After running the 10.13.4 update, I have been getting this error (see screenshot attached) along with a “The disk you inserted was not readable by this computer” error about 10-15 seconds afterwards. It doesn’t happen every time but usually 2 of 3 times gives me this error.
I imagine the disk not readable message is from the DMG creation failing but haven’t seen that before when it fails. Been running this same script for the past 2-3 years without fail.
Thanks for any help.
