Control Android with your Mac’s mouse and keyboard

In Decky Display’s Android settings, find Allow wireless control in the screen-sharing section. Read the disclosure, choose Agree and continue, then enable Decky Display wireless control in Android’s Accessibility settings. Return to Decky Display before starting Control on the Mac. Screen capture is not required for this control session.

Wi-Fi provides a visible pointer, clicks, scrolling, navigation, text entry and supported editing shortcuts. Apps do not receive pointer hover or held keys over this route. Text and shortcut support can vary with the Android version and the focused app. Direct USB provides native mouse and keyboard input instead.

Turn on Switch at screen edges on the device card or in Decky’s Settings → Devices → Control. For a windowed Extend desktop, the Mac’s display arrangement determines where you cross into Decky. With no desktop stream, use the remembered position or choose a Mac screen and side in Control settings.

Move toward the tablet through the corresponding Mac screen edge. Return through the tablet’s outer edge that faces a Mac screen. Crossing an edge inside Android, such as the boundary between Decky and another app, keeps control on the tablet. Held buttons or modifier keys prevent accidental crossings. If two devices use the same edge, choose another side for one.

Put Decky Display in Android split-screen or a window. Start control on the Mac, then move through the tablet workspace. Inside Decky’s Mac picture you control macOS; move into the neighboring Android app to click, scroll and type there.

Automatic entry works with a visible windowed Extend desktop or without a desktop stream. Mirror and Alone use manual control. Fullscreen display temporarily blocks whole-device control. An enabled automatic session becomes ready again when Decky returns to a window, and waits for a new crossing.

Press Esc twice to return to the Mac. A single Esc sends Android Home during device control. The default toggle shortcut is Control+Option+Command+K; change it in Settings → Devices → Control → Shortcut. It returns to the Mac during control and re-enters the last ready Android device afterward.

The Command key setting can make Command act like Ctrl for Android editing shortcuts. This affects input on Android, not shared clipboard contents. The right Command key can serve as Android’s Meta key in that mapping.

Switching to another Android app keeps an already authorized control session ready. Return to Mac releases your mouse and keyboard while leaving the session ready for re-entry. End control ends the session and turns off automatic edge switching. Android’s notification also offers End control.

A lost connection returns input to the Mac. Mac sleep or locking also releases input; automatic sessions can become ready again after waking or unlocking, but wait for a new crossing. To bring a connected Decky Display forward from the Mac, enable Open from Mac in Android’s Decky settings and grant the requested permission. Then use Open on the Mac device card. This does not wake a disconnected or force-stopped app.
