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.

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')
