FULL DISK ACCESS
I have just purchased the latest version of ATI for my MacBook Pro and just updated my Mac on the latest version of Mojave 10.14.5 (18F132) (May 13, 2019).
I have followed the instructions to the letter, watched videos, read all the forum messages but when I drag the icon into my unlocked Full Disk Access nothing appears, yes I have hit the quit button, even tried the quit later option but nothing appears, I have even saved the two files to my desktop and then tried to add them either individually or dragging them both into the frame but still nothing!
