Utility for creating Universal macOS applications from two x64 and arm64 Electron applications

Usage no npm install needed!

<script type="module">
  import electronUniversal from 'https://cdn.skypack.dev/@electron/universal';



Create universal macOS Electron applications



import { makeUniversalApp } from '@electron/universal';

await makeUniversalApp({
  x64AppPath: 'path/to/App_x64.app',
  arm64AppPath: 'path/to/App_arm64.app',
  outAppPath: 'path/to/App_universal.app',


The app is twice as big now, why?

Well, a Universal app isn't anything magical. It is literally the x64 app and the arm64 app glued together into a single application. It's twice as big because it contains two apps in one.

What about native modules?

The way @electron/universal works today means you don't need to worry about things like building universal versions of your native modules. As long as your x64 and arm64 apps work in isolation the Universal app will work as well.
