Hey, guys, I've updated to Yosemite on my late 2011 MBP, but it can't seem to detect other devices. I've enabled Wi-Fi and Bluetooth, but the AirDrop section in Finder just says "AirDrop lets you share instantly with people nearby..." -- it doesn't even let me toggle its visibility. Both my iPhone 6 and iPad mini are running iOS 8.0.2 with AirDrop enable for everyone. I'm really not sure what else I need to enable. Any help would be appreciated. Thanks in advance!
