 #### Local production build of the MacOS desktop app
-In order to compile a production desktop build, run `npm run desktop-build`, this will generate a production app in the `dist/Mac` folder named `Chat.app`.
+The commands used to compile a production or staging desktop build are `npm run desktop-build` and `npm run desktop-build-staging`, respectively. These will product an app in the `dist/Mac` folder named NewExpensify.dmg that you can install like a normal app.
+
+HOWEVER, by default those commands will try to notarize the build (signing it as Expensify) and publish it to the S3 bucket where it's hosted for users. In most cases you won't actually need or want to do that for your local testing. To get around that and disable those behaviors for your local build, apply the following diff:

+
+1. Update `NEW_EXPENSIFY_URL` in `.env.staging`, setting it to the URL where the development web app can be found. This URL will vary based on whether you're testing for Apple or Google
+    - For Google, use http://localhost:8082 (make sure the port matches whatever you see in the browser when you run `npm run web`)
+    - For Apple, see [Configure the SSH tunneling](#configure-the-ssh-tunneling)
+2. Download and install the latest version of [SwiftDefaultApps](https://github.com/Lord-Kamina/SwiftDefaultApps?tab=readme-ov-file#installing--uninstalling).
+3. Open `System Settings` => `Swift Default Apps` => `URI Schemes` => `new-expensify` and select `New Expensify.app`
+4. Note that a dev build of the desktop app will not work. You'll create and install a local staging build:
+   1. Update `build-desktop.sh` replacing `--publish always` with `--publish never`. 
+   2. Run `npm run desktop-build-staging` and install the locally-generated desktop app to test.

-#### Set Environment to something other than "Development"
-
-The `DeepLinkWrapper` component will not handle deep links in the development environment. To be able to test deep linking, you must set the environment to something other than "Development".
-
-Within the `.env` file, set `envName` to something other than "Development", for example:

-#### Handle deep links in dev on MacOS
+Unlike with Apple, to test Google Sign-In we don't need to set up any http/ssh tunnels. We can just use `localhost`. But we need to set up the web and desktop environments to use `localhost` instead of `dev.new.expensify.com`
 
-If developing on MacOS, the development desktop app can't handle deeplinks correctly. To be able to test deeplinking back to the app, follow these steps:
-
-1. Create a "real" build of the desktop app, which can handle deep links, open the build folder, and install the dmg there:
-
-```shell
-npm run desktop-build
-open desktop-build
-# Then double-click "NewExpensify.dmg" in Finder window
-```
-
-2. Even with this build, the deep link may not be handled by the correct app, as the development Electron config seems to intercept it sometimes. To manage this, install [SwiftDefaultApps](https://github.com/Lord-Kamina/SwiftDefaultApps), which adds a preference pane that can be used to configure which app should handle deep links.
