iMac OS X Yosemite Mid 2011
I have a problem with AirDrop and have searched for solutions none of which have worked
AirDrop works fine (can send and receive files) when I open it after boot up the system but if I close the window or even leave the window open it will stop working this happens and can be replicated without fail. I have not yet found anyone else to have had this exact problem which may suggest it to be a problem with my machine alone but it was working fine until an update to the OS (don’t know the exact update). but it was in the last 4 months.
