Register an Apple TV.
No Mac, no cable. Type one short address on the Apple TV and it sends us its UDID.
Type this on your Apple TV
https://tv.p12.ru/HL8RZV
Type it including https:// — without it the Apple TV can fail with “check the url”. Code HL8RZV · works for 24 hours. Leave this page open — it updates by itself.
- On the Apple TV: Settings → General → Privacy & Security.
- Highlight Share Apple TV Analytics — highlight it, don't open it — then press the Play/Pause (⏯) button on the remote. A hidden Mobile Device Management screen appears.
- Remove any profile already listed, then choose Add Profile.
- Type https://tv.p12.ru/HL8RZV — including the https:// — and select Done.
- Choose Install, then Trust.
Waiting for your Apple TV…
Switched. On the Apple TV, remove the profile you just tried, choose Add Profile and type the same address again. It will say Unverified this time — that is expected; choose Install anyway.
Can't find the hidden screen?
It only appears while Share Apple TV Analytics is highlighted. Press Play/Pause on the remote, not the touchpad click. On older tvOS it sits under Settings → General → Privacy.
