# Steam Frame ↔ Mac
<div align="center">
**Frame Control** is a Mac app for managing a Valve Steam Frame (standalone VR
headset: SteamOS 3, Arch-based, arm64, Snapdragon 8 Gen 3) over SSH: live
headset view, battery and status, your Steam library, Android (Lepton) apps,
file and clipboard transfer. This repo also holds the scripts behind it and
field notes on how the Frame's software works, all aimed at as little typing
on the headset's virtual keyboard as possible.
<img src="docs/img/icon.png" width="112" alt="Frame Control icon">
It's an unofficial hobby project, not affiliated with Valve.
# Frame Control
Status: written 2026-09-25 and checked against a real Frame the same day
(SteamOS 0.3.0, variant `vr`, build 20260922). The **Frame Control** Mac app
and most scripts are **verified** on the device. The scripts table below marks
each one, and [docs/open-questions.md](docs/open-questions.md#verified-on-device-2026-09-25)
lists what's still unchecked.
**Manage your Valve Steam Frame from your computer.**<br>
See what the headset sees, install games and Android apps, move files and text across, and check battery and status, all over SSH.
## Trying it out
[![Latest release](https://img.shields.io/github/v/release/saphid/steam-frame?label=release&color=1a9fff)](https://github.com/saphid/steam-frame/releases/latest)
[![Platforms](https://img.shields.io/badge/macOS%20%7C%20Windows%20%7C%20Linux-2a475e?label=runs%20on)](#install)
[![Checks](https://img.shields.io/github/actions/workflow/status/saphid/steam-frame/checks.yml?branch=main&label=checks)](https://github.com/saphid/steam-frame/actions/workflows/checks.yml)
[![License: MIT](https://img.shields.io/badge/license-MIT-66c0f4)](LICENSE)
You need:
[**Download**](#install) · [Features](#features) · [Set up the headset](#set-up-the-headset) · [Feedback](#feedback) · [Docs](#going-further)
- A Steam Frame with **Developer Mode** on (next section; it's a toggle).
- A Mac with Apple Silicon (M1 or later). Tested on macOS 26. There's no Intel
build.
- `python3` on the Mac (`xcode-select --install` provides it).
- Optional: `adb` for Android apps (`brew install android-platform-tools`).
<br>
Steps:
<img src="docs/img/frame-control.png" alt="Frame Control showing the headset view, battery and status, and the Steam library" width="900">
1. Download the DMG from the
[latest release](https://github.com/saphid/steam-frame/releases/latest),
open it and drag **Frame Control** to Applications.
2. The app isn't notarized (no paid Apple developer account), so macOS will
say it's damaged or can't be checked. Clear the download quarantine once:
```sh
xattr -dr com.apple.quarantine "/Applications/Frame Control.app"
```
3. Open it. With no `frame` SSH alias yet, it offers to run the connection
setup in Terminal. That asks for the Developer Mode password once, then
uses a key from then on.
<sub>Unofficial hobby project, not affiliated with Valve. Free and open source.</sub>
**Feedback:** please open a
[GitHub issue](https://github.com/saphid/steam-frame/issues) with what you
tried, your SteamOS build (Steam Settings → System) and the server log
(**Frame → Show Server Log**, at `~/Library/Logs/Frame Control/server.log`).
Features are marked **verified** or not below; the unverified ones are the
most useful to hear about.
</div>
**What it changes on your Frame:** only what you click. Installs go to your
user account (`--user` Flatpaks, Lepton instances, Steam downloads), and
nothing needs `sudo` except the power buttons. On the Mac it adds a `Host
frame` entry to `~/.ssh/config` and a key at `~/.ssh/id_ed25519_frame`.
---
## Minimum typing on the headset
## Features
Valve's own developer docs say SSH, ADB, and RDP are all turned on through a
**UI toggle**. You don't need a terminal, `passwd`, or `systemctl`. The only
thing you type on the headset is a password you choose.

<td width="50%" valign="top">
On the Frame:
**👓 Headset view**<br>
Live video of what the lenses show (about 30 fps), or a still of both eyes. Zoom, pan, full screen, save as PNG.
1. **Steam Settings → System → Enable Developer Mode** (a toggle, no typing).
2. Scroll down to the **Developer** section and click **Set User Password**.
Type a password. **This is the only thing you type on the headset.** Pick
something short, because you'll type it once more on the Mac and then
never again.
