I just accepted and installed the most recent update that I was prompted for today 7/11/16. The system has not been able to launch since this update. The windows states that because of the recent update it will update the database which can take longer than usual. I’ve run updates before but never with this type of response.
I have Roon server running on a MacMini with El Captain on a flat 24 bit IP network. The music content is cataloged from 3 separate Netgear NAS for a total of approximately 6TB of data. Is this recent update causing the whole library to catalog all over again?
