electron-osx-sign
Codesign Electron macOS apps
About
electron-osx-sign
minimizes the extra work needed to eventually prepare your apps for shipping, providing the most basic tools and assets. Note that the bare necessities here are sufficient for enabling app sandbox, yet other configurations for network access etc. require additional work.
Check out electron-osx-sign
guide for suggestions on setting up your environment and workflow for distribution or development.
Please visit our wiki for walk-throughs, notes and frequently asked questions from past projects shipped with electron-packager
and electron-osx-sign
.
NB: Since electron-osx-sign
injects the entry com.apple.security.application-groups
into the entitlements file as part of the pre-signing process, this would reportedly limit app transfer on iTunes Connect (see #150). However, opting out entitlements automation opts['pre-auto-entitlements'] === false
may result in worse graphics performance.
The signing procedure implemented in this package is based on what described in Mac App Store Submission Guide.
It is worth noting as well that starting from Electron v1.1.1, a new mechanism was introduced to allow IPC in App Sandbox (see electron#5601); wish to have full support of legacy Electron versions, please utilize opts.version
, which option brings less hassle with making default settings among Electron builds.
We are trying to keep updated to the latest Electron specs; please file us an issue if having any suggestions or experiencing difficulties code signing your products.
Individuals making significant and valuable contributions are given commit-access to the project to contribute as they see fit. This project is more like an open wiki than a standard guarded open source project.

Thanks to seanchas116, jasonhinkle, and develar for improving the usability of this project implementation.
Installation
npm install --save electron-osx-sign
npm install -g electron-osx-sign
Note: electron-osx-sign
is a dependency of electron-packager
as of 6.0.0 for signing apps on macOS. However, feel free to install this package globally for more customization beyond specifying identity and entitlements.
Usage
electron-osx-sign
From the Command Line
electron-osx-sign app [embedded-binary ...] [options ...]
Examples
Since electron-osx-sign
adds the entry com.apple.developer.team-identifier
to a temporary copy of the specified entitlements file (with the default option --pre-auto-entitlements
) distribution builds can no longer be run directly. To run the app codesigned for distribution locally after codesigning, you may manually add ElectronTeamID
in your Info.plist
and com.apple.security.application-groups
in the entitlements file, and provide the flag --no-pre-auto-entitlements
for electron-osx-sign
to avoid this extra bit. Note that "certain features are only allowed across apps whose team-identifier value match" (Technical Note TN2415).
The examples below assume that --pre-auto-entitlements
is enabled.
-
To sign a distribution version by default:
electron-osx-sign path/to/my.app
For distribution in the Mac App Store: Have the provisioning profile for distribution placed in the current working directory and the signing identity installed in the default keychain. The app is not expected to run after codesigning since there is no provisioned device, and it is intended only for submission to iTunes Connect.
For distribution outside the Mac App Store: Have the signing identity for distribution installed in the default keychain and optionally place the provisioning profile in the current working directory. By default App Sandbox is not enabled. The app should run on all devices.
-
To sign development version:
electron-osx-sign path/to/my.app --type=development
For testing Mac App Store builds: Have the provisioning profile for development placed in the current working directory and the signing identity installed in the default keychain. The app will only run on provisioned devices.
For testing apps for distribution outside the Mac App Store, have the signing identity for development installed in the default keychain and optionally the provisioning profile placed in the current working directory. The app will only run on provisioned devices. However, you may prefer to just go with signing a distribution version because the app is expected to launch properly after codesigned.
-
It is recommended to place the provisioning profile(s) under the working directory for electron-osx-sign
to pick up automatically; however, to specify provisioning profile to be embedded explicitly:
electron-osx-sign path/to/my.app --provisioning-profile=path/to/my.provisionprofile
-
To specify the entitlements file:
electron-osx-sign path/to/my.app --entitlements=path/to/my.entitlements
-
It is recommended to make use of --version
while signing legacy versions of Electron:
electron-osx-sign path/to/my.app --version=0.34.0
Run electron-osx-sign --help
or see electron-osx-sign-usage.txt for CLI-specific options.
From the API
var sign = require('electron-osx-sign')
sign(opts[, function done (err) {}])
Example:
var sign = require('electron-osx-sign')
sign({
app: 'path/to/my.app'
}, function done (err) {
if (err) {
return;
}
})
From release v0.4.0-beta, Bluebird promises are introduced for better async method calls; the following is also available for use.
var signAsync = require('electron-osx-sign').signAsync
signAsync(opts)
[.then(function () {})]
[.catch(function (err) {})]
Example:
var signAsync = require('electron-osx-sign').signAsync
signAsync({
app: 'path/to/my.app'
})
.then(function () {
})
.catch(function (err) {
})

Default to the same entitlements file used for signing the app bundle.
entitlementsForFile
- Function

Flag to enable/disable Gatekeeper assessment after signing the app. Disabling it is useful for signing with self-signed certificates.
Gatekeeper assessment is enabled by default on darwin
platform.

).
If provided as an array, each item should be a string corresponding to a component.
Default to true
.
timestamp
- String
Specify the URL of the timestamp authority server, default to server provided by Apple. Please note that this default server may not support signatures not furnished by Apple.
Disable the timestamp service with none
.
type
- String

Allowed values: development
, distribution
.
Default to distribution
.
version
- String
Build version of Electron.
Values may be like: 1.1.1

It is recommended to utilize this option for best support of specific Electron versions. This may trigger pre/post operations for signing: For example, automation of setting com.apple.security.application-groups
in entitlements file and of updating Info.plist
with ElectronTeamID
is enabled for all versions starting from 1.1.1
; set pre-auto-entitlements
option to false
to disable this feature.

Debug
As of release v0.3.1, external module debug
is used to display logs and messages; remember to export DEBUG=electron-osx-sign*
when necessary.
Test
The project's configured to run automated tests on CircleCI.
If you wish to manually test the module, first comment out opts.identity
in test/basic.js
to enable auto discovery. Then run the command npm test
from the dev directory.
When this command is run for the first time: electron-download
will download macOS Electron releases defined in test/config.json
, and save to ~/.electron/
, which might take up less than 1GB of disk space.
A successful testing should look something like:
$ npm test
> electron-osx-sign@0.4.17 pretest electron-osx-sign
> rimraf test/work
> electron-osx-sign@0.4.17 test electron-osx-sign
> standard && tape test
Calling electron-download before running tests...
