Unlike this question Local hostname is already in use on this network? my computer was already turned on but 'closed' and when I opened it today I received this message:
This computer's local hostname "(myname)-MacBook-4.local" is already in use on this network. The name has been changed to "(myname)-MacBook-5.local" To change the local hostname, open system preferences and click Sharing, then click "edit" and type the name in the Local Hostname field.
This is the 4 time that I have received this message.
Should I worry about?
What can I do?
The first time that I received the message was in July and I did what dan said in his answer on the linked question, and it turned out that there was just one IP address, so "this error message was probably an internal bug within the MacOS way to manage its DNS cache." according to dan. Then I got the other 3 messages (at different times) and I did nothing.
However, I did this again today and now the
dns-sd -G v4 (myname)-MacBook-4.local hangs on the ...STARTING... stage
If someone could help me, thanks in advance.
