If you can't receive mail in the Mail app on your Mac
Find the name of your iCloud account on the left side of the main Mail window. If your account name is dimmed and has a lightning-bolt symbol next to it, your account is offline. To take your account online, connect to the Internet, then choose Mailbox > Take All Accounts Online. If you still need help, use these steps:
- Choose Mail > Preferences.
- Click the Accounts tab.
- Select your iCloud account from the list of accounts.
