Bluetooth keyboard not working after 10.7.2 update

Just got around to installing the 10.7.2 update this morning, and afterwards could not connect my Apple bluetooth keyboard. I've also had some difficulty with my Apple mightymouse (yes, it's old, but I love it). I tried restarting with the keyboard and mouse off and trying to re-connect using the Bluetooth preferences, both SMC reset and PRAM reset, repairing disk permissions, and all of the suggestions on this thread: https://discussions.apple.com/message/16377827#16377827
So far nothing has worked. My mouse began working again after the initial restart with both bluetooth devices off, but the keyboard isn't being detected in either the Keyboard setup or the Bluetooth setup assistance. The keyboard, however, was detected by my iPad, and was working with this computer before the update. I've made sure that the bluetooth on my iPad is off so as not to confuse it, and it's still not working.

Well, I found a solution. After removing the bluetooth preferences as directed in this article (which didn't help me, but might somoeone else): http://ismashphone.com/2011/08/how-to-fix-bluetooth-pairing-in-mac-os-x-lion-iss ues.html
There was a software update that fixed this. Thank goodness. So if like me you're just getting around to doing the update, after the big 10.7.2 one, check software update again. I assumed it would be all rolled in to the same update, but that was not the case.

  • Bluetooth keyboard not working after sleep *windows8* FIX

    Its pretty simple actually.  It might not work for you, but let me know if it does.  Untill bootcamp drivers are updated, I found that disabling the Bluetooth Network adater under Networking And Sharing in the control panel will allow my Keyboard to function again after waking up.  If you find that your keyboard is still paired, but not responding when your Windows 8 install wakes up after sleep, this might fix the problem for now. 
    If you have a notebook, I read on another forum that if you enable Bluetooth Collaboration under the device settings in Device Manager, you can fix this issue also.  Google for it if your interested. 

    I've noticed on mine that if it is coming out of Ssafe Sleep (you can see the progress bar at the bottom of the screen if it is) then the keyboard does take a bit to active.
    This may not be your problem however just be sure you've been patient enough after waking.

  • Bluetooth Keyboard not working on iMac after upgrading to 10.10.3

    I upgraded to Yosemite 10.10.3 and my bluetooth keyboard stopped working after a while. iMac (Late 2012) sees it but don't want to pair. You can see it on screenshot (never mind Russian interface).
    I tried everything:
    a) resetting PRAM
    b) resetting SMC
    c) turning bluetooth on/off
    d) changing assumes in keyboard
    etc, etc...
    Nothing helps. Can somebody help?

    HI Michelle
    i have the same problem Also using an iMac21 inch late 2012. Has been working perfectly until 10.10.3. Now when the iMac wakes from sleep neither the mouse or keyboard are connected. The only recourse is to force a hard restart with the power button.
    i have tried all your above items and also to no avail. I have set sleep to wait indefinitely & that has resolved my issue. Albeit with an increase in energy use.
    I Would be grateful if anybody had some tips on how to resolve this situation.
    thanks

    Hi and welcome to the forum!
    Does the keyboard work fine inside the BIOS?
    Also try booting from LiveCD of Ubuntu, if issue remains then the keyboard is faulty.
    Keep us informed.

  • Bluetooth keyboard not working.....power light flashes

    Hi everyone,
    My iMac bluetooth keyboard stopped working on the weekend. The green light adjacent the keyboard's power switch started flashing rather than staying on. I replaced the batteries but that didn't seem to help. My bluetooth mouse is working fine. Has this happened to anyone?
    Cheers,
    Jeremy

    Yes it has happened to me. Just added it to my long list of repairs. Do you have Applecare? In July, I had to have the logic board replaced. After the tech installed it, wham!!! Power supply was gone. Then it was the hard drive 3 weeks ago, after a few hundred bucks to get everything backed up then Lo-and-behold the keyboard over the last weekend. I called apple and then ran thru a few things. Like have you checked the batteries, try toggleing the on switch, unplug and replug it back in. After 10 minutes, the rep said "I can send you a new one." So if you do have Apple care, call and get a new keyboard. I just hope it is the keyboard and not the bluetooth.

  • USB Keyboard not working after running Monolingual

    Okay, I'm not a Mac person and should have known that I was going to mess up my mother's iMac, but here it is -
    In an attempt to improve the mac's performance I performed all of the actions described in the following article: 11 Ways to Optimize your Mac's Performance     ( http://lowendmac.com/eubanks/07/0312.html ). Basically, I cleaned up files and 'other' system preferences. Things seemed to be fine and the computer did run much better. However, after running Monolingual and deleting what I understood to be 'unnecessary' PowerPC files the standard USB keyboard is no longer working.
    I've tried to search for various remedies, but have come to a dead end. So I'm left with reinstalling the Snow Leopard OS (I think it is 10.6.8?) BUT I can't because it is asking to input the account password (which I know) to make the change and I can't figure how to do that when the keyboard not working.
    Any help would be great!
    *feeling like a bone head*

