Cannot create a macOS vm using apple script

[gnasr]

Describe the issue
I'm trying to script a macOS vm creation following the example in the CheatSheet but the resulting VM is always a linux VM, the documentation seems to be incomplete too, since it doesn't show how to specify boot or operating system parameters in configuration (if it's possible at all).
I don't know if i understand correctly but it seems to be hardcoded that the VM created with scripting will always be linux, am i right? https://github.com/utmapp/UTM/blob/main/Scripting/UTMScriptingCreateCommand.swift#L106

Configuration

• UTM Version: 4.2.5
• macOS Version: 13.3.1
• Mac Chip: M1

If someone can show me how to script a macOS vm would be really helpful.
Thanks

In AppleScript property of object could have property of other object. In other words a nested object.
In normal case the specified object that contents property you use the same method set property of object to value.
UTM have a special method to update configuration.

Here is example how to change memory for VM from 8GB to 4GB.

tell application "UTM"
	set theVMs to name of virtual machines
	if "Fedora 38 ARM" is in theVMs then
		tell virtual machine "Fedora 38 ARM"
			log {"Current memory: ", memory of (get configuration)}
			set newConf to {memory:4096}
			update configuration with newConf
		end tell
	end if
end tell

To make is more clear you need to understand how the nested configuration of specified object work.

set thePath to POSIX path of (path to downloads folder) & "kali-linux-2023.2a-installer-arm64.iso"
set theIso to POSIX file thePath
tell application "UTM"
	set theDrive to {{removable:true, source:theIso}, {guest size:65536}}
	set theConfiguration to {name:"QEMU ARM64", architecture:"aarch64", drives:theDrive}
	set theVM to make new virtual machine with properties {backend:qemu, configuration:theConfiguration}
end tell

(*
{
   backend:qemu, 
   configuration:
   {
      name:"QEMU ARM64", 
      architecture:"aarch64", 
      drives:
      {
         {
            removable:true, 
            source:iso
         }, 
         {
            guest size:65536
         }
      }
   }
}
 *)

The drives object has 2 AppleScript record object.

tell application "UTM"
	tell virtual machine "Fedora 38 ARM"
		set theConfiguration to its configuration
		tell theConfiguration
			set {recordObject1, recordObject2} to {item 1 of its drives, item 2 of its drives}
			-- Return AppleScript record of object 1
			return recordObject1
			-- Return AppleScript record of object 2
			return recordObject2
		end tell
	end tell
end tell

Hello, any update/comment on this issue please ? I am facing the same issue and not able to change "operating system" under "boot" options from "Linux" to "macOC" using the Apple Script.

I do not see any option under "apple configuration" section in the documentation as well.

I tried below code to change the OS configuration but resulted into an error.

`
tell application "UTM"

set iso to POSIX file "/path/UniversalMac_12.0.1_21A559_Restore.ipsw"

set theDrive to {{removable:true, source:iso}, {guest size:65536}}

set theBoot to {{operatingSystem:"macOs"}}

set theConfiguration to {name:"macOS-Name", boot:theBoot, drives:theDrive}

make new virtual machine with properties {backend:apple, configuration:theConfiguration}

end tell

`

Error: "error "UTM got an error: Can’t make "

Thanks for your help in advance !
