What is easiest way to clean up an iMac to give to a trusted family member?
I want to give my iMac to a granddaughter and she is trustworthy. I have gotten rid of contacts, photos, emails, unwanted safari addresses but what is the easiest way to clean it up so there is none of my personal information left on it?
iMac, OS X Yosemite (10.10.3)
