iMac Airdrop setting keeps
My wife uses her iMac and iPad to edit pics for her business. She uses Airdrop to send the pics back and forth, but today her iPad wouldn't show up on the iMac. I looked and saw her "Allow me to be discovered by:" setting was set to No One. I changed it to Everyone, however, anytime we leave the Airdrop tab to grab the files needed and return the setting has been changed back to No One. I have never had this problem before and Google was no help. Any ideas???
iMac, Mac OS X (10.7.5)