3. (Optional, no typing) Note the IP address from **Quick Settings** or
**Steam Settings → Internet**, in case `frame.local` doesn't resolve.
4. (Optional) Check **Steam Settings → System → Hostname**. Leaving it as
`frame` means the scripts work without any extra setup.

**🎮 Steam games**<br>
Everything you own with its Steam Frame rating. Install onto the headset with live progress, and search the store.
`connect.sh` does four things:
</td>
<td valign="top">
- finds the headset (`frame.local`, then `frame`, or the IP/host you pass in)
- creates a dedicated key (`~/.ssh/id_ed25519_frame`)
- adds a `Host frame` block to `~/.ssh/config`
- runs `ssh-copy-id`, which asks for the Developer Mode password once
**🤖 Android apps**<br>
About 4,500 F-Droid apps rated for the Frame. One click installs each as its own app in your Steam library.
Run `./scripts/connect.sh --harden` later if you want to turn off SSH password
logins.

**📁 Files and clipboard**<br>
Drag files onto the window to send them. Send text or your clipboard straight to the headset's desktop.
**Fallback, only if the Developer Mode toggle doesn't give you SSH.** From the
Mac, run `./scripts/serve-bootstrap.sh`. It prints a one-liner of about 30
characters, like `curl -fsS mac.local:8765|bash`, to type into Konsole on the
Frame's Linux desktop. The script it serves installs your Mac's public key and
enables `sshd`. See [docs/ssh.md](docs/ssh.md#fallback-bootstrap-one-liner).

Nothing is installed on the Frame for any of this: the app uses what SteamOS

## Install
| | Download | Needs |
|---|---|---|
| Shell on the Frame | `ssh frame` (user `steamos`) | Confirmed (Valve docs) |
| **See/control the Frame from the Mac** | **Steam Link for macOS → connect to `frame`** (Valve names this). Alternatives: RDP to `xrdp` with Microsoft *Windows App* for the Linux desktop, or `adb`/`scrcpy` for the Android (Lepton) layer only | Steam Link and xrdp confirmed on Frame; the Mac RDP client is inferred |
| **Show the Mac's desktop inside the Frame** | **macOS Screen Sharing (built-in VNC) → Remmina (Flatpak, aarch64) on the Frame's Linux desktop**, installed over SSH | Inferred: each piece is documented, but the combination hasn't been tested on a Frame |
| File transfer | `scp` / `rsync` over the `frame` alias (`scripts/push.sh`) | **Verified** (rsync is on the image) |
| Paste Mac clipboard into the headset | `scripts/paste-to-frame.sh` (`pbpaste` → `ssh` → Klipper over D-Bus), or the clipboard sync in an RDP session | **Verified** (script); RDP untested |
| **macOS** (Apple Silicon) | [Frame-Control-mac-arm64.dmg](https://github.com/saphid/steam-frame/releases/latest/download/Frame-Control-mac-arm64.dmg) | Python 3 (`xcode-select --install`) |

Windows `winget install Google.PlatformTools` · Linux `sudo apt install adb`).
## Windows anywhere in the room
<details>
<summary><b>macOS: the app isn't notarized</b></summary>
The in-headset Linux desktop is a single 1280×800 panel, and its windows can't
leave it. Each Steam app, though, gets its own SteamVR panel. That also works
for any Linux app tagged with an app id of its own:
There's no paid Apple developer account behind it, so macOS says the app is
damaged or can't be checked. Drag it to Applications, then clear the download
quarantine once:
```sh
./scripts/panel-on-frame.sh konsole
./scripts/panel-on-frame.sh mac-screen # the Mac's screen, in its own panel
xattr -dr com.apple.quarantine "/Applications/Frame Control.app"
```
Then use the SteamVR dashboard's **Float in World**, **Move** and **Size**
controls to place each panel. See [docs/panels.md](docs/panels.md).
The first time, macOS also asks to allow local network access (for SSH) and
control of Terminal (for the password prompts).
</details>
## Frame Control (Mac app)
<details>
<summary><b>Windows: SmartScreen warning</b></summary>
As of 2026-09-25 no other Mac app manages the Frame end to end.
