0 for stop on numeric k

Just got logic 8 and noticing that it does load up quicker with the new os update.
I'm going through the first getting started manual and I have a apple usb keyboard attached to my mac book pro.
When I press 0 on the numeric keypad it doesn't stop the sequencer it just plays this soft like error sound or something. space bar works for stop however.
Am I in the correct mode or what not? when I press 1, 3, 6 the views change, if there are different modes for the numeric keypad.
I need to get that 0 key working for stop as it says in the first getting started manual on page 18 under "To start and stop playback:"
my setup

The zero button doesn't work for screensets - there are no screensets with a zero in (ie, it goes from 9 to 11, there is no 10).
If you want your zero key to do something, use the key commands window to assign it to whatever you like.

TS3048 Number pad on extended keyboard stopped working after updating to OSX 10.9.1. Testing keyboard on old system still works perfectly.

Expanded keyboard stopped working correctly after updating my system from OSX 10.8.6 to OSX 10.9.1 and now 10.9.2. The keypad numbers do not work although the numbers along the top of the keyboard work fine. Moving the keyboard back to computer still using 10.8.6 and it works fine.
