I am no IT guru , but I do run a MacBook Pro (on Yosemite) , iPads and iPhones Just a couple of ideas for you to try:
1 Try plugging both iPad and MacBook into the mains via their chargers, and ensure both have access to WiFi. This allows the devices to synchronise.
2 If this does not work ensure that everything is all synchronised to the Cloud, some of the new drivers on Yosemite take a while to set up properly
3 If all of this still does not work book an appointment at the Genius Bar at the nearest Apple store to you.
