Hello,
I think that the same error happened to me, when I moved all my build to Mojave machine....
will check out if that was the same issue, but the DMG that I produced and was posted was built on osx Sierra.
Sorry if I am that backward :)
It may be, that we would need to use higher Qt version for Mojave.
(I started experimenting with Mojave, but I was unable to find more time to get through)
Thanks for the input,
Cheerz, Z
