OneScreen for Mac

OneScreen for Mac is a menu bar app that streams a display from your computer to an iPad in real time over your local network. Built for photographers and on-set teams who need live, color-accurate previews during commercial shoots, it pairs the speed of NDI with tight Capture One integration so clients, art directors, and crew can review work as it happens without crowding your workstation.

Streaming built for live shoots. Streams use the NDI protocol for low-latency local-network delivery. Choose between an open NDI source or a private session paired by QR code or passphrase, so trusted devices connect without exposing the stream to the rest of the network. Pick from three bandwidth presets - Best, Balanced, and Low Bandwidth - or define a custom mix of frame rate and resolution for the conditions you are shooting in.

Color-accurate output. Twelve output color spaces are available, including sRGB, Display P3, Adobe RGB (1998), DCI-P3, Rec. 709, Rec. 2020, ROMM RGB, and linear variants. Receiver iPads can also be tuned in real time with brightness and white balance controls so what is on set matches what is on screen.

Virtual iPad displays. OneScreen can spin up an on-demand virtual display sized to current iPad models. Pick Retina for a sharper workspace or Actual Size for a pixel-for-pixel match. Combined with Cursor Lock, the iPad becomes a reliable extension of the Mac with no extra hardware required.

Capture One integration. With Capture One installed, OneScreen exposes remote controls from the iPad: navigate previous and next, rate 0-5 stars, apply color tags, trigger Live View, fire the shutter, and adjust camera settings. Toggle overlay, grid, image rotation, and stream either the main Viewer or the Client Viewer.

Receiver controls. Connected iPads can be renamed, color-labeled, locked, and managed from the menu bar. Save name-and-color presets for quick assignment during fast-moving shoots. A power-save mode dims receivers between setups, and per-receiver alerts surface state changes without interrupting the session.

Intermission, preview, and hotkeys. Pause the stream with an intermission card to cover wardrobe changes or breaks without dropping connections. A floating preview window mirrors what the iPad sees, with keep-on-top, opacity, and auto-hide options. Key actions such as pause, resume, fullscreen, lock, unlock, preview, and power save have assignable hotkeys for keyboard-driven workflows.

Local-first and private. Streams stay on your local network. There is no cloud upload and no account required to stream. A first-run setup sheet walks through the Screen Recording, Local Network, NDI Runtime, and optional Accessibility permissions in one place.
