airdrop on my mac doesn't recognize any devices
I have mid year 2009 white Macbook (running Yosemite 10.10.5)
Air Drop screen is blank - doesn't show any of my devices
I can Airdrop from my Iphone5 and Ipad (both running IOS10) to other Iphone users with no trouble
Re: System Preferences, I have checked and re-checked Security, Firewall, Bluetooth and Sharing settings
Any other suggestions?
MacBook (13-inch Mid 2009), OS X Yosemite (10.10.5)
