When you first launch Chrome in macOS, you should see a prompt like the one below to set Chrome as your default browser, which Tech Department recommends.
If you did not see that prompt, or want to change your default browser to Chrome, follow the steps below:
1. On your computer, open Chrome
2. In the top right corner, click the three dots
3. Click Settings
4. On the left side of the screen, in the "Default browser" section
5. Click "Make default" to make Chrome your default browser
Please note: If you don't see the button, Google Chrome is already your default browser.
