SL Studio Personal
You can download the Sign Language Studio Personal version (MacOS X 10.12.x or later) here:
This app allows you to setup media playlists for SL Studio Group, SL Studio KH (Kingdom Hall use), SL Studio AH (Assembly Hall use) and now also KHAudio (Kingdom Hall sound system) and Cobalt (Assembly Hall sound system).
If used for Sign Language, media can be automatically synced to your personal system using SL Media Updater (see SLStudio Media Updater). For use with KHAudio systems, all media needs to be manually dragged in as KHAudio will not have the sign language media set available. But any added videos, still pictures, PDF forms that you add to your playlist will certainly play on any of the mentioned systems.
