I changed my password and now I'm unable to receive any email on my mac pro but I am able to receive email on my iphone and iPad, any suggestions?

You changed your email password? Then you're going to have to re-enter it on the Mac(book?) Pro. If you're using Apple Mail, click the Mail menu, click Preferences, then Accounts, and enter the new password where you see the Password field. You'll also need to re-enter it in the Outgoing Mail Server section - click the dropdown list, click Edit SMTP Server List, click your account's SMTP server, click Advanced, and enter the new password.

You should also find that, if your password is incorrect, there's a lightning bolt or exclamation mark next to the Inbox. If you click that, you should be prompted for the new password. Same thing when you try to send a message for the first time.