[Stream Frame](https://streamframe.app/) (macOS 14+, free) records and screenshots
the headset over SSH. [FrameDrop](https://framedropvr.com) sideloads but is
Windows-only. Steam Link views the headset. **Frame Control** is a Mac app over
the scripts below. Install it from the DMG (see [Mac app](#mac-app)), or run
the same UI in a browser without packaging:
The installer isn't code-signed, so Windows SmartScreen may say it protected
your PC. Choose **More info → Run anyway**. The portable `.zip` avoids the
installer: unzip it anywhere and run `Frame Control.exe`.
</details>
<details>
<summary><b>Linux: running the AppImage</b></summary>
```sh
./scripts/frame-ui.sh # opens http://127.0.0.1:47810 in its own window
chmod +x Frame-Control-linux-*.AppImage && ./Frame-Control-linux-*.AppImage
```
![Frame Control](docs/img/frame-control.png)
If it complains about FUSE, install `libfuse2` (Ubuntu 24.04+: `libfuse2t64`),
or run it with `--appimage-extract-and-run`. Sending the clipboard needs
`wl-clipboard` (Wayland) or `xclip` (X11).
</details>
- **Headset view**: what the lenses show, as SteamVR composites it (the room,
floating panels, dashboard and controllers). Shows the left eye, like pointing
a camera into one lens, or both eyes, as a single shot; saves as PNG. **Live**
is 720p video at about 30 fps: `ffmpeg` on the Frame encodes SteamVR's
headset-view device (`/dev/video99`) to H.264 over SSH, and the page decodes
it with WebCodecs. Live video is one eye; Capture still gets both. The viewer fits the whole frame; zoom with − / + (or scroll, or
double-click), drag to pan, `0` to fit, `F` for full screen. Capture uses OpenVR's `IVRScreenshots` API through Python `ctypes`
(`ui/frame_vrshot.py`). Nothing extra is installed on the Frame (SteamOS ships `ffmpeg`). **Desktop panel**
captures gamescope's flat layer instead.
- Battery with charging state: charge rate in watts, time to full or empty,
charger type and wattage (for example USB-C PD 20 W), and battery temperature
- Storage, memory, temperature, Wi-Fi, uptime, and whether SteamVR, the desktop,
Lepton and xrdp are running
- Library shelf with Steam cover art and a Play button (`steam://rungameid`)
- **Get games**: every game you own with its Steam Frame rating (Verified,
Playable, Unsupported, Unknown). Install on Frame downloads it to the headset
with live progress. Search the Steam store with prices and Frame ratings; Buy
opens the store page in your browser, or Store on Frame opens it in the
headset. It drives the Frame's own Steam client through its DevTools port;
see `docs/steam-games.md`
- Volume and mute (`wpctl`)
- **Android apps**: search about 4,500 F-Droid apps rated for the Frame, install
one with a click as its own Lepton instance (it keeps its data and shows in the
Steam library), then launch, stop, test or remove it. **Report an APK** records whether any APK
worked (F-Droid or not: pick a file, type a package, or use an installed app). Your
reports are saved on your Mac and change the verdicts you see. They aren't
uploaded anywhere: the shared database is maintainer-only for now (see
`compat-db/README.md`)
- **Android display**: pick a running Lepton instance (by the app in it) and set
its resolution (Native 1920×1080, or Sharp 2560×1440 with density scaled to
match), UI scale (Smaller / Default / Larger, or an exact dpi) and text size
(0.85–1.3×) over ADB (`wm size`, `wm density`, `font_scale`). Reset puts all three
back. Whether the settings survive the app relaunching is untested
- Drag and drop files to `~/Downloads`; `.apk` files install as their own Android app
- Send typed text, or the Mac clipboard, to the Frame clipboard
- Install and remove Flatpaks (quick picks: Moonlight, Firefox, VLC, Remmina)
- One-click SSH or SFTP in Terminal, Steam Link, and Windows App (RDP).
Sleep, restart and shut down open Terminal because SteamOS asks for the
sudo password over SSH.
## Set up the headset
The server is Python stdlib only and listens on 127.0.0.1. It rejects requests
with a non-local `Host` header, and any `/api/` request without a custom
header, so other websites can't drive it or read captures. It keeps a single multiplexed SSH connection open, so
status and each capture take about 0.3s. Headset captures are deleted from the
Frame as soon as they're copied, because they show everything on screen,
including anything private. The look follows the Steam client: its palette,
Motiva Sans (loaded from Valve's CDN), portrait library capsules and green
Play buttons. **Verified on the Frame 2026-09-25:** status and charging details,
both capture modes (headset view while in use, and a blank frame in standby,
which the UI labels), clipboard, volume, file push, and input validation. **Not yet exercised from the UI:** Launch, Flatpak
install/remove, APK drop, and the power buttons. Each of these calls a
command or script that was verified separately.
