Migration issues!
I migrated all my stuff into my new mac from my old mac by using my WiFi network with the Migration Assistant. All went well. However, I plan on giving my old computer to my husband, but I noticed when I try to delete anything off my old computer it deletes from the new one. I tried restarting the old computer thinking that's all that was needed, but now I'm guessing I need to go into preferences, or soemthing? Help!
