In addition to the suggestions above (using the VST version of the plugins on both PC and macOS), another good strategy in general for sharing projects is to use
File >
Save Project As with the following options checked at the bottom of the Save window:
- Create subdirectory for project
- Copy all media into project directory
This way all the necessary audio files which are used or imported into the project are saved into a single project folder.
