Airdrop Mac

Hi,

I have a MacBook Pro 15 inch (Mid 2010), Processor 2.4 GHz, Memory 4 GB, Version OS X El Capitan 10.11.4

I have recently downloaded this version on my mac. I found AirDrop on my finder, but it does not give me any options below "Discover by ...."

I have went through all troubleshooting steps, but it still doesn't come up. I also re-installed the software, restarted the computer, still nothing.

My wifi is on and my bluetooth is on and connects with my phone. But my phone doesn't pick up my mac in Airdrop vice versa. My phone setting for AirDrop is Everyone. I don't know what to do next. Please let me know what is the next step.

Thank You
