Work in separate apps on two computers
Use input sharing when a Mac runs your documents and a Windows computer runs another application. Each machine renders its own screen while you move the keyboard and mouse between them.
Keep your MacBook and Windows computer running their own apps while using one keyboard and mouse. Any Display’s Share keyboard & mouse mode moves input between the two computers at a chosen screen edge. Each computer keeps its own display; this mode does not stream video.
Install the desktop app on each Mac or Windows computer and connect them to the same local network. Keep both awake. A tablet companion app is not needed for sharing input between computers.
Start on the computer with the keyboard and mouse you want to use. Open Share keyboard & mouse, select the other computer and check which machine will supply input. Send the request and accept it on the other computer after checking its identity.
Choose left, right, top or bottom according to where the other screen sits. With several monitors, select the switching monitor as well. Changing the edge or switching monitor requires reconnecting for the new layout to take effect.
If macOS requests Accessibility permission, allow Any Display. In Advanced, review modifier mappings when moving between Mac and Windows. If input-language switching behaves differently, check the language-switch key and test in a text editor.
Move across the chosen monitor edge and type into a blank document on the other computer. Test copying plain text too. Use Ctrl+Alt+Shift+Esc if you need to force control back locally. End the session from Share keyboard & mouse when finished.
Use input sharing when a Mac runs your documents and a Windows computer runs another application. Each machine renders its own screen while you move the keyboard and mouse between them.
Choose the separate computer display feature to view or send a screen. Turning on input sharing alone does not make the remote display appear on this computer.
Tablet Extend or Mirror is another connection. It has a different purpose from computer input sharing and does not mean this KVM mode controls native Android or iPad apps.
