To set Gmail in Chrome as the default email client on macOS, follow these steps:

1. Set Gmail as the Default Email Handler in Chrome

Gmail must first be configured as the email handler in Chrome:

1. Open Google Chrome and go to Gmail.
2. When you're on Gmail, look for the protocol handler icon (a two-diamond icon) in the Chrome address bar near the bookmarks star.
   • If you don't see it, skip to Step 3.

3. Click the protocol handler icon and select:

   • Allow Gmail to open all email links (e.g., mailto: links).
   • Click Done.

   Alternatively:

   • Open Chrome Settings > Privacy and Security > Site Settings > Additional Permissions > Handlers.
   • Make sure "Allow sites to ask to become default handlers for protocols" is enabled.
   • If Gmail isn't listed as a handler for mailto, revisit Gmail and check the protocol handler icon.

2. Set Chrome as the Default Web Browser

macOS uses the default web browser to handle mailto: links. To ensure Gmail opens in Chrome:

1. Open System Settings > Desktop & Dock.
2. Scroll down to Default web browser and set it to Google Chrome.

3. Disable Apple Mail as the Default Client

To prevent macOS from trying to use Apple Mail:

1. Open Mail (the Apple Mail app).
2. Go to the menu bar and click Mail > Settings (or Preferences).
3. In the General tab, locate Default email reader.
4. Click the dropdown and select Google Chrome.

4. Test the Setup

• Open any mailto: link (e.g., on a website).
• Ensure Gmail in Chrome opens automatically for composing the email.

Notes

• If Gmail still doesn’t open correctly, verify that Gmail is set as the default handler for email links in Chrome (Step 1).
• This method ensures all mailto: links and "Share via Email" actions on macOS redirect to Gmail in Chrome.

This should completely bypass Apple Mail and route email composition to Gmail in Chrome.
