This is reported against an old version of Ubuntu and many things has
changed since then. Because of that we won't fix this issue however if
this behavior repeats on a modern version please fill a bug report
against it and we will take it from there.

Title:
  Bluetooth on MacBook Pro 8.3 Doesn't Work without OSX

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  This bug is kind of hard to describe, but can basically be summed up
  like this:

   * Bluetooth support on a 2011 8.3 MacBook Pro running Ubuntu 11.10 is
  flaky at best and unusuable at worst.

  When I booted up into Ubuntu for the first time, I was pleasantly
  surprised to see that it found my Bluetooth chip and even seemed to be
  working with it.

  Then I actually tried connecting devices.

  Essentially, `hcitool scan` and `hidd --search` both cannot find ANY
  devices. I've yet to actually see it report a detected device
  consistently. ONCE, I saw it report my Nexus One, but then another
  scan and it was gone.

  Devices can only be connected if one boots into OSX first, pairs the
  device, then boots into Ubuntu and attempts to pair the device. Even
  after doing so, commandline tools won't show the device in scanmode,
  only the `bluetooth-applet` and `blueman-manager` show them. After
  connection, I've noticed that I've had inconsistent success with my
  S305 bluetooth headphones, where on another computer with a USB
  dongle, it "just works." Sometimes, they won't establish the
  connection right away and go into pairing mode. Sometimes they'll
  connect fairly immediately, but not be able to be set to A2DP rather
  than HLS mode. Sometimes they'll work but have choppy audio, sometimes
  not.

  There are a lot of other weird things like this such as touchpad
  sensitivity, screen brightness, and more which all require to be
  managed from OSX. This leads me to believe that Apple is doing some
  weird firmware-level or maybe EFI-level system management. This is
  super weird; configuration should be per OS, not per machine.  Has
  anyone heard of their doing these strange things?

  I'm willing to do anything, even including remote SSH access to my
  computer, to help the Ubuntu team resolve this bug. I bought my
  MacBook to run Ubuntu and can't wait to see this stuff work :)
