Woke up my computer this morning for the usual post breakfast mail and web check to find an alert on the desktop which reads:
This computer’s local hostname â€Andy-Reids-Computer-2-local†is already in use on this network. The name has been changed to â€Andy-Reids-Computer-3-localâ€.
What? Why? I have updated several apps in the past few days in preparation for the leap to Mojave (eg Diskwarrior, Carbon Copy Cloner, ClamXav) but haven’t, as far as I know, done anything to initiate a change to the local hostname. I did connect and format (HFS+) a new SSD drive for post Mojave clone purposes but it doesn’t seem likely that this is the culprit.
I haven’t changed the hostname back in the Sharing Preference yet and maybe I shouldn't. It may be a non-issue but something, as well as standard security paranoia, tells me it’s a bit odd. Does anyone have any ideas?
