Hi I've got the following setup: 1 central NAS (Buffalo) my iMac where I sync my iPhone my wife's i Mac where she synces her iPod Touch. All connected wired through 1GB Network. I would like to keep all music and apps on the NAS centrally so that all music added (1% from store, 99% ripped from CDs) and apps added will be available to both Macs and both devices. Does that work at all (sharing apps?)? After many trials I think I do have the central library for music working, but when 1 iMac has iTunes open, the other can't open iTunes due to "iTunes library already in use or no write-access." What am I doing wrong? Thanks a lot Martin PS: I have went through the whole forum and haven't found a post to help me with this, if I missed one, please forgive.
