I installed Plexconnnect using Open Plex (ibaa Baisc theme)
Tested with ATV 3 .. Worked good.
I kept above given 3 plist in ~/Library/Launchagent (In User homedirectory).
I see these new PID post reboot.
469 - com.plexconnect.wake_web
470 - com.plexconnect.wake_pms
471 - com.plexconnect.wake_dns
i gave a try .
Put mac in sleep mode (Lightdimming) .. Then i browsed , Plex (Via trailer) ... wow it worked .. Plex came with library .
Was happy ..
Tried Second time
Plex screen comes but without library . I get a message on screen - Plex can't connect to library
Seems this to be error and trial ..
