Thanks, Quinn, it took a little time to find the needle in the haystack but your links were super helpful and you were indeed correct. For the record Qt was not at fault but due to issues with how our application was deployed and how some 3rd party libraries were being built with Conan we needed to fix a handful of references to directories outside the bundle that opened the application up to a dynamic library impersonation attacks because library validation was correctly disabled (we do not and cannot ship with our application the weakly linked library in question). What boggles my mind is that there is no tool widely available to check for and alert to issues that can only be exposed by extensive calls to otool -l and otool -L. To rectify this, and to successfully track down the issues we had, I wrote such a script and have made it available for others to use: https://github.com/wstokes/developmentTools/blob/main/mac/audit
