How I can save the homes and families in my computer so I can move to an external hard drive so you can drive to my computer game? So basically I want to move or save the homes and families of Sims 3 to another computer. PLEASE Help me!

Just watch for "Electronic Arts" folder "cut and paste" in a flash drive. Then install the game on your Mac for New Look "Electronics Arts folder and "paste" is in your flash drive that is the case. Should be asked if you want to replace the file and say yes to everything "
