OK, have a late 2013 MBP with Yosemite 10.10.5 and an iPhone 6+ with iOS 9.1. I cannot seem to connect them to each other with Airdrop. Sometimes I will see my wife's iPad and the phone, but usually I see nothing in my MBP Airdrop view. When I DO see my phone, the minute I try to transfer something from the phone to my MBP the icon in my Airdrop folder disappears and my iPhone just indicates 'waiting'. I have both Bluetooth and Wi-Fi enabled on both devices. On my iPhone I have "Airdrop: Everyone", same for my MBP. Somehow I thought this was supposed to 'just work'. How do I troubleshoot this? Thanks in advance.
