I've got a Mac at home and another one in my office. I've installed SH3D on both, but I've imported some furniture only on my home mac. Is there a quick way to copy all furniture installed to my other computer?

Related to this, for backup purposes, where can I find the exact file structure of SH3D on a Mac? The program itself is in a directory in the Applications folder, that much is clear, but what about all furniture files? Where are those stored?

Thanks.
