Funny you should ask…I did run my own CalDAV server, on a Mac Mini I bought specifically for that. On software that took less than hour to set up, but then Apple discontinued macOS Server. I don’t know anyone who successfully setup the open-source calendarserver from the “directions” provided. Furthermore, it is no longer supported and the site is read only. I personally spent two days on three separate occasions trying to get it to work.
I would welcome recommendations for either a LINUX installation that includes CalDAV or an affordable, NAS w/ CalDAV and adequate performance.
Sorry, huh?
