This guide assumes you've already setup your email accounts through cPanel. If you have not first created your email addresses please refer to our KB article How do I create or configure email addresses? for a guide on that process.
You can then follow Apple's official guide at https://support.apple.com/en-us/HT204093 for configuring an email account on your Mac. You will select the option "Other Email Account" and then use the details provided in cPanel to configure your email address hosted with Hawk Host through Mac mail.
