I started with this post and was able to connect the Apple Bluetooth Trackpad but not the Apple Bluetooth Keyboard.

And as part of the steps I have updated the system and installed the bluetooth related utilities.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install bluetooth blueman bluez python-gobject python-gobject-2

Then I came across Connect Apple Wireless Keyboard to Raspbian (Jessie) and it guided me guided to the success pairing of Apple Bluetooth Keyboard and Bluetooth Trackpad.

All I need to do for every RPi start/restart is to restart the apple wireless keyboard, and it automatically gets connected.

I am using this bluetooth dongle
