Airdrop when will it "just work"

I think airdrop is great ... in concept

However its implementation is just hazy; it works one in three times on average. And when it fails there is absolutely no way to understand what's wrong.

So now I try airdrop; and if it does not work I give up instantly and revert to good old USB stick.

But this is not right; so I'm wondering if someone has; or knows of; a definitive guide to make airdrop work first time.

Thanks

 

Ok, for Ducki, yes I am certain all settings are correct; and I noted that if wifi or BT are not active the os actually asks me to activate them. And the setting is for all users so there is no filter here either.

Yes, terribly unreliable, worst, its supposed to be that quick and easy connect and ends up taking more time than usb; shameful I would say.

Wish there was some sort of "info" panel that let me know the basics each airport system has; so that I could spot the differences and try to resolve them. Or something of the sort.

 

Indeed that's what I do mac to mac; but from iOS airdrop has great "potential".
