iMessage unable to send attachments (pics, vids, documents, etc)
Since high Sierra, I have been unable to send attachments via iMessage on my MAC. I have 2 Macbook Airs and 1 Macbook pro. All of them have the same issue. In order for me to send something other than typing a text message, I have to airdrop it to one of my iPhone or my iPad and then send it from there. When I send an attachment from any of my Macs, the receiving end just gets a 0byte file. It never completes. However the Mac iMessage shows that it delivered it. I have both Airs on High Sierra and the Macbook pro on Mojave.
This all started when I upgraded my Macbook Airs to High Sierra from Mavricks.
Anyone have a clue on how to resolve this issue?
MacBook Air 13", macOS 10.13
