You will need access to the root folder of your file system
The error log suggests one of this paths:
‘/private/var/containers/Bundle/Application/C6152FFF-E11A-49EC-8DC8-4B0C43582BD2/BallDasher.app/Frameworks/libSDL2.dylib’
‘@rpath/libSDL2.dylib’
‘/usr/local/lib/libSDL2.dylib’
‘/usr/lib/libSDL2.dylib’
The first one must be the correct path of a successfully packaging process but I think you can try anyway of that list.
I’m going to investigate why the thirdparty libraries are not packaged in the expected path.
