Can't turn Bluetooth on ...

After the latest security update, my Bluetooth is off, and the button to turn it on is greyed out. Anyone know what's going on?
Thanks in advance for any tips.

Try zapping the PRAM:

Or resetting the PMU:

Worked for me a while back.

  • Can't turn bluetooth off, unspecified network in my computer.

    Why can't I turn my computer bluetooth off? And why is there an unspecified network in my computer? And why do the bluetooth file exchange automatically opens at the same time when all the above happens? Why do I have to reformat my computer and import CDs once every few months?can

    When you go to "System Preferences">"Bluetooth" and uncheck the "On" box does it come back on? Or if your bluetooth symbol is in the "Menu Bar" you can click the "Turn Bluetooth Off" in there.
    Check in "System Preferences">"Sharing". Do you have any of the sharing boxes cheked? Your MacBook will search for any computer within range and put it in the sidebar of the "Finder" window. Is this what you mean?
    Why do you have to reformat your computer and import CDs once every few months? What is going wrong that you have to do that?
    And why are you at 10.6.1? Are you not doing Software Updates?

  • How can I turn bluetooth off via terminal or applescript?

    I want to write a short little script that when launched will shut off my bluetooth, I do not need to have the script turn the bluetooth back on. ONLY TURN BLUETOOTH off.
    I really hope there is a way to do this, is there?

    Try posting in the Mac OS X Technologies/AppleScript forum area.

  • Can't turn bluetooth on (possible missing software)

    I can find no way to turn on the bluetooth on my z935-p300. Under Toshiba->Network & Connectivity there is no entry for Bluetooth Assistant and the bluetooth settings icon under configFree does nothing.  I have looked under the updates and drivers for this laptop, and can't find the bluetooth assistant software. Is it part of a larger package? Which one?
    Solved!
    Go to Solution.

    Portege Z935-P300
    Downloads here
    Look in Device Manager (devmgmt.msc) under Network adapters to discover whether you have the Atheros or Realtek..
    I would reinstall the filter driver, the stack, and the ConfigFree utility.

  • How can I turn bluetooth on iphone 5

    When I go into settings, it shows Bluetooth as OFF. When I click to turn on, it immediately goes back to OFF.
    How do I turn on bluetooth?

    Does it actually move to ON then back to OFF? Or does it just not turn on?
    Have you tried a reset, or a restore of the iPhone?

  • After having upgraded my iPhone 4S to iOS 7.0.2, I can not turn on Wi-Fi or Bluetooth. After trying various tricks I found via online forums such as software reset, enable Airplane mode, and resetting the network settings, I have now also completed reset

    After having upgraded my iPhone 4S to iOS 7.0.2, I can not turn on Wi-Fi or Bluetooth. After trying various tricks I found via online forums such as software reset, enable Airplane mode, and resetting the network settings, I have now also completed reset of the phone WITHOUT success. Is there something more to it? If not learn hardly be any more iPhone for me. Really disappointed. Grateful for help!

    If you have tried all of the steps in this support document http://support.apple.com/kb/TS1559 and have completed all of the user troubleshooting, restart, reset, restore from backup, restore as new, then make an appointment with the Apple store to have the hardware checked.

  • Can't turn off Bluetooth

    Just realized that I can't turn off Bluetooth on my iBook. If I go to the menu bar, the "Turn Bluetooth Off" item is dimmed. The "Turn Bluetooth Off" button in System Preference is also dimmed.
    What's going on here? Can anyone help me out?

    There are no bluetooth devices connected to this computer. As well, when I look in the Bluetooth preferences in System Preferences, it says that the Device Name is Unavailable.

    No worries. Often after iTunes updates you have to reconnect your device in order for iTunes to see it. Happens to me all the time!

  • I play music from my iPhone via Bluetooth on the car radio. The phone also connects over the radio. Can I turn off Bluetooth for phone and leave it on for music?

    I play music from my iPhone via Bluetooth on the car radio. The phone also connects over the radio. Can I turn off Bluetooth for phone and leave it on for music?

    I haven't tried it yet, but I believe this would disconnect Bluetooth for both the phone and music. I have a 2013 Hyundai Sonata if this will help.
