Hello!
So, Currently I have been having issues with Naming of machines, this isnt happening on ALL the machines just a handful and i can't seem to fathum why...
I'm using a policy that has a reccuring check-in, using the maintenance 'Reset Computer Names' to make the changes in jamf transfer onto the machine in question.
Now, the names will change in jamf but after a few days it will revert back to something like 'imac(8)' and not what i previously set...
Any help?
Can you link the script you are using? MacOS has its hostname set in 3 spots and you need to change all of them.
This is the script I use, it may have some functions you dont want or need but it works.

Does the computer name completely change or does it just add a number (5) to the end? If it is just a number, this is an issue with bonjour network discovery. Macs use bonjour to find other network devices that can be connected to. However, it does not like having two computers with the exact same name (i.e. MacBookPro). The problem we have seen is that sometimes a computer sees itself and thinks that it is another computer and updates it's computer name. I have some computers with five digit numbers appended to the end.
I haven't figured out how to prevent this.

Thanks for the script, ill have a nosey!
Currently not using a script, just the built in feature on jamf to rename machines and to change the machine name to match the one in jamf...
Could explain why I'm seeing issues...

It will go from something like 'Room2-Mac1' to 'imac2'
Its really fustrating when soemthing so simple is yet so complex.

Does your script just rename it to its serial number? We have naming conventions that go by room names ect
It will go from something like 'Room2-Mac1' to 'imac2'
Its really fustrating when soemthing so simple is yet so complex.
you change on the Mac.. jamf reflect this. if you edit the name in the device record in jamf.. next time it recons, it picks up the name from the Mac.. script is the way forward

Would that be the case when running this?

If JAMF has something like MacBook Pro listed as the hostname it will attempt to sync that down. If there is already a "MacBook Pro" on the network, then macOS will append a number at the end like MacBook Pro (5). Host names must be unique on a network.
To really use that check box you need to be doing something to randomize the computer name in the inventory record. You could do this manually, or use JAMF API and some scripting. I prefer to steer clear of that noise and just adjust the hostname with a script, and use smart groups to make sure the name sticks. We use the serial number for the hostname as that is nearly assured to be unique.

We use Serial Numbers, yes. I have other ways to identify where a device is like network locations and buildings/rooms/popup extension attributes.
The only important part of the script is this bit, everything else can be changed to meet your needs.
scutil --set HostName "something here"
scutil --set LocalHostName "something here"
scutil --set ComputerName "something here"
You could also simplify the above script a bit and use the Jamf binary to set the name. Something like:
SerialNumber=$(system_profiler SPHardwareDataType | awk '/Serial/ {print $4}')
jamf setComputerName -name $SerialNumberI do something like this and trim the last 7 digits of the Serial Number:
SerialNumber=$(system_profiler SPHardwareDataType | awk '/Serial/ {print $4}' | grep -o '.\\{7\\}$')Then use a standardized prefix plus the trimmed SN:
jamf setComputerName -name "UA-"$SerialNumberFor an output like: UA-ABC1234
Food for thought...
