## TL;DR
Scope a policy or app assignment to just that device (Jamf: policy scoped to the single computer; Intune: app assigned to a group containing only that device or user), trigger a check-in, and verify installation. Remove the one-off scope afterward so it does not linger.

## The error
```text
(Deployment request; no error.)
```

## Steps
1. Jamf: create a policy with the package, scoped to the single computer (Computers > the device). Intune: assign the app to an Entra group containing only the target user or device. Expected: scope limited to one.
2. Set the trigger: Jamf "check-in" or Self Service; Intune "available" or "required". Expected: configured. For urgent needs use required/push; otherwise Self Service avoids surprise installs.
3. Trigger a client check-in: Jamf `sudo jamf policy` on the Mac, or Company Portal sync for Intune. Expected: policy runs.
4. Verify: Jamf inventory shows the app installed, or Intune app install status is succeeded. Expected: confirmed. Do not trust "assigned" alone.
5. Clean up: remove the one-off scope or delete the single-use policy. Expected: no lingering targeted policies. Lingering scopes cause confusion later.

## When to use
- One user needs software now
- Testing a package before fleet rollout

## When not to use
- Fleet deployments (use proper group scoping)
- Recurring installs (make it a standard policy)

## Compatibility
- Jamf Pro (macOS), Microsoft Intune (Windows/macOS/mobile)

## Variants
### App must install without user interaction
Use required/push assignment, but warn the user first.
### Test before fleet
Scope to a pilot group, verify, then widen.

## Why it happens
MDM deployment is scope-driven. One-off requests need the same machinery as fleet rollouts, just scoped to one target, and the cleanup matters because forgotten scopes accumulate.

## Edge cases
- Name one-off policies clearly (ONEOFF-username-app-date) so they are findable.
- Some apps need a reboot; warn the user.
