For some reason, I can’t drag audio files (assets) into events because fmod will only highlight the assets instead of allowing me to drag them, I have no idea how this started, only that it randomly occurred when accessing the software.
There was an issue with using FMOD Studio 2.00 and earlier where more modern versions of macOS would cause the drag & drop to not function correctly. This has been fixed in FMOD Studio 2.01.00 and later.
