I want to give my 2009 27" iMac to my daughter. What should I do to remove my mail so the iMac can be "hers"? What else should I remove and reset?
This should help guide you What to do before selling or giving away your Mac - Apple Support
Additionally, since yours came with install disks, you need to remove any OS or app you've downloaded from the app store because the license is for your use only and not transferable - it would present the buyer with problems if they needed to reinstall or update as all of that would still be tied to your Apple ID. So, you need to erase your hard drive and reinstall the original OS - your daughter can then upgrade the OS using her own Apple ID.
How do I prepare an 27" iMac for sale?