You type one password on the headset, once. Everything else happens on your
computer.
### Mac app
1. **On the Frame:** Steam Settings → System → **Enable Developer Mode**, then
in the Developer section, **Set User Password**. Pick something short:
you'll type it once more on your computer and then never again.
2. **On your computer:** open Frame Control. It offers to **Set Up
Connection**, which finds the headset, creates an SSH key, and asks for that
password once in a terminal window. If it can't find the Frame, type the
IP address from the Frame's Quick Settings.
3. That's it. The app now reaches the headset whenever it's awake and on the
same network. For anywhere else, see [Tailscale](docs/tailscale.md).
`app/` wraps the same UI as a standalone Mac app (Electron). The app bundles
`ui/`, `scripts/`, `frame/android/` and the rated catalogue from `apk-catalog/`.
It starts `ui/server.py` on a free loopback port and shows it in its own window.
The server stops when you quit the app. A prebuilt DMG for Apple Silicon is
attached to each [GitHub release](https://github.com/saphid/steam-frame/releases).
**What it changes:** only what you click. Installs go to your user account on
the Frame (`--user` Flatpaks, Lepton instances, Steam downloads), and nothing
needs `sudo` except the power buttons. On your computer it adds a `Host frame`
entry to `~/.ssh/config` and a key at `~/.ssh/id_ed25519_frame`.
```sh
cd app
npm install
npm run dist # → app/dist/Frame Control-<version>-arm64.dmg (and a .zip)
npm start # run from the checkout without packaging
```
## Feedback
Open the DMG and drag **Frame Control** to Applications. You need `python3` on
the Mac (Xcode Command Line Tools or Homebrew). The app reads `PATH` from your
login shell, so Homebrew's `rsync` and `adb` work when you launch it from
Finder. Each time it starts while there's no `frame` SSH alias, the app offers
to run `connect.sh` in Terminal. **Frame → Set Up Connection…** does the same
at any time. The Frame menu also shows the server log at
`~/Library/Logs/Frame Control/server.log`. Installing APKs needs `adb`
(`brew install android-platform-tools`). The F-Droid ratings are bundled with the app.
This is a first public test, so reports are really useful, especially from
Windows and Linux. Please [open an issue](https://github.com/saphid/steam-frame/issues/new)
with:
The build is ad-hoc signed and not notarized. A copy you build yourself opens
normally. A copy downloaded from GitHub Releases is quarantined; clear it with
`xattr -dr com.apple.quarantine "/Applications/Frame Control.app"`. The first
time you use them, macOS asks to allow local network access (for SSH) and
control of Terminal (for SSH and power actions). **Verified 2026-09-25:**
installed from the DMG, launched from Finder, connected to the Frame, and
showed live status and the library.

python3 -m unittest discover -s tests # server guards, validation, Steam helpers; no headset needed
cd app && npm install && npm run dist # build the DMG
python3 -m unittest discover -s tests # server tests; no headset needed
cd app && npm install && npm start # run the app from the checkout
```
GitHub Actions runs the tests on Python 3.9, which is the oldest `python3` the app
may find (Xcode Command Line Tools), plus syntax checks for every script and the
Electron main process (`.github/workflows/checks.yml`). Anything that touches the
headset is verified by hand against a real Frame, and the docs label it
**verified** or **inferred**.
The server is Python stdlib only; the app is Electron. GitHub Actions runs the
tests on macOS, Windows and Linux, and a `v*` tag builds all three installers
into the release. See [building](docs/frame-control.md#building).

# Frame Control in detail
What each part of the app does, how it works, and what has been checked on a
real Frame. For installing it, see the [README](../README.md#install).
As of 2026-09-25 no other desktop app manages the Frame end to end.
[Stream Frame](https://streamframe.app/) (macOS 14+, free) records and screenshots
the headset over SSH. [FrameDrop](https://framedropvr.com) sideloads but is
Windows-only. Steam Link views the headset.