    How are you trying to reinstall Snow Leopard? If you're booting from the Snow Leopard or iMac Install DVD that came with the system then that should eliminate any of the issues you may or may not have caused when you deleted did the clean up work on your mom's system.
    I suggest trying the following:
    0) Verify that the caps lock key is off. It can make inputting passwords difficult if you don't realize it is ON.
    1) Reset the PRAM by restarting the system then quickly press the command-option-P-R keys before the gray screen appears. Wait until you hear the computer restarts two times as indicated by the startup chime. For more info refer to http://support.apple.com/kb/ht1379.
    2) If the issue persists after the PRAM reset then boot from the Snow Leopard or iMac Install DVD, whichever you have. Once you see the menu asking you to choose a language try using the arrow keys on the keyboard to move the language choice selection. If the arrow keys are working at this point it indicates your keyboard is at least partially functional. Go ahead and select the language then proceed to step 3.
    3) Once the next screen appears move the cursor up to the menu bar area and pull down the Utilities menu. Select the 'Terminal' application. Once the Terminal application launches try typing the various keys on the keyboard and check to see if the correct characters are displayed. Please let us know if you detect any errors. If there are no errors then you should be able to quit the Terminal application and proceed with reintstalling the OS.

    Just my 1.46¢
    You're right, problem wasn't actually solved. In fact, yesterday I upgraded the whole system again and the same problem showed up, but I got it fixed.
    Same scenario: after a boot (shorter than usual), what I had was a tty, but I noticed something that I hadn't noticed the last time: the prompt said "Arch Linux 3.11.[?]".
    The kernel version was supposed to be 3.12.[?] so I started investigating and after several attempts, this is how I got the system working again:
    1. Chrooted into the system
    2. Wiped /boot
    3. Re-installed grub
    4. Re-installed linux kernel
    5. Re-created grub.cfg
    6. ???
    7. Profit
    I'm pretty sure that what originated the problem wasn't a "kernel issue" as I pointed out in my previous post, but it was an incorrect installation of grub: in fact, the grub prompt never showed up before yesterday, the system used to boot straight, ignoring the 5 seconds timeout.

  • Drobo not working after 10.5.8 update

    My drobo stopped working after 10.5.8 update. Now I lost all my data on the drobo. this doesn't make me happy.

    'We are using the USB interface (as opposed to firewire) because we want to share the drive across the network - it's not always about speed.'
    This makes absolutely no sense to me.. but maybe I am wrong : Because firewire is much more reliable than USB and manages to keep highest transfer rates (without jumping up and down as USB would do as soon as I/Os go up...) Especially on a Mac ! (only for the latency I am not too sure, but I guess it is similar on fw and USB.. just increase the caching if you stream hd movies on the network...
    From my experience, sharing a USB drive on the network is probably much worse.. you can find example on the web.. (Orb, Plex and else will start drop frames when connecting to a USB shared drive.)
    I currently use my drobo plugged to my Mini with a fw800 to 400 cable,4*1.5tb hdds, I also share it on the network with gigabit ethernet, and get much better performances than any usb shared drive.
    Sorry I do not have any precize measurement, but I can upload or download a 6tb file in about 10minutes over gigabit ethernet, and I guess the bottleneck is now the Drobo controller...
    The protocol you use may have an impact as well (afp, smb,...) but whatever you use, I suppose Firewire will be faster.
    As a general advice, do not update or upgrade anything in general before you have a backup of your data, this is true for any storage system, Drobo or not.
    Oh, and Data redundancy on a raid is not a backup of course.

  • External monitor Syncmaster 2494SW not working after 10.6.7 update

    External monitor Samsung Syncmaster 2494  SW stopped working after 10.6.7 update on 2011 MacBook Pro. I'm using miniDP-DVI adapter. The monitor shown correctly in Display Properties with right modes and name. MackBook recognizes connection but the monitor goes to PowerSave mode (LED indicator blinks).
    Safemode boot, SMC reset, PRAM reset did not help.
    Exactly the same setup works perfectly under 10.6.6.

    HERE IS THE EASY FIX SOLUTION FOR THIS PROBLEM GUYS:
    I have an 15inch MacBook Pro that I've just installed Snow Leopard 10.6.3 on.
    Prior to this install, I've had it hooked up to my Samsung SyncMaster 2243 via an Apple MDP/VGA adapter and a third party VGA cable. It has been flashing on and off a black screen every now and then for the past 2 years and I googled that it was just a crappy communication between the MBP and the Samsung... but now since installing 10.6.3, the Samsung display just flashes the desktop for a second then turns black for good - occationally flashing analogue/digtal prompt display. Tried everything for hours. Nothing worked, thought I was gonna have to buy a new all Apple VGA lead then came across Michael's above solution. Tried it and it worked IMMEDIATLY!!! And the monitor doesn't flash black anymore AT ALL!! Whoo-hoo!! Thanks heaps.
    WHAT TO DO TO FIX:
    Go to => System Preferences  => Energy Saver => change graphic settings to Higher Performace.
    Cheers!!
