WinExpat Download

Your fingers never emigrated.

You moved to a Mac. Or maybe you never quite will, because work keeps you on Windows all day with the Mac sitting right next to it. Either way, your muscle memory stayed behind. WinExpat brings the whole reflex set over and teaches you the local dialect while you work.

Native Swift, no account, no telemetry.

The WinExpat switcher open over three Mac windows, showing a live preview of each window with the second one selected.

Nothing to declare

What your hands currently get on a stock Mac, in full.

  • D nothing happens
  • PrtScn silence
  • Alt F4 the window survives
  • E still nothing
  • Home the cursor doesn’t move
  • Ctrl Esc no Task Manager
  • F2 the file keeps its name
  • L the screen stays unlocked

Every switcher knows this list by heart. WinExpat ends it.

Twenty-eight reflexes, one menu-bar app

AltTab gives you the switcher. DockDoor gives you dock previews. WinExpat gives you your hands back: the switcher, the snapping, the  key, the screenshots, the editing chords, the file habits. All of it, and each one is a checkbox you can turn off.

Snapping that speaks fluent

throws the window to the left half. Arrow again for quarters. Snap assist then offers the rest of your windows for the other side. It’s the actual Windows behaviour on macOS, with your key playing the key.

Snap left, and snap assist offers you the other half.

Dock peek, like the taskbar you mourn

Rest the pointer on a Dock icon and every window of that app pops up as a live preview, with a count in the header so you finally know how many Finder windows you actually have open. Click one and you’re there.

It teaches you the local language

Every time WinExpat catches a Windows chord, it can whisper the native one back at you. One day you’ll flick like a local, and you’ll probably keep WinExpat around anyway for the snapping.

And if Windows is still your day job, skip the lessons. WinExpat is just as happy being permanent: one reflex set for both machines, nothing to unlearn on Monday morning. For the fully committed there’s a switch that swaps Ctrl and outright, system-wide — every remap that just became redundant politely stands down.

The phrasebook

Square keys are what your hands do. Rounded keys are what the Mac wanted all along. WinExpat handles the first column and teaches you the last.

Got a keyboard in front of you? Press Alt, Ctrl or and the rows it belongs to light up. Yes, that is the whole product in one gesture.

A minute to settled

Three steps, no paperwork. Unusual, for an immigration process.

  1. Download & open

    One 1.8 MB disk image. No wizard, no Next-Next-Finish, and nobody asks you to create an account.

  2. Drag to Applications, open

    It’s signed and notarized, so Gatekeeper lets it through. If your Mac still frowns, right-click and choose Open. First dates are always a little awkward.

  3. Grant two permissions

    Accessibility for switching, snapping and hotkeys. Screen Recording for the live window previews. Both prompts appear on first launch; your reflexes work the moment you say yes.
