You could also use import subprocess completed_process = subprocess.run(['xcrun', 'xctrace', 'list', 'devices'], stdout=subprocess.PIPE, stderr=subprocess.PIPE) all_devices_info = completed_process.stderr.decode('utf-8')

Do you use Parallels Desktop ? Tried that as well and i fear it does not support macOS 15 yet. I instead used https://developer.apple.com/documentation/virtualization/running_macos_in_a_virtual_machine_on_apple_silicon which works fine for macOS 14 but with 15 it seems not to work - which possibly makes sense as 14 does not know anything about 15 SDK's. Not sure if it is currently possible to virtualize macOS 15. If someone knows, let us know.