You can also run the same UI in a browser without the app, from a checkout:
```sh
./scripts/frame-ui.sh # macOS: opens http://127.0.0.1:47810 in its own window
python3 ui/server.py # anywhere: then open http://127.0.0.1:47810
```
## Features
- **Headset view**: what the lenses show, as SteamVR composites it (the room,
floating panels, dashboard and controllers). Shows the left eye, like pointing
a camera into one lens, or both eyes, as a single shot; saves as PNG. **Live**
is 720p video at about 30 fps: `ffmpeg` on the Frame encodes SteamVR's
headset-view device (`/dev/video99`) to H.264 over SSH, and the page decodes
it with WebCodecs. Live video is one eye; Capture still gets both. The viewer
fits the whole frame; zoom with − / + (or scroll, or double-click), drag to
pan, `0` to fit, `F` for full screen. Capture uses OpenVR's `IVRScreenshots`
API through Python `ctypes` (`ui/frame_vrshot.py`). Nothing extra is
installed on the Frame (SteamOS ships `ffmpeg`). **Desktop panel** captures
gamescope's flat layer instead.
- **Screenshots** you take in the headset with Steam's shortcut: browse them and
save them to `~/Pictures/SteamFrame`.
- **Battery** with charging state: charge rate in watts, time to full or empty,
charger type and wattage (for example USB-C PD 20 W), and battery temperature.
- **Status**: storage, memory, temperature, Wi-Fi, uptime, and whether SteamVR,
the desktop, Lepton and xrdp are running.
- **Library** shelf with Steam cover art and a Play button (`steam://rungameid`).
- **Get games**: every game you own with its Steam Frame rating (Verified,
Playable, Unsupported, Unknown). Install on Frame downloads it to the headset
with live progress. Search the Steam store with prices and Frame ratings; Buy
opens the store page in your browser, or Store on Frame opens it in the
headset. It drives the Frame's own Steam client through its DevTools port;
see [steam-games.md](steam-games.md).
- **Volume** and mute (`wpctl`).
- **Android apps**: search about 4,500 F-Droid apps rated for the Frame, install
one with a click as its own Lepton instance (it keeps its data and shows in the
Steam library), then launch, stop, test or remove it. **Report an APK** records
whether any APK worked (F-Droid or not: pick a file, type a package, or use an
installed app). Your reports are saved on your computer and change the verdicts
you see. They aren't uploaded anywhere: the shared database is maintainer-only
for now (see [compat-db/README.md](../compat-db/README.md)). Needs `adb`, and
`aapt2` for reading APK files.
- **Android display**: pick a running Lepton instance (by the app in it) and set
its resolution (Native 1920×1080, or Sharp 2560×1440 with density scaled to
match), UI scale (Smaller / Default / Larger, or an exact dpi) and text size
(0.85–1.3×) over ADB (`wm size`, `wm density`, `font_scale`). Reset puts all
three back. Whether the settings survive the app relaunching is untested.
- **Transfer**: drag and drop files to `~/Downloads`; `.apk` files install as
their own Android app. Send typed text, or your computer's clipboard, to the
Frame clipboard.
- **Flatpaks**: install and remove them (quick picks: Moonlight, Firefox, VLC,
Remmina).
- **One-click tools**: SSH or SFTP in a terminal window, Steam Link, and remote
desktop (Windows App on macOS, Remote Desktop on Windows, Remmina or FreeRDP on
Linux). Sleep, restart and shut down open a terminal window because SteamOS
asks for the sudo password over SSH.
## How it works
`app/` is an Electron shell. It starts `ui/server.py` on a free loopback port
and shows it in its own window; the server stops when you quit the app. The
app bundles `ui/`, `scripts/`, `frame/android/` and the rated catalogue from
`apk-catalog/`, and on Windows an embedded Python too.
The server is Python stdlib only and listens on 127.0.0.1. It rejects requests
with a non-local `Host` header, and any `/api/` request without a custom
header, so other websites can't drive it or read captures. Everything reaches
the headset through the `frame` SSH alias. On macOS and Linux it keeps one
multiplexed SSH connection open, so status and each capture take about 0.3 s.
Windows' OpenSSH can't share a connection, so there each request connects on
its own and the app is a little slower. What differs between the three
systems lives in `ui/frame_host.py`.
Headset captures are deleted from the Frame as soon as they're copied, because
they show everything on screen, including anything private. The look follows
the Steam client: its palette, Motiva Sans (loaded from Valve's CDN), portrait
library capsules and green Play buttons.
