ShareMouse allows you to shut down multiple computers simultaneously:
A security count-down allows you to cancel any automated shutdown.
How to sync shutdown
Install the ShareMouse software and enable shutdown synchronization in the settings on all computers. The ShareMouse software then runs silently running in the background.
Whenever any computer is shut down, ShareMouse shows a count down on all other computers and shut them down after the grace period.
So much more than syncing shutdown
ShareMouse does not only sync the shutdown but also allows you to share the mouse and keyboard of any computer with any other computer on your desk.
ShareMouse works from any Windows or Mac computer to any other computer in any direction. You can also drag & drop files between computers.
