Tool Overview

MacCtrlCVA is a lightweight macOS menu bar app for users who frequently switch between Windows and macOS. It maps familiar Windows-style shortcut habits to native macOS commands, so common editing operations can continue to feel natural on a Mac.

The app runs in the macOS menu bar and works system-wide after Accessibility permission is granted.

Key Features

  • Remaps Control + C/V/X/A/Z to native macOS editing shortcuts.
  • Supports configurable Fn + C/V/X/A/Z mappings in v2.0.0.
  • Supports choosing shortcut mappings from the menu bar.
  • Remaps Option + Tab to Command + Tab for Windows-style app switching.
  • Uses Control + Shift to switch to the next enabled input source.
  • Uses physical key codes, helping shortcuts work across input methods such as English and Chinese Pinyin.
  • Supports enable / disable controls and launch-at-login from the menu bar.

Installation

  1. Download the latest .dmg from the GitHub Releases page.
  2. Open the DMG and drag MacCtrlCVA.app into Applications.
  3. Launch the app.
  4. If macOS blocks first launch, right-click MacCtrlCVA.app, choose Open, and confirm the security prompt.
  5. Grant Accessibility permission in System Settings > Privacy & Security > Accessibility.

Technical Notes

MacCtrlCVA uses a global Quartz Event Tap to listen for keyboard events system-wide. When a supported shortcut is detected, the original event is suppressed and a synthetic event with the corresponding macOS modifier is posted.

For input source switching, the app uses macOS input source APIs directly instead of simulating characters, making Control + Shift switching more reliable across keyboard layouts and input methods.