**Verified on the Frame 2026-09-25 (macOS app):** status and charging details,
both capture modes (headset view while in use, and a blank frame in standby,
which the UI labels), clipboard, volume, file push, and input validation.
**Not yet exercised from the UI:** Launch, Flatpak install/remove, APK drop,
and the power buttons. Each of these calls a command that was verified
separately.
## Per-platform notes
**macOS.** The app reads `PATH` from your login shell, so Homebrew's `rsync`,
`adb` and Python work when you launch it from Finder. Set Up Connection runs
`scripts/connect.sh` in Terminal. The log is at
`~/Library/Logs/Frame Control/server.log`. The build is ad-hoc signed and not
notarized: a downloaded copy is quarantined until you run
`xattr -dr com.apple.quarantine "/Applications/Frame Control.app"`. The first
time you use them, macOS asks to allow local network access (for SSH) and
control of Terminal (for SSH and power actions).
**Windows.** Python is bundled; `ssh` is Windows' built-in OpenSSH client
(Settings → System → Optional features, if it's been removed). Set Up
Connection runs `ui/frame_connect.py` in a console window. Copies use `scp`
because Windows has no `rsync`. The installer isn't code-signed, so SmartScreen
warns on first run: choose **More info → Run anyway**. The log is at
`%APPDATA%\Frame Control\logs\server.log`.
**Linux.** Needs `python3` (3.8 or later) and `ssh`, which most desktops
have. The AppImage runs anywhere; the `.deb` pulls both in on Debian and
Ubuntu. Set Up Connection runs `ui/frame_connect.py` in your terminal emulator
(GNOME Terminal, Konsole, xterm and others). Sending the clipboard needs
`wl-clipboard` (Wayland) or `xclip` (X11). The log is at
`~/.config/Frame Control/logs/server.log`.

# Scripts and headset setup
The command-line side of this repo: how SSH gets set up with as little typing on
the headset as possible, what to use for each job, and the helper scripts that
Frame Control is built on. The scripts are zsh/bash and run on macOS; most also
run on Linux. On Windows, use the app.
## Minimum typing on the headset
Valve's own developer docs say SSH, ADB, and RDP are all turned on through a
**UI toggle**. You don't need a terminal, `passwd`, or `systemctl`. The only
thing you type on the headset is a password you choose.
On the Frame:
1. **Steam Settings → System → Enable Developer Mode** (a toggle, no typing).
2. Scroll down to the **Developer** section and click **Set User Password**.
Type a password. **This is the only thing you type on the headset.** Pick
something short, because you'll type it once more on the Mac and then
never again.
3. (Optional, no typing) Note the IP address from **Quick Settings** or
**Steam Settings → Internet**, in case `frame.local` doesn't resolve.
4. (Optional) Check **Steam Settings → System → Hostname**. Leaving it as
`frame` means the scripts work without any extra setup.
On the Mac:
To use the scripts from a checkout instead of the app:
```sh
git clone https://github.com/saphid/steam-frame.git && cd steam-frame
./scripts/connect.sh # or: ./scripts/connect.sh 192.168.1.50
ssh frame # passwordless from now on
```
`connect.sh` does four things:
- finds the headset (`frame.local`, then `frame`, or the IP/host you pass in)
- creates a dedicated key (`~/.ssh/id_ed25519_frame`)
- adds a `Host frame` block to `~/.ssh/config`
- runs `ssh-copy-id`, which asks for the Developer Mode password once
Run `./scripts/connect.sh --harden` later if you want to turn off SSH password
logins.
Sources: [Valve: Setting up your Steam Frame for development](https://partner.steamgames.com/doc/steamhardware/steamframe/setup),
[Valve: Steam Frame Debugging](https://partner.steamgames.com/doc/steamhardware/steamframe/debugging)
(both **confirmed on Steam Frame**, Valve official).
**Fallback, only if the Developer Mode toggle doesn't give you SSH.** From the
Mac, run `./scripts/serve-bootstrap.sh`. It prints a one-liner of about 30
characters, like `curl -fsS mac.local:8765|bash`, to type into Konsole on the
Frame's Linux desktop. The script it serves installs your Mac's public key and
enables `sshd`. See [docs/ssh.md](ssh.md#fallback-bootstrap-one-liner).
