Thanks for the quick reply. That is our Team ID, correct. This was actually purely user error. I should have read this thread closer. I'd entered the Hardware UUID and not the Provisioning UDID. A little confusing as the Apple Developer device registration, for macOS, asks for 'Device ID (UUID)' but is actually expecting the UDID. But again, purely user error.

Thanks for the quick response. That is the correct Team ID. This was pure user error. I should have read this thread a little closer. I'd entered the Hardware UUID instead of the Provisioning UDID. I think what threw me off is that Apple Developer device registration asks for 'Device ID (UUID)' which doesn't exactly match the system information fields. I guess I saw 'UUID' and thought it meant Hardware UUID. It asking for a UUID but actually expecting a UDID confused me. But purely user error.

Thank you! Worked for me.
