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.

  • I could not turn on Bluetooth and this helped. In short: 1. Shut down the computer. 2. Press and hold the start button for 10 seconds. 3. Wait for a few seconds and press the start button again to let the computer boot. Voilà!

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?

    And why do you use sudo to remove files owned by the current user

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

Had this problem since 2015 and I have tried just about everything suggested by this thread similar ones. The only solution I have come across that works 100% for me is by going to System Preferences -> General -> unchecking Allow Handoff between this Mac and your iCloud devices

It has been a month of observing this problem that occured daily and never had an issue afterwards. Hope this might help some of you out there.

  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?

  • Better to follow the “how to reset SMC answer” since the steps vary per hardware.

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
