The Remio handbook, in one place.
Guides, setup steps, system requirements, and the fixes for the things that occasionally go wrong. Written for the question you actually typed.
Three steps to your first session.
Install the host on the Mac you want to reach.
Download the macOS host, grant screen recording and accessibility, and leave it running in the menu bar.
Install the client on the device you will use.
Available for iPhone, iPad, macOS, and Android. Same app icon on every store.
Scan the pairing QR and stream.
Devices on the same network find each other directly. No accounts, no cloud relay for video, AES-256-GCM end to end.
Getting started
Everything you need to go from an empty Mac to streaming it on your iPhone in under five minutes. Start here if Remio is brand new on the device.
Download the host, grant permissions, install the client, scan the QR, stream.
Granting screen recording and accessibilityThe two macOS permissions Remio needs, and why each one is required.
Pairing devices with a PIN or QR codeHow proximity pairing works and what the host actually shows on screen.
System requirements
The minimum hardware and OS versions Remio supports, plus the network conditions needed for a low-latency session. Check here before you install if you are on older hardware.
One canonical reference for macOS, iOS, iPadOS, and the network in between.
macOS host requirementsmacOS 15 Sequoia and later, Apple Silicon preferred, Intel still supported.
iOS and iPadOS client requirementsiOS 18 and later. Universal binary for iPhone and iPad.
Network and bandwidth notesWhat 5 GHz Wi-Fi, wired ethernet, and cellular each look like in practice.
Setup recipes
Step-by-step walkthroughs for the most common device pairings. Each recipe covers permissions, network setup, and the first thing to check when something does not work.
Pair two Macs on the same network or across the internet.
Mac host to iPad clientPencil pressure, hardware keyboard, and Apple Magic Trackpad on iPad.
Windows host to Mac clientReach a Windows desktop from a Mac with full input parity.
Multi-monitor configurationDrive multiple displays from a single client, or mirror one host monitor to many.
Audio, input, and peripherals
Get audio, keyboard, mouse, gamepad, and Apple Pencil working as if the peripheral were plugged into the host directly.
Right-click, scroll, drag, and zoom with your fingers — the full gesture reference for iPhone, iPad, and Android.
Audio routing setupRoute host audio back to your client speakers with low latency.
Audio troubleshootingDiagnose dropouts, crackling, and silent streams across macOS, Windows, and Linux.
Keyboard layout fixesMap non-US layouts, fix sticky modifiers, and rebind problematic keys.
Gamepad and controller setupDualSense, Xbox, and MFi controllers — pairing, haptics, and rumble.
Apple Pencil setupPressure, tilt, and palm rejection on iPad — the desktop-side configuration.
Troubleshooting
When something is off — the stream stalls, audio drops, input feels heavy — the fixes that work are usually network and permission settings. Each guide names the symptom in plain language.
Same network, firewall rules, local network permission, and pairing state.
The stream feels laggyStep-by-step reductions in frame rate, resolution, and codec until it is smooth.
No audio is coming throughmacOS audio routing, the host audio capture toggle, and what to check first.
Keyboard or mouse input is not workingAccessibility permission re-grant, hardware keyboard detection, and trackpad gestures.
Networking and direct connection
Remio prefers a direct device-to-device path between the two endpoints. When that is not possible the session falls back to a relay. This is where to learn how the connection is actually chosen.
How Remio finds the fastest network path, and why most home networks reach a direct connection within seconds.
Firewall and NAT setupPort-forwarding, double NAT, and corporate firewall workarounds.
Dual GPU host setupPick the right encoder when a host has both integrated and discrete GPUs.
Security architecture overviewEnd-to-end encryption, key exchange, and the zero-knowledge connection design.
Security whitepaperThe full cryptographic spec — protocols, ciphers, threat model, and audit notes.
Developers and protocol
Hooks for engineers who want to know what is on the wire. The data channel and connection layer use open, schema-defined binary protocols.
