Lion Recovery - Mouse & Keyboard do not respond

I recently updated to Lion Server 10.7.4 on my MacMini 5,3 (Mid 2011). Now whenever I use Lion Recovery (Ctrl-R at boot), the keyboard does not function. The mouse cursor moves around, but clicking the mouse button has no effect. I am unable to run any of the utilities (recovery, disk utility, etc.) and I am forced to press the power button to turn off the computer.
Is anyone else having these issues? I had no problems before 10.7.4.

Wireless keyboards are recognized at varying points in system boot.
Keep a cheap wired keyboard and wired mouse for times when you NEED the devices recognized ... my opinion.

    First check your settings.  If all is as it should be, reset the PRAM.

  • Mouse jumping or not responding

    I have the original bluetooth mouse that came with my iMac, this was pre mighty mouse. The problem I'm having is that the mouse sometimes does not respond or the cursor jumps around when I'm using it. It has never done this before but started about 2 or 3 weeks ago. I guess I've had this machine for 4 years...so maybe the mouse is finally giving out on me? What do you think?

    Hi Barry (great name!):
    It probably is the mouse. If you have an opportunity to try it on another Apple, I would do so.
    You might also reset the PRAM and then restart:

    You could also trash a preference file (com.apple.bluetooth.plist) and restart.
    If none of that help, I would think the mouse is failing.

  • The third row on my MacBook Pro keyboard is not responding is there anything I can do

    The third row on my MacBook Pro keyboard is not responding is there anything I can do

    You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

  • Bluetooth keyboard, mouse and trackpad not responding after 10.8.5 update

    I updated to 10.8.5 on my iMac this morning.  The update has killed my trackpad, mouse and (presumably) keyboard as well.
    OS X will boot to the log on screen but the mouse pointer is stuck in the top left of the screen.  Trying keyboard, mouse or trackpad obtains no results.  Switching the bluetooth devices off and on, will obtain a connection lost and connected on the screen but still the pointer will not respond.
    I have tried hard booting to computer twice now and it has not resolved this.  As of right now I am totally unable to use my iMac due to the software update as I have no wired keyboards or mice.
    Help!

    Maybe they will work in the Safe Mode.Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. 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. 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 uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.

  • I am using a USB keyboard and everytime I wake the iMac from sleep the keyboard will not respond unless I unplug and replug the keyboard. I am using a mid-2010 iMac with OSX 10.6. Any help would be appreciated.

    I am currently using a USB keyboard (PC Model) and everytime I wake the computer from sleep the keyboard no longer responds unless I unplug and replug it. The USB mouse I am using works fine with no issues and I have already gone through the prompt to identify the keyboard in the settings. If anyone know of a setting I can use to permenantly enable the keyboard so I no longer have to unplug and replug it that would be appreciated.
    Thank you.

    Your 2010 MBP would be able to handle Yosemite, but I would strongly suggest that you get the current problem sorted out before trying to upgrade to Yosemite. I'd also recommend another backup that isn't created by Time Machine if you are thinking of upgrading. SuperDuper and CarbonCopyCloner can make bootable clones of hard drives. If you clone your existing system to a fresh external drive, you would be able to boot from that drive and recover quickly in the event that your Yosemite upgrade didn't work out. Time Machine backups are not 100% reliable.
    It's possible that, if your internal HD is the one that shipped with your MBP in 2010, it may be failing. If it keeps needing repairs, that is probably a sign that it is approaching the end of its useful life.
    Have you run Disk Utility's Repair tool on the external drive as well?
    I mentioned the hub because some people have reported here that attaching their USB 3 drives through a USB 2 hub solved some disconnection problems. A good-quality powered USB 2 hub won't cost much.
    My most recent brush with random disconnections involved a nice new OWC drive enclosure. I used the cable that came with the drive, but the drive kept disconnecting. Using a different cable solved the problem. You wouldn't expect that what appeared to be a high quality cable would be a problem straight out of the box, but it was.

  • System wide keyboard commands not responding

    My mac stops responding to system wide keyboard commands such as the Dashboard, Expose and Spotlight shortcuts. It also does not respond to Command-Tab to switch between applications. Hitting the keys for any of these leads to no response whatsoever.
    I have run into this problem several times over the last few months, and the only solution I have found is to restart the computer. Initially, it appeared to be related to the ScreenSaver process crashing. I could look in the System Monitor and see that this process had gone red, when I forced the process to quit, the keyboard commands were restored. More recently, though, this has not been the case, and I have had to restart.
    Any guesses what could cause this or suggestions on how to diagnose it? Thanks for any help.

    I'll answer in reverse.
    When I've experienced the problem, I have tried other (older style) keyboards, and that did not resolve the problem.
    I've never tried creating another user account.
    I'll try disabling the screen saver, but part of the problem is that this issue is sufficiently intermittent that it take a while to determine if this has a benefit. I was hoping to find some more systematic way to diagnose what has been happening. Any suggestions along these lines?
    Thanks for your help and interest.

  • Apple Blue Tooth Mouse & Keyboard will not Wake Mac Pro while in Vista

    I am running Vista Ultimate via Boot Camp OSX Leopard. I have a MAC Pro with apple blue tooth mouse and keyboard.
    When the computer sleeps while in Vista, neither the mouse or keyboard will wake the computer. The only way to wake the computer while in Vista is to press the power button the MAC Pro.
    After I wake the computer via the power button, the keyboard is unresponsive for about 2 minutes. Turning the power on and off on the keyboard does not speed up the process. The same thing happens intermittently when rebooting into Vista.
    AppleCare says it's a Vista problem. Microsoft tech support says it's an Apple driver problem. Nice.
    The keyboard and mouse do wake the computer when in Leopard.

