Hi All,
Not sure if this has been posted by anyone else, but since updating to 10.4.9 on my 17" G4 iMac and and 17" G5 iMac - I have had ongoing problems with bluetooth on each computer where the keyboard continually drops out with "Connection Lost" error (Usually once a minute when I am using the keyboard). (Keyboard problem on the G4 iMac)
And on the G5 iMac, I am having exactly the same problem but with the mouse dropping out every minute or so.

I've reset the PRAM on both computers, but still the same problem.

Any help hugely appreciated.

iMac, Mac OS X (10.4.9)

    My mighty mouse is giving me headaches as well. It loses connection and whenever I reconnect, right after it, it will nicely give me a kernel panic. Instead of wasting their time on iPhone...

    Hello. I am also having a similar problem with both my wireless keyboard and not-mighty mouse (true, this is happening since I updated to 10.4.9). Coupled with that, I cannot access the BT control panel. If I try, the Mac hangs. This happens in all accounts and even if I create a brand new one.

    I'd like to uninstall and reinstall the BT control panel but I have no idea how (I searched the tech support area and I found no help there). So far I dumped the BT prefs as well as the Cache files related to BT but that does nothing either.


    Thank you.

    Similar problem. I will sporadically have a connection with my wireless mighty mouse but this connection usually lasts less than 3 minutes. This has been a constant issue since early last week when I installed the OS update.

    Also, my internet connection has noticeably slowed on my macbook. Pages on the Apple website take 30 seconds to 1 minute to load up.

    Any insights would be appreciated.

    Thank god i've found this i thought it was me, Since 10.4.9 Bluetooth With Keyboard has become a nightmare. I'm having to turn off and on yues I've changed Batteries. Is Apple aware of this problem?

    Ditto. My apple wireless keyboard on my IMac G4 suddenly stopped being recognized this morning.

    There is a little app called Maintenance that can be downloaded from the Apple Downloads section of the Apple site. I ran all the scripts and then restarted and the keyboard paired after some hemming and hawing.

    I suspected it was a software glitch on the desktop because the keyboard paired perfectly with my laptop.

    Hello William. Thanks for the tip. Can you please be a bit more precise regarding the location of the app you wrote about? I went to Apple/support/downloads and the app is not listed -that I could see- nor the search button helped find it ... Thanks in advance. A.C.

    Did you get a fix to this problem? My Keyboard has been doing the same thing since day one, my MAC mini came with 10.4.9.
    The keyboard frequently loses connection but the mouse works perfectly.
  • Andres Cathalifaud Level 1 Level 1 (25 points)
    No fix yet. I downloaded Onyx Maintenance (nice app!) but it did not make a difference at all. A.C.

    I also tried running onyx and my keyboard lost connection two minutes after I ran it. I'll try maintenance 1.1.3 but don't think it will help either. If it does I'll let you know. Most of the maintenance tools seem to just clean caches, repair permissions, run unix scripts and test hardware, all of which you can do without them.

    Similar problem here. Just took delivery of a new 24in imac with bluetooth keyboard and mouse. Was very happy with both input devices until I installed the 10.4.9 update 5 minutes ago. Now, my mouse's movement are herkey jerkey. Keyboard also has some lag issues, especially after restarts on logins. How do I inform Apple of this problem? How can I easily go back to 10.4.8?

  • T. Sunny Khamapirad Level 1 Level 1 (0 points)
    Try this (not my idea - found in another forum):

    1) Connect a usb keyboard and mouse to your computer

    2) Go to System Preferences and select bluetooth

    3) Select the device tab and delete both mouse and keyboard pairings

    4) Use disk utilities to repair permissions. (this step may be Voodoo since it did not find any problems with my computer)

    5) restart your mac and remove batteries from the bluetooth mouse and keyboard (did not work unless I physicially removed the batteries; turning it off was not sufficient)

    6) reinsert batteries after a few seconds and turn on your devices.

    7) re-pair the mouse and keyboard using the bluetooth system preference pane

    My mightymouse and wireless apple keyboard now work the same as they did before the 10.4.9 install. Hope it helps you.

    T. Sunny: How to tell Apple? One would hope they are reading these messages and not only programming the next iPod ... Your tips may all be good but I cannot implement them until the BlueTooth control panel works. So far, it is only accessible if BT is turned off. The second I turn it on, it hangs and I have no accesses at all to the various settings there. What is it reading that is corrupt? After dumping prefs and cache files in all users, I have no more ideas. Can anyone think of something? Thanks.

    I would troubleshoot this way:

    On a different partition on your internal drive or ext firewire drive, install a fresh copy of OX 10.4 or even 10.3. Booth from this partiton. See if your bluetooth works. If so, then update to 10.4.9 and see if it still works.

    If not, then your culprit is the update and I would not update on your permanent boot partition.

    If yes, then migrate all your stuff to the new partation or double migrate to the firewire disk/erase old partition/migrate back.

    If you bluetooth does not work with a fresh copy or OS 10.4 on a new partition/ext drive, then you may have a hardware issue. Try borrowing a USB bluetooth adaptor from your local computer store (leaving with them your refundable retail deposit price of course) and see if you can get it to work. D-link usb/bluetooth adaptor ~$25 works on my old blue&white frankenmac G4 with 10.3 installed. May want to unplug your internal bluetooth module inside your case (if possible) when you do this so that OS 10 does not freak out.

    That's all I know.
