... That is, put a little shell script in the application bundle, and invoke it (in Release, though not Debug where it interferes with Xcode debugging) See commit 07661c186f7e8e6d978fa35485d65364b96dfb3a The shell nulls the environment variable DYLD_LIBRARY_PATH and then executes the main program. This is needed because changes to DYLD_LIBRARY_PATH during the main program's run fail to affect the loading of dynamic libraries afterward. We need null in DYLD_LIBRARY_PATH to make absolute paths to libraries take priority. More info: Documentation of workings of the macOS dynamic loader https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/DynamicLibraries/100-Articles/DynamicLibraryUsageGuidelines.html The same problem and solution is discussed here https://stackoverflow.com/questions/6713692/problems-with-using-setenv-and-then-making-the-dlopen-call It is claimed there that Firefox did the same trick with a shell, which I do not observe in my version, but GIMP 2.8.16 does this, as I can see by examining package contents Also note the mention in this commit's comments (where the script was removed because bug543's fix left it unused), that the script also used to interfere with signing. I hope that there will be a way around that. 98186b9317adf842e0469fe98175b55da31d3210
