Definitive answer here : > [@Distribution of FMOD Studio Libs on Catalina/Big Sur in Integration](https://qa.fmod.com/t/distribution-of-fmod-studio-libs-on-catalina-big-sur-in-integration/17283/9): > > We’ve got to the bottom of this issue for now. If you download a zip file from the internet or even a LAN (possibly containing a Unity project with the FMOD integration already installed) and open it using a program that uses the macOS system zip functions (e.g. by simply double-clicking the zip), macOS will apply the quarantine flag to any executables and shared libraries it finds as it extracts them. This means that if you transfer a Unity project that has the FMOD integration already install… It’s true, it never used to be a problem with older versions of macOS but Apple keeps updating its security measures and introducing new safety requirements in macOS itself so it’s not something we, as the developers of FMOD, have the power to fix - it’s just how macOS is these days. --- _[View the full topic](https://qa.fmod.com/t/fmodstudio-l-bundle-is-damaged-macos-catalina/20257)._
