In my finder, Airdrop doesnt bring out the option to " connect with contact, everyone or everybody" it just shows Airdrop without the ability to connwct with my iphone

My mac book usually shut down during operation and i have tried all i could to stop this but it still happens, what must i do?

Secondly i cant Use my Macbook Airdrop as there is no option for "connect with contact, everyone ...", i only see the Airdrop in the finder but it wouldnt even bring out options or connect. I need to understand what i must do to change this
