To use one wireless mouse on two computers, you have four documented methods: a KVM switch, a USB switch, Bluetooth pairing on each computer, or software that shares input across devices. The clearest documented software option is Microsoft's Mouse without Borders for up to four Windows computers, while Apple documents mouse pairing on iPhone through AssistiveTouch.
How to use one wireless mouse on two computers: Overview of the four methods
One mouse, two computers means either switching the mouse's connection between devices or sharing input with hardware or software. If you need a hardware solution and do not mind that exact setup steps vary by model, a KVM or USB switch works. For a software-based approach with documented support, Mouse without Borders is the clearest option for Windows users.
Use a software solution like Mouse without Borders
Microsoft's Mouse without Borders lets you control up to four computers from a single mouse and keyboard. After installing the software on each Windows computer and connecting them to the same network, you can move between them by moving the mouse cursor beyond the edge of the screen. This also allows you to drag and drop files between PCs. Synergy software supports Windows, macOS, and Linux for sharing one mouse across multiple computers. ShareMouse software offers clipboard sharing, file transfer capabilities, and cross-platform support between Windows and macOS. Input Director software supports multi-monitor setups and is compatible with Windows systems. Barrier is an open-source software option with cross-platform compatibility for Windows, macOS, and Linux.
Pair via Bluetooth on each computer
To use Bluetooth, put your wireless mouse in pairing mode and connect it to each computer individually. For iPhone, Apple documents the path through Settings > Accessibility > Touch > AssistiveTouch > Devices > Bluetooth Devices, then select the device from the list. Apple also states you can plug in a wired mouse, trackpad, or Bluetooth device using a Lightning or USB-C port, and if you use USB-A devices, you need an adapter. For Android, no official manufacturer support page was retrieved that documents a built-in equivalent for sharing one mouse across two computers. Note that Bluetooth connectivity range is typically limited to about 30 feet; keep computers within close proximity to avoid signal loss. An Apple discussion thread says Magic Mouse 2 is not supported on iPhone.
Use a KVM or USB switch for hardware switching
In general, both methods involve connecting the mouse receiver to the switch and using a button or hotkey to toggle between computers. KVM switches support hotkey switching using specific key combinations on the keyboard. When using a KVM switch, both computers should have compatible USB ports and the switch should support USB passthrough. USB switches can support additional USB devices like keyboards or external hard drives, allowing switching of all peripherals between computers. If you use laptop docking stations, a KVM or USB switch can integrate with them to manage multiple peripherals across computers.
What to consider when choosing a method
Consider operating system compatibility: Mouse without Borders works on Windows only, while Bluetooth pairing works on any device with Bluetooth, including iPhone via AssistiveTouch. Consider the number of computers: Mouse without Borders supports up to four, while hardware switches can support more depending on the model. If you need file sharing between computers, Mouse without Borders supports drag-and-drop, whereas Bluetooth and hardware switches do not. If phones are involved, Apple documents mouse pairing on iPhone through AssistiveTouch, but no official Android equivalent was retrieved.
Frequently Asked Questions
Can one wireless mouse be used on two computers?
Yes, if the mouse can switch pairings, if it is connected through a KVM or USB switch, or if software such as Mouse without Borders is used on supported computers.
What is the iPhone path to pair a mouse?
Does Microsoft Mouse without Borders work on Mac or Linux?
The retrieved Microsoft documentation is for Windows computers only; no official support for Mac or Linux was documented in the gathered pages.
Can I use a dual-mode mouse to control two computers?
Yes, dual-mode mice are designed to work with multiple devices simultaneously, using either Bluetooth or a wireless USB receiver. You switch between modes to control each computer.