## Recommended options
| Goal | Recommended | Confidence |
|---|---|---|
| Shell on the Frame | `ssh frame` (user `steamos`) | Confirmed (Valve docs) |
| **See/control the Frame from the Mac** | **Steam Link for macOS → connect to `frame`** (Valve names this). Alternatives: RDP to `xrdp` with Microsoft *Windows App* for the Linux desktop, or `adb`/`scrcpy` for the Android (Lepton) layer only | Steam Link and xrdp confirmed on Frame; the Mac RDP client is inferred |
| **Show the Mac's desktop inside the Frame** | **macOS Screen Sharing (built-in VNC) → Remmina (Flatpak, aarch64) on the Frame's Linux desktop**, installed over SSH | Inferred: each piece is documented, but the combination hasn't been tested on a Frame |
| File transfer | `scp` / `rsync` over the `frame` alias (`scripts/push.sh`) | **Verified** (rsync is on the image) |
| Paste Mac clipboard into the headset | `scripts/paste-to-frame.sh` (`pbpaste` → `ssh` → Klipper over D-Bus), or the clipboard sync in an RDP session | **Verified** (script); RDP untested |
Details: [docs/ssh.md](ssh.md), [docs/streaming.md](streaming.md),
[docs/file-transfer.md](file-transfer.md),
[docs/open-questions.md](open-questions.md). For how the Frame's software
fits together, see [docs/how-the-frame-works.md](how-the-frame-works.md).
## Windows anywhere in the room
The in-headset Linux desktop is a single 1280×800 panel, and its windows can't
leave it. Each Steam app, though, gets its own SteamVR panel. That also works
for any Linux app tagged with an app id of its own:
```sh
./scripts/panel-on-frame.sh konsole
./scripts/panel-on-frame.sh mac-screen # the Mac's screen, in its own panel
```
Then use the SteamVR dashboard's **Float in World**, **Move** and **Size**
controls to place each panel. See [docs/panels.md](panels.md).
## Scripts
| Script | Runs on | Purpose |
|---|---|---|
| `scripts/tailscale-on-frame.sh` | Mac → Frame | Install Tailscale in `~` as a userspace user service so `frame` works from anywhere; `--uninstall` (**verified** on the LAN) |
| `scripts/connect.sh` | Mac | Discover, set up key and `~/.ssh/config`, copy key, optional `--harden` (**verified**; `--harden` untested) |
| `scripts/install-apps.sh` | Mac → Frame | Install Flatpaks (Remmina, Moonlight, …) on the Frame over SSH as `--user` (**verified** with Remmina) |
| `scripts/paste-to-frame.sh` | Mac → Frame | Send the Mac clipboard (or stdin) to the Frame clipboard (**verified**) |
| `scripts/install-apk.sh` | Mac → Frame | Install APKs, each as its own persistent Lepton instance with a Steam library shortcut (`--dev`: old ADB path into Lepton Development) (**verified**; see [docs/apks.md](apks.md)) |
| `scripts/panel-on-frame.sh` | Mac → Frame | Start an app as its own floating VR panel, outside the desktop (**verified**: overlays created; in-headset placement not yet checked) |
| `scripts/run-on-frame.sh` | Mac → Frame | Start an app on the headset desktop, e.g. `mac-screen` opens Remmina straight into the Mac (**verified**) |
| `scripts/frame-ui.sh` | Mac | Start the Frame Control web UI (`ui/server.py`) and open it (**verified**) |
| `scripts/apk-catalog.sh` | Mac | Refresh the rated F-Droid catalogue that Frame Control's Android section shows (**verified**) |
| `scripts/compat-db-backup.sh` | Mac | Maintainer-only: back up the shared compatibility database locally and to Google Drive (**verified**) |
| `scripts/push-vr-video.sh` | Mac → Frame | Upload VR180/360 videos to `~/Videos/VR`, linked into DeoVR's Proton prefix; `--launch` starts DeoVR (**verified**: upload and link; in-headset playback of local files not yet checked). See [docs/vr-video.md](vr-video.md) |
| `scripts/push.sh` | Mac → Frame | `rsync` files to `~/Downloads` (or a given path) on the Frame (**verified**) |
| `scripts/serve-bootstrap.sh` | Mac | Fallback: serve `bootstrap-on-frame.sh` with your public key embedded |
| `scripts/bootstrap-on-frame.sh` | Frame | Fallback: install the key and enable `sshd` |
