The installer won't run on a Mac, except possibly through something like WINE/Crossover Office, but you can copy the files from your laptop. At worst you will need to use P3DO to convert the rsr thumbnails to pngs before doing so, or to live without thumbnails, but the working files are cross platform. Remember when transferring that Macs don't merge folders so you can't just drag the Runtime from the laptop into your mac content folder - you need to move files, or folders that aren't already on the Mac, individually.
