I appreciate the ongoing responses. The only other options in the Mac OSX Disk Utility are MS-DOS (FAT), ExFAT, or Mac OSX Extended.
My shortest answer is: I am simply looking to transfer files from My Mac Computer to Pure OS, once I have the Purism 15" Laptop. Not really looking to do anything fancy, just simple file transfer of my music and other document files (PDFs, Office Software Files, Jpeg’s, etc.).
Edit: Unless it is a bit more complicated than I thought.
