My brand-new MacBook Air (2011 11") has never been connected to anything Bluetooth. Neither had the previous Air I migrated from. I never use Bluetooth, although I do plan to get start using a Magic Mouse occasionally.

 

BT was on out of the box, but I turned it off. I intend to keep it off all the time except for certain future mouse tasks.

 

But several times a day I notice it has turned itself back on! I turn it off, but it never lasts.  (I keep the BT icon in the menu bar so I can watch the situation.)

 

Any fixes? I don't want any needless battery drain.

 

Thanks in advance!

 

(Also, I notice that the Prefs checkboxes that bring up BT Assistant when "no keyboard [mouse/trackpad] is detected" cannot be turned off. No big deal--the assistant never appears anyway, since obviously a laptop can't have that situation! But I still thought it might be a related symptom: when you uncheck either option, a confirmation sheet drops down. But it doesn't matter which choice you make on the sheet, the boxes stay checked.)


MacBook Air, Mac OS X (10.7), 4GB i7

    The pattern seems like it might be sleep-related: BT doesn't come on every time I sleep and wake, but I do notice that happening sometimes. And as I've been watching, I haven't noticed happening at other times (but I could certainly miss it).

    I have the exact same problem, but have no solution yet.  I've also noticed a steady increase in the time it takes my laptop to wake from sleep.

     

    i'm running on a 2011 13"  macbook air.

     

    as far as i've noticed the problem seems to be sleep related.

    I have the same problem with my new macbook air 11" hope somebody would find a solution.

    Same here :-( hopefully these posts will suggest to Apple that is not am isolated problem

    The pattern seems to be:

     

    - If I sleep the machine for just a short time, or close the lid and open again very soon, Bluetooth stays off, just as it should

     

    - If I sleep for longer (half hour? hour? not sure) then BT turns itself on when the machine wakes, wasting battery power.

    I have the same issue on a MacBook Air, 2011 model, 13.3". One hint would be that I did a transfer from my previous MacBook Pro to this one right after first power-on, if that may have anything to do with the problem...

    I also purchased the 2011 13" MBA and used the migration assistant to migrate from my 2010 11" MBA. I have the same issue. Bluetooth keeps turning itself back on and seems to be sleep related.

    I also cannot keep Bluetooth off. If I restart, it is on. I too used the Migration Assistant option during the initial bootup of the MacBook to import a user from another computer. This is on a brand-new MacBook 13" (i5)

    I had another issue after using migration assist, where there was a file that was in snow leopard, but not in lion.  In that case it was a bootup file for PPC support, which was dropped with the release of lion. 

     

    I think there might be a similar issue with the bluetooth, however, i don't have time to scour the interwebs for the correct file.  I might go into the genius bar later this week and see if they can give me a copy of the folder that isn't botched.

     

    I'll be back on to post results, or just to say that i didn't have time... who knows.

    Same problem! Brand new Macbook Air....13" 2011....I keep turning bluetooth off and it keeps going back on!! Same with the inability to turn off hte same options in bluetooth preferences as the original poster mentioned.

     

    I also used Migration Assistant from my Macbook Pro...but I doubt that has anything to do with it.

     

     

    Oh....maybe the migration DID have something to do with it....

     

     

    I just deleted all the bluetooth plist files from the ~Library folder and restarted and bluetooth did not start up...and now I can DEselect the boxes I want in the Bluetooth Prefs

     

     

    So tht appears to be what might work....DELETE the bluetooth .plists in the MAIN Library folder and restart.

    The problem definitely doesn't seem to happen with brief sleep periods; so maybe it's related to the "deep sleep" mode.

    The missing PPC file sounds normal to me, since PPC support was dropped.

  • fabes89 Level 1 Level 1 (0 points)

    Hahaha, i should specify, the file was supposed to be missing, since support was dropped.  But, it was copied over anyways, and it kept causing errors when starting up.  It was easy enough to fix though... i just deleted the file.

    Delete the bluetooth .plist files in the MAIN Library preferences folder and restart......

  • raymstoi Level 1 Level 1 (0 points)

    Worked for me.  There were four Bluetooth plist files to delete:

    com.apple.Bluetooth.plist (folder)

        com.apple.Bluetooth.plist (inside the folder)

    com.apple.Bluetooth.plist.lockfile

    com.apple.Bluetooth.plist~orig