    Were you ever able to find a resolution to this issue? I am seeing the same perplexing grayed out box in device manager. In my case I'm using a MS Bluetooth keyboard and mouse and my machine is a Mini.
    For anyone else who might happen upon this post, the exact click sequence is:
    Device Manager -> Bluetooth Radios -> Apple Built-in Bluetooth -> Power Management

  • CF card + card reader + iMac + OSX Lion = Dead mouse + keyboard

    When I insert a CF card to my card reader which connects to iMac 2011 running OSX Lion, both my magic mouse and wireless keyboard stop working. I have to do a force shut down to resolve. What would be the root cause and any permanent fix?

    Try doing a both SMC and PRAM resets, you should try each 2-3 times if they don't work the first time. If that doesn't work then restart in Safe Mode which will clear some caches, it's possible one has become corrupt.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Wireless Mighty Mouse right click not responding

    I was happily using Final cut Pro but noticed that the right click on the mighty mouse wasn't working. I checked my settings of the mouse and confirmed that 'secondary button' was selected, but no right click was picked up in any application.
    Rebooted Mac with no effect. Switched right button to 'Expose' but that wouldn't work either.
    Solution: Took batteries out of mouse and reinserted. All now resolved.

    Have you shut down (powered off) the Mac and restarted since this problem occurred? Have you turned OFF Bluetooth and turned it back ON? Have you checked the strength of the two batteries in the mouse?
    The buttons not working does not sound like a typical cleaning or hardware issue (although the scroll ball not scrolling is probably a cleaning issue). It may be a software problem.
    First, go to System Preferences +Keyboard & Mouse+ pane Mouse tab, and make some changes to the settings of the buttons that do not work. Change them any to a different setting. See if each change takes effect. If it does, change it back to the way it was before. This will rewrite the preference settings, and hopefully get those buttons working again.
    I would also do the usual general trouble-shooting actions. Run Disk Utility and use the +Repair Disk Permissions+ routine. Then restart using the reset PRAM command.

  • Keyboard Backlight not responding at startup or after awakening.

    The keyboard backlight on my MacBook Pro does not work upon startup or upon awakening. Even when I cover both of the speakers it fails to turn on. I have to press F10 and then it lights up but, it lights to the first bar. Not where I had it before it went to sleep. Is an body else having this problem?

    Make sure the keyboard is set to automatically illuminate in the Keyboard & Mouse System Preference.

  • My USB Apple Aluminum Keyboard is not responding during Bootcamp Install!

    I am going crazy, I have had the worst experience with this Bootcamp install which is supposed to be so easy, resulting in Apple replacing my MAC pro, and I still can't get it to work on the new machine.
    My first problem was using a Windows XP Pro disk, which resulted in my continually getting a black screen saying "no bootable device, press any key to restart." I ran into this problem because I overlooked the instructions to use a USB keyboard and mouse, I was using the wireless. This process resulted in Apple replaceing my MAC Pro because some how my start-up files dissappered and the MAC geniuses couldn't even reformat my drive.
    After recieving the new MAC Pro, I tried to run the Boot Camp install, using the same Windows XP Pro Disk, but now with a wired USB Apple Aluminum Keyboard and USB might mouse. I was still running into the same problem, after windows finished the Install and restarted a black screen would appear "no bootable device..." After searching many forums I found that for some reason Windows XP Professional disk skip the step where you would format the drive you partioned for Windows. I found in a forum a way to address this problem by going in DOS and entering commands to tell Windows to format the drive. I was not comfortable doing this, so I thought I would take an easyier route and get a Windows XP Home edition.
    All windows versions I used were OEM, but they were all full installs (fancy hologram CD) w/Service Pack to and certificates of authenticity**
    I thought great now everything should go smoothly, I have Windows XP Home Edition w/SP2, I have a USB wired apple aluminum keyboard, and I have a USB wired might mouse. This has not been the case.
    After I complete the Bootcamp process on my Leopard operating system and Windows XP completes loading all the file prior to begin the Install, the Windows XP Installation asks to press "Enter" to begin Install. This is the point now I can't get past, because I get no response from my keyboard. I tried every USB port on my CPU and still no response when I reach this step in the Windows Installation. I am becoming very disgruntle with Apple because the AppleCare, which I pay for, and the MAC genius will not help me with this problem because it is during the Windows Install. Please help before I flip out.

    That worked after using a generic DELL PC keyboard no extra keys. Apple hustled me into buying a wired keyboard, because I had only ordered the wireless keyboard.
    Thanks

  • Keyboard Shortcuts not responding in PScc

    So every once in a while keyboard shortcuts just wont respond at all. I think I've narrowed it down to it happening when I try to copy text from an external source, then paste it into a text layer.
    The shortcut will switch to the correct tool in the toolbar, but the tool won't actually work. the only thing I've found that works is to save and quit photoshop and then reopen it, but that is kind of a hassle.
    Anybody know how to fix this bug or if I am copying the text wrong?
    I'm using PS CC v14.1.2 x64 on mac.
