Apple Wireless Keyboard not working...

I have successfully installed Kali Linux on my iMac (mid 2010 - 21.5")
Everything is working fine but i cannot connect my Apple Wireless Keyboard to kali (maybe i do it wrong)

I already found this https://www.organicdesign.co.nz/Appl...board_on_Linux
and with the hcitool scan command i can find my keyboard with its mac address so bluetooth driver is working! But i cannot use the hidd --connect XX:XX:XX:XX:XX:XX command to connect to it!?
No such command found.

Im now forced to use the onscreen keyboard with my mouse :(
(On the setup of kali the keyboard worked just fine...)

Ok i found out that i have to start the bluetooth process on every boot manually.
/etc/init.d/bluetooth start
How do i autostart this service? Keyboard works fine and pairs after this command :)
