+By default, if an app of the same name as the one being moved exists in the Applications directory and is _not_ running, the existing app will be trashed and the active app moved into its place. If it _is_ running, the preexisting running app will assume focus and the previously active app will quit itself. This behavior can be changed by providing the optional conflict handler, where the boolean returned by the handler determines whether or not the move conflict is resolved with default behavior.  i.e. returning `false` will ensure no further action is taken, returning `true` will result in the default behavior and the method continuing.

+> Register for and receive notifications from remote push notification services
+
+For example, when registering for push notifications via Apple push notification services (APNS):
+
+```javascript
+const { pushNotifications, Notification } = require('electron')
+
+pushNotifications.registerForAPNSNotifications().then((token) => {

+### `pushNotifications.registerForAPNSNotifications()` _macOS_

+
+Registers the app with Apple Push Notification service (APNS) to receive [Badge, Sound, and Alert](https://developer.apple.com/documentation/appkit/sremotenotificationtype?language=objc) notifications.

 ### I'm being asked for a username/password for chromium-internal.googlesource.com
 
 If you see a prompt for `Username for 'https://chrome-internal.googlesource.com':` when running `gclient sync` on Windows, it's probably because the `DEPOT_TOOLS_WIN_TOOLCHAIN` environment variable is not set to 0. Open `Control Panel` → `System and Security` → `System` → `Advanced system settings` and add a system variable
 `DEPOT_TOOLS_WIN_TOOLCHAIN` with value `0`.  This tells `depot_tools` to use
 your locally installed version of Visual Studio (by default, `depot_tools` will

+
+### Xcode "incompatible architecture" errors (MacOS arm64-specific)
+
+If both Xcode and Xcode command line tools are installed (`$ xcode -select --install`, or directly download the correct version [here](https://developer.apple.com/download/all/?q=command%20line%20tools)), but the stack trace says otherwise like so:
+
+```sh

+```
+
+If you are on arm64 architecture, the build script may be pointing to the wrong Xcode version (11.x.y doesn't support arm64). Navigate to `/Users/<user>/.electron_build_tools/third_party/Xcode/` and rename `Xcode-13.3.0.app` to `Xcode.app` to ensure the right Xcode version is used.

+
+The `entitlements.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 title="entitlements.plist"
+<?xml version="1.0" encoding="UTF-8"?>

+  </dict>
+</plist>
+```
+
+Note that up until Electron 12, the `com.apple.security.cs.allow-unsigned-executable-memory` entitlement was required
+as well. However, it should not be used anymore if it can be avoided.
+
+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).
+
+If you plan to access the microphone or camera within your app using Electron's APIs, you'll also

+<true/>
+<key>com.apple.security.device.camera</key>

+If these are not present in your app's entitlements when you invoke, for example:
+
+```js title="main.js"

+const microphone = systemPreferences.askForMediaAccess('microphone')

-# Distributing Apps With Electron Forge
-
-Electron Forge is a tool for packaging and publishing Electron applications.
-It unifies Electron's build tooling ecosystem into
-a single extensible interface so that anyone can jump right into making Electron apps.
-
-## Getting started
-
-The [Electron Forge docs] contain detailed information on taking your application
-from source code to your end users' machines.
-This includes:
-
-* Packaging your application [(package)]
-* Generating executables and installers for each OS [(make)], and,
-* Publishing these files to online platforms to download [(publish)].
-
-For beginners, we recommend following through Electron's [tutorial] to develop, build,
-package and publish your first Electron app. If you have already developed an app on your machine
-and want to start on packaging and distribution, start from [step 5] of the tutorial.
-
-## Getting help
-
-* If you need help with developing your app, our [community Discord server][discord] is a great place
-to get advice from other Electron app developers.
-* If you suspect you're running into a bug with Forge, please check the [GitHub issue tracker]
-to see if any existing issues match your problem. If not, feel free to fill out our bug report
-template and submit a new issue.

