My interest in file systems started when I discovered how type and creator codes1 and resource forks contributed to the fantastic user interface on my original Macintosh in 1984. In the late 1990s, when it looked like Apple might buy Be Inc. to solve its operating system problems, the Be File System was the part I was most excited about. When Apple bought NeXT instead and (eventually) created Mac OS X, I was extremely enthusiastic about the possibility of ZFS becoming the new file system for the Mac. But that didn’t happen either.
