Thanks for the effort, looks like maybe permissions or some kind of proxy issue.
That “var” folder is where alot of installers put temp install files.
some of the services mentioned are sub apps located in the privelege tools folder in Library.
When I looked at the file TelemetryUploadFilecom.microsoft.autoupdate.fba.txt in...var/folders/k5/d92xjhfd0gzgvwd9132_pnm0000gn/T, I saw the following (failures noted in

In my case, MAU indicates that it is downloading a file (or files) and then generates an error message: "Update error...Sorry, there's a problem with the downloaded file, so you can't update now. Please try again later." It seems like an attempt to register
fails and then a web request to /Actions fails with a file/URL not found (error 404.)
