Magic Trackpad won't pair

[Cave Man]

I have a Mac Pro 5,1. My Magic Mouse has been fine since installation of Yosemite, but my Magic Trackpad won't pair. In the System Preferences Trackpad pane the trackpad shows up but when I try to pair I get the message "The pairing attempt was unsuccessful. Click Continue to try again." But it just goes through the process all over again. And again. And again...

Rebooted. Shut everything off. Even tried manually restarting bluetooth in Terminal:

sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

Fresh alkaline batteries, trackpad is about 1 foot from the Mac Pro. Any ideas? Trackpad pairs fine with my MacBook Air. I just can't get it to pair with the Mac Pro.

Try "unpairing" it from the Macbook Air and then try to pair it with your MacPro.

I've found this to work for me in the past.

This Link refers to the unpairing trick.

If the trackpad is "paired" with MBP then you need to unlink the pair and re pair it withe MP.. Keyboards / Mice / Trackpads can't be be "paired" with 2 different Macs ... Strange..

I ran into this on my MBP after the Yosemite update on both that and my Mini. Even after disconnecting the MTP from the Mini I couldn't get it to link up to the MBP, even if I put the MTP into pairing mode.

I tried it again a few days ago (after MONTHS of not using it with the MBP) and it suddenly connected and worked. No idea what changed to resolve it.

Thanks much. Unpairing was the solution. It seems a smarter dialog for dumber people should have popped up!

Glad I could help.

I had a problem where my Magic Trackpad 2 wasn't showing up on my Macbook after returning to work after the weekend. It wouldn't show up in the pairing screen but did show up on other Macbooks. I reset the computer and the PRAM but still wouldn't show on my machine.

I fixed it by holding SHIFT + OPTION and clicking on the bluetooth icon in the menu bar. Then Debug > reset Bluetooth Module and it worked perfectly.

Nice to see that it's monogamous
