Welcome to JustAnwer.com, my name is ***** ***** I will do my best to assist you.
Before I suggest anything, Id like you to explain what happened when you were hacked. What did you see.
What symptoms did you notice? Was it just an email account that was hacked, or did you see strange screens or viruses running on your mac, or in your Safari browser?
Thank you in advance for this additional, detailed information.