+# Testing Widevine CDM
+
+In Electron you can use the Widevine CDM library shipped with Chrome browser.
+
+Widevine Content Decryption Modules (CDMs) are how streaming services protect
+content using HTML5 video to web browsers without relying on an NPAPI plugin
+like Flash or Silverlight. Widevine support is an alternative solution for
+streaming services that currently rely on Silverlight for playback of
+DRM-protected video content. It will allow websites to show DRM-protected video
+content in Firefox without the use of NPAPI plugins. The Widevine CDM runs in an
+open-source CDM sandbox providing better user security than NPAPI plugins.
+
+#### Note on VMP
+
+As of [`Electron v1.8.0 (Chrome v59)`](https://electronjs.org/releases#1.8.1),
+the below steps are may only be some of the necessary steps to enable Widevine;
+any app on or after that version intending to use the Widevine CDM may need to
+be signed using a license obtained from [Widevine](https://www.widevine.com/)
+itself.
+
+Per [Widevine](https://www.widevine.com/):
+
+> Chrome 59 (and later) includes support for Verified Media Path (VMP). VMP
+> provides a method to verify the authenticity of a device platform. For browser
+> deployments, this will provide an additional signal to determine if a
+> browser-based implementation is reliable and secure.
+>
+> The proxy integration guide has been updated with information about VMP and
+> how to issue licenses.
+>
+> Widevine recommends our browser-based integrations (vendors and browser-based
+> applications) add support for VMP.
+
+To enable video playback with this new restriction,
+[castLabs](https://castlabs.com/open-source/downstream/) has created a
+[fork](https://github.com/castlabs/electron-releases) that has implemented the
+necessary changes to enable Widevine to be played in an Electron application if
+one has obtained the necessary licenses from widevine.
+
+## Getting the library
+
+Open `chrome://components/` in Chrome browser, find `Widevine Content Decryption Module`
+and make sure it is up to date, then you can find the library files from the
+application directory.
+
+### On Windows
+
+The library file `widevinecdm.dll` will be under
+`Program Files(x86)/Google/Chrome/Application/CHROME_VERSION/WidevineCdm/_platform_specific/win_(x86|x64)/`
+directory.
+
+### On macOS
+
+The library file `libwidevinecdm.dylib` will be under
+`/Applications/Google Chrome.app/Contents/Versions/CHROME_VERSION/Google Chrome Framework.framework/Versions/A/Libraries/WidevineCdm/_platform_specific/mac_(x86|x64)/`
+directory.
+
+**Note:** Make sure that chrome version used by Electron is greater than or
+equal to the `min_chrome_version` value of Chrome's widevine cdm component.
+The value can be found in `manifest.json` under `WidevineCdm` directory.
+
+## Using the library
+
+After getting the library files, you should pass the path to the file
+with `--widevine-cdm-path` command line switch, and the library's version
+with `--widevine-cdm-version` switch. The command line switches have to be
+passed before the `ready` event of `app` module gets emitted.
+
+Example code:
+
+```javascript
+const { app, BrowserWindow } = require('electron')
+
+// You have to pass the directory that contains widevine library here, it is
+// * `libwidevinecdm.dylib` on macOS,
+// * `widevinecdm.dll` on Windows.
+app.commandLine.appendSwitch('widevine-cdm-path', '/path/to/widevine_library')
+// The version of plugin can be got from `chrome://components` page in Chrome.
+app.commandLine.appendSwitch('widevine-cdm-version', '1.4.8.866')
+
+let win = null
+app.whenReady().then(() => {
+  win = new BrowserWindow()
+  win.show()
+})
+```
+
+## Verifying Widevine CDM support
+
+To verify whether widevine works, you can use following ways:
+
+* Open https://shaka-player-demo.appspot.com/ and load a manifest that uses
+`Widevine`.
+* Open http://www.dash-player.com/demo/drm-test-area/, check whether the page
+says `bitdash uses Widevine in your browser`, then play the video.
