Any clues as to what could be causing this on the side of the Mac? I'm thinking some sytem-level security but really just guessing.

Qt 4.8.6 is long EOL, so indeed it's possible that is has troubles with modern macOS versions which didn't exist when it was released
Is it happening inside sanbox, by chance?
Anyway, you should consider migrating to Qt 5 ASAP
