 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

-
-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:
-

-
-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.

-title: 'ASAR Integrity'
-description: 'An experimental feature that ensures the validity of ASAR contents at runtime.'
-slug: asar-integrity
-hide_title: false
----
-
-## Platform Support
-
-Currently ASAR integrity checking is only supported on macOS.
-
-## Requirements
-
-### Electron Forge / Electron Packager
-
-If you are using `>= electron-packager@15.4.0` or `>= @electron-forge/core@6.0.0-beta.61` then all these requirements are met for you automatically and you can skip to [Toggling the Fuse](#toggling-the-fuse).
-
-### Other build systems
-
-In order to enable ASAR integrity checking you need to ensure that your `app.asar` file was generated by a version of the `asar` npm package that supports asar integrity.  Support was introduced in version `3.1.0`.
-
-Your must then populate a valid `ElectronAsarIntegrity` dictionary block in your packaged apps `Info.plist`.  An example is included below.
-
-```plist
-<key>ElectronAsarIntegrity</key>
-<dict>
-  <key>Resources/app.asar</key>
-  <dict>
-    <key>algorithm</key>
-    <string>SHA256</string>
-    <key>hash</key>
-    <string>9d1f61ea03c4bb62b4416387a521101b81151da0cfbe18c9f8c8b818c5cebfac</string>
-  </dict>
-</dict>
-```
-
-Valid `algorithm` values are currently `SHA256` only.  The `hash` is a hash of the ASAR header using the given algorithm.  The `asar` package exposes a `getRawHeader` method whose result can then be hashed to generate this value.
-
-## Toggling the Fuse
-
-ASAR integrity checking is currently disabled by default and can be enabled by toggling a fuse. See [Electron Fuses](fuses.md) for more information on what Electron Fuses are and how they work.  When enabling this fuse you typically also want to enable the `onlyLoadAppFromAsar` fuse otherwise the validity checking can be bypassed via the Electron app code search path.
-
-```js
-require('@electron/fuses').flipFuses(
-  // E.g. /a/b/Foo.app
-  pathToPackagedApp,
-  {
-    version: FuseVersion.V1,
-    [FuseV1Options.EnableEmbeddedAsarIntegrityValidation]: true,

@@ -8,52 +8,6 @@ For a subset of Electron functionality it makes sense to disable certain feature
 
 Fuses are the solution to this problem, at a high level they are "magic bits" in the Electron binary that can be flipped when packaging your Electron app to enable / disable certain features / restrictions.  Because they are flipped at package time before you code sign your app the OS becomes responsible for ensuring those bits aren't flipped back via OS level code signing validation (Gatekeeper / App Locker).
 
-## Current Fuses
-
-### `runAsNode`
-
-**Default:** Enabled
-**@electron/fuses:** `FuseV1Options.RunAsNode`
-
-The runAsNode fuse toggles whether the `ELECTRON_RUN_AS_NODE` environment variable is respected or not.  Please note that if this fuse is disabled then `process.fork` in the main process will not function as expected as it depends on this environment variable to function.
-
-### `cookieEncryption`
-
-**Default:** Disabled
-**@electron/fuses:** `FuseV1Options.EnableCookieEncryption`
-
-The cookieEncryption fuse toggles whether the cookie store on disk is encrypted using OS level cryptography keys.  By default the sqlite database that Chromium uses to store cookies stores the values in plaintext.  If you wish to ensure your apps cookies are encrypted in the same way Chrome does then you should enable this fuse.  Please note it is a one-way transition, if you enable this fuse existing unencrypted cookies will be encrypted-on-write but if you then disable the fuse again your cookie store will effectively be corrupt and useless.  Most apps can safely enable this fuse.
-
-### `nodeOptions`
-
-**Default:** Enabled
-**@electron/fuses:** `FuseV1Options.EnableNodeOptionsEnvironmentVariable`
-
-The nodeOptions fuse toggles whether the [`NODE_OPTIONS`](https://nodejs.org/api/cli.html#node_optionsoptions) environment variable is respected or not.  This environment variable can be used to pass all kinds of custom options to the Node.js runtime and isn't typically used by apps in production.  Most apps can safely disable this fuse.
-
-### `nodeCliInspect`
-
-**Default:** Enabled
-**@electron/fuses:** `FuseV1Options.EnableNodeCliInspectArguments`
-
-The nodeCliInspect fuse toggles whether the `--inspect`, `--inspect-brk`, etc. flags are respected or not.  When disabled it also ensures that `SIGUSR1` signal does not initialize the main process inspector.  Most apps can safely disable this fuse.
-
-### `embeddedAsarIntegrityValidation`
-
-**Default:** Disabled
-**@electron/fuses:** `FuseV1Options.EnableEmbeddedAsarIntegrityValidation`
-
-The embeddedAsarIntegrityValidation fuse toggles an experimental feature on macOS that validates the content of the `app.asar` file when it is loaded.  This feature is designed to have a minimal performance impact but may marginally slow down file reads from inside the `app.asar` archive.
-
-For more information on how to use asar integrity validation please read the [Asar Integrity](asar-integrity.md) documentation.
-
-### `onlyLoadAppFromAsar`
-
-**Default:** Disabled
-**@electron/fuses:** `FuseV1Options.OnlyLoadAppFromAsar`
-
-The onlyLoadAppFromAsar fuse changes the search system that Electron uses to locate your app code.  By default Electron will search in the following order `app.asar` -> `app` -> `default_app.asar`.  When this fuse is enabled the search order becomes a single entry `app.asar` thus ensuring that when combined with the `embeddedAsarIntegrityValidation` fuse it is impossible to load non-validated code.

-
-Electron will set a default menu on startup with some standard entries. But there are reasons your application might want to change that and it will benefit startup performance.
-
-#### Why?
-
-If you build your own menu or use a frameless window without native menu, you should tell Electron early enough to not setup the default menu.
-
-#### How?
-
-Call `Menu.setApplicationMenu(null)` before `app.on("ready")`. This will prevent Electron from setting a default menu. See also https://github.com/electron/electron/issues/35512 for a related discussion.

+alongside privileged ones. By default, renderer processes are not sandboxed, but
+utility processes are. Note that as in Chromium, the main (browser) process is
+privileged and cannot be sandboxed.
+
+Historically, this mixed sandbox approach was established because having Node.js available
+in the renderer is an extremely powerful tool for app developers. Unfortunately, this
+feature is also an equally massive security vulnerability.
+
+Theoretically, unsandboxed renderers are not a problem for desktop applications that
+only display trusted code, but they make Electron less secure than Chromium for
+displaying untrusted web content. However, even purportedly trusted code may be
+dangerous — there are countless attack vectors that malicious actors can use, from
+cross-site scripting to content injection to man-in-the-middle attacks on remotely loaded
+websites, just to name a few. For this reason, we recommend enabling renderer sandboxing
+for the vast majority of cases under an abundance of caution.
+
+<!--TODO: update this guide when #28466 is either solved or closed -->
+Note that there is an active discussion in the issue tracker to enable renderer sandboxing
+by default. See [#28466][issue-28466]) for details.
 
 ## Sandbox behaviour in Electron
 
@@ -28,17 +46,12 @@ When renderer processes in Electron are sandboxed, they behave in the same way a
 regular Chrome renderer would. A sandboxed renderer won't have a Node.js
 environment initialized.

 Therefore, when the sandbox is enabled, renderer processes can only perform privileged
 tasks (such as interacting with the filesystem, making changes to the system, or spawning
 subprocesses) by delegating these tasks to the main process via inter-process
 communication (IPC).
