Is there a way to double check the Apple to make sure this hacker did not put something
on the apple. I do not understand how a hacker gets in the AOL email again after password was changed.
And just to send spam advertising out to all mail contacts.
Unless you opened an email attachment nothing should be on your Mac. Email providers are hacked regularly, gmail has been hit at least twice this year alone. Periodically changing yourpasswordsis a big help. You can also do a restart of your Macto make sure anything that is running in the background is stopped.
