And to document what I found out today so it gets on the list.
Files generated in ~/Library/Logs have no user name as they are supposed to. In there I have
LabVIEW.app_21.0b11__cur.log
LabVIEW.app_21.0b11__log.log
That long underscore is really 2 underscores and should have the user name in it. I use the option to use my login name as my LabVIEW id.
