Hello all! I'm new to JAMF. We have installed Mac Mini machines to be content caches for our iPads in the school system. They are set to configure themselves when they are plugged into the network and powered up. The default name is mac mini. I go and manually rename each one after it comes up. But for some reason, a couple of days later, the name has reverted to mac mini. I look in the history in JAMF and it only shows when it was created and each time I have renamed it. Any logs I can look at other than the history for the machine? Any ideas?

Mini Mac Computer Name Reverts to Default

The value you want to set the name to will depend on your own choices - as an example I have a script which reads the name of the 'asset' from an asset database called SnipeIT but for simplicity I will use the Mac serial number as an example. Therefore the core of the script will be as follows.
#!/bin/bash
#
serialNumber=$(system_profiler SPHardwareDataType | awk '/Serial/ {print $4}')
/usr/local/bin/jamf setComputerName -name "$serialNumber"
exitThe jamf command not only sets all three computer names in one but also sends the new name to Jamf Pro to update the inventory record.
We are doing basically the same thing, just backwards. I prefer to write my scripts to be MDM agnostic, that way they can be run locally without issue and not needing JAMF. The JAMF recon at the end of my script, updates JAMF as to what the devices hostname is.
My script is a little long, but mainly because it uses a lot of variables, comments and "error" checking. The bones of my script is 3 lines. If you are not setting all 3 of these, you are not seeing the hostname correctly.
scutil --set ComputerName "$serialNumber"
scutil --set HostName "$serialNumber"
scutil --set LocalHostName "$serialNumber"The rest of the script is gathering what the serial number is, and making sure each of the 3 lines above actually need to be run with a ton of comments. This way you are not needlessly making changes. With a finally check to make sure the hostname actually changed and it will error if the hostname did not change.
+26For the Mac Mini's I suggest using a script to set the host names. MacOS needs its hostname set in 3 locations or it wont stick. Below is the script I use to name our Macs. I have it set to run on enrollment and on a recurring check in against a group for devices that don't meet our naming connections so I can set it and forget it. I use the Serial Number for the host name, but you should be able to update this script to meet your needs.

+1Hi. Don't know if this will apply to you, but for our AppleTVs this worked.
- In the default DEP profile, Set Device Name to the variable %Name%. This will make the name stick after a refresh or reboot.
