Disappointingly indeed, it has always some bugs and problems when trying to send files from our iPhone to Mac. AirDrop from iPhone to Mac Not WorkingĪlthough AirDrop has existed on Mac for even longer, Macs and iOS devices were unable to communicate with each other due to differentia in the technology required. If still not OK, try to transfer files between iPhone/iPad and PC/Mac without Apple ID using an iPhone/iPad File Manager. Click on 'Set' next to Apple ID to re-add and reset your Apple ID.Highlight your Apple ID > click the minus sign to delete it > click 'Done'.Enter your computer's password in pop-up box.If all have checked well, but still not working, click 'Change' next to your Apple ID: (This method may equally applies to the situation when on the same network, one device can find another device which cannot recognize the other). Make sure the receiving device has your phone number (or Email) that is associated with your Apple ID in the Contacts.Make sure both devices are signed in to iCloud.Make sure you have set up to receive items from contacts.Look for your Apple ID, make sure you have your Apple ID filled out.Go to System Preferences > Click on 'Users & Groups'.Going from my wife's MacBook to my MacBook Pro it was saying, "The Apple ID certificate for is invalid."

When I send a file from my computer to the other computer using AirDrop, it would pop up a message saying the other user disconnected/denied the connection.
