I have a Mac mini running Mac OS High Sierra and installed the DVR software. Two times I have noticed that the DVR software wouldn’t update even though there was no recording , com skip or other processes. The first time I rebooted the server to update MacOS and it did a version update. The next time I had the 11/01 version and was waiting for the 11/03 until I use launchctl app to stop and reload the dvr software on 11/15.
I didnt see anything in the log that was revealing.
I have a manual work around .
