How to transfer photos from Mac to iPhone via Airdrop? This may sound like an easy question, but it's pretty complicated as I found. 
I just want to simple, open my Photos application on my Mac, choose a couple / multiple of pictures to send via Airdrop to my phone and send them. 

When I try to use the Airdrop option after selecting my photos, it automatically selects all and says "Exporting 21 of 2233 photos for sharing". 

How can I do this easily and simply? Move multiple photos via Airdrop. 

Thanks
This is a workaround:


Select your photos
Right click --> edit with --> preview
In preview, hit the share button --> airdrop
