How to pair PS3 controller with mac 2017

I've been scouring forums trying to get my ps3 dualshock controller to connect to my mac but some say to favourite the device in Bluetooth or unplug the controller and stuff. But now in the new update of Bluetooth the small gear symbol that allowed you to favourite things is gone and nothing else I look for can help me.

my controller successfully connects to the mac but does not pair or ask for a password please help
