Welcome @Jezmund
- Is your co-worker running a Mac?
- What kind of access would the co-worker need?
- Will the Mac Mini be an issue? Should I instead put this at MacMini Colo or similar?
I don’t see any inherent issue using the Mini where it’s at.
Regarding sync…
There is a forum post on syncing: Sync Types Explained
There is also one specifically about Bonjour: Bonjour Simplified
Sync is covered in the Help for each application:
- For DEVONthink, sync is covered in the Help > Documentation > In & Out > Sync, Preferences > Sync, and Troubleshooting > Sync Issues.
- For DEVONthink To Go, sync is covered in the ? > Help > Sync your databases section.
There are also manuals available here: Manuals
