I recently downloaded xbvr on my Mac, and so far it’s been running in Terminal for 72 hours. Every 2 hours it scans (screenshot below), a process that “may take several minutes” according to the xbvr site.
Yeah, think that’s normal: it needs to keep running as it’s a server. Because xbvr isn’t really mac-like it doesn’t install itself as a Daemon or Agent through launchd, so it needs to run in the background in a terminal instead (you can quit it with control-c or just close the terminal window).
