# Requirements

Check your Mac, iPhone or iPad, PC, display and network before installing.

Choose a Mac, iPhone or iPad to play from your Sunshine PC. The PC runs the game; Glimmer sends your controls and brings back the picture and sound.

| Network        | A reachable PC; start on the same network.                                                            |

{% hint style="info" %}
Intel Macs and NVIDIA GameStream are unsupported. HDR, codecs and frame rates need compatible hardware. Glimmer does not install PC display drivers. For Tailscale, enter the PC's address; [pair securely](/docs/security-and-privacy/security.md#pairing).
{% endhint %}

For iPhone and iPad, install the [mobile display modes](/docs/introduction/getting_started/host_setup.md#pick-your-file) on the PC. Native selects from those listed modes, including portrait, Split View and Stage Manager sizes. Touch controls work without a controller.

HEVC and AV1 on iPhone and iPad require hardware decoding support. HDR needs a compatible PC and HDR display; unsupported formats fall back to a supported format. See [display and video choices](/docs/guides/features/streaming.md).
