Download for Windows

via GitHub Releases, our only official download source

Why GitHub? The buttons above download directly from the public easykvm-releases repo, the only place we publish builds: same files that your account page links to after purchase. If a third-party site offers an EasyKVM download, treat it as untrusted.

After you install

You need EasyKVM running on both computers. Each OS asks for a couple of one-time confirmations on first run. Here's exactly what to expect.

On the Mac

  1. First open: EasyKVM isn't notarized by Apple yet, so macOS blocks the first launch. Open the app once; it'll be blocked. Go to System Settings → Privacy & Security, scroll down to "EasyKVM was blocked to protect your Mac", and click Open Anyway. Confirm with your password or Touch ID. This is one time per version.
  2. If macOS says the app "is damaged and can't be opened": open Terminal and run xattr -d com.apple.quarantine /Applications/EasyKVM.app (adjust the path if EasyKVM isn't in Applications), then open it normally.
  3. Accessibility permission: macOS requires it to inject keyboard and mouse events. EasyKVM prompts when you first mirror. Grant it in System Settings → Privacy & Security → Accessibility.
  4. Audio (optional): forwarding Mac audio to the PC uses ScreenCaptureKit, which needs Screen Recording permission. macOS prompts the first time you turn audio on.

On the Windows PC

  1. SmartScreen: Windows may show "Windows protected your PC" because EasyKVM isn't code-signed with an EV certificate yet, so SmartScreen flags the unknown publisher. Click More info (small text under the warning), then Run anyway. One time per version.
  2. Firewall: allow EasyKVM through Windows Defender Firewall when prompted on first launch, so the two machines can talk over your LAN.

Then pair them

  1. Both machines on the same LAN (same router; Wi-Fi works, wired feels snappiest).
  2. Press Create connection on the host machine. It shows a 6-digit code.
  3. Type the code on the other computer within 5 minutes (codes expire; just generate a new one if it does).
  4. Press the swap hotkey (default Ctrl+Alt+Q) to switch. Press again to come back.

How the trial works

Three days of full functionality, enough to confirm the parts that depend on your hardware (DDC/CI monitor switching, pairing, keyboard mirror). No credit card, no account, no sign-up.

After the trial, the host machine needs a license: $29.99, one-time. No subscription, and it covers both Mac and Windows. The other computer never needs a license or an account; it just joins over the LAN. There's also a 14-day refund if EasyKVM doesn't work with your setup, no questions asked. If you're still weighing this against a hardware box, the KVM switch for two computers guide covers the port matching you skip.
