A Mouse Without Borders alternative that works on a Mac
If you searched for "Mouse Without Borders for Mac," here's the short answer: there isn't one. It's Windows-only, and there's no macOS version. For a Mac + Windows PC desk, EasyKVM does the same one-keyboard-one-mouse job across both platforms. Unlike Mouse Without Borders, it can also switch one monitor's input between the two machines. $29.99 once.
What Mouse Without Borders does, and where it stops
Mouse Without Borders is a free Microsoft Garage utility (now also available inside Microsoft PowerToys) that shares one keyboard and mouse across up to four Windows computers, with clipboard sharing and file transfer between them. For an all-Windows desk it's hard to argue with: it's free and it does the job.
The two limits that send people searching for an alternative: it runs only on Windows (add a Mac to your desk and it's out), and it never touches your monitor. It assumes every PC has its own screen; it can't flip a shared display from one computer to the other.
EasyKVM covers both gaps: a Mac and a Windows PC, each with its own screen or sharing one monitor. Press a hotkey and keyboard, mouse, audio, and clipboard hand off to the other machine. On a shared monitor the input switches over DDC/CI on the same key. It all runs over your LAN, with no traffic leaving your network and no telemetry.

When Mouse Without Borders is the right choice
Honestly: if every computer on your desk runs Windows and each has its own screen, install Mouse Without Borders and keep your $29.99. It supports up to four PCs where EasyKVM currently pairs two, it transfers files between machines (EasyKVM doesn't), and it costs nothing. Being a Microsoft Garage side project rather than a fully supported product hasn't stopped it working well for years, and its move into PowerToys makes it even easier to install.
EasyKVM earns its price in the setups Mouse Without Borders can't cover: a Mac anywhere in the mix, or two computers sharing one monitor where you want the screen, keyboard, mouse, and audio to all swap together on one hotkey. Try it free for 3 days (no card), and there's a 14-day refund if your monitor turns out not to cooperate. EasyKVM is in beta.
