The client device isn't associated with org_id. The org_id attribute is blank.
```
mdatp health --field org_id
```
Run the Bash script to install the onboarding package:
```
sudo bash -x MicrosoftDefenderATPOnboardingMacOs.sh
```
Verify that the device is now associated with your organization and reports a valid org ID:
```
mdatp health --field org_id
