Mac OS X 10.6.4, MacBook Pro, Apple Magic Trackpad.

The trackpad is unresponsive. Right-clicking on the Bluetooth icon in the menu bar shows me gray text that says "Bluetooth not available".

I don't see a system preference item in which to fight with this, but I don't see anything relevant.


According to this article, resetting the System Management Controller might to the trick.

Here's how to Reset the SMC on Apple's support site.


Under System Preferences there should be a bluetooth preference pane. Make sure it's set to 'on' and 'discoverable'.


In terminal, also remove the com.apple.driver.AppleBluetoothMultitouch.trackpad.plist and com.apple.driver.AppleBluetoothMultitouch.mouse.plist files from ~/Library/Preferences.

cd ~/Library/Preferences
rm com.apple.driver.AppleBluetoothMultitouch.mouse.plist
rm com.apple.driver.AppleBluetoothMultitouch.trackpad.plist

Then restart. That fixed it for me.

  • What does "also remove" mean here? What needs to be done addition to the removal of these files? – nohillside Mar 9 at 10:18

    And why do you use sudo to remove files owned by the current user – nohillside Mar 9 at 10:19

Resetting the NVRAM as described here solved the issue for me:



I fixed it by

  1. shutting down the machine
  2. removing battery
  3. keep power button pressed for 10 sec
  4. start machine again

    At which point did you insert the battery again, 2b? And how long did you remove it? – nohillside Jun 5 '12 at 20:52

I have fixed by the same method as above. shut down, remove battery, hold down power button for 10 seconds, replace battery and re-start
