Mac App Store Submission Guide
Since v0.34.0, Electron allows submitting packaged apps to the Mac App Store (MAS). This guide provides information on: how to submit your app and the limitations of the MAS build.
Note: From v0.36.0 there was a bug preventing GPU process to start after the app being sandboxed, so it is recommended to use v0.35.x before this bug gets fixed. You can find more about this in issue #3871.
Note: Submitting an app to Mac App Store requires enrolling Apple Developer Program, which costs money.
How to Submit Your App
The following steps introduce a simple way to submit your app to Mac App Store. However, these steps do not ensure your app will be approved by Apple; you still need to read Apple's Submitting Your App guide on how to meet the Mac App Store requirements.
Get Certificate
To submit your app to the Mac App Store, you first must get a certificate from Apple. You can follow these existing guides on web.
Sign Your App
After getting the certificate from Apple, you can package your app by following Application Distribution, and then proceed to signing your app. This step is basically the same with other programs, but the key is to sign every dependency of Electron one by one.
First, you need to prepare two entitlements files.
child.plist
:
<?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">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
<key>com.apple.security.inherit</key>
<true/>
</dict>
</plist>
parent.plist
:
<?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">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
</dict>
</plist>
And then sign your app with the following script:
#!/bin/bash
# Name of your app.
APP="YourApp"
# The path of you app to sign.
APP_PATH="/path/to/YouApp.app"
# The path to the location you want to put the signed package.
RESULT_PATH="~/Desktop/$APP.pkg"
# The name of certificates you requested.
APP_KEY="3rd Party Mac Developer Application: Company Name (APPIDENTITY)"
INSTALLER_KEY="3rd Party Mac Developer Installer: Company Name (APPIDENTITY)"
FRAMEWORKS_PATH="$APP_PATH/Contents/Frameworks"
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/Electron Framework.framework/Versions/A"
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/$APP Helper.app/"
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/$APP Helper EH.app/"
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/$APP Helper NP.app/"
if [ -d "$FRAMEWORKS_PATH/Squirrel.framework/Versions/A" ]; then
# Signing a non-MAS build.
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/Mantle.framework/Versions/A"
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/ReactiveCocoa.framework/Versions/A"
codesign --deep -fs "$APP_KEY" --entitlements child.plist "$FRAMEWORKS_PATH/Squirrel.framework/Versions/A"
fi
codesign -fs "$APP_KEY" --entitlements parent.plist "$APP_PATH"
productbuild --component "$APP_PATH" /Applications --sign "$INSTALLER_KEY" "$RESULT_PATH"
If you are new to app sandboxing under OS X, you should also read through Apple's Enabling App Sandbox to have a basic idea, then add keys for the permissions needed by your app to the entitlements files.
Upload Your App and Submit for Review
After signing your app, you can use Application Loader to upload it to iTunes Connect for processing, making sure you have created a record before uploading. Then you can submit your app for review.
Limitations of MAS Build
In order to satisfy all requirements for app sandboxing, the following modules have been disabled in the MAS build:
crashReporter
autoUpdater
and the following behaviors have been changed:
- Video capture may not work for some machines.
- Certain accessibility features may not work.
- Apps will not be aware of DNS changes.
Also, due to the usage of app sandboxing, the resources which can be accessed by the app are strictly limited; you can read App Sandboxing for more information.
Cryptographic Algorithms Used by Electron
Depending on the country and region you are located, Mac App Store may require documenting the cryptographic algorithms used in your app, and even ask you to submit a copy of U.S. Encryption Registration (ERN) approval.
Electron uses following cryptographic algorithms:
- AES - NIST SP 800-38A, NIST SP 800-38D, RFC 3394
- HMAC - FIPS 198-1
- ECDSA - ANS X9.62–2005
- ECDH - ANS X9.63–2001
- HKDF - NIST SP 800-56C
- PBKDF2 - RFC 2898
- RSA - RFC 3447
- SHA - FIPS 180-4
- Blowfish - https://www.schneier.com/cryptography/blowfish/
- CAST - RFC 2144, RFC 2612
- DES - FIPS 46-3
- DH - RFC 2631
- DSA - ANSI X9.30
- EC - SEC 1
- IDEA - "On the Design and Security of Block Ciphers" book by X. Lai
- MD2 - RFC 1319
- MD4 - RFC 6150
- MD5 - RFC 1321
- MDC2 - ISO/IEC 10118-2
- RC2 - RFC 2268
- RC4 - RFC 4345
- RC5 - http://people.csail.mit.edu/rivest/Rivest-rc5rev.pdf
- RIPEMD - ISO/IEC 10118-3
On how to get the ERN approval, you can reference the article: How to legally submit an app to Apple’s App Store when it uses encryption (or how to obtain an ERN).
