I’m referring to the Operating System…  
The newest/latest OS supporting your Mac Pro 1.1 will be OS X 10.7 Lion (latest public release of macOS is 10.14 and 10.15 is just a few months away). OS X 10.7 only support Plex Media Server versions [0.9.16 or below](https://forums.plex.tv/t/plex-media-server/30447/118)… those releases are 3+ years old!

Server versions that old won’t run with current versions of Plex clients (e.g. on Android / iOS).
