- Encrypted DNS (DNS-over-HTTPS)

- Ideal routing (low DNS latency)

- Bypass DNS-level censorship (inside a country, from your hotel Internet provider, your school, etc.)

- Being able to identify your device in the logs (if you choose to)

- Hardened Privacy Mode (if you are into that)

Edit: this goes for all our apps (iOS/Android/macOS/Windows/Router client), not just macOS.
