My office has four Macs connected on a shared network. I cannot navigate to all of the shared drives through Media Browser. Do I need to add each drive individually somehow or is this just a glitch? Here is a screen grab showing the drives I am connected to compared to what appears in Media Browser.
Make sure all the drives you want in Premiere are mounted on the Mac. In the finder window, click and highlight each drive you want individually. The eject icon that appears to the right of the name will let you know that it is mounted. Then it should show up in Premiere.
