# Signing macOS builds # Signing & notarizing macOS builds
Before signing macOS builds, you must do the following: Properly preparing macOS applications for release requires two steps: First, the
app needs to be code-signed. Then, the app needs to be uploaded to Apple for a
process called "notarization", where automated systems will further verify that
your app isn't doing anything to endanger its users.
To start the process, ensure that you fulfill the requirements for signing and
notarizing your app:
1. Enroll in the [Apple Developer Program] (requires an annual fee) 1. Enroll in the [Apple Developer Program] (requires an annual fee)
2. Download and install [Xcode] 2. Download and install [Xcode] - this requires a computer running macOS
3. Generate, download, and install [signing certificates] 3. Generate, download, and install [signing certificates]
There are a number of tools for signing your packaged app: Electron's ecosystem favors configuration and freedom, so there are multiple
ways to get your application signed and notarized.
- [`electron-osx-sign`] is a standalone tool for signing macOS packages. ## `electron-forge`
- [`electron-packager`] bundles `electron-osx-sign`. If you're using `electron-packager`,
pass the `--osx-sign=true` flag to sign your build.
- [`electron-forge`] uses `electron-packager` internally, you can set the `osxSign` option
in your forge config.
- [`electron-builder`] has built-in code-signing capabilities. See [electron.build/code-signing](https://www.electron.build/code-signing)
## Notarization If you're using Electron's favorite build tool, getting your application signed
and notarized requires a few additions to your configuration. [Forge](https://electronforge.io) is a
collection of the official Electron tools, using [`electron-packager`],
[`electron-osx-sign`], and [`electron-notarize`] under the hood.
Starting with macOS Catalina, Apple requires applications to be notarized. Let's take a look at an example configuration with all required fields. Not all
"Notarization" as defined by Apple means that you upload your previously signed of them are required: the tools will be clever enough to automatically find a
application to Apple for additional verification _before_ distributing the app suitable `identity`, for instance, but we recommend that you are explicit.
to your users.
To automate this process, you can use the [`electron-notarize`] module. You ```json
do not necessarily need to complete this step for every build you make  just {
the builds you intend to ship to users. "name": "my-app",
"version": "0.0.1",
"config": {
"forge": {
"packagerConfig": {
"osxSign": {
"identity": "Developer ID Application: Felix Rieseberg (LT94ZKYDCJ)",

},
"osxNotarize": {
"appleId": "felix@felix.fun",
"appleIdPassword": "my-apple-id-password",
}
}
}
}
}
```
The `plist` file referenced here needs the following macOS-specific entitlements
to assure the Apple security mechanisms that your app is doing these things
without meaning any harm:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<true/>

</plist>
```
To see all of this in action, check out Electron Fiddle's source code,
[especially its `electron-forge` configuration
file](https://github.com/electron/fiddle/blob/master/forge.config.js).
## `electron-builder`
Electron Builder comes with a custom solution for signing your application. You
can find [its documentation here](https://www.electron.build/code-signing).
## `electron-packager`
If you're not using an integrated build pipeline like Forge or Builder, you
are likely using [`electron-packager`], which includes [`electron-osx-sign`] and
[`electron-notarize`].
If you're using Packager's API, you can pass [in configuration that both signs
and notarizes your
application](https://electron.github.io/electron-packager/master/interfaces/electronpackager.options.html).
```js
const packager = require('electron-packager')
packager({
dir: '/path/to/my/app',
osxSign: {
identity: 'Developer ID Application: Felix Rieseberg (LT94ZKYDCJ)',
'hardened-runtime': true,
entitlements: 'entitlements.plist',
'entitlements-inherit': 'entitlements.plist',
'signature-flags': 'library'
},
osxNotarize: {
appleId: 'felix@felix.fun',
appleIdPassword: 'my-apple-id-password'
}
