ShareMouse is a software program for Windows and macOS, that allows you to control multiple computers with a single mouse & keyboard.

ShareMouse also synchronizes your clipboard between computers and enables you to drag & drop files from one to another computer.

ShareMouse creates a virtual desktop sphere of all monitors of any computer on your desk.

The mouse cursor can seamlessly roam from one monitor to any other monitor as if it were one single desktop.

This is similar to a dual monitor setup (two monitors connected to a single PC). With ShareMouse, however, it also works across multiple computersinstead of just multiple monitors.

If the mouse pointer crosses the border of the monitor of one computer it automatically appears on the monitor of another computer located next to each other.

In this case, all cursor movements and keyboard input is transmitted using your existing network connection.

The ShareMouse Standard Edition supports exactly one display per computer.

The Professional Edition supports a maximum of four monitors per computer, but probably a maximum of 26 monitors in total.

Unfortunately, we are not able to state the maximum number of supported displays as we do not have so many monitors in our labs. Please test the free demo version for compatibility with your individual setup.

The ShareMouse version available on the download page allows you to try all features for 20-30 minutes. For another evaluation period, simply restart all ShareMouse clients and you get another 30 minutes trial period.

Please test everything thoroughly and if you are happy with the results, the registration of a purchased license key turns the demo version into a full version. There is no need to install any other/different software.

We don't offer a typical "30 day trial version" as ShareMouse does not include any feature, that requires an evaluation over such an extended time period. Testing the remote control feature requires a simple swipe with the mouse. Drag & Drop would take the same time. Trying the copy & remote paste feature is a matter of seconds.

ShareMouse should work fine on any modern Windows PC or Apple Mac.

Due to the large number of possible system environments we cannot make a compatibility statement for a specific system configuration. Please test the free demo version to make sure, that everything works fine in your individual setup and network environment.

ShareMouse is a smart alternative to hardware KVM switches because it does not require extra cables and offers features that are not available with a hardware KVM, such as drag & drop of files between computers or transfer of the clipboard.

No, each computer requires at least one monitor.

There is ultimately no use for ShareMouse if any of your computers is not connected to a dedicated monitor. ShareMouse is not a Remote Desktop Software such as TeamViewer or VNC.

Yes, you can use ShareMouse with any combination of Windows PCs and Apple Macs.

Computers can be any mix of Laptops, Netbooks, Desktop or Tablet PCs (mouse device required, a stylus would not work with ShareMouse).

No, ShareMouse is not compatible with Android or Apple iPhone/iPad and we do not have plans for it at this time.

No, ShareMouse is not Linux-compatible and we do not have plans for it at this time.

ShareMouse and VNC serve a totally different purpose: VNC transmits a remote PC's monitor contents onto your local computer monitor via the network/internet. This is also called "Remote Desktop Access".

ShareMouse, instead, does not transmit the monitor contents of any remote computer. It rather sends the mouse/keyboard input from one to another local computer to allow you to control that PC while you look at the monitor of that PC.

You can also transfer files between computers using drag & drop and transmit the clipboard.

ShareMouse uses your existing local network connection to transmit the mouse cursor movements and keyboard input between the computers. It also uses the network to support file drag & drop and clipboard transfer.

ShareMouse requires internet access during the short time of license registration and if you enabled the automatic check for software updates. Other than that, ShareMouse does not need an internet connection and you can lock it up in your outbound firewall.

ShareMouse uses the local network connection to transmit the mouse cursor movements and keyboard input which may trigger a firewall warn. You must grant ShareMouse access to the local network.

ShareMouse also requires internet access during the short time of license registration and if you opted for the automatic check for software updates. Other than that, you can safely lock ShareMouse up from outbound internet traffic in your firewall.

A properly configured VPN connection may work with limited transmission performance compared to a local network connection.

However, due to the potential complexity of such setup, we do not provide support for VPN environments. Please test the free ShareMouse demo version for compatibility with your system environment.

ShareMouse does not work over the internet. It is designed for multiple computers connected in local network.

ShareMouse only requires internet access during the short time of license registration and if you opted for the automatic check for software updates.

Of course, you can still access the internet while you use ShareMouse.

No, ShareMouse only transfers a few bytes of data which is required to send the XY mouse coordinates and keyboard input. Data is only sent if the mouse is actually moved or a key is pressed. You will not recognize any network slow down during use of ShareMouse.

However, if you use ShareMouse to drag & drop files or if you transmit large clipboard contents between computers, such data needs to be transmitted through your network connection which may temporarily affect your network, like if you would transmit the file without using ShareMouse.

Yes, ShareMouse v4 introduces macOS "Mojave" compatibility.

After upgrading to macOS "Mojave" you may need to perform the following steps:

  1. Open the macOS System Preferences » Security & Privacy.
  2. Go to the section Privacy " Accessibility.
  3. To make changes, open the padlock at the bottom left of the window (requires entering the administrator password).
  4. Remove the check mark from the ShareMouse entry and then set it again.
If this does not help:
  1. Remove the ShareMouse entry from the list by clicking the "-" button.
  2. Click the + button and add ShareMouse again.
  3. Restart your Mac.

ShareMouse works on system level and is not limited to specific applications. However, please take it for a test drive first, to verify, that ShareMouse works in your specific environment.

ShareMouse only works to a limited extent with screens shared with multiple computers.

Most multi-input displays pretend that each of the connected computers is activated, even if only one of the computers is actually displayed.

In order to change the mouse pointer between the computers, the pointer must first pass the invisible partof the desktop to appear on the neighbouring computer.

Background: The display input channel selector monitor is a display setting, not a setting of the operating system and the monitor does not communicate such setting. Therefore, applications running on the operating system, such as ShareMouse, do not know which computer the monitor is currently displaying.

Workaround: Use the Quickjump hotkey to switch between computers. Keep in mind, that the monitor letter is hidden for the computer currently not shown on the shared monitor.

ShareMouse includes optional password authorization and AES encryption to securely prevent unauthorized access by other ShareMouse installations.
