Yes, but you need a NAS to do this, otherwise Plex still demands your computer be on to run Plex Media Server. In your case the NAS is on all the time.
Yes, of course something has to be on running a Media server. I prefer that to be NAS, which is a small low-powered ARM system. I can run Plex on a NAS, but I need a computer to run an iTunes server.
Does a NAS store all of my media files, as well as run Plex? I was thinking of purchasing an external HDD to store them all on, but obviously this means keeping my macbook on. If there is a way to do this on a NAS that seems much better!
May I ask if you can recommend one which will work? Thanks
